Commissioned Report No. 400 (iBids no. 1370)

Contractor: Seastar Survey Ltd.

Year of publication: 2010

Background

In September 2008 a No Take Zone (NTZ) was established in Lamlash Bay (Isle of Arran, North Ayrshire) in Scotland following a consultation for a fishery order (under the Inshore Fishing (Scotland) Act 1984). The proposed NTZ was passed by the Scottish Parliament prohibiting all sea fishing within the NTZ. Scottish Natural Heritage has a commitment to contribute to the monitoring of the No Take Zone in Lamlash Bay and the purpose of the current study is to inform the design and initiation of the monitoring of the Lamlash Bay NTZ, which will establish the future success of the management measures in delivering benefits to both the biodiversity of the bay and the scallop fishery in the wider area. The current study involved an acoustic mapping survey with ground-truthing (camera deployments and sediment sampling) to create maps of the habitats and biotopes within the site in a Geographical Information System (GIS).

Main findings

• The ground-truthing of the sidescan sonar data revealed a heterogeneous sediment environment with sand dominating the central and southern Lamlash Bay and mixed coarse sediments dominating the northern Lamlash Bay and North Channel.

• Nine biotopes were recognised during the ground-truthing (using drop-down camera) of the 2008 and 2009 sidescan sonar data: CR.LCR.BrAs.AmenCio, CR.LCR.BrAs.AmenCio.Bri, SS.SMx.CMx.ClloMx(Nem), SS.SMX.CMx.OphMx, SS.SMP.Mrl.Pcal, SS.SMu.CSaMu.(AfilMysAnit), SS.SSa.CMuSa.(AbraAirr), SS.SMP.KSwSS.LsacR.CbPb and SS.SMP.KSwSS.LsacR.Sa.

• All Lamlash Bay NTZ Day grab locations were classified as ‘sand’ according to the Folk sediment classification system (greater than 80%); with fine and very fine sand being the dominant ‘sand’ categories.

• Two further biotopes have tentatively been classified among the NTZ Day grab locations as SS.SSa.CMuSa.(AalbNuc) and SS.SMx.CMx.(MysThyMx).

• Maerl beds, dominated by Phymatolithon calcareum, were identified in the northern Lamlash Bay, North Channel and the Lamlash Outer regions as well as along the northern, eastern and southern coastline of Holy Island.

• Based on comparisons with the few previous studies the sediment environment and the faunal communities are similar overall.

• Recommendations are made regarding future monitoring including repeat drop-down camera (still photography and video) and sediment sampling surveys at 2 year intervals.

1 INTRODUCTION

1.1 Project background Seastar Survey Ltd. was contracted by Scottish Natural Heritage (SNH) to conduct a habitat mapping survey of Lamlash Bay and the adjacent area, Isle of Arran (figure 1). The survey follows the establishment of a No Take Zone (NTZ) via the Inshore Fishing (Prohibition on Fishing) (Lamlash Bay) (Scotland) Order 2008. This Order was introduced by the Scottish Parliament on 20th September 2008 and prohibits all forms of fishing within the NTZ (figure 2 and table 1). The aim of the survey was to carry out a baseline survey in Lamlash Bay to describe the seabed environment and map the seabed habitats in Lamlash Bay. The survey will inform the monitoring of the area to establish the success of the management measure in delivering benefits to both the biodiversity of the bay and the scallop fishery in the area. The survey area encompasses the whole of Lamlash Bay and an area outside the bay extending approximately 1 mile beyond the northern and southern entrances of the bay and seawards to the 30 m contour (figure 1), with the NTZ (figure 2) given the highest priority. Figure 1. Lamlash Bay located on the east coast of the Isle of Arran (Firth of Clyde) in North Ayrshire, Scotland.

In order to record and characterise the habitats in Lamlash Bay, Seastar Survey Ltd. undertook an acoustic and a ground-truthing survey (sediment sampling and video/still photography surveys) in 2008. Additional acoustic and camera surveys were carried out in 2009 to acquire data in the areas not surveyed in 2008. The aim of the acoustic element of the survey was to identify different backscatter returns and describe as well as delineate the extent of the various seabed habitat types occurring in and around Lamlash Bay. A digital sidescan sonar mosaic, in conjunction with single beam echo sounder derived bathymetry, provided the initial broadview to map the substrata present throughout the survey area as well as allowing the identification of any features of interest. The aim of the ground-truthing element of the survey was to provide a description of the richness and diversity of the habitats on both rocky reef and the softer sediments. The biotope distribution and species composition was developed through interpretation of drop-down video footage and digital still photography, taken after evaluation of the sidescan mosaic. Sediment samples (Day grabs) collected in 2008 were analysed to ground-truth the sidescan sonar data as well as describe and quantify the infaunal communities in the NTZ. The results of all elements of the survey were used to create a Geographical Information System (GIS) which enabled a high level of processing, interpretation and display of the sidescan sonar mosaic, bathymetry, substrata types, biotopes and the digital photography. 1.2 The environment Lamlash Bay is located on the east coast of the Isle of Arran in North Ayrshire, Scotland. Arran is the largest island in the Firth of Clyde, the most southerly fjord in the northern hemisphere (COAST, 2005). Arran is sheltered from the Atlantic by the Kintyre Peninsula and separated from mainland Scotland by the Firth of Clyde to the east and the Sound of Bute and the mouth of Loch Fyne to the north (Gazetteer for Scotland, 2008). The island is 36 km in length and 22 km wide (COAST, 2005). Lamlash Bay is approximately 5 km across, bounded by the headlands of Clauchlands Point to the north and Kingscross point to the south (COAST, 2005; Gazetteer for Scotland, 2008). Over half of the bay is occupied by Holy Island which is approximately 3 km long and 1.5 km wide (COAST, 2005; Gazetteer for Scotland, 2008).

1.2.1 Geology and the sedimentary environment

There is limited published information regarding the seabed environment in Lamlash Bay, however, the northern and southern margins of the bay are dominated by rocky coastlines with sublittoral rock being present along the northern coast and the northern channel (Duncan, 2003). The south-western coast of Holy Island consists of a steep rocky slope that descends to 20 m below chart datum (Duncan, 2003). On admiralty charts the seabed within the bay is generally dominated by mud and sand with additions of broken shell particularly in the southern area of Lamlash Bay and along the western side of Holy Island. The North Channel and the outer reaches of the survey area are dominated by mixed sediments (sand, mud, broken shell and gravel). These records seem to be in overall agreement with the observations made by Duncan (2003), reporting the sediment to be primarily composed of soft sediments with sand being the most common sediment type. Areas of mixed sediment (rock, cobble and mud) and other areas dominated by boulders have also been identified (see Duncan, 2003), the latter being a feature not identified on the admiralty chart.

1.2.2 The physical environment

The maximum water depth in Lamlash Bay is 43 m below chart datum (admiralty charts) with the majority of the area being > 20 m deep below chart datum. Shallower sills exist at the northern and southern entrances to the bay. The sill at the southern entrance of the bay has a maximum water depth of 25 m below chart datum, at the northern entrance to the bay water depths are recorded as 11.3 m below chart datum (Seasearch 2003, COAST 2005). Current speeds range from approximately 0.5 knots (neap tides) to 0.75 knots (spring tides) at the entrance of the North Channel and from 0.75 knots (neap tides) to 1.5 knots (springs) at the entrance of the South Channel.

1.2.3 Biological distributions

There is a limited amount of published information regarding the biological distributions in Lamlash Bay and prior to 2003 no records existed for Lamlash Bay within the Marine Nature Conservation Review (MNCR) database (now recorded as NBN Marine Recorder) (Duncan, 2003; COAST, 2005). In 2003, however, Seasearch divers surveyed 21 sites in Lamlash Bay (results given in figure 3) to create a basic sublittoral baseline for the area (Duncan, 2003). The sites are marked by flags with the small blue circles illustrating the exact position of the site location. Sites with maerl are highlighted in purple and scallops (abundance estimated as ‘common’ and/or noteworthy on the Seasearch forms) in brown (locations 6-8, 10, 12, 14 and 20). Sites with both maerl and scallops (‘common’) were recorded in blue (sites 7 and 16) and sites with both sea grass and maerl were recorded in green (2). All other sites were recorded in orange (see Duncan (2003) for further details). Figure 3. Seasearch survey sites in Lamlash Bay (from Duncan, 2003).


5

Of particular note is the presence of maerl and sea grass (Zostera sp.) beds in the North Channel as well as the presence of ‘reefs’ (e.g. Deacon Rock). Although none of the species recorded in Lamlash Bay are listed as Annex II species in the EC Habitats Directive, both maerl and Zostera sp. are listed on the UK Biodiversity Action Plan (UKBAP) Habitat Action Plan as priority habitats (UKBAP, 2008) and included in the Scottish Biodiversity List (BiodiversityScotland, 2008). In addition to being listed as a priority habitat on the UKBAP’s Habitat Action Plan, maerl beds are covered by four different habitat types of Annex I of the EC Habitats Directive ‘sandbanks which are slightly covered by seawater at all times’, ‘large shallow bays and inlets’; ‘estuaries’ and the priority habitat ‘lagoons’ (UKBAP, 2008). Apart from the ecologically important species such as Phymatolithon (maerl) and Zostera sp. (eelgrass), other taxa recorded in the bay (see Duncan, 2003) include Cerianthus lloydii, Metridium senile, Echinus esculentus and species in the subphylum Pisces (fish); dogfish, conger eels (Conger conger), leopard-spotted gobies (Thorogobius ephippiatus), pipefish (Syngnathinae), gurnards (Triglidae), dragonets (Callionymus lyra) and plaice (Pleuronectes platessa) as well as commercially important species such as scallops (Pectinidae), edible crabs (Cancer pagurus) and flatfish (Pleuronectiformes).

The 2008 field work (acoustic and biological surveys) was undertaken between the 13th and 21st October 2008 with all survey operations conducted from the Fisheries Research Services’ (FRS) survey vessel Alba na Mara. The survey mobilisation and de-mobilisation took place in Ardrossan Harbour, Scotland on 13th October and 21st October respectively. During the survey the vessel anchored overnight in either Lamlash Bay or Brodick Bay. The draught of Alba na Mara restricted the 2008 survey operations to areas outside the 10 m contour. The additional survey work required to acquire baseline environmental data from the shallow sections (areas inside the 10 m contour) was carried out in 2009. The 2009 field work (acoustic and drop-down camera surveys) was undertaken between 9 and 13 September 2009 with all survey operations conducted from Seastar Survey Ltd.’s vessel Otarie. The survey mobilisation and de-mobilisation took place in Ardrossan Harbour, Scotland, on 7th September and 14th September respectively. 2.1 The acoustic surveys The acoustic surveys in 2008 and 2009 were carried out using a Leica 1200 RTK Rover GPS system and an EdgeTech FS 4200 dual frequency sidescan sonar system (see appendix 1 for detailed equipment specifications) but the echosounder used in 2008 was a Simrad EK60 split beam echosounder whilst the 2009 echosounder system comprised a Marimatech E-Sea Sound 206 dual frequency echosounder (33/200 kHz). The 2008 acoustic survey area was divided into four main areas of planned acoustic lines (figure 4 and table 2) to simplify survey operations. SNH defined the area within the NTZ as the priority survey area. The survey effort was therefore structured to ensure that the acoustic and ground-truthing was completed in its entirety within the NTZ in the event that the survey work was delayed preventing the completion of the survey work in the remainder of the area.

The 2009 acoustic survey was divided into nine different areas (A – I) and the locations of these lines were selected in the planning stage of the project (see figure 5 and table 3). As previously, SNH defined the area within the NTZ as the priority survey area. The survey effort was again structured to ensure that the acoustic and ground-truthing was completed in its entirety within the NTZ in the event that the survey work was delayed preventing the completion of the survey work in the remainder of the study area.

2.1.1 Horizontal control

Horizontal control was achieved using a Leica Real Time Kinematic (RTK) GPS (GX1230 Real Time Rover System). In 2008 the GPS antenna was mounted on the handrail on the upper deck above the bridge (on Alba na Mara) and in 2009 it was pole-mounted at the stern of Mariner to ensure a signal could be received from the maximum number of satellites available. The GPS obtained a satellite derived position in WGS84 latitude and longitude which was recorded using the Hypack 2008 survey management software. A data transformation was undertaken within the Hypack software using the Ordnance Survey model OSTN02 to convert from WGS84 latitude and longitude to OSGB36 easting and northing. A known position within Ardrossan Harbour was obtained from the Ordnance Survey in OSGB36 grid coordinates. A navigation check was then carried out against that known position at the start and the end of the survey to check the accuracy of the RTK GPS signal (see navigation checks in appendix 02).

2.1.2 Vertical control

2.1.2.1 Tides

Tide corrections were achieved via the vertical component of the RTK GPS. The raw bathymetric soundings produced by the echosounder were reduced relative to Ordnance Datum Newlyn (ODN) using the Ordnance Survey OSGM02 model within Hypack. This allowed for the tidal component to be removed from the raw soundings in real-time (see example of tidal curve in appendix 02).

2.1.2.2 The 2008 split beam echosounder

Vertical control during the 2008 survey was achieved using the Alba na Mara’s Simrad EK60 scientific split beam echosounder (38/200 kHz) with the coverage of the survey illustrated in figures 4 and 5. The vessels echosounder transducers are pole mounted in a pod fitted to a shaft which enabled the pod to be deployed to 1 m below the keel to improve acoustic performance. When the echosounder pole was down the transducers were approximately 5.25 m below the sea surface. It was intended that the high frequency (200 kHz) channel would be used for the survey. However, the data provided by the high frequency channel was found to experience signal loss when the vessel was moving; therefore the low frequency (38 kHz) data was recorded for the duration of the survey. The speed of sound through the water column was measured each day using a Marimatech HMS 1820-P CTD. Additional sound velocity profiles were taken when the survey vessel moved to a different survey area. The sound velocity profiles have been applied to the bathymetric data during processing within the Hypack survey management software. The bathymetric soundings were reduced relative to ODN to account for the effect of tide in real-time within Hypack, via the vertical component of the RTK GPS. Hypack applied the real time corrections using the Ordnance Survey OSGM02 model.

2.1.2.3 The 2009 dual frequency echosounder

Vertical control during the 2009 survey was achieved using a Marimatech E-Sea Sound dual-frequency (33 and 200 kHz) digital echosounder. Data from both frequencies were recorded on a paper trace and digitally using the Hypack survey management software. The echosounder transducer was pole mounted over the port side of the vessel and secured using fore and aft stays to prevent any movement of the transducer head. Bathymetric survey coverage from the 2008 and 2009 surveys are illustrated in figure 4 and 5. The bathymetric soundings were reduced relative to ODN to account for the effect of tide in real-time within Hypack, via the vertical component of the RTK GPS. Hypack applied the real time corrections using the Ordnance Survey OSGM02 model. The speed of sound through the water column was measured each day using a Marimatech HMS 1820-P CTD. Additional sound velocity profiles were taken when the survey vessel moved to a different survey area. The sound velocity will be applied to the bathymetric data during processing within the Hypack survey management software.

2.1.3 Vessel motion reference

Possible errors in the bathymetric data relating to vessel motion were minimised by the use of a TSS CMS 25 Compact Motion Sensor, to account for any vessel motion to an accuracy of ±5 cm. Corrections due to vessel motion have been applied during processing using the Hypack software.

2.1.4 Sidescan sonar

Seabed backscatter data was collected using an EdgeTech 4200-FS dual frequency (120/410 kHz) sidescan sonar. During the survey the unit was operated using the high frequency at 410 kHz. The system comprised a towfish, a slip-ring winch carrying 700 m of coax cable and transceiver. The sidescan data was viewed in real-time through Hypack. Heading and layback information were also provided through Hypack. Data was recorded in HS2 format (Hypack sidescan data file). In 2008 the line spacing was set at 50 m with a range of 50 m (covering 50 m either side of the fish – 100m swath). The line spacing allowed for 100 % overlap of the sidescan data with adjacent lines. The towfish was deployed from the Alba na Mara’s CTD winch. The towfish was lowered into the water by the ships crew. Once the towfish was at the sea surface control of the winch was transferred to winch controls in the survey lab, which were operated by the surveyor. The sidescan was towed at speeds of 4-5 knots. The line spacing in 2009 was set at 50 m with a range of 100 m (covering 100 m either side of the fish creating a 200 m swath). The line spacing allowed for a 200% overlap of the sidescan data with adjacent lines. The towfish was deployed from a capstan winch on a rope and connected to the surface using a 200 m soft tow cable which was deployed at the same rate as the rope. As in 2008 the sidescan was towed at speeds of 4-5 knots. The sidescan sonar survey resulted in a coverage illustrated in figures 6 and 7 (see survey limitations below).

2.1.5 Weather conditions

The weather conditions in both 2008 and 2009 were overall suitable for survey operations to take place throughout the survey periods. The only exceptions were on 19 October 2008 when weather downtime was incurred as a result of strong wind (Force 7 - 8), rough seas (moderate – rough), heavy rain and poor visibility; and on 8 September 2009 when strong winds (Force 6 – 8), a rough sea state (rough or very rough) and moderate to poor visibility prevented survey operations from taking place. In these conditions it was deemed unsafe for the vessel to continue with camera work or to carry out grabbing and survey operations were ceased.

2.1.6 Processing and charting

Processing of the bathymetric data was undertaken using the post processing tools within the survey management software. This was undertaken with reference to the echo sounder paper trace records as part of our quality control procedures. The processing of the data involved editing out the water column, the removal of spikes and other erroneous points from the data and the reduction of the depths using corrected data acquired from the RTK. The data were then imported into an ArcView GIS for display and interpretation. The sidescan sonar data were initially processed and mosaiced within the survey management software. This involved trimming the edges wherever possible and appropriate as well as mosaicing the sidescan traces together to obtain a map as complete as possible with a resolution of 2 m bins (i.e. 1 pixel equals 2 m of seafloor). Paper print-outs and a GeoTiff were delivered. This data was then also imported into the ArcView GIS, and again the GIS was used as the medium of display and ongoing data analysis and interpretation. 2.2 Drop-down camera survey methodology

2.2.1 Drop-down camera system

The camera equipment used during the survey was a Kongsberg Simrad OE14-208 Digital Stills Camera System mounted obliquely on a seabed camera frame (figure 8). A flash unit and two sub-sea lights were also mounted on the frame. These units were linked to the surface with a soft umbilical cable. All controls of the camera system were kept in the wheelhouse of the survey vessel.

2.2.2 Camera operation and deployment

The two drop-down camera surveys were carried out between 16th and 20th October 2008 and 9th and 13th September 2009 respectively. The camera system was only deployed in suitable weather conditions by a team of experienced personnel. Before each deployment a ‘clapper board’ containing site name, date and weather conditions was videoed and photographed as a quality assurance (QA) record. All camera deployments (figures 9 and 10) were established as transects across sites of interest, which were selected after scrutinising the acoustic survey data (figures 6 and 7). The vessel was positioned at one end of each transect using DGPS. The camera was then deployed and lowered to the seabed. Once the camera system was at the seabed and had time to settle, the onboard surveyors started to log navigation and the skipper was given approval to start drifting along the transect at about 0.5 knots.

13



During the 2008 deployments, the control of the camera and winch were solely with the camera operator. The winch was controlled using a remote control, whilst photographs were taken using a surface trigger in the wheel house. The 2009 deployments were carried out manually (using a manual winch fitted on a davit) with verbal instructions given from the camera operator to the winch controller to direct the camera operations. The camera system sent a continuous, real-time, analogue video feed to the surface, where the deployment was monitored and the camera / winch were controlled. The analogue video feed was recorded digitally. In 2008 the signal was recorded using Mini Digital Video (miniDV) tapes and backed-up using super VHS tapes whilst in 2009 the signal was recorded on DVDs with a hard-disc recorder being used as a back-up. In 2008 the video was recorded to tape rather than DVD as the quality and life expectancy of tape is much greater but in 2009 this facility was not available. Individual still photographs were taken using a surface controlled trigger. Photographs were taken regularly at random along the transects to capture the general seabed environment and the fauna present but also at the discretion of the camera operator to capture particular taxa (to allow identification) and ensure that any changes in the seabed environment were recorded.

14

Throughout each camera deployment, navigation data was recorded. All camera deployment log keeping was synchronised to the navigation data using the time from the RTK GPS. The log keeper recorded the time from the GPS at the start and end of each deployment and the time each photograph was taken. After each deployment the camera was removed from the frame and secured in the wheel house. The digital photographs were then uploaded from the camera to a laptop computer via a USB lead (the software used for this was Canon Zoom Browser EX). During the upload process each photograph was named with the site-name and photograph number.

2.2.3 Data handling

The photographs and video footage were then used for analysis in the GIS. When the camera surveys were completed the miniDV tapes and DVDs were taken back to Seastar Survey Ltd. offices by a member of staff and the backup VHS tapes and hard drives were transported to an offsite data storage facility. After the survey the digital miniDV tapes were up-loaded to a computer, edited, titled and burnt to DVD as mpeg files. All DVDs, photographs and logs were checked for errors as part of Seastar Survey Ltd’s standard quality control procedures and all data supplied to the client. Finally the client was supplied with DVDs with mpeg video files, sets of all seabed photographs and the seabed photographs were also incorporated into the ArcView GIS. 2.3 Video and photographic analysis

2.3.1 Analysis of the photographs and video records

The analysis of the photographs and video records was carried out ‘blind’, without any prior knowledge of the sites, using a personal computer and a SONY digital videocassette recorder and a television monitor respectively. The latter system allows slow-motion, freeze-frame and standard play analysis. An initial assessment of a site was carried out by first looking through the photographs and film from the particular site quickly to get a brief understanding of the substratum, flora and fauna.

2.3.1.1 Semi-quantitative analysis of the video footage

The video analysis included an initial assessment of a deployment to get a broad understanding of the substratum, flora and fauna as well as the identification of the different biotopes/habitats on the seabed. The boundary positions of the different biotopes/habitats were determined using the time codes and related back to the navigation data. The detailed analysis consisted of a general seabed description and the fauna were identified to the lowest practical level. General descriptions of the faunal life-forms were made and any other features of interest such as trawl marks were also recorded. The abundance data were recorded using the SACFOR scale (general fauna) and actual abundance (commercial taxa) with the analysis concentrating on the commercially important species present together with species readily identified in the video material. A list of the encountered fauna was produced for each site using species reference numbers as cited in the Marine Conservation Society Species Directory (Howson and Picton 1997) to avoid problems in species nomenclature. The sections or deployments were subsequently classified into designated biotopes according to Connor et al. (2004). Faunal densities were calculated based on the distance covered for each habitat, biotope or transect, basing the calculations on the estimated assumption that the camera covers 1 m in width (previous

15

camera calibration test gives a seafloor coverage of approximately 0.8 m by 0.8 m when the camera frame is in contact with the seabed). The distances for each habitat were calculated from the position of the start of each habitat / biotope to the position of the end of each habitat / biotope rather than attempting to calculate the exact distance along the transect resulting in approximate density values.

2.3.1.2 Quantitative analysis of the stills photographs

The still photography analysis was carried out using a personal computer. The methodology is in large parts similar to the video analysis methodology described for the video analysis and included a general seabed description where the substrata were described according to the Wentworth scale (see Leeder, 1982) with boulders and cobbles being described within ‘gravel’ and rock referring to bedrock. The fauna was identified to the lowest practical level with the nomenclature according to the Marine Conservation Society Species Directory (Howson and Picton 1997) and actual abundance of the fauna and flora was recorded whenever possible (faunal densities are based on the approximation that each photograph covers 1 m2; see camera calibration notes above). The presence of faunal life-forms and any other features of interest such as trawl marks were also recorded. Each photograph was subsequently classified into designated biotopes according to Connor et al. (2004), wherever possible. These results were subsequently incorporated into the ArcView GIS. 2.4 Sediment sampling Sediment samples were taken in 2008 using a 0.1 m2 Day grab. Grab samples were taken at 10 locations across the NTZ (figure 11). The grab sites were selected to represent the different sediment types indicated by the sidescan sonar data and seabed video footage and to allow additional data for the biotope classification process. The number of sites was restricted to the NTZ as a result of limited funding but also as the photographic material at the shallow sites was considered to be of sufficient quality to allow biotope classification. A further consideration was the potential of damaging the maerl beds had the grab sampling survey been extended to include the shallow sections. Prior to deployment the grab was cleaned out using the vessels seawater deck wash to remove any remaining sediment or contamination. The Day grab was then deployed by the vessels crew from the crane on the port side of the vessel. The grab was lowered to the seabed until the cable went slack indicating that the grab had reached the seabed. The grab was then recovered to deck where the sample was inspected by the environmental scientist. Grab samples were rejected on the grounds of poor quality for the following reasons:

• Uneven surface indicative of striking the seabed at an angle

• Washed out sample

• Disturbed surface sediment

• Contamination of the sediment (e.g. hagfish, paint chips, oil)

• Sample touching the top of the grab

• Sample <40% of the grabs capacity If the grab sample was acceptable a photograph was taken with a sample label in the image indicating the sampling area and drop number. A small sub sample (approximately 100g) was taken from each of the grab samples for particle size analysis (PSA). The contents of the grab were then washed into a collecting tray under the grab stand. The sediment was gently washed over a 1 mm sieve. The material retained on the sieve was then transferred into a 5 dm3 (litres) plastic bucket and fixed using a 4 % buffered formaldehyde solution to prevent sample degradation.

16

Figure 11. Sediment sampling locations for the Lamlash Bay habitat mapping survey 2008.


The processing of the macrofaunal sediment samples took place at Seastar Survey’s laboratory in Southampton. The sediment samples were gently re-sieved on 1 mm sieves and sorted (using trays and low-magnification microscopes). The fauna was subsequently identified to the lowest practical level (species in most cases) with reference to the species directory (Howson and Picton, 1997) to avoid problems with nomenclature. A full list of taxa encountered and abundances per sample are recorded on a standard species / sample matrix (appendix 06) A reference collection was created and a Quality Control (QC) exercise was also carried out by Artoo Marine Ecological Consultants to check the identification results. The invertebrate specimens collected were separated by species and by station, preserved in alcohol, and stored in glass sample vials with polyethylene closures to facilitate their incorporation into the collections of The National Museum of Scotland. The particle size analysis also took place in Seastar Survey’s laboratory following standard protocols using a combination of wet and dry sieving techniques at 1 phi intervals. The PSA followed the sediment grades used by the MNCR (Marine Nature Conservation Review) as described below:

17

Pebble – medium (> 8 mm) Pebble – small (4-8 mm) Granule (2-4 mm)

Sand very coarse (1000-2000 µm)

Sand coarse (500-1000 µm)

Sand medium (250-500 µm)

Sand fine (125-250 µm)

Sand very fine (63-125 µm)

Silt and clay (mud) (<63 µm) The dry weight of the whole sediment sample was determined and any muddy samples were disaggregated using a suitable method (e.g. sodium hexametaphosphate). The sample was

wet sieved on a 63 µm mesh then dried and re-weighed to establish the weight percentage of

the sub 63 µm fraction. The remainder of the sample was dry sieved with an appropriate sequence of mesh sizes to yield weight percentage data for particle size fractions at half phi

intervals. This was done from a minimum sieve size of 63 µm to a maximum sieve size of 16 mm. 2.5 Data analysis Ecological interpretation of the results was carried out by reference to the JNCC Marine Nature Conservation Review Biotope Classification (Connor et al., 2004), and the presence of rare or unusual species identified against the list in Sanderson (1996). All the identified and enumerated benthic macrofauna were used in the analysis and the abundance data are given in the SACFOR scale (see Connor et al., 2004) for the video records and actual abundance, given as number of individuals/m2, for the still photographs. The macrofaunal sediment data are given in number of individuals/0.1 m2. The data analyses comprised both univariate and multivariate analyses all of which were calculated using Primer (Plymouth Routines in Multivariate Ecological Research) v 5.2.0 (Clarke and Warwick, 1994). The univariate analysis included the total number of individuals (N), total number of species (S), species diversity where the Shannon-Wiener (H’), Pielou’s (J) and Margalef’s (d) diversity indices (see e.g. Gage and Tyler, 1991; Fowler and Cohen, 1992; Clarke and Warwick, 1994) were used with the natural log (loge) being the chosen parameter in the case of the Shannon-Wiener diversity index. The multivariate analysis was carried out using cluster analysis and ordination (non-metric multi-dimensional scaling, MDS). These data were then transformed to square root to down-weigh the importance of common types of macrofauna in relation to rarer types. The transformed data were then analysed using the Bray-Curtis similarity coefficient (using Primer v.5) followed by a cluster analysis where the sites were group averaged and the resultant dendrogram plotted. Non-metric multi-dimensional scaling (MDS) was then carried out to further assess the presence of any similarities between sites (Clarke and Warwick, 1994). Spearman’s rank correlation coefficient (see e.g. Fowler and Cohen, 1992) was then used to assess any correlations with the particle size analysis variables. The BIOENV routine in PRIMER was used to carry out this task on untransformed abiotic data. The SIMPER routine in PRIMER was subsequently used to assess the difference in characteristic species/ taxa in the samples.

2.6 Survey limitations

2.6.1 Survey vessel

The main factor limiting the Lamlash Bay survey in 2008 was the use of the vessel Alba na Mara as the draught of the vessel (5.25 m with the transducer pole down) prevented any survey operations shallower than the 10 m contour. This excluded a large section of Lamlash Bay area from the survey including some areas in the north of the No Take Zone believed to be dominated by rocky ‘reef’ habitats (as defined in the European Habitats Directive 92/43/EEC). This issue was raised during the survey operations but after consultation SNH decided to complete the current stage of the survey using Alba na Mara. The second survey in 2009 using a different vessel was therefore required to cover the entire Lamlash Bay study area.

2.6.2 Obstructions

In 2008 a line of fishing pots prevented a large section in the centre of the Lamlash Outer (the survey area outside Lamlash Bay) from being surveyed. In addition, a section in the south-west was also excluded from the survey as a result of the presence of fish farm cages. In 2009 the planned lines C01 to C04 were not completed because of obstructions in the water associated with the mussel farm. Line B03 was cut short at the southern end as a result of the presence of mooring buoys. The presence of fishing pots obstructed lines D08, D09, D10 and D11, although sidescan sonar data were acquired from this area.

2.6.3 Equipment failure

During the 2009 survey the portside high frequency transmitter on the towfish failed (9 September 2009) and it was not possible to repair the towfish in the field. Drop-down camera operations were therefore conducted in the NTZ whilst waiting for a new sidescan sonar towfish to be delivered.

3 RESULTS

3.1 Acoustic analysis The processing and analysis of the acoustic data (bathymetric data and sidescan sonar mosaic) from the acoustic survey (410 kHz sidescan sonar and 38/200 kHz single beam echo sounder) revealed areas of different levels of backscatter, suggesting clear changes in bathymetry, sediment type and or sediment composition within the survey area (see figures 6 and 7). These patterns and features were used to direct the selection of deployment locations for the underwater video (see figure 9 and 10) and still photography system as well as the sediment grab sampling (see figure 11). The analysis of the sidescan sonar mosaic reveals a number of areas with a low backscatter return, particularly in the inner, deeper parts of Lamlash Bay (central and southern sections) whilst high backscatter returns are found in shallower water, particularly around the northern and southern sections of the North Channel, a number of small areas northwest of Holy Island and along the coast around Holy Island and in the Outer Lamlash area (see figures 6 and 7). To illustrate some of these features, both natural and anthropogenic, a number of targets (sections of the sidescan sonar mosaic) have been selected (figures 13 - 26) and the positions of the features are given in figure 12 (NB. the sidescan sonar images are displayed using inverted grey scale, therefore shadows appear black).

19

Figure 12. Sidescan sonar image with selected targets to illustrate some of the features identified in Lamlash Bay.


3.1.1 Target 1 - anchor sinkers

Two anchor sinker marks (approximately 1 m x 2 m in dimension with multiple chains) were noted at Target 1 in the southern part of Lamlash Bay (figure 13). The distance between the two sinkers is approximately 14 m. This is a good example of the detail and clarity of the data obtained by the sidescan sonar and illustrates one of the human activities / impacts in the bay.

20

Figure 13. Anchor sinkers seen in the southern section of Lamlash Bay (located approximately at East (X): 204779.6 and North (Y): 629190.2).

3.1.2 Target 2 - anchor drag marks

Anchor drag marks with sediment build up are present in the central and southern sections of Lamlash Bay (figure 14). This image is approximately 50 m wide with the anchor drag marks being approximately 58 m long. There are several of these drag marks across this section of the bay, some of which are over 200 m long. Figure 14. Anchor drag marks in the southern section of Lamlash Bay (located approximately at East (X): 204804.31 and North (Y): 629718.87).

21

3.1.3 Target 3 - scallop dredge marks

There is some evidence of fishing activity along the west coast of Holy Island, in this case scallop dredging activity, with the dredge marks (individual tracks are approximately 5 m wide) creating a circular pattern centred around a small mound (figure 15) just outside the survey area. The conical shapes of the positive targets also visible on the sidescan image are possibly a result of deposition of sediment material from the dredges. These features were detected at the outer limit of the sidescan sonar trace (as a result of the relatively large draught of the survey vessel) but the additional sidescan sonar coverage in the shallow water along the Holy Island west coast (in 2009) did not reveal any further evidence of this activity. Figure 15. Scallop dredge marks in the southern section of Lamlash Bay (circular pattern centred on East (X): 205270.52 and North (Y): 629791.71).

3.1.4 Target 4 - exposed bedrock

Target 4 is from North Channel and it consists of an area of high backscatter return with relief, surrounded by a low backscatter. This target has been interpreted as exposed bedrock and boulders surrounded by coarse (boulder, cobble and gravel debris) and soft sediment (sand) types (figure 16). The bedrock target is approximately 24 m long, 12 m wide and 1.8 m high.

22

Figure 16. Exposed bedrock near the shallow sill in North Channel in Lamlash Bay (located approximately at East (X): 206105.47 and North (Y): 632224.95).

3.1.5 Target 5 - Deacon Rock

Target 5 (figure 17) is a section (image width is approximately 100 m) of Deacon Rock with a mottled appearance of high and low backscatter with some relief discernable in the high backscatter returns. This seabed environment has been interpreted to consist of boulders (largest being approximately 0.8 m in height), cobbles and other coarse sediment types surrounded by sediments returning low backscatter, suggesting the presence of sand.

Figure 17. Deacon Rock in Lamlash Bay (located at East (X): 204509.00 and North (Y): 630898.00).

23

3.1.6 Target 6 - sediment furrows

Target 6 is from an area of sediment giving low backscatter returns, interpreting the sediment as sand. Figure 18 illustrates several sediment furrows (the approximate image dimensions are: 80 m in length and 60 m in width). The origin of these furrows is unknown. Figure 18. Sediment furrows in the centre of Lamlash Bay (located at East (X): 204081.00 and North (Y): 630704.00).

3.1.7 Target 7 - low backscatter return (sand)

The most predominant seabed sediment feature across Lamlash Bay is illustrated in figure 19 (the image is approximately 50 m wide). This low backscatter return is interpreted as muddy sand and a feature present throughout the central and southern sections of Lamlash Bay. These areas are interspersed with areas of coarser sediment (including gravel) and shell debris. Figure 19. An area of low backscatter return in the south of Lamlash Bay (located at East (X): 205989.00 and North (Y): 628454.00).

3.1.8 Target 8 - mottled high and low backscatter

Areas of mottled high and low backscatter are interpreted as gravel interspersed with sand. It is a seabed environment found across Lamlash Bay and in central and northern sections in particular; appearing as mottled high and low backscatter returns (figure 20). The image is approximately 50 m wide and the largest boulder is about 1 m in height (1.5 m wide and 2.5 m long). Figure 20. An area of high mottled backscatter return in the south of Lamlash Bay (located at East (X): 205110.26 and North (Y): 628864.17).

3.1.9 Target 9 - mottled high and low backscatter In some of the shallower areas of Lamlash Bay, such as the central region at Deacon Rock and southern and northern boundaries of North Channel, the seabed comprised areas of coarse sediment. This mottled high back scatter return with relief is interpreted as cobbles and small and large boulders, surrounded by sediments returning low backscatter, suggesting the presence of sand (figure 21). The images are approximately 100 m wide.

3.1.10 Target 10 - area of seabed with Maerl The strong returns and mottled appearance are indicative of very coarse sediment (figure 22). Maerl was found to be present at shallower regions, in particular to the north of Lamlash Bay (North Channel) where coarse sediment is present. The image (figure 22) is approximately 50 m across. Figure 22. An area of mottled backscatter to the North West of Lamlash Bay where maerl is present (located at East (X): 204581.00 and North (Y): 631678.00).

3.1.11 Target 11 – high backscatter area with maerl

Target 11 has been selected from the shallow bank in the north-eastern corner of Lamlash Bay. The image (figure 23) illustrates an area of mottled and high backscatter returns in a section of the seabed where maerl is present together with macroalgae (brown and red seaweed). The image is approximately 20 m across. Figure 23. An area of high backscatter on the shallow bank in the north-eastern Lamlash Bay where maerl is present (located at East (X): 205551.00 and North (Y): 632298.00).

3.1.12 Target 12 – mooring sinkers and chain

There were a number of obstructions during the field work period one of which was in the north-western corner of Lamlash Bay where a number of moorings were present. The presence of these moorings is illustrated in target 12 (figure 24) where mooring sinkers and chain can be seen. The image is approximately 20 m across.

3.1.13 Target 13 - coarse sediment with macroalgae and maerl

There is a shallow bank extending down from the southern tip of Holy Island. This shallow bank is dominated by coarse sediment (large and small boulders, cobbles and gravel) with macroalgae and maerl gravel (figure 25). The larger algae cover the seabed and prevent the identification of maerl in some areas but maerl is most likely present on the majority of this bank. The image is approximately 20 m wide. Figure 25. An area of mixed coarse sediment at the southern entrance of Lamlash Bay where maerl and macroalgae are present (located at East (X): 206527.00 and North (Y): 628297.00).

28

3.1.14 Target 14 – mixed seabed environment off Holy Island

The seabed around target 14 (figure 26) from the area to the north-east of Holy Island consists of mixed sediments. Some areas are dominated by a truly mixed sediment environment with muddy sandy gravel with some shell material but there are also sections of muddy sand with a different faunal community. The image is approximately 20 m wide. Figure 26. An area of mixed backscatter along the north-eastern coast off Holy Island (located at East (X): 205026.00 and North (Y): 631114.00).

3.2 Photographic and video analysis – ground-truthing

3.2.1 Ground-truthing of the sidescan sonar imagery

In 2008 a total of 19 miniDV tapes with approximately 11 hours of video footage were recorded during the drop-down camera survey and a total of 848 seabed still photographs (869 with clapper boards to identify each deployment) were taken at 22 different locations (figure 9 and table 4). The 2009 ground-truthing survey resulted in a total of just over 4 hours of video footage (recorded on DVD) and 278 still photographs (294 with clapper boards to identify each deployment) from 16 different locations (see figure 10 and table 5).

The selection of sidescan sonar targets (section 3.1) for illustration purposes was carried out subsequent to processing and analysis of the sidescan sonar data. The selection of ground-truthing using the camera was, however, carried out in the field prior to any detailed analysis of the sidescan sonar data. The selected targets in section 3.1 did therefore not always correspond directly to these targets as some features were not obvious on initial interpretation or there simply were too many desired targets to allow ground-truthing of all of them within the allocated survey period. However, the quality of the sidescan sonar images at most of these targets is sufficient to verify the identity of the features seen.

3.2.1.1 Target 5 - Deacon Rock

The photographic transect (LNC07) near Deacon Rock (figure 27) allows ground-truthing of target 5 (see figure 17) confirming the initial interpretation of a seabed environment with boulders and cobbles surrounded by sand. The species found on Deacon Rock include Ascidiacea, Antedon bifida, Ophiura sp., Munida rugosa, hydroids and various polychaetes. Figure 27. Ground-truthing of target 5 - Deacon Rock (photographs LNC07_26 and 32).

3.2.1.2 Target 7 - low backscatter return

Target 7 has been interpreted as sand and it is a widespread feature across the entire Lamlash Bay survey area. The ground-truthing photographs (example given in figure 28) verify the initial interpretation and illustrate sandy mud and fauna including Ophiura sp, Turritella communis, gobies and burrowing polychaetes. Figure 28. Ground-truthing of target 7 - low backscatter return (photograph LSC03_0020).

31

3.2.1.3 Target 8 - mottled high and low backscatter

The mottled high and low backscatter seen in target 8 has been interpreted as gravel, an interpretation confirmed in the photographs, exemplified by the photographs in figure 29. The fauna found in these areas include C. lloydii, various burrowing and tubiculous polychaetes, T. communis, Ascidiacea and the occasional E. esculentus and Liocarcinus puber. Figure 29. Ground-truthing of target 8 (photographs LNC05_48 and LSC04_49).

3.2.1.4 Target 9 - mottled high and low backscatter

The interpretation of target 9 (mottled high back scatter return with relief surrounded by low backscatter) was interpreted as cobbles and small and large boulders, surrounded by sand, features confirmed in the ground-truthing as given in figure 30. Fauna such as brittlestar and maerl beds are found on similar substrata together with hydroids, polychaetes, scallops, Liocarcinus spp. and T. communis as well as some red algae. Figure 30. Ground-truthing of target 9 (photographs LNC10_21 and LNC08_20).

32

3.2.1.5 Target 10 - area of seabed with maerl

The ground-truthing of target 10 confirms the initial interpretation of a seabed with strong backscatter returns and mottled appearance to be very coarse sediment (figure 31). Maerl was found at this location, a feature not visible on the sidescan sonar, but this type of seabed environment was shown to be relatively common in the northern and Outer Lamlash regions. Fauna associated with this habitat included hydroids, C. lloydii and polychaetes as well as some Liocarcinus spp. and scallops. Figure 31. Ground-truthing of target 10 (photograph LNC11_10).

3.2.1.6 Target 13 – area of seabed with maerl and seaweed

The shallow bank extending from the southern tip of Holy Island is most likely dominated by maerl and seaweed communities throughout although the ground-truthing using the drop-down camera only acquired footage along two transects (see figures 10 and 12). The video footage and still photographs confirm the presence of coarse sediment (small boulders, cobbles and gravel in particular) but also a seabed dominated by maerl, some of which is hard to identify as a result of the dense cover of large seaweed taxa in places (see figure 32). There is some live maerl present in this region (approximately 1 – 8%) but also patches of brittlestars (Ophiocomina nigra).

Figure 32. Ground-truthing of target 13 (photograph E01_05 and E01_19).

33

3.2.1.7 Target 14 – mixed sediment north-east of Holy Island

The sedimentary environment north-west of Holy Island is mixed, as predicted from the sidescan sonar imagery and confirmed by the photographic material. Some areas are dominated by a truly mixed seabed (muddy sandy gravel and shell) with fauna such as C. lloydii, T. communis, hydroids and polychaetes (see NTZ05_09 in figure 33). The other main sediment type (muddy sand) present is dominated by T. communis and Amphiura sp., a community similar to that seen in the centre of the bay (see NTZ05_18 in figure 33). Figure 33. Ground-truthing of target 14 (photograph NTZ05_09 and NTZ05_18).

3.2.2 General descriptions of the biological communities in Lamlash Bay

The analysis of the sidescan sonar mosaic, together with the ground-truthing using the photography (see summary of species in appendix 07) and video (see summary of biotopes in appendix 08) records, allowed for a detailed assessment of the habitats in Lamlash Bay. The interpretation of the mosaic and the ground-truthing revealed a number of features: 1) soft sediments dominated by muddy sand in central and southern regions of Lamlash Bay; 2) a mixture of sediment environments (muddy sand and mixed sediments) in the northern Lamlash Bay and Outer Lamlash Bay area with sections of rocks and brittlestar beds; 3) relatively small rocky reefs (including Deacon Rock); and 4) shallower areas / banks in northern Lamlash Bay, North Channel, Outer Lamlash Bay and the southern entrance to Lamlash Bay with maerl beds. The majority of the photographic / video transects cross a substratum boundary in an attempt to ground-truth more than one type of backscatter return in each deployment in order to increase sampling efficiency. This resulted in more than one habitat as well as different taxa present within each transect, making the descriptive tasks more complicated (see tables 6, 7 and 8).

3.2.2.1 Central and southern Lamlash Bay

The central and southern regions of Lamlash Bay are characterised by soft sediment, mainly muddy sand, and the dominant fauna include Amphiura sp., Ophiura sp., T. communis and polychaetes (figure 34 and table 6). However, the seabed is not uniformly muddy sand and there are several photographic transects that cross several (minor) boundaries both in terms of the substratum and fauna present. Transect LSC02 illustrate this point perfectly with the first section being dominated by Amphiura sp.; the second section being dominated by Ophiura sp. and T. communis; and the third section being dominated by T. communis. The

34

sediment appears to be the same in the first two sections but changes to a mixed type (muddy sand and gravel) in the third section. A total number of 5 biotopes have been recognised for this region of the survey area. The dominant types are SS.SSa.CMuSa.(AbraAirr), exemplified by photograph LSC01 (in figure 34) and SS.SMu.CSaMu.(AfilMysAnit), exemplified by photograph LSC02 (in figure 34). Both of these biotopes have been somewhat tentatively selected (hence the brackets) in the photographic analysis. The latter of the two has been selected rather than SS.SSa.CMuSa.AalbNuc (see Day grab samples below) as T. communis is common on the photographs at AfilMysAnit locations but it is not a taxa recorded in AalbNuc. These two biotopes appear to be very closely linked and grade into each other (Connor et al., 2004). The biotopes resulting from the Day grab and photographic survey may therefore be: 1) a combination of the two biotopes; or 2) different patches of the two biotopes in the same region. The difference between AbraAirr and AalbNuc is subtle but obvious on the photographs in the large number of Amphiura sp. present in the former. Furthermore, the sediment is slightly sandier in AbraAirr compared to AalbNuc. Table 6. Summary of the video and photographic analyses with the main substrata, fauna and biotope in central and southern Lamlash Bay.

3.2.2.2 Northern Lamlash Bay and North Channel

The northern Lamlash Bay and North Channel area consists of a very mixed seabed environment with substrata ranging from muddy sand to bedrock (figures 35 and 36 and table 7). The fauna is also different in different part of the area including T. communis, M. rugosa, C. lloydii, polychaetes, ascidians and maerl (figures 36 and table 7). A total of 6 biotopes have been classified for this area. The dominant biotopes are SS.SMu.CSaMu.(AfilMysAnit) and SS.SMx.CMx.ClloMx(Nem) but the maerl biotope (SS.SMP.Mrl.Pcal) is common in the shallower regions of the survey area and extends further into the infralittoral region (see figures 10 and 35). The maerl is dominant on the main (deeper) part of the banks but there is a mixture of maerl and macroalgae (brown and red seaweeds) in the shallowest areas. The circalittoral rock biotope CR.LCR.BrAs.AmenCio (exemplified by LNC10_06 and LNC11_20 in figure 36) has been selected rather than CR.LCR.BrAs.AntAsH as the latter is found in the most sheltered positions in sea lochs, in weak to very weak tidal currents and the fauna is slightly different to the AmenCio biotope. SS.SMu.CSaMu.(AfilMysAnit), exemplified by LNC05, LNC07 and LNC12 in figure 36, has been selected in the photographic analysis rather than SS.SSa.CMuSa.AalbNuc (see Day grab samples below) as T. communis is common on the photographs but it is not a taxa recorded in AalbNuc. These two biotopes appear to be very closely linked and grade into each other (Connor et al., 2004). The biotopes found here may therefore be: 1) a combination of the two; or 2) different patches of the two biotopes in the same region. The

36

classification of biotopes during the video analysis allowed classification only in lower levels in the hierarchy as less detail is visible in the videos compared to the still photographs (allowing zooming in).

3.2.2.3 Outer Lamlash Bay

The Outer Lamlash Bay area consists of a very mixed seabed environment with sections of muddy sand and other sections of mixed and coarse (with gravel, cobbles and boulders) substrata (see figure 37 and table 8). Two transects (LNC01* and LOC02) are dominated by muddy sand and taxa dominated by T. communis, M. rugosa and polychaetes. The other three transects are characterised by a mixed sediment (muddy sand and gravel with rocks in some areas) and with a varied faunal composition (maerl, featherstars, T. communis, O. nigra, C. lloydii and polychaetes). A total of 6 different biotopes have been classified in the Outer Lamlash Bay region (see comments about the selection of the various biotopes above). Photographic examples of the biotopes are given as follows: LOC03 exemplifies the SS.SMx.CMx biotope complex, photograph LNC01_56 exemplifies the CR.LCR.BrAs.AmenCio.Bri (see further examples below) sub-biotope and photograph LNC03_04 exemplifies the SS.SMx.CMx.ClloMx(Nem) biotope (all given in figure 37). SS.SSa.CMuSa.(AbraAirr) has been identified in the deeper areas to the east of Holy Island (D01 and D02). The sediment and the fauna are very similar but the abundance of Amphiura sp. is slightly lower than in the central parts of Lamlash Bay. The seabed environment appears to be very mixed in this region and none of the biotopes seems to be particularly dominant relative to others. Maerl is present, particularly on the shallower banks, but there is a big difference in the quality of the maerl with the maerl at LOC01 being relatively healthy whilst the maerl at LOC04 is difficult to detect at all. Table 8. Summary of the video and photographic analyses with the main substrata, fauna and biotopes (mixed sediments are muddy sandy gravel with shell material) in Outer Lamlash Bay (* LNC01 has been placed with Outer Lamlash Bay in the general description stage).

3.2.2.4 Southern entrance to Lamlash Bay

A shallow bank extends from the southern tip of Holy Island. This bank is dominated by maerl (P. calcareum) but brown and red seaweeds (macroalgae) are present in the shallowest sections obscuring the seabed making identification and quantification of maerl difficult (figure 38 and table 9) in some sections. In addition to maerl there are also patches of brittlestar beds. These patches are dominated by O. nigra have been classified as SS.SMx.CMx.OphMx. Some sections contain both maerl and brittlestars but as maerl beds are recognised as important habitats these areas have been classified as SS.SMP.Mrl.Pcal. The deeper area immediately west of the bank appears to be characterised by mixed sediment but potentially also muddy sands. However, as there are no ground-truthing data available from this section further survey work is required to assess this fully. Table 9. Summary of the video and photographic analyses with the main substrata, fauna and biotopes (mixed sediments are muddy sandy gravel with shell material) at the southern entrance to Lamlash Bay.

3.2.2.5 Scallops and other noteworthy species

The analysis of the photographic material resulted in identification of scallops (Pecten maximus and Aequipecten opercularis) and a few other noteworthy species (see appendix 09 with a summary in tables 10 and 11; and figure 39). M. rugosa is the most abundant taxon in the examples given in table 10 with the highest densities within the CR.LCR.BrAs.AmenCio biotope in 2008 and SS.SSa.CMuSa.(AbraAirr) in 2009. Only a few individuals of C. pagurus and Nephrops norvegicus were identified in the still photographs over the two years whilst Homarus gammarus was not identified at all. In 2008 scallops were found in all of the survey areas in Lamlash Bay (table 10 and appendix 09) in 2008 with P. maximus being, overall, the most common scallop taxon (in the still photography analysis), with the highest densities found in the SS.SMx.CMx.ClloMx(Nem), SS.SMP.Mrl.Pcal and CR.LCR.BrAs.AmenCio biotopes. The highest densities of A. opercularis in 2008 were found in the SS.SMx.CMx.ClloMx(Nem) biotope. The densities of P. maximus and A. opercularis appear to be very similar within the NTZ, with densities of both species being around 3 individuals/100 m2. Table 10.

In 2009 scallops were identified in the No Take Zone as well as within the SS.SMx.CMx.ClloMx(Nem) and SS.SMPMrl.Pcal biotopes (table 11). The 2009 densities of P. maximus are higher than those of A. opercularis within the NTZ; with densities of P. maximus of approximately 1.5 individuals/100 m2 whilst A. opercularis was not identified at all within this area (N.B. observing and identifying some species on camera footage is notoriously difficult (see below)).

The 2008 video analysis rarely allowed identification of the scallops to species level. This group was therefore recorded within the family Pectinidae (table 12). In 2008 the highest densities of scallops were found in the CR.LCR.BrAs.AmenCio and SS.SMP.Mrl.Pcal biotopes with overall densities of scallops being approximately 2 individuals per 100 m2. In 2009 the density values are slightly lower overall (c. 1 individual per 100 m2) with the highest densities found in SS.SMx.CMx and CR.LCR.BrAs.AmenCio biotopes (table 13 and appendix 9). The video density values are lower than the values seen in the still photography analysis, a result most likely linked to the fact that the identification (observe and count) of fauna is harder on the video compared to the photographs (some scallops were difficult to see even on still photographs; see figure 39). It should be noted that the biotope / habitat classification of individual photographs involves a subjective selection process and it is possible that some of the photographs or areas are classified incorrectly but the densities given in tables 10 to 13 give estimates of the densities of these taxa.

3.2.2.6 Maerl beds

As noted above, maerl beds (SS.SMP.Mrl.Pcal) were identified in the northern Lamlash Bay, in North Channel and in the Outer Lamlash Bay as well as around several regions of Holy Island (figure 40). These beds are typically found in the shallower areas but extend down to approximately ≤26 m. The maerl beds are found at NTZ01 - NTZ04, A01 - A03, D03, E01-E02, LNC02, LNC03, LNC09, LNC11, LOC01, LOC03 and LOC04 (see figure 40) but the vast majority of these beds are in a poor condition. The maerl beds at A01, A02 and LOC01 are the healthiest populations with the largest proportion (5-10 %) of live maerl. LOC04 is an area with some maerl in particularly poor health with very few scattered individuals present (all dead). In fact, in many cases it was difficult to identify the maerl without zooming in on the images and maerl was not detected during the video analysis, illustrating the need for both still photography and video footage to ensure recording large-scale and small-scale features. LOC04 can therefore not be classified as a maerl bed and this location is best described as an area of scattered maerl. Other regions with maerl are mixed with macroalgae (covering the seabed) making identification of the maerl challenging. The assessments of the condition of these beds are therefore more difficult and uncertain to some extent.

3.2.2.7 Brittlestar beds

Patches of seabed with brittlestars (CR.LCR.BrAs.AmenCio.Bri) were observed at several locations (E01, E02, LNC08, LNC10, LOC03, and LSC01) of the Lamlash Bay survey (figures 38 and 41). The dominant taxon was O. nigra. The other brittlestar taxon Ophiothrix fragilis, which was often associated with O. nigra elsewhere, was not seen in these samples.

3.3 Sediment samples A total of 10 Day grab samples were collected within the NTZ in Lamlash Bay (table 14 and appendix 03). A sub-sample was collected for Particle Size Analysis and the remaining sample was retained for further macrofaunal processing and analysis. Table 14.

3.3.1 Particle Size Analysis

The results from the particle size analysis from the Day grab samples are given in appendix 04 with a summary in table 15 (mud, sand and gravel refer to all size fractions within each category). The results illustrate that all the sites are dominated by “sand” with at least a proportion of mud being present at all the locations. The highest percentage of mud (>10 %) is found at NTZ02, NTZ03 and NTZ04. Gravel is also present but not at all the locations. NTZ08 and NTZ10 have the highest percentage of gravel but smaller percentage is also present at NTZ07 and NTZ09 (table 15). Overall, however, and the most important aspect of these results is that sand represents more than 80 % of the sediment at all but one of the 10 sites (see table 15). These 9 locations can therefore classified as “Sand” (greater than 80% sand; see appendix 05) according to the modified Folk triangle (Folk, 1954) sediment classification system as adapted by the Joint Nature Conservation Committee (JNCC; see Connor et al., 2004) with NTZ08 also dominated by sand (77 %). In terms of the sediment present, 9 sites could therefore also classify as SS.SSA (sublittoral sediment, sublittoral sands and muddy sands) but as both the sediment type and fauna have to be considered when classifying a site as a particular biotope according to the JNCC Marine Nature Conservation Review Biotope Classification (Connor et al., 2004) system, some of the sites are classified as different biotopes (see below). Table 15. Total number of individuals of the most abundant taxa/species present in the 2008 Lamlash Bay grab samples.

The “sand” size class can be further divided according to the sediment size classification based on the Wentworth scale (see e.g. Leeder, 1982). Further analysis of the data shows that within the ‘sand’ category, all the sites are dominated by fine or very fine sand (figure 42 and table 16). Relatively higher proportions of medium and coarse sand, as well as the gravel fractions noted above, are found at three locations (NTZ07, NTZ08 and NTZ10).

3.3.2 Macrofaunal distributions

The macrofaunal analysis revealed a total of 2726 individuals and 160 taxa (appendix 06) in the Lamlash Bay Day grab samples (including meiofauna and epi-fauna). Overall the macrofauna is dominated by Mollusca (45.0%) and Annelida (30.7%), representing 75.7% of the identified fauna. The Echinodermata and Crustacea comprise 16.0% and 6.3% of the macrofauna respectively while the Nemertea represent 1.0% and the remaining groups (Cnidaria, Sipuncula and Ascidiacea) represent 0.08% of the fauna. One individual of Gobiidae sp. was also found in one of the Day grab samples.

50

3.3.2.1 Abundance

The abundance of the identified macrofauna collected in the NTZ in Lamlash Bay Day grab survey is given in appendix 06 with some examples of the most abundant species / taxa given in table 17. As with the overall data, Mollusca and Annelida dominated the macrofaunal community. The most abundant taxon is Mysella bidentata, followed by Amphiura filiformis, Prionospio fallax and Thyasira flexuosa. M. bidentata is typically found in muddy sand and fine gravel (sometimes in burrows of sipunculids or associated with ophiuroids) while the suspension feeder A. filiformis is found in muddy sand (Hayward and Ryland, 1991). T. flexuosa is typically found in sandy muds (Tebble, 1966). The ecology of the dominant fauna therefore seems to correlate with the dominant sediment types in Lamlash Bay (silty sand) and although little information is available for the ecology of P. fallax, the current data suggest that P. fallax is also found in muddy sand (most abundant in locations with the highest percentage of silty sand: see appendix 06).

3.3.2.2 Diversity

The results from the species diversity analysis are given in table 18. The total number of individuals present at the 10 Lamlash Bay Day grab samples range from 133 individuals per sample to 474 individuals per sample whilst the total number of taxa range from 37 to 64 among the samples, indicating that there are some differences between the different locations. The species diversity (Shannon-Wiener diversity index) overall is low (to medium) with diversity being highest at locations NTZ 05 to NTZ 10. The equitability (J) results suggest a similar pattern where locations NTZ 01 to NTZ 04 have low equitability, indicating higher dominance by a small number of different species, while the results from the other locations (NTZ 05 to NTZ 10) indicate a more equal distribution between species. Table 18.

3.3.2.3 Macrofaunal composition

The results from the cluster analysis and ordination of all the Lamlash Bay infaunal data are given in figures 43 and 44. The cluster analysis group locations NTZ07, NTZ08 and NTZ10 in one cluster whilst the remaining locations are grouped together in a separate cluster (figure 43), results that appear to closely follow the sediment distributions described above (section 3.3.1) where locations NTZ07, NTZ08 and NTZ10 are found in the slightly coarser sediment while the remaining samples are found in ‘fine’ sediments.

52

Figure 43. Cluster analysis of the 2008 Lamlash Bay macrofaunal Day grab data.

The ordination analysis support the cluster analysis results (figure 44) grouping NTZ07, NTZ08 and NTZ10 together (coarser sediment group) whilst the remaining seven locations are found in the ‘fine’ sediments. The ordination furthermore reveals a very low level of stress (0.01) giving “an excellent representation with no prospect of misinterpretation” (Clarke and Warwick, 1994). The data were analysed using a number of different variables but the results were unchanged further strengthening the results given here. Figure 44. Ordination analysis of the 2008 Lamlash Bay macrofaunal Day grab data (all 10 locations).

53

The ordination results given in figure 44 illustrate the seven ‘fine’ sediment locations grouped very closely together. To assess any potential patterns further a second MDS plot of the remaining seven locations was produced (figure 45). This second ordination analysis largely supports the results in the cluster analysis, grouping NTZ05, NTZ06 and NTZ09 in one group and NTZ01 to NTZ04 together in the other, suggesting some small differences between the two faunal communities. The level of stress of the ordination is slightly higher (0.06) in this analysis but still “corresponds to a good ordination with no real prospect of a misleading interpretation” (Clarke and Warwick, 1994). Figure 45. Further ordination analysis of the 2008 Lamlash Bay macrofaunal Day grab data (the 7 locations grouped).

To assess these groups further, a SIMPER analysis of the 2008 macrofaunal Day grab samples in Lamlash Bay was carried out to assess the most dominant species in the ‘coarse’ (NTZ07, NTZ08 and NTZ10) and ‘fine’ sediment groups as identified in the cluster and ordination analyses (table 19).

Many of the dominant fauna in the ‘fine’ sediment group are typically found in muddy sands (and sandy muds) typified by M. bidentata, A. filiformis and T. flexuosa (see above; Tebble, 1966 and Hayward and Ryland, 1995). The relative contribution of M. bidentata to this community is very high compared to any of the other species. The most characterising fauna in the ‘coarse’ sediment cluster are typically found on substrata of a mixed character, preferences supporting the overall clustering. Dosinia lupinus is a suspension feeder found on sandy mud, sand and shell gravel. Mediomastus fragilis is a sub-surface deposit feeder found on muddy gravel, sandy mud, muddy sand and mud. Lumbrineris gracilis is a predator / omnivore found on gravel / shingle, muddy sand and mud.

A second SIMPER analysis was carried out assessing the potential differences between the two groups in the ‘fine’ sediment clusters (‘fine 1’ consists of NTZ01 to NTZ04 while ‘fine 2’ consists of NTZ05, NTZ06 and NTZ09) and although there are differences in the communities (table 20), the main difference seem to be the relative contribution of the taxa present as the four most dominant taxa are present in both groups. The results suggest that the relative importance of the number of individuals of both M. bidentata and A. filiformis are the most important differences between the two groups, suggesting that there are subtle differences in the habitats forming these two groups.

3.3.3 Comparisons between macrofaunal trends and the sediment data

The sediment variables (sediment retained on the different sieve sizes used) were used to assess any correlations between these data and the cluster analysis results (figure 43) using the Spearman rank correlation coefficient (r

s) and the results are given in table 21.

The results show that the highest correlation is found between the faunal distributions and sediment retained on sieve size 1.0 (very coarse sand) with a positive correlation of 0.813 but other correlations are also high with sieve sizes 0.063 (0.777), 0.5 (0.751) and 0.25 (0.612) of particular note (these sieve sizes refer to very fine sand, coarse sand and fine sand respectively). Various combinations of sediment sizes were also tested and the highest correlation was found with a combination of 8.0, 4.0, 1.0 and 0.063 sieve sizes which resulted in a Spearman rank correlation coefficient (r

s) of 0.85. Overall therefore the results

indicate that the sediment size has a strong positive correlation with the faunal distributions in the Lamlash Bay Day grab samples. Table 21. Results from the Spearman rank correlation coefficient analysis comparing the faunal data with the sediment data collected at Lamlash Bay 2008.

3.3.4 Biotope classification of the 2008 Lamlash Bay Day grab samples

The combination of the sediment distribution, depth and the macrofauna present has resulted in a biotope classification for the Lamlash Bay Day grab samples (table 22). As noted previously, the dominant sediment type throughout the 10 samples was sand (>80 % in all but one of the samples) suggesting that all the locations should be classified within the ‘main habitat’ SS.SSa (sublittoral sands and muddy sands; see above and Connor et al., 2004). The sediment samples clustered as ‘fine’ in the cluster and ordination analyses (NTZ01 to NTZ06 and NTZ09) could be (based on the depth and sediment size data) classified as biotope complex SS.SSa.CMuSa (circalittoral muddy sand) as the mud content is >5% at all seven locations (see Connor et al., 2004). The dominant fauna in these seven samples (described above) also support this classification but neither of the two biotopes at level 5 in the hierarchy (SS.SSa.CMuSa.AalbNuc and SS.SSa.CMuSa.AbraAirr) seems to fit the fauna identified in Lamlash Bay perfectly. The strongest agreement between many of the taxa present and those described by Connor et al. (2004) are those in the SS.SSa.CMuSa.AalbNuc biotope. This biotope is therefore tentatively selected as the biotope for the locations in the ‘fine’ sediment cluster group (NTZ01 to NTZ06 and NTZ09). The samples clustered as ‘coarse’ (NTZ07, NTZ08 and NTZ10) were classified as muddy gravely sand in the Particle Size Analysis (see PSA section above) and the fauna was dominated by different taxa compared to those seen in the ‘fine’ cluster group. Considering the sediment content and the fauna present, these locations have been classified as biotope complex SS.SMx.CMx. A more detailed assessment of the fauna in the ‘coarse’ cluster suggests that these locations could be classified as SS.SMx.CMx.MysThyMx (level 5 of the biotope classification hierarchy). This particular biotope is found in moderately exposed or sheltered areas with common infaunal polychaetes species including P. fallax and Lumbrineris gracilis as well as amphipods such as Ampelisca spp. together with the brittlestar Amphiura filiformis. However, this biotope is characterised by the bivalves Thyasira spp. (often T. flexuosa) and M. bidentata, and although these taxa are present in the samples, they are not very common. The classification of the locations NTZ07, NTZ08 and NTZ10 can therefore only tentatively be classified as SS.SMx.CMx.MysThyMx at this stage. It should be noted that maerl (P. calcareum), has been recorded (in shallow water) as part of this biotope but at low abundances (Connor et al., 2004), an observation that seems to be valid in the current study (see other sections of this report).

3.4 The seabed environment in Lamlash Bay The analysis of the sidescan sonar mosaic and bathymetry together with the ground-truthing using the photography and video records as well as the incorporation of these data into the ArcView GIS allowed for a more detailed assessment of the habitats in Lamlash Bay. The interpretation of the sidescan sonar mosaic (figures 6 and 7) together with the ground-truthing (see examples of photographs above) reveals a complex, patchy and heterogeneous seabed environment difficult to delineate and summarise in a single image. The results are therefore displayed in six images (figures 46 to 51) with the underlying aim not to overly extrapolate the data sets available. Figure 46 illustrates the sidescan sonar imagery together with the bathymetry across the study area while figure 48 focuses on the NTZ. The results not only show a very good match between the features seen but also positions of the shallow banks and regions not surveyed in 2008. Figures 47, 49 and 50 illustrate the distribution of biotope complexes and biotopes identified in the Lamlash Bay study. The maerl biotopes (SS.SMP.Mrl.Pcal) are illustrated in red and these are found in Outer Lamlash Bay, in the North Channel, at the southern entrance to Lamlash Bay and in northern Lamlash Bay with extensive beds within the NTZ. Note, however, that one location (LOC04) north of the entrance to North Channel, is described as scattered maerl rather than a maerl bed and it is currently unclear whether the maerl found here is more extensive or not. The purple polygons can be exemplified by Deacon Rock (figure 47) in the centre of the bay. Some coarse material is found around this outcrop but the substrata change gradually in several directions. The direction of the sidescan sonar survey lines seems to affect the quality of the imagery in this region suggesting a need for careful planning for future sidescan sonar monitoring surveys. Other rocky outcrops (CR.LCR.BsAs.AmenCio) are found in the study area, some of which are found within the brown polygons (in figures 47 and 49), which consist of mixed coarse sediments (SS.SMx.CMx) of muddy, sandy gravel. Most of the rocky outcrops are found in northern Lamlash Bay, but also in the shallow waters across the Bay. The surrounding areas in figures 47 and 50 consist of muddy sand and sandy mud but some of these features need additional ground-truthing (e.g. sediment sampling) to increase the levels of confidence in the data. Some of the data have been extrapolated to create these biotope maps using the confidence model described above. Figures 49 to 51 illustrate the still photography camera transects across the sidescan sonar imagery with each coloured circle signifying one photograph. The colour of the circles signify a biotope (figures 49 and 50) or a substrata type (figure 51) and the changes can be seen along each photographic transect. Overall the correlations between the boundaries of sediment / substrata type and biotope / habitat type are very good throughout the survey area but some of the subtle changes in the faunal distributions are not always apparent in the patterns seen in the substrata. This is best exemplified in the sector in the south-southwest where there is no apparent evidence of faunal change across an area that changes from muddy sand to sandy mud (figures 47 and 50). Additional sediment sampling is required to assess the current infaunal compositions within the bay and allow monitoring of any future potential changes in the infaunal composition in these areas. Furthermore, areas classified as muddy sand biotopes have in many places been classified as sandy mud in the sediment classification and the other way around. The difference in sandy mud and muddy sand is at times very difficult to discern on seabed photographs and video footage but with the presence of burrows and other features the current classification using the photographs is deemed appropriate. Therefore these discrepancies are more likely linked to the biotope classification system which is based on both epi- and infaunal data potentially explaining some of the discrepancies between the two results.

4 DISCUSSION

4.1 Survey methodology An integrated approach using a range of survey techniques to study an area of seabed has been shown to be successful in many studies. The use of sidescan sonar and photography together with traditional survey techniques (e.g. grab sampling and trawling) have become more commonly used in recent years (e.g. Bett and Masson, 1998; Brown et al., 2002; Axelsson, 2003; Masson et al., 2003; Brown et al., 2004a, b; Stevens and Connolly, 2005; Axelsson et al., 2006). The use of video and still photography in surveys has been shown to be cost-effective with large areas being covered in a relatively short time (Brown et al., 2004a; Stevens and Connolly, 2005) with a number of studies concluding that video and still photography are appropriate for the assessment of the presence and extent of biotopes (Sanderson and Holt, 2001; Service and Golding, 2001) as well as ground-truthing of acoustic images (Brown et al., 2002; Brown et al., 2004a, b). However, it is acknowledged that there is some loss in the taxonomic resolution when using photography rather than biological sampling techniques (e.g. Stevens and Connolly, 2005) and some video records are not of a sufficient quality to allow biotope classifications to be carried out. Still photography should be carried out simultaneously to supply meaningful images (Hiscock and Seeley, 2006). Even though these suggestions may reflect some of the difficulties associated with the biotope classification system, combining digital video and still photography with sediment sampling in surveys appears to have advantages over a single system and allows an overall higher quality assessment to be carried out. Most recently new techniques have been developed to allow seabed discrimination using the acoustic signals from sidescan sonar and multi-beam systems with the potential advantages of being relatively low cost, rapid and allowing coverage of large areas (Preston, 2006a, b). As some techniques and methods used in habitat mapping and seabed discrimination are relatively new, problems are still likely to occur during at least some part of a project involving these methods. The analysis of the sidescan sonar together with the ground-truthing using the drop-down camera system and sediment sampling has proven to be a very successful method for studying the large-scale features in Lamlash Bay but also to investigate the finer biological and sedimentary features within the study area. Overall the sediment distributions and the positions of most of the rocky areas are broadly consistent with those previously reported (see Duncan, 2003) although the current study is more extensive than previous work. Undoubtedly, there are some aspects that could be improved with further work, particularly with more extensive sediment sampling to obtain additional survey coverage and understanding of the infaunal habitats and species in the area. However, the current survey has provided a broad overview of the habitats within the area and can be considered successful in achieving the original aims.

4.2 Survey limitations

4.2.1 Survey extent

The extent of the survey coverage in 2008 was limited as a result of the draught of the survey vessel used, excluding the seabed environment shallower than 10 m. The additional survey work in 2009 resulted in a more extensive coverage, particularly with regards to the acoustic aspect of the work. However, the 2009 ground-truthing coverage had to be limited according to available funds, which therefore restricted the time available to complete survey work in all areas of interest. It would be useful to acquire additional sediment samples as well as further drop-down camera ground-truthing data to allow a more complete description of the biotopes present, assess the densities of commercial and other noteworthy species as well as enable future monitoring of any spill-over effects of the NTZ. In particular, it would be

65

very useful to acquire additional drop-down camera data to allow a higher confidence in (and better coverage of) the biotope classification in, for example, the southern region of the NTZ and at the southern entrance to Lamlash Bay. The current ground-truth coverage limits the interpretation and extrapolation of the data (see section 4.3 (limitations) and figures 47, 49 and 50), largely as a result of the complexity of the seabed environment.

4.2.2 Discrepancies between the sidescan sonar and photographic survey results

The interpretation of the sidescan sonar and the subsequent ground-truthing resulted in some discrepancies in the boundaries between different habitats / biotopes. This discrepancy has a number of possible explanations including: 1) positioning of camera frame relative to navigation data; 2) boundaries of biotope / habitat classifications; and 3) depth of acoustic signal penetration. 1) Positioning of camera frame relative to navigation data During the survey operations, a lay-back error was calculated for the camera frame position in relation to the vessel; however, as this was based on the position of the A-frame from which the camera frame was deployed and did not allow for movements of the camera on seabed, slight inaccuracies in positions of the camera deployments are possible (maximum inaccuracies are estimated to be 5 m). 2) Biotope / habitat classifications The exact positions of the boundaries between different biotopes were often difficult to determine as many boundaries were transitional in nature. The change in sediment tended to be gradual along transects and the determination of the boundary between two types became difficult. Some of the boundaries identified from the camera deployments did therefore not match exactly with those seen on the sidescan sonar imagery but overall the results were good. 3) The depth of the acoustic signal It has been shown that some sidescan sonar frequencies (e.g. 30 kHz) penetrate into the sediment and therefore return volume backscatter rather than a backscatter signal from the uppermost sediment surface (Blondel and Murton, 1997; Axelsson, 2003; Masson et al., 2003). The lower frequencies penetrate the most (Blondel and Murton, 1997) and at 30 kHz the signal could penetrate tens of centimetres (Masson et al., 2003). It is therefore possible that in certain sediments, acoustic signals at 100 kHz could penetrate the sediment to some degree and therefore generate results different to those seen on seabed photographs. However, as 410 kHz was used in the Lamlash Bay survey, signal penetration is unlikely to explain any of the discrepancies seen in this study. 4.3 Confidence assessment In this study attempts have been made to minimise interpolation of the data as much as possible but as with many similar studies ground-truth coverage is not as extensive as perhaps desired. In order to illustrate the quality and interpretation and interpolation of the data confidence ratings have been given to the figures. The confidence in the level of certainty of the interpretation of the seabed environment and biotope maps (e.g. figures 47 and 50) at point source (i.e. a photograph) is estimated at 90-100 % accurate (level 1), while confidence level 2 (areas with the same backscatter surrounding a photograph) is estimated to be 80 % accurate and confidence level 3 (areas with the same levels of backscatter but some distance away (c. 50 - 100 m) from the photographs) is estimated to be approximately 50-60 % accurate (e.g. southern NTZ). The reasoning behind the relatively low confidence rating for level 3 is best illustrated by the ground-truthing of the southern and central Lamlash Bay (see figure 47 and 50), where some areas of the seabed appear similar on the sidescan sonar records but are shown to be different by the photographic ground-truthing data.

66

Video and still photography have been shown to be appropriate for the assessment of the presence and extent of biotopes, but the quality of the data interpretation and biotope records from video tapes relies on the identification skills of the person scoring the tapes (Holt et al., 2001). The classification of biotopes is also somewhat subjective and not all seabed environments ‘fit’ the biotope classification scheme resulting in some biotopes being classified to ‘best fit’ the communities present (Holt et al., 2001). Some studies therefore develop a specific habitat or biotope classification scheme (see for example Brown et al., 2004a) for that survey but long-term perhaps the biotope classification system by Connor et al. (2004) will be developed further and therefore more widely used. However, obtaining high level of confidence in the data still requires an experienced marine biologist, ideally with local knowledge, although a quality assurance programme including re-assessments of the tapes can recover any lost data or mistakes in the classifications (Holt et al., 2001).

4.4 Comparisons with previous studies As mentioned above, there are no records for Lamlash Bay within the Marine Nature Conservation review (MNCR) database (now Marine Recorder) prior to 2003 (Duncan, 2003; COAST, 2005). Furthermore, only a couple of studies appear to have been carried out since then (Duncan, 2003; Kamenos et al., 2004), both of which describe Lamlash Bay as primarily composed of soft substrata apart from a number of rocky reefs (e.g. Deacon Rock and areas along the North Channel). Although direct comparisons are difficult as a result of the lack of exact positions of many features in previous studies, the ground-truthing of the seabed environment in 2008 and 2009 largely agrees with the previous studies as well as the records on the admiralty charts, with mixed sediments (muddy, sand and gravel) in the North Channel and muddy sand in the central and southern regions of Lamlash Bay. The admiralty charts furthermore illustrate increased mud content along the south-western section of Lamlash Bay, a feature also seen in the 2008 survey. In 2003 the main biological features of note in Lamlash Bay were maerl and sea grass (eelgrass) beds as well as sublittoral rocky reefs with kelp (Duncan, 2003). In 2008 and 2009, maerl was found to be extensive in Lamlash Bay but the sea grass beds were not identified at all. This could be explained by the fact that survey work in the north-western region, where the seagrass has previously been found, was obstructed by moorings. Additional survey work may therefore be required to assess this feature further. Rocky reefs were also identified in both the 2008 and 2009 Lamlash Bay surveys.

4.4.1 Lamlash Bay rocky reefs

A number of rocky reefs (mainly boulder, cobble debris areas) were found in the 2008 survey, including the rocky outcrop known as Deacon Rock. Additional reef features were found during the 2009 survey work in the shallow waters along the northern coastline, including Gurnard Bay (Holy Isle) and the northern coast near Clauchlands Point, and around Holy Island.

Deacon Rock has been described as a submerged reef rising from 17 m up a steep slope of sea squirt covered boulders to a sugar kelp (Laminaria saccharina) and mixed red algae crowned apex at 10 m. The 2008 study did collect acoustic data across Deacon Rock and camera transects did record the sea squirt covered boulders around it but the kelp covered apex was not surveyed using the drop-down camera (too shallow for the vessel used), although kelp debris was found on the seabed in the surrounding areas. Other flora and fauna found on and around the boulders included red algae, short and long hydroid turf, C. lloydii, T. communis, Ophiura sp. and sponges (Suberites sp.) as well as O. nigra brittlestar beds on some sections of the outcrop.

67

A number of bedrock ledges near the fish farm cages are also apparently present (Duncan, 2003; Seasearch, 2003). These rocks are reportedly covered in black silt with relatively sparse fauna present but because of the presence of the fish cages it was not possible to cover these areas in the 2008 or 2009 surveys.

4.4.2 Lamlash Bay maerl beds

Maerl is the collective name for several species of calcified red seaweed with three species of maerl occurring in the UK, P. calcareum, Lithothamnion glaciale and Lithothamnion corallioides. Maerl grows as unattached nodules on the seabed and under favourable conditions can form extensive beds (UKBAP, 2008). Maerl is slow growing but over long periods its dead calcareous skeleton can accumulate into deep deposits (an important habitat in its own right), overlain by a thin layer of pink living maerl. Maerl beds typically develop on coarse sediments and in clean water where there is some tidal flow, such as in the narrows and rapids of sea lochs, or in open sea where wave action is sufficient to remove fine sediments (Hall-Spencer and Moore, 2000; Kamenos et al., 2004; UKBAP, 2008). Although maerl beds cover a very small area of UK waters, all of the beds studied to date have been found to harbour disproportionately high diversity and abundance of associated organisms in comparison with surrounding biotopes; some of these species are confined to maerl habitat or rarely found elsewhere (Nunn, 1992; Hall-Spencer and Moore, 2000). In the Lamlash Bay surveys only P. calcareum was identified with certainty, with occurrences in the northern and Outer Lamlash Bay areas as well at the southern entrance to Lamlash Bay (area E). Maerl was not identified in the central regions of Lamlash Bay. Duncan (2003) reported the remains of a deep maerl bed (Phymatolithon sp.) in the North Channel entrance. This maerl bed is still evident in 2008 but as with the majority of the maerl beds found in 2008 and 2009, these beds are in relatively poor health. The healthiest maerl bed was found in the northern region of the Outer Lamlash Bay area (camera transects LOC01, A01 and A02) with up to 5-10% live maerl whilst only scattered maerl in poor condition was found at the northern edge of the North Channel entrance (LOC04). The maerl beds along the northern border of Lamlash Bay and along the North Channel were generally found to have approximately 1 % of live maerl, at least in sections, but the healthy beds described by Kamenos et al. (2004) south of Clauchlands Point (up to 85-95 % live maerl) were not identified in either of the 2008 or 2009 surveys despite the increased survey coverage in 2009 (including the shallower depths on the banks surrounding North Channel in particular). The deepest record of maerl in the Lamlash Bay 2008 survey was at approximately 26 m. These results are in line with those reported in a study describing maerl being found down to about 30 m depth in European waters (Hall-Spencer and Moore, 2000).

4.4.3 Other fauna and flora in Lamlash Bay

Apart from the maerl beds mentioned above, no other rare species (see Sanderson, 1996; Vincent et al., 2004) were identified in the Lamlash Bay surveys; although it is possible that some remain undetected as a result of the taxonomic limitations of using camera equipment (see Stevens and Connolly, 2005). As a general rule sponges were rarely recorded in the Lamlash Bay study but comparisons with Duncan (2003) and Seasearch (2003) are difficult as sponges were equally rare in these studies. The most common sponges group in the Lamlash Bay study were the encrusting sponges but individuals of Amphilectus fucorum and Suberites sp. were also recorded, all of which were found in the rocky areas in the northern and Outer Lamlash Bay areas.

68

As in the previous studies (Duncan, 2003; Seasearch, 2003) the Cnidaria was dominated by small and tall hydroid turf (including Nemertesia spp.) in rocky areas, as well as C. lloydii in soft sediment areas. As in these earlier studies M. senile and Alcyonium digitatum were also recorded. In Crustacea the squat lobster M. rugosa was by far the most common taxon in 2008 with juvenile Galathea sp. being relatively abundant in the grab samples. Hermit crabs were recorded but some were most likely undetected and thus might be more common than recorded in this study. Squat lobsters were recorded in earlier studies but not to species level and hermit crabs were found to be widespread (see Duncan, 2003). Edible crab (C. pagurus) and lobsters (H. gammarus) were reportedly present at a number of sites in 2003 (7 and 5 locations respectively) but in 2008 and 2009 edible crabs were rare and lobsters were not recorded at all. The dive surveys in 2003 are more likely to detect and record these crustaceans compared to drop-down camera deployments which may at least partly explain this difference. T. communis was by far the most common Mollusca taxon in the 2008 and 2009 camera footage, a taxon only mentioned in passing in the 2003 surveys. Scallops, on the other hand, were widely distributed in the 2003 surveys. Of particular note in 2003 was a large number of juveniles ‘in the middle of the north channel’, the return of scallops to Deacon Rock as well as the complete absence of scallops near the fish cages (south-southwest) (Duncan, 2003; Seasearch, 2003). Scallops are also widely distributed in the 2008 and 2009 Lamlash Bay surveys but only at densities of approximately 3 individuals/100m2 (there are no density values for the 2003 surveys). The dominant taxa in the Day grab samples are given in table 17 but as there are no other available data, comparisons are not possible. Among the Echinodermata brittlestars were the most abundant taxa in both 2008 and 2009 with Ophiura sp. and Amphiura sp. being the most abundant taxa overall. Other recorded echinoderms were O. nigra, A. bifida and E. esculentus. References were made to brittlestars and featherstars in the 2003 surveys (Duncan, 2003; Seasearch, 2003) but these taxa were not identified to species level. Among the infaunal samples (the 2008 Day grab samples) other echinoderms were present but no comparable data are available from previous studies. A large number of fish species (19 in total) were recorded in the 2003 surveys with flatfish being the most common (Duncan, 2003). Pollock was also present together with several different species of gobies and wrasse. In 2008 and 2009 only a few fish species were recorded, presumably as a result of this group being highly mobile and avoiding the camera during deployments. A few commercial species including Haddock (Melanogrammus aeglefinus) and some flatfish were identified but the most common fish were gobies and dragonets, species also identified in 2003.

4.4.4 Biotope distribution in Lamlash Bay

There are no biotope classification records for Lamlash Bay prior to the 2008 Lamlash Bay survey. A general overview of the number of biotope complexes present within the Irish Sea region has been produced as part of the Irish Sea Pilot (Vincent et al., 2004). These results suggest approximately four biotope complexes in the Lamlash Bay area (results based on data collation and some ground-truthing) but there is a general lack of detailed information for the Clyde region outside the sea lochs. A habitat mapping study was initiated by the Scottish Sustainable Marine Environment Initiative Firth of Clyde Pilot Project but the final report has not been completed as a result of a number of complications together with the lack of ground-truthing of acoustic data (SSMEI,

69

2007). However, a predictive model of the seabed habitats present within the Clyde Sea region was produced indicating a total of five seabed habitat types within Lamlash Bay and six seabed habitat types in the entire Lamlash Bay region (Lamlash Bay and the Outer Lamlash Bay areas). These results agree with those seen in the 2008 Lamlash Bay survey (see figure 47), however, three additional biotopes were identified in the shallow regions (<10 m) in the bay in the 2009 survey and additional biotopes may be present in regions not covered by the 2008 and 2009 ground-truthing surveys.

4.4.5 Evidence of fishing activity

Indications of fishing activity were evident in October 2008 when fishing vessels were observed moving into Lamlash Bay immediately after the completion of the 2008 survey operations. In addition, scallop dredging marks were identified in the photographic and sidescan sonar imagery close to Rocky Bank in central Lamlash Bay (see target 3 above). However, there was no evidence of any dredging marks in the 2009 data. Continued monitoring by sidescan sonar could potentially be used to assess any future dredging, although bearing in mind that such marks will gradually be removed by physical processes and the likely duration of persistence is not known at this location. 4.5 Recommendations for future monitoring at Lamlash Bay The primary issue fundamental to any future monitoring will be the enforcement of the fishing ban to ensure there is no fishing activity within the NTZ. Without enforcement there might be a need for additional monitoring survey work to assess any changes to the seabed environment following such activities. Assuming there is no fishing activity within the NTZ the recommendations below are based on Special Areas of Conservation (SAC) monitoring attributes (Davies et al., 2001). Lamlash Bay is not an SAC but the attributes and targets proposed for monitoring are relevant here (table 23). Table 23. Lamlash Bay monitoring attributes.

Attribute Target Sediment character Monitor any changes in composition of sediment types

across the bay. Distribution of biotopes Monitor any changes in the distribution of biotopes.

Extent of sub-feature Monitor any changes in extent of biotopes. Monitor the extent of maerl and sea grass beds Monitor the quality of maerl and sea grass beds Monitor any changes in other characteristic species

Species composition Monitor any changes in biotope quality as a result of addition or removal of notable species

Species population measures - population structure of a species - presence or abundance of specified species

Monitor species abundance and composition of biotopes Monitor age/size class structure Monitor presence / abundance of characteristic species

4.5.1 Requirement for additional survey effort

70

There are several habitats and species within Lamlash Bay requiring future monitoring measures. The 2008 and 2009 Lamlash Bay surveys collected considerable amounts of baseline data (as outlined above) but additional baseline data are required to allow future monitoring of all the habitats and species present in Lamlash Bay. The Day grab sediment sampling programme should be extended to the areas surrounding the NTZ to allow monitoring of the habitats and species present (e.g. changes in species composition and animal sizes as well as potential spill-over effects). Scuba-diving surveys are also recommended to collect additional qualitative (transect surveys) and quantitative data (using quadrats) on the sea grass beds (e.g. shoot count and sea grass length measurements) to allow future recovery assessment studies.

4.5.2 Future monitoring in Lamlash Bay

4.5.2.1 Sediment character

The character of the seabed environment might change as a result of the classification of the NTZ. The sediment composition could be assessed using the same methodology as in this survey to allow continuity of analysis and monitoring. Camera deployments and sediment sampling using a 0.1 m2 stainless steel Day grab should be carried out at 2 year intervals.

4.5.2.2 Distribution of biotopes

This attribute could be assessed by monitoring the spatial extent of the different biotopes within Lamlash Bay simply by monitoring the identity of the biotopes at the existing sampling stations. Camera deployments and sampling of infauna and epifauna using a 0.1 m2 stainless steel Day grab should be carried out every 2 years. Monitoring of the presence and abundance of characteristic species for each biotope should be carried out and it would be useful to extend the grabbing survey into the areas surrounding the NTZ. It would also be useful for future monitoring (every 6 years) to continue to identify biotope boundaries using broad scale techniques (e.g. sidescan sonar) so that at least very conspicuous changes will become apparent.

4.5.2.3 Extent of sub-features

The extent of biologically important biotopes such as the sea grass beds is unknown. Investigations into the extent and distribution of this feature should be carried out. The use of drop-down video together with scuba-diving transects and quadrat sampling (for repeatability) during favourable weather conditions is recommended. Continued monitoring of the extent of the important sub-features (maerl in particular) should be carried out using drop-down camera and Day grab sediment sampling at 2 year intervals with acoustic (sidescan sonar) monitoring carried out at 6 year intervals.

4.5.2.4 Species composition and population measures

Repeat drop-down camera and sediment sampling surveys should be carried out at 2 year intervals to assess any changes in the main habitats and species present in Lamlash Bay. The quality and extent of the maerl beds as well as the size, quality and extent of other habitats (e.g. size and extent of brittlestar beds and hydroid turf, the latter potentially associated with scallop recovery) could be assessed using the current methodology. Additional scuba-diving surveys of the sea grass beds could also be carried out at 2 year intervals to assess any changes to the sea grass beds and the associated species.

71

Changes to scallop populations and other noteworthy taxa (e.g. commercial fish and shellfish species as well as invertebrates forming part of the diet of commercial species) could also be monitored using the methodology described in this study. Both P. maximus and A. opercularis spawn twice a year (environmental conditions allowing) with P. maximus being sexually mature after two years and A. opercularis after one year (Barnes, 2009a; Marshall and Wilson, 2009). A three year old P. maximus can produce 15-21 million oocytes (no data for A. opercularis) with a high dispersal potential (10 km or more), allowing any changes in population sizes to occur within one or two years. Other commercial species noted above, such as C. pagurus, N. norvegicus and H. gammarus, take 6-10, 3-4 and 6-10 years respectively to reach sexual maturity (Tuck et al., 2000; Barnes, 2009b; Neal and Wilson, 2009). Consequently, as well as the absolute abundance of organisms, the reproductive capacity of these populations is important in considering the recovery times of such species. Monitoring by means of camera deployments and sediment sampling using a 0.1 m2 stainless steel Day grab should therefore be carried out at 2 year intervals to allow continuous and regular monitoring of any changes to the faunal populations and species composition. With the sediment sampling effort extended to include areas outside the NTZ, direct comparisons (e.g. abundance and spill-over effects) between the changes of faunal populations within the NTZ with those outside the area will be possible.

5 CONCLUSIONS

The habitat mapping surveys in Lamlash Bay in 2008 and 2009 were a success in terms of collecting high quality data including sidescan sonar and echosounder data together with high quality ground-truthing still photographs and video footage. The sediment sampling programme was also deemed a success but additional sampling outside the NTZ is required to allow direct comparisons (e.g. changes in species composition, changes in abundance and spill-over effects) between the two areas in future monitoring. The ground-truthing of the sidescan sonar data revealed a heterogeneous and complicated seabed environment dominated by sand but areas of mixed sediment, bedrock as well as areas of boulder / cobble debris are also present. The analysis of the photographic material (stills photographs and video) revealed a total of nine biotopes within Lamlash Bay to date: SS.SMx.CMx.ClloMx(Nem), SS.SMX.CMx.OphMx, SS.SMu.CSaMu.(AfilMysAnit), SS.SSa.CMuSa.(AbraAirr), SS.SMP.KSwSS.LsacR.CbPb, SS.SMP.KSwSS.LsacR.Sa, CR.LCR.BrAs.AmenCio, CR.LCR.BrAs.AmenCio.Bri and SS.SMP.Mrl.Pcal. The classification of some of these biotopes is tentative (part of biotope in brackets) as the faunal composition does not fit the biotope descriptions perfectly. An additional two biotopes have tentatively (for the same reasons as with the camera footage) been classified within the sediment samples: SS.SSa.CMuSa.(AalbNuc) and SS.SMx.CMx.(MysThyMx). The fauna include C. lloydii, M. rugosa, T. communis, P. maximus, A. opercularis, featherstars and various polychaetes as well as brittlestars including Amphiura sp., Ophiura sp and O. nigra. Of particular note is the presence of maerl beds in the northern and outer Lamlash Bay regions, an important biological feature shown to harbour disproportionately high diversity and abundance of associated organisms in comparison with surrounding habitats.

72

It has been recommended that future monitoring using photographic (stills photography and video) and sediment sampling surveys should be carried out at 2 year intervals to assess any changes and benefits of the establishment of the NTZ in Lamlash Bay.
