USGS SIR-2004-5198 Benthic Community of Offshore Banks 1 PURPOSE Benthic
habitat on the United States continental shelf of the Atlantic coast and Gulf of Mexico isnot a homogeneous region of flat mud habitat, but also contains natural bathymetric highs
including ridge and shoal features. Many of these ridge/shoal features (e.g., Heald Bank,
Sabine Bank, Ship Shoal) are sand banks which have already been identified ascontaining exploitable deposits. For example, it is estimated that Ship Shoal, located off
of Louisiana, contains 1.6 billion cubic yards of sand appropriate for renourishment and
stabilization projects (Research Planning, Baird Associates & Applied Marine Services,2001). As nearshore reserves become depleted, offshore sand resources are becoming
more important and proposed projects to use these sediments call for a range of a hundred
thousand to several million cubic yards of sand to be taken (EMSAGG, 2003). In 2002,the Minerals Management Service (MMS) received requests for 15 million cubic meters
of sand to be used for projects off of Florida, Louisiana, Maryland, South Carolina, and
Virginia (EMSAGG, 2003). Sediments mined from offshore sources are being used to
keep up with increased beach renourishment cycles, repair storm damage, preventerosion, and prevent wetland loss due to anthropogenic alteration and sea level rise
(Research Planning, Baird Associates & Applied Marine Services, 2001). The Minerals
Management Service (MMS) Leasing Division has the responsibility for determining theimpact of mineral resource development excluding oil, gas, or sulfur. Before offshore
sand resources are exploited, MMS is tasked with creating a synopsis which details not
only what background information is known about potential sand mining areas but alsowhat important information has not yet been collected. The U.S. Geological Survey
(USGS), as part of a continuing long term policy to help address MMS information needs
in the region, will undertake research to address those topics to provide an integrated
basis of understanding of structure and function of key biological communities. Thisreview serves as background information that MMS and others can utilize to estimate
both the potential direct and indirect impacts of any proposed removal activities to
natural sand banks on the Gulf of Mexico or U.S. Atlantic shelf. Direct impacts,potentially the most recognizable and easily detectable, include the actual removal of
infauna and changes in sediment topography. Indirect impacts include those that affect
both recolonization of the original benthic community (e.g., changes in sediment grainsize) and higher trophic levels (e.g., fish response to changing prey) (Research Planning,
Baird Associates & Applied Marine Services, 2001). BACKGROUND Sand areas on the
outer continental shelf provide habitat for many benthic infaunal organisms (e.g.,polychaetes, bivalves, amphipods) and epibenthic (e.g., crabs, gastropods) invertebrates
(Hobbs, 2002; Posey et al., 1998). Species diversity and abundance are comparable to
nearshore and intertidal areas (Posey et al., 1998). Along the continental shelf, the
-

7/45
distribution of benthos may not be uniform, but rather patchily distributed. For example,
Cutter and Diaz (2000) found the quality of benthic habitat to be higher in structured
versus homogeneous sand areas. Part of this patchiness may be explained by microhabitatdifferences created by ridge and shoal structures (Sisson et al., 2002) which provide
distinctive habitats in an otherwise structureless bottom. Raised sand banks provide
unique microhabitat based upon a combination of sediment USGS SIR-2004-5198Benthic Community of Offshore Banks 2 grain size and energy regime (Bergen et al.
2001). Thus differences in the resident benthic community may exist between areas on
the bank, in the surrounding areas, and in the ecotone between the bank and surroundingareas. Previous work off of the U.S. East Coast supports this hypothesis (Hobbs, 2002). If
differences in the spatial distribution of benthic biomass could be explained based upon
microhabitat features, it has implications to predicting not only benthos distribution but
the organisms that reply upon them as a food or structural resource as well. Many finfishspecies settle out onto sand banks as juveniles and exploit sandy shoal areas for both
habitat and feeding purposes. For example, juvenile red snapper have been found to
utilize low-relief habitat (Szedlmayer and Conti, 1999) where their diet is dominated by
small crustaceans common to sand sediments (Dr. William Patterson-University of WestFlorida, pers. comm.). Other resident fishes, such as flatfish (e.g., flounder, sole) reside in
sandy areas for their entire life cycle. Flatfishes tend to undergo an ontogenetic shift intheir diet. As juveniles, flatfish feed primarily upon annelids, switching to crustacean and
bivalve prey as they increase in size (Rijnsdorp and Vingerhoed, 2001). The presence of
benthic assemblages is important not only as food but also for the sediment stabilization
and biogenic structure they provide. Tube, mound, and burrow construction byinvertebrates provides a distinct habitat and many juvenile fish have been found to
associate with such biogenic structures to avoid predation (Kaiser et al., 1999). Thus, any
alterations to resident benthic or epibenthic invertebrate communities could have bothtrophic and habitat effects. Benthic infaunal invertebrate communities can be broken
down into macrofauna (>0.5 mm) and meiofauna (0.063 - 0.5 mm) components and
generally have a relatively low mobility compared to nekton. Benthic infauna are directlytied to the substrate in which they live and thus, benthic communities are highly
susceptible to anthropogenic activities such as sand mining which may either directly or
indirectly alter the sediment environment. One direct effect of sand dredging is the actualremoval all of the infaunal organisms within the immediate area. High recruitment back
into the disturbed area can lessen the impact to higher trophic levels and restore a stable
community. For this reason, it has been suggested that seasonal considerations are made
before any dredging is performed. For example, Hobbs (2002) recommends that sandmining off of the coast of Maryland and Delaware take into account higher infaunal
recruitment rates during spring and summer. Isolated disturbed areas have restricted
recovery as only opportunists persist such as errant polychaetes, mobile amphipods, andscavenging isopods with recolonization by large sedentary fauna (e.g., bivalves) restricted
(Hacking, 2003). Thus, a second suggestion in ameliorating the effects of dredging via
increased recolonization is to leave undisturbed islands during sand removal activities(Byrnes et al., 1999, Hobbs, 2000, Hobbs, 2002). If islands are left they may serve as a
colonizer source allowing rapid return of the original community. Other potential direct
effects of sand dredging include changes in grain size, bathymetry (Drucker et al., 1995),
and shear stress (Hobbs, 2002) which may alter the faunal community recruiting into the
-

8/45
disturbed area, possibly preventing a return of the original community. Dredging of
sediment resources can also have indirect effects. Changes in sediment parameters (i.e.,
grain size, organic content) may create long term changes in sediment suitability leadingto a change in species composition (Hacking, 2003). Sediment resuspension is another
indirect effect that can impact not onlythe immediate benthic community but also the
surrounding community structure due to differential susceptibility of fauna to eitherburial of adults/recruits (Miller et al., 2002), and/or prevention of effective suspension
feeding (Rhoads and Young, USGS SIR-2004-5198 Benthic Community of Offshore
Banks 3 1970). A change in the resident benthic community may then have indirectimpacts to higher trophic levels which are dependent upon benthos composition for its
resource value (Kenny & Rees, 1996). Small changes in habitat quality or resource value
that affect either the growth and/or survival of juvenile fishes may have eventual large
impacts on fish population size (Diaz et al. 2003). GOAL AND OBJECTIVES GOALThe goal of this synopsis was to synthesize the state of knowledge and identify gaps in
the current understanding of the dominant benthic assemblages of natural sand bank areas
on the U.S. East and Gulf Coast Continental Shelf. OBJECTIVE A Synthesize the
existing scientific literature on the dominant offshore benthic assemblages residing alongthe U.S. East and Gulf of Mexico continental shelf. Additionally, highlight data
deficiencies or questions that remain to be answered. Fulfillment of this objectiveprovides a synthesis ofbiological information for assessing the complications and/or
benefits of dredging in specific areas. OBJECTIVE B Synthesize existing literature
which links the dominant offshore benthic assemblages identified in Objective A to
particular sediment types and bathymetry. Knowledge of the sediment type andbathymetry of an area could be used to estimate the type of communities that are likely to
be present if consistent relationships exist. One concern of MMS is the ability to prepare
an adequate environmental assessment in areas where a site-specific study has not beenconducted. OBJECTIVE C Examine existing literature which identifies the effects of
sand dredge/mining activities on the dominant offshore benthic assemblages identified in
Objective A. Special attention will be given to estimates of recovery time for benthicassemblages post anthropogenic impact. OBJECTIVE D Organize all of the scientific
literature collected for Objectives A-C into a ProCite database. The assembled ProCite
database provides scientists access to an easily searched database providing data forinformed management decisions. METHODS The collection of information regarding
benthos community structure, abundance, and biomass at potential offshore sand mining
areas was carried out using standard Internet search engines, electronic databases, and
individual library searches. Internet search engines were used to search for informationavailable at the level of individual state agencies, and focused on information that was
either unpublished or generally unknown outside of the specific agencies themselves.
USGS SIR-2004-5198 Benthic Community of Offshore Banks 4 That information wassecured through personal contact with agencies whenever possible. In addition, thirteen
electronic databases (Table 1) were searched with a series of key words used as search
parameters. At least thirteen key words (Table 2) were used in an intensive search of eachdatabase, either alone or in combination with one another. Relevant sources were either
obtained at specific libaries (i.e., University of South Florida, USGS FISC-CARS), or
through interlibrary loan. The research library at Mote Marine Laboratory, Sarasota,
Florida, USA, was also searched for pertinent reports. Additionally, the literature cited

relevant to include in the review, emphasis was given to literature with a focused study
area within federal waters (i.e., 3 nautical miles or greater offshore for all coastal statesexcept 5 for Texas and Florida). Specifically, literature was selected which provided
general benthic invertebrate community structure information in offshore areas in the
Gulf of Mexico and western Atlantic Ocean (U.S. East Coast) as well as any impacts of
dredging operations on offshore benthic communities. Some nearshore studies, and a fewof estuarine nature, were included if their specific focus was on the impacts of dredging.
Relevant information on study sites, collection methods, results, and overall conclusions
was extracted from each source and organized into the ProCite 5 program designed by
Thomson ISI Researchsoft, a literature reference database creation program. The ProCitedatabase was organized by the authors last name, with the main database screen
displaying the author(s) name, title, date, and key words upon opening. The main screencan be sorted and searched. Each entry also contains a searchable notes section. The
first part of the notes section details what type of study it was (ecological survey,
experimental, or literature review), the geographic area in which the study was
conducted, the relative scale of the study (m-kms), the average depth USGS SIR-2004-5198 Benthic Community of Offshore Banks 5 range of the study, the benthos collection
method (e.g., sample processing, sieve size) utilized, the environmental data (water
parameters) collected, the habitat parameters (e.g., sediment particle size, habitat type)collected, and the sampling season of collection. The second part of the notes section
details the major findings of each study. When available, the summary included
information on dominant taxa in terms of abundance, dominant taxa in terms of biomass,spatial distribution patterns, environmental parameter correlations, habitat parameter
correlations, indications of post-disturbance fauna recovery times, indications of any
long-term differences between impacted versus non-impacted areas, details aboutdredging operations, and any general notes pertinent to the objectives of this review.

words cited in the actual literature but were selected to standardize all records in theProCite database. The chosen key words indicate the location of the study (northern East
Coast, southern East Coast, eastern Gulf of Mexico, or western Gulf of Mexico), the state
off of which the study was conducted, and type of study (experimental, survey, orreview). Any study in which a manipulation was performed (e.g., sediment colonization
boxes, planned sediment disposal) was designated as an experimental study. If the natural
fauna within an area was sampled but no environmental manipulation was performed, the
study was designated as a survey. Studies that synthesized the literature but did not

provide any new data were designated as review papers. Additionally, if specific
geographic coordinates were given for sample locations within the text USGS SIR-2004-
5198 Benthic Community of Offshore Banks 6 then the key word geographiccoordinates was selected for that entry into the database. The information gathered was
incorporated into data tables, in addition to ProCite, for final presentation, including
spatially explicit information on distribution and comparison of dominant benthicassemblages within or near potential sand removal areas, correlations between benthic
assemblages and sediment characteristics and/or bathymetry, post-dredging recovery
times, and the resistance, resilience, or alternative states of dominant benthic assemblagesin response to dredging impacts. Within the results section, the Gulf of Mexico and East
Coast were divided into east-west and north-south regions to extract any regional
differences. The Mississippi River marks the separation of regions in the Gulf, while on
the East Coast, the northern region encompasses those states north of, and including,Delaware. Maryland and states to the south are considered the southern East Coast
region. In addition, the numbers found in parentheses throughout the results text indicate
a specific study, based upon the study reference numbers presented in Table 3. Lastly,
current data gaps in information available on the impacts of sand/mining dredging to thebenthic infaunal community are highlighted. RESULTS A. General Overview One
hundred and twenty-two annotated entries, spanning references from 1954-2003 andencompassing numerous peer reviewed journal articles and governmental reports, are
included in the database (Table 3). Database entries emphasized the Gulf of Mexico and
U.S. East Coast, although several papers were also included from locations outside these
two areas (Appendix A). For the purpose of this report, only the results of those papersfrom the Gulf of Mexico and East Coast are analyzed, a total of 95 papers. Some papers
are combinations of experimental type (Review/Survey, Survey/Experimental, etc.) or
location (N/S East Coast or E/W Gulf of Mexico) (Table 3). The remaining papers wereeither studies which discussed general dredging effects and/or discussed dredging
impacts from other countries. Surveys were the most common type of study, representing
over 50% of all of the papers in the database, and over 75% of the studies from the Gulfof Mexico and East Coast (Table 4). No survey studies included a comparison of fauna
from the U.S. East Coast to the Gulf of Mexico. In the Atlantic, surveys were almost
evenly divided between the northern and southern East regions. In the Gulf of Mexico,the majority of the surveys (64%) were exclusive to the area east of the Mississippi River.
Additionally, five surveys spanned the reviews pre-set geographical boundaries, with
four of the surveys extending between the north and south East, and one survey
conducted at sites in both the eastern and western Gulf of Mexico (Table 5). USGS SIR-2004-5198 Benthic Community of Offshore Banks 7 Table 3. A listing of all studies
included in the ProCite database, with an assigned reference number for each entry. These
reference numbers will be used for annotation in the results section. When major taxawere discussed in the literature they were included in the table and if a taxon was cited as
dominant, then it is underlined. More than one taxon was underlined if both a
macrofaunal and meiofaunal component were discussed. The study type is listed for eachstudy: Experimental (E), Review (R), or Survey (S). The location of each study along the
United States East and Gulf Coast is listed: Northern East Coast (N), Southern East Coast

2003 USGS SIR-2004-5198 Benthic Community of Offshore Banks 23 Twenty-fourreview papers were included in the database. Of these, 17 were from the Gulf of Mexico
or East Coast (Table 4). The majority of these review papers were from the eastern Gulf
of Mexico and northern East Coast. Two of the 16 reviews spanned geographicalboundaries, with one covering the eastern and western Gulf of Mexico and the other
extending over the northern and southern East Coast (Table 5). Only one review paper
was found which synthesized solely southern East Coast fauna. Of the review papers, onealso had an experimental component, and was from the northern East Coast (Table 5).

these, only five were from our areas of interest, the Gulf of Mexico and East Coast (Table4). Two experimental studies were conducted in the northern East Coast, although one of
these was in combination with a review, and there was one experimental study performedin the southern East Coast. There was also one experimental study, combined with a
survey, spanning both the northern and southern East Coast (Table 5). Within the Gulf of
Mexico, there was one experimental study conducted in the eastern portion, but no
experimental studies conducted in the western Gulf of Mexico (Table 5). The depth ofbenthic surveys spanned 1-800 m in the Gulf of Mexico (Table 3). The depth range of
surveys conducted in the East Coast ranged from 1-2,500 m. A survey conducted by
Sanders (1968) contained a study site on the abyssal rise south of New England at 2,500meters, which was the deepest location of all the studies examined. Twelve survey studies
in the Gulf of Mexico and 16 on the East Coast examined the nearshore depth range of 5-
15 meters, which is most appropriate to the depth range that natural sand banks, ridges,and shoals are found in. Only survey and experimental papers were tabulated to examine
patterns in the following sections of the results: taxonomic information, collection

taxon in 8% of the Gulf of Mexico studies, but were a dominant taxon only in the eastern
region. While most papers only examined macrofauna, a few studies included meiofauna
as well. In the Gulf of Mexico, nematodes were the dominant meiofauna found in theeast, and foraminiferans in the west region. Information on numerical dominance by
individual species was also available from a limited number of studies. Four polychaete
taxa were identified as predominant species in five or more surveys (>20% of the surveystudies) from the Gulf of Mexico including Paraprionospio pinnata, Mediomastus,
Prionospio and Cossura (Table 7). Paraprionospio pinnata was the most commonly cited
dominant species (35%) in the Gulf of Mexico, which included surveys from both eastand west of the Mississippi. Cossura, Mediomastus, Nereis, and Prionospio were all
dominant polychaete genera commonly found from studies on both sides of the Gulf.
Sigambra tentaculata and Magelona phyllisae were both common polychaete species, but
only highlighted in surveys from west of the Mississippi River. In the Gulf of Mexico twoof the three most common amphipod species, Acanthohaustorius and Microdeutopus
myersi, along with the archiannelid, Polygordius, were only reported from the eastern
Gulf of Mexico. Ampelisca was the predominant amphipod genera found in the Gulf
(>10%) and was found both east and west of the Mississippi River. The bivalve, Mulinialateralis, was the most commonly reported mollusc in the Gulf. As was true for the Gulf
of Mexico, polychaetes were most commonly recorded as the dominant macrofaunafound in surveys from the East Coast (Table 6). Specifically, 50% of the East Coast
surveys with taxa information listed polychaetes as the dominant macrofaunal
component. Polychaetes dominated in four of seven surveys in the southern East Coast
regions, with the remaining southern studies identifying asteroids, bivalves, andarchiannelids as dominants. Archiannelids, polychaetes, and amphipods were all
dominant taxa reported in USGS SIR-2004-5198 Benthic Community of Offshore Banks
25 surveys from the northern East Coast. Spionidae polychaetes were the most frequentlynoted family within those East Coast surveys that specifically discussed numerically
dominant species (47%) (Table 8). At the genus level, Spiophanes was noted as a
dominant genus in 47% of East Coast surveys, and more specifically, the speciesSpiophanes bombyx, was listed in 44% of surveys from both northern and southern
regions. The polychaete, Prionospio, was found in 22% of the East Coast surveys but
generally only along the southern East Coast. Other common polychaete genera reportedin at least four of the 32 East Coast studies (>10%) were Chone, Clymenella,
Lumbrineris, Nephtys, Nereis, Tharyx, along with the families Aricidea, Sabellariidae,
and Syllidae. Ampelisca and Unicola were the dominant amphipod genera, reported in
28% and 25% of the East Coast studies, respectively. The amphipod species, Unicolairrorata, was noted in 22% of the East Coast surveys. Other dominant amphipod species
reported in East Coast surveys were Byblis, Erichthonius, Protohaustorius, and
Pseudunciola. The dominant bivalve genera reported in East Coast surveys includedEnsis, Nucula, Tellina, and Astarte. Ensis directus and Nucula proxima were commonly
reported bivalve species. The predominant amphipod and bivalve taxa were similar to
both the northern and southern East Coast regions. Other commonly encountered taxa(>10% of the East Coast surveys) included the archiannelid Polygordius, the echinoid
Echinarachnius parma, the decapod Cancer irroratus, and the tanaid, Tanaissus. Table 6.
