ARCHEOLOGICAL GUIDELINES

FOR REMOTE SENSING SURVEY WORK

OF AN EXPLORATION PERMIT AREA

1. Collection of Background Information

Prior to conducting fieldwork, the following steps shall be taken by the Permittee’s archaeologist:

a. Consult documents, maps, records or experts as necessary to determine the known history and

prehistory of the area.

b. Obtain maps that are suitable for field plotting of anomalies, sites or archaeological features

encountered.

c. Develop a research strategy for field operations.

2. Field Survey (Remote Sensing) a. Conduct an underwater remote sensing survey of the entire Permit area to locate objects, vessels,

or sites of potential prehistoric or historic significance.

b. The initial survey shall include a magnetometer search of the area. Sonar and other remote

sensing instruments may also be used. Coring or limited test excavations may follow once the

initial survey is completed, but will require a modification to the exploration Permit, as well as

written authorization from the Department of Environmental Protection. The results of any such

testing shall be reviewed in consultation with DHR.

c. The survey will be conducted by a technician qualified to operate and interpret the magnetometer,

its output and any other data, as well as keep accurate horizontal location positioning during the

progress of the survey. Final interpretation of the data and a report of the survey results shall be

conducted in part or in whole and managed by the Permittee’s archaeologist.

d. Remote sensing procedures shall consist of parallel survey lines spaced not more than 50 meters

apart. When anomaly patterns are located during the survey, a sufficient number of lines shall be

run to insure any anomaly clusters are fully defined. If the Permit area includes shore erosion

zones or anchorage areas, these shall be fully surveyed.

e. "X" and "Y" coordinates (Latitude and Longitude) and remote sensing measurements of all

anomalies recorded during the survey shall be listed in an index table and plotted on maps of

sufficient scale and detail to allow for easy relocation should identification and further evaluation

studies be required. Differential GPS, or, with DHR’s approval, any other position-finding

equipment with equal or greater precision, will be used to maintain horizontal positioning during

the remote sensing survey in order to pinpoint all anomalies. The nearest US Coast Guard

differential beacon or, if unavailable or offline, a commercially available differential signal with

an error no greater than a 3 meter radius shall be used for horizontal positioning. Latitude North

and Longitude West readings are to be recorded in degrees, minutes and thousands of a minute

(three decimal places) or greater or the equivalent in decimal degrees or degrees, minutes,

seconds and decimal seconds. The differential GPS unit used for horizontal control during the

survey is to be preset to the NAD 83 (the 1983 North American Datum) prior to the

commencement of survey work.

3. Field Survey (Underwater and Other Data Gathering)

a. If indications of wreckage or any archaeological remains, historic or prehistoric, are discovered as

a result of the remote sensing survey, the Permittee shall conduct an underwater inspection of the

area to verify the presence of archaeological materials. The center of an archaeological site or a

large isolated artifact, such as an anchor or cannon, shall be given an accurate position fix by

keeping a taught buoy line tied to the target on the ocean floor and taking a reading while the

survey boat’s GPS satellite antenna is as directly above the marker buoy as possible. All pertinent

information about the location and nature of the site shall be recorded and reported to DHR.

b. If an historic shipwreck or prehistoric site is located during inspection and verification of

anomalies, the Permittee’s archaeologist shall examine the site to interpret and record its features.

Personnel from DHR may assist in this process. A preliminary site plan or drawing of visible

features, accompanied by a brief written report about the site, and a completed Florida Master

Site File form shall be submitted to DHR within 14 days of the inspection.

c. The primary intent of this Permit is to complete a remote sensing magnetometer survey of the

Permit area to determine the distribution, strength and patterns of anomalies in the Permit area by

locating them through field survey work and subsequently mapping their locations. A secondary

activity of this Permit may include diving to visually determine if anomalies are exposed and can

be identified. Mechanical excavation is strictly prohibited under this Permit. Successful

completion of the Permit depends on conducting the minimum amount of survey specified in the

MINIMUM STANDARDS OF DILIGENCE section of this Permit, keeping good records, filling

out the Daily Field Note/Activity Log provided with this Permit and turning them in on a monthly

basis, and compilation of an acceptable survey report and map(s).

4. Report Content and General Format

a. The report shall discuss the purpose and extent of the exploration Permit, and describe the

location and boundaries of the survey (including a project location map).

b. The methodology used for data collection shall be described in sufficient detail for a reviewer to

understand what was done and why. This shall include, but not be limited to, a discussion of

survey equipment used, weather conditions, survey procedures, types of data collected, recording

techniques, and any special analytical methods and techniques.

c. The report will contain a brief discussion of the history of the general area of the exploration

Permit, with specific reference to any known vessel losses or reported sites in the area. This

information shall be used to correlate remote sensing data collected during the survey with

potential sites.

d. The report shall contain an inventory of all anomalies located by the magnetometer or other

instruments, and a discussion of the results of any visual inspections or other investigation of

identified anomalies. The report shall also include copies of the graphic readouts of all anomalies

considered to be of potential significance by the Permittee including all anomalies the Permittee

has identified for potential excavation activities. Recommendations for additional evaluation of

anomalies shall be prepared with supporting documentation, which should include water depth to

target, depth of burial (as determined from the remote sensing survey), and types of equipment

necessary to identify the target.

e. The report shall include a statement of conclusions about the data, the locations of potentially

significant cultural resources, the need for any additional work to assess site significance and

measures to be taken to reduce the impact to resources.

f. The report must be managed by the Permittee’s archaeologist and include the archaeologist’s

signed statement describing the Permittee’s Permit compliance.

5. Submittal of Report

a. Two (2) copies of the survey report shall be submitted to DHR for review and coordination.

Submission of revised drafts may be required based on reviewer's comments.

b. Copies of survey data (i.e., magnetometer and other sonar records and logs) are required to be

submitted with the reports.

c. Reports and supporting data shall be sent to the Permit Administrator at:

Bureau of Archaeological Research
