In March of 2010, the U.S. Geological Survey (USGS) conducted geophysical surveys offshore of Petit Bois Island, Mississippi, and Dauphin Island, Alabama. These efforts were part of the U.S. Geological Survey Gulf of Mexico Science Coordination partnership with the U.S. Army Corps of Engineers (USACE) to assist the Mississippi Coastal Improvements Program (MsCIP) and the Northern Gulf of Mexico (NGOM) Ecosystem Change and Hazards Susceptibility Project by mapping the shallow geologic stratigraphic framework of the Mississippi Barrier Island Complex.
These geophysical surveys will provide the data necessary for scientists to define, interpret, and provide baseline bathymetry and seafloor habitat for this area and to aid scientists in predicting future geomorphological changes of the islands with respect to climate change, storm impact, and sea level rise. Furthermore, these data will provide information for barrier island restoration, particularly in Camille Cut, and protection for the historical Fort Massachusetts on Ship Island, Mississippi. The dataset herein is a complete side scan sonar backscatter image for the study area offshore of the above-mentioned area. For more information refer to; http://ngom.usgs.gov/gomsc/mscip/index.html.
The U.S. Geological Survey - St. Petersburg Coastal and Marine Science Center assigns a unique identifier to each cruise or field activity. For example, 10CCT02 tells us the data were collected in 2010 (10) for the Coastal Change and Transport (CCT) study and the data were collected during the second (02) field activity for that project in that calendar year. Refer to <http://walrus.wr.usgs.gov/infobank/programs/html/definition/activity.html> for a detailed description of the method used to assign the field activity ID.Data were collected using the research vessel R/V Tommy Munro. Side scan sonar and interferometric swath bathymetry data were collected simultaneously along the tracklines. The side scan sonar towfish was flown off the port quarter astern of the vessel. The interferometric swath transducer was pole-mounted off the starboard quarter of the research vessel. Navigation was acquired with a Coda Octopus F190 Precision Attitude and Positioning System and differentially corrected with OmniSTAR GPS constellation. See the digital FACS equipment log for details about the acquisition equipment used. Both raw datasets were stored digitally and processed using SEA Ltd. Swath Processor version 3.07 and CARIS HIPS and SIPS software version 7.0 in the USGS St. Petersburg office. For more information on processing, refer to the Equipment and Processing page. Chirp seismic reflectivity data were also collected during this survey and are archived separately.

The accuracy of the data is determined during data collection. This dataset is from a single cruise and therefore internally consistent. Methods are employed to maintain data collection consistency aboard various platforms. During mobilization, each piece of equipment (swath and sonar) is isolated to obtain internal and external offset measurements with respect to the survey platform. All the critical measurements are recorded manually and digitally and entered into their respective programs for calibration. Once calibration status is considered acceptable then survey operations commence. Each system has a dedicated computer and efforts are made to utilize the same equipment and software versions. However, upgrades and changes occur and require additional setup, measurements, and notation. The swath transducer sonar head was pole-mounted on the starboard side of the vessel. Offsets between the sonar head and the DGPS antennas were measured and entered into the F190 internal setup program. Differential Global Positioning System (DGPS) is normally provided through the OmniSTAR High Performance wide-area GPS service unless otherwise noted.
This data set was completed on a single and continuous cruise over four days from the same research vessel platform.
There may in some cases be data missing and inconsistent with reported tracklines. This is directly due to the exclusion of poor data, instrument failures, or for the sake of consistent spatial resolution.
The ship was navigated using the Coda Octopus F190 Precision Attitude and Positioning System. The software used is the F180 Series version 4.0.5. Two antennas received the integrated OmniSTAR High Performance DGPS correction. The software used is F180 Series version 4.0.5. The horizontal accuracy of bathymetric data is at the limit of OmniSTAR, a wide-area differential GPS service, which is within 20 cm. Unless noted, all DGPS data are referenced to WGS84. The swath transducer sonar head was pole-mounted off the starboard quarter of the vessel. Offsets between the sonar head and the DGPS antennas were measured and entered into the F190 internal calibration and setup program.

Side scan data acquisition was at sea, collected with a Klein 3900 dual-frequency towfish flown port-quarter of the R/V Tommy Munro. Data was acquired using SonarPro v.11.3 during a cruise in March 2010. Data were collected along planned tracklines approximately 150 meters apart at an average vessel speed of 4 knots. Navigation was calculated by means of DGPS satellite constellation position feed. Navigation data acquisition was at sea, collected with a real-time DGPS system aboard the R/V Tommy Munro. Navigation data were collected in a hydrographic survey software application along planned tracklines approximately 150 meters apart at an average vessel speed of 4 knots.
Within CARIS SIPS v7.0 data were converted from (.xtf) format to digitize altitude, filter speckle noise, and apply AVG and TVG corrections. The corrected lines were then used to create Georeferenced Backscatter Rasters (GeoBARs), which were fully blended into a 1 meter/pixel resolution composite mosaic, which was then exported in GeoTIFF format.

Image pixel values contain acoustic reflectivity values normalized to an 8-bit digital number range (0-255). Lower pixel values correlate with lower signal loss in decibels. The background color is set at pixel value 255 and can be turned off without affecting sonar data values.
