The single-beam bathymetry corrected Global Positioning System (GPS) data was obtained through post processing of the base station data to the concurrent rover data.
This dataset serves as a comprehensive archive for the final Digital Elevation Model (DEM) created by the use of all single-beam bathymetry data collected under the FAN (2015-320-FA), which encompasses data from four separate survey platforms the Research Vessel (R/V) Sallenger (15BIM05), R/V Jabba Jaw (15BIM06), R/V Shark (15BIM07), and R/V Chum (15BIM08). Geographic information system data products include a 200-meter-cell-size interpolated bathymetry grid, trackline maps, and point data files. This data series serves as an archive of processed single-beam bathymetry data, collected from July 22–29, 2015, under USGS Field Activity Number 2015-320-FA. The survey area encompasses more than 300 square kilometers (km2) of nearshore environment from Raccoon Point to Point Au Fer Island.
The data described in this report will provide baseline bathymetric information for future research investigating island evolution, sediment transport, and recent and long term geomorphic change, and will support modeling of future changes in response to restoration and storm impacts.
The goal of the BICM program is to provide long-term data on Louisiana’s coastline and use this data to plan, design, evaluate, and maintain current and future barrier island restoration projects. Petersburg Coastal and Marine Science Center conducted a nearshore single-beam bathymetry survey along the south-central coast of Louisiana, from Raccoon Point to Point Au Fer Island, in July 2015. As part of the Barrier Island Comprehensive Monitoring Program (BICM), scientists from the U.S.
