    "descript": "The U.S. Geological Survey (USGS) mapped approximately 336 square kilometers  of the lower shoreface and inner-continental shelf offshore of Fire Island, New York in 2011 using interferometric sonar and high-resolution chirp seismic-reflection systems.  This report presents maps of bathymetry, acoustic backscatter, the coastal plain unconformity, the Holocene marine transgressive surface and modern sediment thickness.  These spatial data support research on the Quaternary evolution of the Fire Island coastal system and provide baseline information for research on coastal processes along southern Long Island. More information about this field activity and the data collected can be found at the Field Activity Web Page (http:\/\/woodshole.er.usgs.gov\/operations\/ia\/public_ds_info.php?fa=2011-005-FA)",
