Chirp sub-bottom profiler tracklines collected by the U.S. Geological Survey offshore of Fire Island, NY in 2011 (Geographic, WGS 84, Esri Polyline Shapefile)

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. 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.
