Maps Showing Bathymetry and Modern Sediment Thickness on the Inner Continental Shelf Offshore of Fire Island, New York, Pre-Hurricane Sandy

By W.C. Schwab, J.F. Denny, and W.E. Baldwin

Abstract

The U.S. Geological Survey mapped approximately 336 square kilometers of the lower shoreface and inner continental shelf offshore of Fire Island, New York, in 2011 by 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.
