This grid represents approximately 2800 line kilometers of bathymetric data collected in 2011. These data were collected using an interferometric sonar (Systems Engineering and Assessment Ltd. (SEA) SWATHplus-M (234 kHz)) by the U.S. Geological Survey during USGS survey 2011-005-FA. These bathymetric data were used to define the morphology of the sea floor on the inner-continental shelf offshore of Fire Island, New York to help assess environmental change caused by natural processes and human activities.
