5-meter swath bathymetric grid collected by Alpine Ocean Seismic Survey, Inc., offshore of Fire Island, NY in 2014, as part of a collaborative U.S. Army Corp of Engineers and U.S. Geological Survey mapping effort (UTM zone 18N, WGS 84, Esri binary grid file format)

Hurricane Sandy, the largest storm of historical record in the Atlantic basin, severely impacted southern Long Island, New York in October 2012. In 2014, the U.S. Geological Survey (USGS), in cooperation with the U.S. Army Corps of Engineers (USACE), conducted a high-resolution multibeam echosounder survey with Alpine Ocean Seismic Survey, Inc., offshore of Fire Island and western Long Island, New York to document the post-storm conditions of the inner continental shelf. The objectives of the survey were to determine the impact of Hurricane Sandy on the inner continental shelf morphology and modern sediment distribution, and provide additional geospatial data for sediment transport studies and coastal change model development.

2012年10月，大西洋盆地有记录以来规模最大的风暴——飓风桑迪（Hurricane Sandy），对美国纽约州长岛南部造成了严重破坏。2014年，美国地质调查局（U.S. Geological Survey, USGS）联合美国陆军工程兵团（U.S. Army Corps of Engineers, USACE），与阿尔卑斯海洋地震勘测公司（Alpine Ocean Seismic Survey, Inc.）合作，在纽约州火岛近海及长岛西部海域开展了高分辨率多波束测深仪（multibeam echosounder）勘测，以记录大陆架内缘（inner continental shelf）的风暴后状况。本次勘测的目标为明确飓风桑迪对大陆架内缘地貌形态及现代沉积物分布的影响，并为沉积物输运研究与海岸变化模型开发提供补充的地理空间数据（geospatial data）。如需了解WHCMSC野外作业活动的更多信息，请访问：http://cmgds.marine.usgs.gov/fan_info.php?fan=2014-072-FA。
