The U.S. Geological Survey (USGS) conducted a geophysical and sampling survey in October 2014 that focused on a series of shoreface-attached ridges offshore of western Fire Island, NY. Seismic-reflection data, surficial grab samples and bottom photographs and video were collected along the lower shoreface and inner continental shelf. The purpose of this survey was to assess the impact of Hurricane Sandy on this coastal region. These data were compared to seismic-reflection and surficial sediment data collected by the USGS in the same area in 2011 to evaluate any post-storm changes in seabed morphology and modern sediment thickness on the inner continental shelf.

美国地质调查局（U.S. Geological Survey, USGS）于2014年10月开展了一项地球物理与采样调查，研究聚焦于纽约州火岛（Fire Island）西侧近海的一系列依附滨面（shoreface）的沙脊。本次调查沿下滨面（lower shoreface）与内陆架（inner continental shelf）区域开展，采集了地震反射数据（seismic-reflection data）、表层沉积物抓取样品、海底照片及视频资料。此次调查旨在评估飓风桑迪（Hurricane Sandy）对该沿海区域的影响。研究人员将本次采集的数据与美国地质调查局2011年在同一区域获取的地震反射与表层沉积物数据进行比对，以评估风暴后海床地貌及内陆架现代沉积物厚度的变化情况。如需了解WHCMSC野外作业的更多信息，请访问：https://cmgds.marine.usgs.gov/fan_info.php?fan=2014-009-FA.
