Surficial Sediment Data Collected During U.S. Geological Survey (USGS) Cruise R/V RAFAEL 2010-010 in Long Island Sound, North of Orient Point, New York (2010-010_OPSEDDATA.SHP)

The U.S. Geological Survey (USGS), in cooperation with the Connecticut Department of Environmental Protection and National Oceanic and Atmospheric Administration (NOAA), is producing detailed geologic maps of the coastal sea floor. Imagery, originally collected by NOAA for charting purposes, provides a fundamental framework for research and management activities along this part of Long Island Sound, shows the composition and terrain of the seabed, and provides information on sediment transport and benthic habitat. Interpretive data layers were derived from the multibeam echo-sounder data and sidescan-sonar data collected north of Orient Point, New York. During April 2010, bottom photographs and surficial sediment data were acquired as part of a USGS ground-truth reconnaissance survey.

美国地质调查局（U.S. Geological Survey, USGS）联合康涅狄格州环境保护部、美国国家海洋和大气管理局（National Oceanic and Atmospheric Administration, NOAA），正开展长岛海峡沿岸海域的详细海底地质图编制工作。由美国国家海洋和大气管理局为海图编制工作采集的影像资料，可为该区域的科研与管理工作提供基础性支撑框架，同时可呈现海床的组成与地形，并提供沉积物输运及底栖生境相关信息。解释性数据图层源自纽约州奥连特角北侧采集的多波束测深仪（multibeam echo-sounder）数据与侧扫声呐（sidescan-sonar）数据。2010年4月，美国地质调查局在地面验证（ground-truth）踏勘调查中同步获取了海底照片与表层沉积物数据。如需了解该地面验证调查的更多详情，请访问http://quashnet.er.usgs.gov/data/2010/10010/。
