Location of Sea Floor Photographs Acquired During U.S. Geological Survey (USGS) Cruise 2010-010 in Long Island Sound, North of Orient Point, New York (2010-010_OPBOTPHOTOS, Geographic)

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）与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）合作，正在编制长岛湾沿岸海域的详细地质图。由NOAA为海图绘制目的采集的原始影像，为该区域的科研与管理活动提供了基础框架，可展示海底组成与地形，并提供沉积物运移及底栖生境（benthic habitat）相关信息。解释性数据图层源自纽约州奥里恩角以北采集的多波束回声测深数据（multibeam echo-sounder data）与侧扫声呐数据（sidescan-sonar data）。2010年4月，作为美国地质调查局地面验证踏勘调查的一部分，项目组采集了海底照片与表层沉积物数据（surficial sediment data）。如需了解该地面验证调查的更多信息，请访问http://quashnet.er.usgs.gov/data/2010/10010/
