The U.S. Geological Survey (USGS), in cooperation with the National Oceanic and Atmospheric Administration (NOAA), is producing detailed geologic maps of the coastal sea floor. Bathymetry, originally collected by NOAA for charting purposes, provides a fundamental framework for research and management activities along this part of Rhode Island Sound, shows the composition and terrain of the seabed, and provides information on sediment transport and benthic habitat. Interpretations were derived from the multibeam echo-sounder data collected in Rhode Island Sound. During July 2010, bottom photographs and surficial sediment data were acquired as part of a ground-truth reconnaissance survey of these areas. For more information on the ground-truth survey see <http://quashnet.er.usgs.gov/data/2010/10033/>.

美国地质调查局（U.S. Geological Survey, USGS）与美国国家海洋和大气管理局（National Oceanic and Atmospheric Administration, NOAA）合作，正在编制罗德岛海域沿海海底的详细地质图。最初由NOAA为海图绘制目的采集的水深测量数据，可为罗德岛海域这片沿岸区域的科研与管理活动提供基础框架，其可揭示海底的组成与地形，并提供沉积物运移及底栖生境相关信息。本次解译成果源自在罗德岛海域采集的多波束回声测深仪（multibeam echo-sounder）数据。2010年7月，研究团队针对上述区域开展地面验证踏勘调查，同步获取了海底照片与表层沉积物数据。如需了解此次地面验证调查的更多信息，请访问<http://quashnet.er.usgs.gov/data/2010/10033/>。
