H12299INTERP: Interpretation of Bottom Features from National Oceanic and Atmospheric Administration (NOAA) Survey H12299 in Block Island Sound (Geographic, WGS 84)

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. Bathymetric data, originally collected by NOAA for charting purposes, provide a fundamental framework for research and management activities along this part of Block Island Sound, show the composition and terrain of the seabed, and provide information on sediment transport and benthic habitat. During June 2013, bottom photographs and surficial sediment data were acquired as part of a ground-truth reconnaissance survey of this area. Interpretations were derived from the multibeam-echosounder, sedimentary, and photographic data collected in Block Island Sound. For more information on the ground-truth survey see <http://woodshole.er.usgs.gov/operations/ia/public_ds_info.php?fa=2013-005-FA>.

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，正在编制布洛克岛海峡沿岸海底的详细地质图。由NOAA最初为海图绘制工作采集的水深测深数据，为该区域的科研与管理活动提供了基础支撑框架，可揭示海底的物质组成与地形地貌，并提供沉积物运移及底栖生境（benthic habitat）相关信息。2013年6月，作为该区域地面验证踏勘调查的一部分，研究团队采集了海底照片与表层沉积物数据。本数据集的解译结果源自布洛克岛海峡范围内采集的多波束测深仪（multibeam-echosounder）数据、沉积物数据及海底摄影数据。如需了解此次地面验证调查的详细信息，请访问<http://woodshole.er.usgs.gov/operations/ia/public_ds_info.php?fa=2013-005-FA>。
