2013-005_299SEDDATA.SHP: Surficial Sediment Data Collected During U.S. Geological Survey (USGS) Cruise R/V RAFAEL 2013-005-FA in H12299 Study Area 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，正在编制沿海海底的详细地质图。最初由NOAA为海图绘制工作采集的水深地形数据（Bathymetric data），为布洛克岛湾（Block Island Sound）该沿岸区域的科研与管理活动提供了基础框架，可反映海底的物质组成与地形特征，并提供沉积物输运及底栖生境（benthic habitat）相关信息。2013年6月，研究团队针对该区域开展实地验证（ground-truth）踏勘调查，采集了海底摄影照片与表层沉积物数据。本数据集的解译成果源自布洛克岛湾采集的多波束回声测深仪（multibeam-echosounder）数据、沉积物数据及摄影数据。如需了解该实地验证调查的更多详情，请访问<http://woodshole.er.usgs.gov/operations/ia/public_ds_info.php?fa=2013-005-FA>。
