Outline of the Multibeam-Bathymetric Data Collected During National Oceanic and Atmospheric Administration (NOAA) Survey H12023 (H12023OUTLINE.SHP, Geographic)

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 and sidescan-sonar 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 2012, 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, sidescan-sonar, 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=2012-002-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，正编制布洛克岛海峡沿岸海床的详细地质图。最初由NOAA为海图绘制工作采集的水深测量（Bathymetric）与侧扫声呐（sidescan-sonar）数据，为该区域的科研与管理活动提供了核心基础框架，这些数据可揭示海床的组成与地形特征，并可为沉积物运移及底栖生境（benthic habitat）相关研究提供支撑信息。2012年6月，研究团队针对该区域开展地面验证（ground-truth）踏勘调查，采集了海底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海峡采集的多波束测深仪（multibeam-echosounder）、侧扫声呐、沉积物及摄影数据。如需了解该地面验证调查的更多详情，请访问<http://woodshole.er.usgs.gov/operations/ia/public_ds_info.php?fa=2012-002-FA>。
