Interpretation of Sedimentary Environments from National Oceanic and Atmospheric Administration (NOAA) Survey H11922 West of Gay Head, Massachusetts, in Eastern Rhode Island Sound (H11922_SEDENV.SHP, Geographic, WGS84)

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 off southern New England, shows the composition and terrain of the seabed, and provides information on sediment transport and benthic habitat. During July-August 2008 NOAA completed hydrographic survey H11922 west of Gay Head, Massachusetts, in Rhode Island Sound and during July and September 2010 bottom photographs and surficial sediment data were acquired as part of ground-truth reconnaissance surveys of this area. Interpretations were derived from the multibeam echo-sounder data and the ground-truth data used to verify them. For more information on the ground-truth surveys see http://quashnet.er.usgs.gov/data/2010/10033/ and http://quashnet.er.usgs.gov/data/2010/10005/

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，正在编制新英格兰南部近海海底的详细地质图。海底测深数据（bathymetry）最初由NOAA为海图绘制用途采集，可为新英格兰南部近海的科研与管理活动提供基础框架，同时可揭示海底的组成与地形，并提供有关沉积物运移及底栖生境（benthic habitat）的相关信息。2008年7月至8月，NOAA在马萨诸塞州盖德角以西的罗德岛海峡海域完成了编号为H11922的水文测量（hydrographic survey）任务；2010年7月及9月，该区域的实地验证踏勘调查采集了海底摄影资料与表层沉积物（surficial sediment）数据。本次解译成果基于多波束测深声呐（multibeam echo-sounder）数据生成，并通过实地验证数据完成校核。如需了解本次实地验证调查的更多信息，请访问http://quashnet.er.usgs.gov/data/2010/10033/ 及 http://quashnet.er.usgs.gov/data/2010/10005/
