SEABOSS Bottom Photographs from the Cruise 2014-046-FA in Narragansett Bay, in JPEG Format

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 framework for research and management activities along southern Narragansett Bay, show the composition and terrain of the seabed, and provide information on sediment transport and benthic habitat. During September 2014, 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 Narragansett Bay. For more information on the ground-truth survey see https://cmgds.marine.usgs.gov/fan_info.php?fan=2014-046-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。水深地形数据（Bathymetric data）最初由NOAA为海图绘制目的采集，可为纳拉甘西特湾南部的科研与管理活动提供基础框架，同时可反映海床的物质组成与地形特征，还能提供沉积物运移与底栖栖息地（benthic habitat）相关信息。2014年9月期间，作为该区域地面验证踏勘调查（ground-truth reconnaissance survey）的一部分，研究团队采集了海底摄影数据与表层沉积物数据。本次解译成果源自在纳拉甘西特湾采集的多波束测深仪（multibeam-echosounder）、沉积物数据及摄影数据。如需了解该地面验证调查的更多信息，请访问https://cmgds.marine.usgs.gov/fan_info.php?fan=2014-046-FA。
