0.5-m Stretched Grayscale Image of the Sidescan-Sonar Data From National Oceanic and Atmospheric Administration (NOAA) Survey H11077 of the Sea Floor in the Vicinity of Woods Hole, Massachusetts (H11077_SSS100_GEO.TIF, Geographic)
收藏资源简介:
The U.S. Geological Survey (USGS), in cooperation with the National Oceanic and Atmospheric Administration (NOAA) and the Massachusetts Office of Coastal Zone Management (MA CZM), is producing detailed geologic maps of the coastal sea floor. Imagery, originally collected by NOAA for charting purposes, provides a fundamental framework for research and management activities along this part of the Massachusetts coastline, shows the composition and terrain of the seabed, and provides information on sediment transport and benthic habitat. Interpretive data layers were derived from multibeam echo-sounder and sidescan-sonar data collected in the vicinity of Woods Hole, a passage between the Elizabeth Islands and Cape Cod, Massachusetts. In November 2007, bottom photographs, seismic-reflection profiles, and surficial sediment data were acquired as part of a ground-truth reconnaissance survey.
美国地质调查局(U.S. Geological Survey, USGS)联合国家海洋和大气管理局(National Oceanic and Atmospheric Administration, NOAA)以及马萨诸塞州海岸带管理办公室(Massachusetts Office of Coastal Zone Management, MA CZM),正着手编制详细的沿海海底地质图。由NOAA最初为海图绘制工作采集的影像资料,为马萨诸塞州该段海岸线沿线的科研与管理活动提供了核心基础框架,可清晰呈现海床的物质组成与地形特征,同时提供沉积物运移及底栖生境(benthic habitat)的相关信息。解释性数据图层源自伍兹霍尔周边区域——即伊丽莎白群岛与马萨诸塞州科德角之间的航道——采集的多波束测深仪(multibeam echo-sounder)与侧扫声呐(sidescan-sonar)数据。2007年11月,作为地面验证踏勘调查的组成部分,项目组还获取了海底摄影资料、地震反射剖面(seismic-reflection profiles)以及表层沉积物数据。
