RAFA07034_HRSRPROFILES.TXT: High-Resolution Seismic-Reflection Profiles in SEG-Y and JPEG Formats From the Cruise RAFA07034 in the Vicinity of Woods Hole, Offshore Massachusetts

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 through the Elizabeth Islands, off Cape Cod, Massachusetts. In November 2007, bottom photographs, high-resolution seismic-reflection data, and Surficial sediment data were acquired as part of a ground-truth reconnaissance survey.

For more information on the seismic surveys see http://woodshole.er.usgs.gov/operations/ia/public_ds_info.php?fa=2007-034-FA

These data are also available via GeoMapApp (http://www.geomapapp.org/) and Virtual Ocean ( http://www.virtualocean.org/) earth science exploration and visualization applications.

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）以及马萨诸塞州海岸带管理办公室（Massachusetts Office of Coastal Zone Management, MA CZM）合作，正在编制沿海海底详细地质图。最初由NOAA为海图绘制目的采集的影像，为马萨诸塞州该段海岸线的科研与管理活动提供了基础框架，可展示海床的组成与地形，并提供沉积物运移及底栖生境相关信息。
解译数据层源自马萨诸塞州科德角外、伍兹霍尔周边及伊丽莎白群岛航道区域采集的多波束测深仪与侧扫声呐数据。2007年11月，作为地面验证踏勘调查的一部分，项目组获取了海底照片、高分辨率地震反射数据以及表层沉积物数据。

这些数据还可通过GeoMapApp（http://www.geomapapp.org/）以及Virtual Ocean（http://www.virtualocean.org/）这两款地球科学探索与可视化应用获取。
