08034_KELPROFILES: High-Resolution Seismic-Reflection Chirp Profiles in SEG-Y and JPEG Formats From Cruise RAFA08034 off Edgartown, 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 Edgartown Harbor, Massachusetts. During August 2008 seismic-reflection profiles (Boomer and Chirp) were acquired, and during September 2008 bottom photographs and surficial sediment data were acquired as part of two ground-truth reconnaissance surveys.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数据，为马萨诸塞州该段海岸线沿线的研究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。解释性数据图层源自马萨诸塞州埃德加敦港附近采集的多波束测深仪与侧扫声呐数据。2008年8月获取了Boomer与Chirp型地震反射剖面数据，2008年9月则通过两次地面验证踏勘调查采集了海底照片与表层沉积物数据。
