Text Files of the DGPS Navigation Logged with HYPACK Software on April 18, 2010 During U.S. Geological Survey Cruise 2010-010

The U.S. Geological Survey (USGS), in cooperation with the Connecticut Department of Environmental Protection and National Oceanic and Atmospheric Administration (NOAA), 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 Long Island Sound, shows the composition and terrain of the seabed, and provides information on sediment transport and benthic habitat. Interpretive data layers were derived from the multibeam echo-sounder data and sidescan-sonar data collected north of Orient Point, New York. During April 2010, bottom photographs and surficial sediment data were acquired as part of a USGS ground-truth reconnaissance survey of these areas. For more information on the ground-truth survey see https://cmgds.marine.usgs.gov/fan_info.php?fa=2010-010-FA.

美国地质调查局（U.S. Geological Survey, USGS）与康涅狄格州环境保护部、美国国家海洋和大气管理局（National Oceanic and Atmospheric Administration, NOAA）合作，正在编制长岛海峡沿岸海域的详细地质图。最初由NOAA为海图绘制目的采集的影像，为该区域的科研与管理活动提供了基础框架，可反映海底的物质组成与地形特征，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纽约奥连特角以北采集的多波束测深数据（multibeam echo-sounder data）与侧扫声呐（sidescan-sonar）数据。2010年4月，研究团队在针对上述区域开展的USGS地面验证踏勘调查中，采集了海底照片与表层沉积物数据。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?fa=2010-010-FA。
