Sea-Floor Sediment and Imagery Data Collected in Nantucket Sound, Massachusetts, 2016 and 2017

Two marine geological surveys were conducted in Nantucket Sound, Massachusetts, in May 2016 and May 2017 by the U.S. Geological Survey as part of an agreement with the Massachusetts Office of Coastal Zone Management to map the geology of the sea floor offshore of Massachusetts. Samples of surficial sediment and photographs of the sea floor were collected at 76 sampling sites within the survey area, and sea-floor videos were collected at 75 of the sites. The sediment data and the observations from the photos and videos are used to explore the nature of the sea floor; in conjunction with high-resolution geophysical data, the observations are used to make interpretive maps of sedimentary environments and validate acoustic remote sensing data.

2016年5月与2017年5月，美国地质调查局（U.S. Geological Survey）依托与马萨诸塞州海岸带管理办公室（Massachusetts Office of Coastal Zone Management）达成的合作协议，在马萨诸塞州楠塔基特湾（Nantucket Sound）开展两次海洋地质调查，以绘制马萨诸塞州近海海底地质图。本次调查在调查区域内共布设76个采样点位，采集表层沉积物（surficial sediment）样品与海底照片，并在其中75个点位获取海底视频资料。调查获取的沉积物数据以及照片、视频观测资料可用于探究海底底质特性；结合高分辨率地球物理数据（high-resolution geophysical data），这些观测资料可用于编制沉积环境解译图，并对声学遥感（acoustic remote sensing）数据进行验证。
