PNG formatted images of EdgeTech SB-512i chirp seismic-reflection profiles collected by the U.S. Geological Survey in 2009, 2010, and 2011 offshore of Massachusetts within Vineyard Sound.

These data were collected under a cooperative agreement with the Massachusetts Office of Coastal Zone Management (CZM) and the U.S. Geological Survey (USGS), Coastal and Marine Geology Program, Woods Hole Coastal and Marine Science Center (WHSC). Initiated in 2003, the primary objective of this program is to develop regional geologic framework information for the management of coastal and marine resources. Accurate data and maps of sea-floor geology are important first steps toward protecting fish habitat, delineating marine resources, and assessing environmental changes due to natural or human impacts. The project is focused on the inshore waters of coastal Massachusetts, primarily in water depths of 3-30 meters deep. Data collected for the mapping cooperative have been released in a series of USGS Open-File Reports (http://woodshole.er.usgs.gov/project-pages/coastal_mass/). The data collected in the study area located in Vineyard Sound, Massachusetts includes high-resolution geophysics (bathymetry, backscatter intensity, and seismic reflection), and ground validation (sediment samples, video tracklines, and bottom photographs). The data were collected during three separate surveys conducted between 2009 and 2011 (USGS-WHSC surveys 2009-002-FA, 2010-004-FA, and 2011-004-FA) and cover 340 square kilometers of the inner continental shelf.

本数据集基于与马萨诸塞州海岸带管理办公室（Massachusetts Office of Coastal Zone Management, CZM）、美国地质调查局（U.S. Geological Survey, USGS）海岸与海洋地质项目及伍兹霍尔海岸与海洋科学中心（Woods Hole Coastal and Marine Science Center, WHSC）达成的合作协议采集所得。该项目于2003年启动，核心目标是构建区域地质框架信息，以支撑海岸与海洋资源的管理工作。精准的海底地质数据与地图，是保护鱼类栖息地、划定海洋资源范围、评估自然或人类活动引发的环境变化的重要先行环节。本项目聚焦马萨诸塞州沿海近岸水域，作业水深主要介于3至30米之间。本次测绘合作采集的数据已以一系列美国地质调查局公开文件报告（USGS Open-File Reports）的形式对外发布，相关链接为：http://woodshole.er.usgs.gov/project-pages/coastal_mass/。本次采集的研究区域位于马萨诸塞州葡萄园湾（Vineyard Sound），数据涵盖高分辨率地球物理数据（水深测量、反向散射强度、地震反射数据）以及实地验证数据（沉积物样本、视频测线与海底照片）。数据采集工作于2009至2011年间分三次完成（对应美国地质调查局-伍兹霍尔海岸与海洋科学中心2009-002-FA、2010-004-FA及2011-004-FA三次勘测），覆盖面积达340平方公里的内陆架区域。关于葡萄园湾项目下各次美国地质调查局勘测的详细信息，可查阅伍兹霍尔海岸与海洋科学中心野外活动网页：
