5 meter ArcRaster hillshade of bathymetry acquired with a SEA Ltd. SWATHplus interferometric sonar offshore of Massachusetts within northern Cape Cod Bay (CCB_FILL_HS Esri BINARY GRID, UTM Zone 19N).

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 (WHCMSC). 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/html/current_map.html). The data collected in the study area located in Northern Cape Cod Bay 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 five separate surveys conducted between 2006 and 2008 and cover 480 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、伍兹霍尔海岸与海洋科学中心（Woods Hole Coastal and Marine Science Center, WHCMSC）签订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、划定海洋资源范围以及评估自然或人类活动引发的环境变化的重要前置步骤。本项目聚焦马萨诸塞州沿海的近岸水域，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美国地质调查局公开文件报告（USGS Open-File Reports）系列形式对外发布，详情可访问：http://woodshole.er.usgs.gov/project-pages/coastal_mass/html/current_map.html。

本次采集的数据集覆盖马萨诸塞州科德角湾北部的研究区域，包含高分辨率地球物理数据（水深测量（bathymetry）、反向散射强度（backscatter intensity）、地震反射（seismic reflection））以及实地校验数据（沉积物样品、视频测线与海底照片）。这些数据采集于2006年至2008年间开展的5次独立勘测，覆盖了480平方千米的内大陆架海域。
