Bottom photographs collected in the Cape Ann - Salisbury Beach Massachusetts Survey Area (SEABOSS_Photos)

These data were collected under a cooperative agreement with the Massachusetts Office of Coastal Zone Management (CZM) and the U.S. Geological Survey, Coastal and Marine Geology Program, Woods Hole Science Center. 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 reserves, and assessing environmental changes due to natural or human impacts. The project is focused on the inshore waters (5-30 m deep) of Massachusetts between the New Hampshire border and Cape Cod Bay. Data collected for the mapping cooperative have been released in a series of USGS Open-File Reports (https://woodshole.er.usgs.gov/project-pages/coastal_mass/). This spatial dataset is from the Cape Ann and Salisbury Beach Massachusetts project area. The data collected in two separate surveys in 2004 and 2005 and cover approximately 325 square kilometers of the inner continental shelf. High resolution bathymetry and backscatter intensity were collected in 2004 and 2005. Seismic profile data, sediment samples and bottom photography were also collected in 2005.

本数据集基于与马萨诸塞州海岸带管理办公室（Coastal Zone Management, CZM）以及美国地质调查局海岸与海洋地质项目伍兹霍尔科学中心签订的合作协议采集获得。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、划定海洋保护区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。本项目聚焦于马萨诸塞州新罕布什尔州边界至科德角湾之间的近岸海域（水深5至30米）。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）的形式发布，详情可参阅链接：https://woodshole.er.usgs.gov/project-pages/coastal_mass/。本次空间数据集源自马萨诸塞州安角与索尔兹伯里海滩项目区域。该数据集基于2004年与2005年两次独立勘测采集所得，覆盖约325平方千米的内陆架海域。2004年与2005年期间采集了高分辨率水深测量数据与反向散射强度数据。2005年还同步采集了地震剖面数据、沉积物样品与海底摄影资料。
