SwathPlus and RESON Bathymetric Tracklines collected in the Cape Ann - Salisbury Beach Massachusetts Survey Area (BATHTRACKLINES, Geographic, WGS84)

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 (5-30m 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 (http://woodshole.er.usgs.gov/project-pages/coastal_mass/html/current_map.html). This spatial dataset is from the Cape Ann and Salisbury Beach Massachusetts project area. They were 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.

本数据集依托与马萨诸塞州海岸带管理办公室（Massachusetts Office of Coastal Zone Management, CZM）及美国地质调查局（U.S. Geological Survey, USGS）海岸与海洋地质项目伍兹霍尔科学中心签订的合作协议采集完成。该项目于2003年启动，核心目标是构建区域地质框架数据集，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图件，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关键前置环节。本项目聚焦于马萨诸塞州境内新罕布什尔州边界至科德角湾之间的近岸海域（水深5~30米）。
本次测绘合作采集的数据已以系列美国地质调查局（USGS）公开文件报告的形式发布，相关链接为：http://woodshole.er.usgs.gov/project-pages/coastal_mass/html/current_map.html。本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，其数据于2004年与2005年通过两次独立勘测采集完成，覆盖约325平方千米的内陆架区域。2004至2005年期间，本次勘测采集了高分辨率水深数据与后向散射强度数据。
