Text files of the navigation logged with HYPACK Software during surveys 07002, and 08002 conducted by the U.S. Geological Survey offshore of Massachusetts within northern Cape Cod Bay (CCB_Hypack_Nav)

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 (https://woodshole.er.usgs.gov/project-pages/coastal_mass/). 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及伍兹霍尔海岸与海洋科学中心（Woods Hole Coastal and Marine Science Center, WHCMSC）达成的合作协议采集。该项目于2003年启动，核心目标是构建区域地质框架信息，为海岸与海洋资源管理提供支撑。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、评估自然或人为活动引发的环境变化的首要关键步骤。本项目聚焦马萨诸塞州沿海近岸水域，作业水深主要集中于3至30米区间。本次制图合作采集的相关数据已通过一系列美国地质调查局公开文件报告（Open-File Reports）对外发布，访问链接为：https://woodshole.er.usgs.gov/project-pages/coastal_mass/。

采集自马萨诸塞州科德角湾北部研究区域的数据包含两类：一是高分辨率地球物理数据，具体包括水深测量数据、反向散射强度数据与地震反射数据；二是地面验证数据，涵盖沉积物样本、视频测线与海底照片。这些数据于2006年至2008年间分五次独立调查完成，覆盖面积达480平方千米的内陆架区域。
