JPEG formatted images of Knudsen 3202 chirp seismic-reflection profiles collected by the USGS within Red Brook Harbor, MA, 2009

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 (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 (http://woodshole.er.usgs.gov/project-pages/coastal_mass/). This is the spatial dataset for the Red Brook Harbor survey area within Buzzards Bay, Massachusetts. These data are the results of a high-resolution geophysical (bathymetry, backscatter intensity, and seismic reflection) and ground validation (sediment samples and bottom photographs) survey, conducted in 2009.
In addition to inclusion within the USGS-CZM geologic mapping effort, these Red Brook Harbor data will be used to assess the shallow-water mapping capability of the geophysical systems deployed for this project, with an emphasis on identifying resolution benchmarks for the interferometric sonar system.

本数据集依据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）海岸与海洋地质学计划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。该计划于2003年启动，核心目标是构建区域地质框架信息，以服务于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关键前置步骤。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5~30米）。本测绘合作项目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，详情可访问：http://woodshole.er.usgs.gov/project-pages/coastal_mass/。本数据集为马萨诸塞州巴泽兹湾内雷德布鲁克港（Red Brook Harbor）调查区域的空间数据集。本次调查为2009年开展的高分辨率地球物理调查（含水深测量（bathymetry）、反向散射强度（backscatter intensity）与地震反射（seismic reflection））及地面验证调查（含沉积物采样（sediment samples）与海底摄影（bottom photographs）），本数据集即为该调查的成果。
除纳入美国地质调查局-马萨诸塞州海岸带管理办公室地质测绘工作外，雷德布鲁克港的本次调查数据还将用于评估本项目所部署地球物理系统的浅海测绘能力，重点在于为干涉型声呐系统（interferometric sonar system）确定分辨率基准。相关详情可访问：http://woodshole.er.usgs.gov/operations/ia/public_ds_info.php?fa=2009-018-FA。
