USGS Collection of Sea Bottom Photographs from the Stellwagen Bank National Marine Sanctuary Region (JPEG images)

The U.S. Geological Survey, in collaboration with the National Oceanic and Atmospheric Administration's (NOAA) National Marine Sanctuary Program, conducted seabed mapping and related research in the Stellwagen Bank National Marine Sanctuary region from 1994 to 2004. The mapped area is approximately 3,700 square km (1,100 square nm) in size and was subdivided into 18 quadrangles. Several series of sea floor maps of the region based on multibeam sonar surveys have been published. In addition, 2,628 seabed sediment samples were collected and analyzed and approximately 10,600 still photographs of the seabed were acquired during the project. These data provide the basis for scientists, policymakers, and managers for understanding the complex ecosystem of the sanctuary region and for monitoring and managing its economic and natural resources.

美国地质调查局（U.S. Geological Survey）与美国国家海洋和大气管理局（National Oceanic and Atmospheric Administration，NOAA）下属的国家海洋保护区项目组合作，于1994年至2004年间在斯特尔瓦根班克国家海洋保护区（Stellwagen Bank National Marine Sanctuary）区域开展海底测绘及相关研究工作。本次测绘覆盖区域总面积约3700平方千米（1100平方海里），被划分为18个四边形图幅。基于多波束声呐（multibeam sonar）勘测数据编制的该区域海底系列地图已正式刊布。此外，本项目期间共采集并分析了2628份海底沉积物样本，获取了约10600张海底静态摄影照片。本数据集为科研人员、政策制定者与管理者深入理解该保护区区域的复杂生态系统，开展其经济与自然资源的监测及管理工作提供了核心依据与支撑。
