Station and data summary for data collected on Stellwagen Bank on U.S. Geological Survey field activity 2015-062-FA, aboard the R/V Auk, Oct. 21 and 22 and Nov. 3 and 4 2015 (geographic, WGS84)

This field activity is part of the effort to map geologic substrates of the Stellwagen Bank National Marine Sanctuary region off Boston, Massachusetts. The overall goal is to develop high-resolution (1:25,000) interpretive maps, based on multibeam sonar data and seabed sampling, showing surficial geology and seabed sediment dynamics. This cruise was conducted in collaboration with the Stellwagen Bank National Marine Sanctuary, and the data collected will aid research on the ecology of fish and invertebrate species that inhabit the region. The Sanctuary's research vessel, R/V Auk, visited 75 locations on Stellwagen Bank at which a customized Van Veen grab sampler (SEABOSS) equipped with a video camera and a CTD was deployed in drift mode to collect sediment for grain-size analysis, video imagery of the seabed, and temperature, conductivity, and depth measurements of the water column.

本野外作业隶属于马萨诸塞州波士顿外海斯特尔韦根班克国家海洋保护区（Stellwagen Bank National Marine Sanctuary）区域的地质基底制图工作项目。
本次工作的总体目标为，依托多波束声呐数据与海底采样作业，制作比例尺1:25000的高分辨率解译地图，以展示该区域的表层地质特征与海底沉积物动力学过程。
本次航次与斯特尔韦根班克国家海洋保护区（Stellwagen Bank National Marine Sanctuary）合作开展，所采集的数据将为栖息于该区域的鱼类与无脊椎动物物种的生态学研究提供支撑。
该保护区所属研究船Auk号（R/V Auk）在斯特尔韦根班克海域的75个点位开展采样作业，采用漂移投放模式部署了搭载摄像机与温盐深剖面仪（CTD）的定制化范维恩采泥器（Van Veen grab sampler，SEABOSS），以此采集用于粒度分析的沉积物样品、海底视频影像，并获取水柱的温度、电导率与深度测量数据。
