Navigation 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.

本次野外作业属于马萨诸塞州波士顿外海的斯特尔瓦根班克国家海洋保护区(Stellwagen Bank National Marine Sanctuary)区域地质基底填图工作的一部分。本次工作的总体目标为基于多波束声呐数据与海底采样，制作分辨率达1:25000的解释性地质地图，用以展示表层地质与海底沉积物动力学特征。本航次与该保护区合作开展，所采集的数据将助力该区域栖息鱼类与无脊椎动物的生态学研究。该保护区的研究船R/V Auk在斯特尔瓦根班克海域布设了75个采样点位，采用搭载摄像机与温盐深仪(CTD)的定制化范维恩采泥器(Van Veen grab sampler，SEABOSS)以漂移模式作业，采集沉积物用于粒度分析、海底视频影像采集，以及水体的温度、电导率与水深测量。关于本次野外作业的更多信息，可通过以下链接获取：https://cmgds.marine.usgs.gov/fan_info.php?fa=2015-062-FA。
