This data set contains point locations for data stations in the Stellwagen Bank National Marine Sanctuary Region off Boston, Massachusetts, an area of approximately 1100 nautical square miles. The Stellwagen Bank NMS Mapping Project is designed to provide detailed maps of the Stellwagen Bank region's environments and habitats and the first complete multibeam topographic and sea floor characterization maps of a significant region of the shallow EEZ. Stations represent the location of a sediment sample and/or the end of a video transect. Coordinated Universal Time (UTC) was recorded for each station location; latitude and longitude were later extracted from a GPS navigational log file using this time.
