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 33 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 measurements of water column properties. Purpose: These data are collected to map the seasonal temperature, salinity, density, fluorescence (chlorophyll A), and turbidity configuration of the water column which affect the distribution and availability of plankton and the distribution of fish and invertebrate species.

The data were collected during the descent (downcast) of the SEABOSS to the seabed, its drift over the seabed, and its ascent (upcast) to the water surface. The data values presented here have not been edited or modified. The data accuracy is expected to meet the instrument accuracy specifications. Logical_Consistency_Report: The filenames correspond to the station names. Therefore, the locations of the casts can be acquired from the station locations in the station data summary file (available from the Larger Work). The naming convention for the CTD casts is staXXXX_ctd_data.txt where XXXX corresponds to the station number. Completeness_Report: The Sea-Bird instrument is mounted on the SEABOSS frame. All data (downcast, drift, and upcast) are included. All SEABOSS stations on the cruise have a CTD record. There are a total of 33 CTD data files. Positional_Accuracy: Horizontal_Positional_Accuracy: Horizontal_Positional_Accuracy_Report: Although these files do not contain latitudes and longitudes, that information can be acquired from the related station data summary file (2014-070-FA_station_data_summary available from the Larger Work citation). The CTD downcast is located at the start of the video drift, and the upcast is located at the end of the video drift. The location information for stations was acquired from a satellite navigation receiver (Furuno satellite compass SC-30, GPS receiver) at two second intervals with a horizontal accuracy of 10 m. The navigation antenna is located 5.3 m forward of the SEABOSS deployment location. This offset was not accounted for in the navigation acquisition (navigation fixes represent antenna location). The SEABOSS may also drift away from the survey vessel when deployed to the sea floor. Vertical_Positional_Accuracy: Vertical_Positional_Accuracy_Report: The depth values are based on the instrument's pressure gauge and are relative to the local sea surface. The CTD is mounted horizontally on the SEABOSS frame and its maximum depth is approximately 1 meter above the seabed. Lineage: Process_Step: Process_Description: These data were collected with a Sea-Bird CTD (conductivity, temperature, depth) instrument - an SBE19plusV2 SeaCAT Profiler CTD. This instrument was deployed on the USGS SEABed Observation and Sampling System (SEABOSS). See the cross-references for additional information on this system. The SEABOSS is an instrument developed by the USGS to collect samples and video and photographic images of the seabed to aid in the interpretation of seabed sonar imagery. The CTD is mounted horizontally on the SEABOSS frame and its maximum depth is approximately one meter above the seabed.
