Information to be Derived: Sediment samples and seabed imagery for geological mapping
Summary of Activity and Data Gathered: Visited locations within Stellwagen Bank National Marine Sanctuary. A customized Van Veen grab sampler (SEABOSS) equipped with a video camera and a conductivity, temperature, and depth (CTD) instrument was deployed in drift mode to collect sediment for grain-size analysis, video imagery of the seabed, and measurements of water column properties. Total stations 50; total CTD casts 50; total sediment samples 41; total video drifts (4 to 14 min, 0.8 to 3.2 gigabytes) 50; total seabed images 100; total sediment sample images 82.

Notes: Travel to and from Scituate, MA for day-cruises to Stellwagen Bank.
CTD required as for previous cruises.

|SBE 19plus V2 SeaCAT Profiler CTD||These data were collected with a Sea-Bird CTD (conductivity, temperature, depth) instrument - a SBE 19plus SeaCAT Profiler CTD. In addition to the CTD water column profiling, the CTD is equipped with auxiliary sensors to measure fluorescence and turbidity. This instrument was deployed on the USGS SEABed Observation and Sampling System (SEABOSS). The CTD is mounted horizontally on the SEABOSS frame and its maximum depth is approximately 1 meter above the seabed.||CTD|

|Furuno satellite compass SC-30||The location information for stations was acquired from a satellite navigation receiver (Furuno satellite compass SC-30, GPS receiver) at two second intervals.||Navigation||2017-030-FA_nav (Navigation data collectd aboard the R/V Auk on Stellwagen Bank (Geographic, WGS 84, XLSX and CSV formats).)|
|GoPro camera||Seabed video images were collected using a GoPro digital video camera mounted on SEABOSS to provide ground-truth information for geophysical datasets and are used in seabed interpretations. Frame-grab images were extracted from the video.||Photo|

|Nikon 7100 digital camera||A Nikon 7100 camera was used to take photos of the sediment sample in the grab sampler to document the texture of the seabed surface, the degree of disturbance during sampling, biological features such as worm tubes, and to estimate the volume of sediment collected.||Photo||2017-030-FA_SampleImages (Grab sample still images collected aboard the R/V Auk on Stellwagen Bank (JPEG image format.
