Equipment Used: SeaViewer 6000 HD Sea-Drop video camera, SeaBOSS, Nikon 7100 digital camera, Furuno satellite compass SC-30, SBE 19plus V2 SeaCAT Profiler CTD, GoPro camera
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 7; total CTD casts 7; total sediment samples 4; total video drifts (4 to 7 min, 0.9 to 1.5 gigabytes) 7; total seabed images 14; total sediment sample images 6.

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

|Cruise log||(document not focused on specific equipment)||Acquisition and observation log for seabed video and sediment samples collected aboard the R/V Auk on Stellwagen Bank.|
|Survey Equipment||Survey Info||Data Type(s)||Data Collected|
|SeaViewer 6000 HD Sea-Drop video camera||Used to guide obstacle avoidance. Mounted on the SEABOSS.||Video|
|SeaBOSS||The SEABed Observation and Sampling System (SEABOSS) was used to collect sediment samples with a modified Van Veen sampler and video images of the seabed with GoPro cameras mounted on the frame. A CTD was mounted horizontally on the SEABOSS frame.||Surveys (biological)|
|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|
|Furuno satellite compass SC-30||The location information for stations was acquired from a satellite navigation receiver (Furuno satellite compass SC-30, GPS receiver).||Navigation|
|SBE 19plus V2 SeaCAT Profiler CTD||In addition to the CTD water column profiling, the CTD is equipped with auxiliary sensors to measure fluorescence and turbidity. The instruments were mounted on the SEABOSS frame.||CTD|
|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|
