|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|
|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|
|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|
|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)|
|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|
|SeaViewer 6000 HD Sea-Drop video camera||Used to guide obstacle avoidance.||Video|
|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|
