| Purpose | Collect seabed sediment samples and seabed imagery for geological mapping project | ||||||||
| Location | Stellwagen Bank NMS | ||||||||
| Summary | 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 41; total CTD casts 41; total sediment samples 30; total video drifts (5 to 18 min, 1.1 to 3.9 gigabytes) 41; total seabed images 82; total sediment sample images 65. | ||||||||

| Cruise log | Acquisition and observation logs for seabed video and sediment samples collected aboard the R/V Auk on Stellwagen Bank. |
| Equipment | Usage description | Data types | Datasets |
|---|---|---|---|
| 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 instrument was mounted on the SEABOSS frame. | CTD, Fluorescence, Turbidity | 1 |
| 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), Experiments (biological), Species ID, Photo, Video, Geology, Biology | 2 |
| Nikon 7100 digital camera | Images were taken of the surface of the grab samples while still in the grab sampler. | Photo | 1 |
| 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, Video | 2 |
| 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 one second intervals. | Navigation | 1 |
