| 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 56; total CTD casts 56; total sediment samples 46; total video drifts (3.5 to 12 min, 0.8 to 2.6 gigabytes) 56; total seabed images 112; total sediment sample images 50. | ||||||||
| Info derived | Sediment samples and seabed imagery for geological mapping | ||||||||
| Comments | Travel to and from Scituate, MA for day-cruises to Stellwagen Bank. CTD required as for previous cruises. | ||||||||

| Equipment | Usage description | Data types | Datasets |
|---|---|---|---|
| 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. Also used to capture images of the recovered sediment samples. | Photo, Video | 3 |
| 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 | 1 |
| SeaViewer 6000 HD Sea-Drop video camera | Used to guide obstacle avoidance. Mounted on the SEABOSS | Video | (no data reported) |
| 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 | 1 |
| 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, Fluorescence, Turbidity | 1 |
