| Purpose | Collect sediment samples and seabed imagery for geological mapping project. | ||||||||
| Location | Stellwagen Bank, Massachusetts, United States, North America, Gulf of Maine, North Atlantic | ||||||||
| 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 61; total CTD casts 60; total sediment samples 52; total video drifts (3.5 to 14.2 min, 0.8 to 3.1 gigabytes) 60; total seabed images 120; total sediment sample images 0. | ||||||||
| Info derived | Sediment samples and seabed imagery for geological mapping project. | ||||||||
| Comments | Mobilization will be on Friday, May 8, 2015 at SBNMS in Scituate. Demob at the same location. RV AUK is the SBNMS research vessel; 50 ft catamaran. | ||||||||

| Data type: | CTD, Photo, Video, Navigation, Geology |
| Equipment | Usage description | Data types | Datasets |
|---|---|---|---|
| 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 to eleven second intervals. | Navigation | 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 | 3 |
| 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 |
| 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 |
| 35 mm camera | Photo | (no data reported) |

| q2_stations_geology | SeaBOSS | Station locations in quadrangle 2 in Stellwagen Bank National Marine Sanctuary offshore of Boston, Massachusetts where video, photographs and sediment samples were collected by the U.S. Geological Survey from 1993-2019 - includes sediment sample analyses and interpreted geologic substrate. This shapefile contains the quadrangle 2 station locations, interpreted geologic substrate at each location, and description of sampling type (sediment sample, video, photograph). Station locations that have sediment samples include the sediment analyses data. These stations represent information used in the geologic interpretation. | Page C Valentine |
