| 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 | 2 |
| 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 |

| 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 |

| q2_geologic_interp | Interpretation of the seabed geologic substrates in quadrangle 2 of the Stellwagen Bank National Marine Sanctuary region offshore of Boston, Massachusetts based on data collected by the U.S. Geological Survey from 1993-2019. This interpretation is based on multibeam sonar bathymetry, multibeam backscatter imagery, video, photos, and grain-size analyses of samples collected from the seabed in the time period 1993-2019. | Page C Valentine |
