| Purpose | Collect sediment samples, photos, video, and ctd data for substrate mapping on Stellwagen Bank in collaboration with Stellwagen NMS scientists. | ||||||||
| Location | Stellwagen Bank, Massachusetts, United States, North America, Gulf of Maine, North Atlantic | ||||||||
| Summary | Visited 75 locations on Stellwagen Bank at which a customized Van Veen grab sampler (SEABOSS) equipped with a video camera and a CTD was deployed in drift mode to collect sediment for grain-size analysis, video imagery of the seabed, and temperature, conductivity, and depth measurements of the water column. | ||||||||
| Info derived | Grain size, Sea floor map | ||||||||
| Comments | Mobilization will be on Friday, Oct 16, 2015 at SBNMS in Scituate. Demob at the same location. RV AUK is the SBNMS research vessel; 50 ft catamaran. | ||||||||

| 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 one second intervals. | Navigation | 1 |
| SBE 19plus V2 SeaCAT Profiler CTD | These data were collected with a Sea-Bird CTD (conductivity, temperature, depth) instrument - a SBE 19plus SeaCAT Profiler CTD. In addition to the CTD water column profiling, the CTD is equipped with auxiliary sensors to measure fluorescence and turbidity. This instrument was deployed on the USGS SEABed Observation and Sampling System (SEABOSS). The CTD is mounted horizontally on the SEABOSS frame and its maximum depth is approximately 1 meter above the seabed. | CTD, Fluorescence, Turbidity | 1 |
| GoPro camera | Seabed video images were collected using a battery-operated, high-definition (1920 x 1080 pixels) GoPro digital video camera mounted on the USGS SEABed Observation and Sampling System (SEABOSS). The SEABOSS system actually had two GoPro cameras attached to it - with the second camera mounted a little higher on the frame which only shows a partial view of the seabed. This second camera was used only to observe obstacles, like gill nets and lobster gear, in order to avoid entanglement. Or, in the case of station 4382, provide a backup system if the primary camera failed. | Photo, Video | 2 |
| 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 and its maximum depth is approximately 1 meter above the seabed. | Surveys (biological), Experiments (biological), Species ID, Photo, Video, Geology, Biology | 2 |
