Field Activity 2017-009-FA

Identifier 2017-009-FA
Purpose Collect seabed sediment samples 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 13; total CTD casts 13; total sediment samples 13; total video drifts (6 to 12 minutes, 1.4 to 2.7 gigabytes) 13; total seabed images 26; total sediment sample images 19.
Info derived Sediment samples and photo/video imagery for geological mapping
Comments Travel to and from Plymouth, MA for day-cruises to Stellwagen Bank. CTD required as for previous cruises. Load Auk on Friday, Jan 27 in Plymouth, MA. Entries for this field activity are based on entries from Field Activity 2016-038-FA

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.

Description and usage history of this equipment

Furuno satellite compass SC-30
Navigation
1
The location information for stations was acquired from a satellite navigation receiver (Furuno satellite compass SC-30, GPS receiver) at two second intervals with a horizontal accuracy of 10 m. The navigation antenna is located 5.3 m forward of the SEABOSS deployment location. This offset was not accounted for in the navigation acquisition.

Description and usage history of this equipment

GoPro camera
Photo, Video
2
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 had two GoPro cameras and a Seaviewer camera attached to it. The Seaviewer camera had a live feed to the surface and was used only to observe obstacles, like gill nets and lobster gear, in order to avoid entanglement. In the case of camera failure, the additional cameras provided backup video.

Description and usage history of this equipment

SBE 19plus V2 SeaCAT Profiler CTD
CTD, Fluorescence, Turbidity
1
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.
