Field Activity 2017-043-FA

Identifier 2017-043-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 39; total CTD casts 39; total sediment samples 37; total video drifts (4 to 10 min, 0.9 to 5.0 gigabytes) 39; total seabed images 78; total sediment sample images 64.
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. Load Auk on Mon Aug 21 in Scituate, MA

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

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, which was needed for stations 4656 and 4662. As the SEABOSS drifted over the seabed, the cameras imaged the seabed at a rate of 60 frames per second from an altitude of ~1 meter.

A Nikon 7100 camera was used to take photos of the sediment sample in the grab sampler to document the texture of the seabed surface, the degree of disturbance during sampling, biological features such as worm tubes, and to estimate the volume of sediment collected.

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.
