Field Activity 2017-030-FA

Identifier 2017-030-FA
Purpose Collect seabed sediment samples and seabed imagry 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 50; total CTD casts 50; total sediment samples 41; total video drifts (4 to 14 min, 0.8 to 3.2 gigabytes) 50; total seabed images 100; total sediment sample images 82.
Info derived Sediment samples and seabed imagery for geological mapping

Equipment and datasets

Equipment or measuring device
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.
