Field Activity 2021-016-FA

Identifier 2021-016-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.
Info derived Sediment samples for geological mapping
