Field Activity 2020-012-FA

Identifier 2020-012-FA
Purpose Collect seabed sediment samples for geological mapping project
Location Stellwagen Bank NMS
Summary This cruise was conducted in collaboration with the Stellwagen Bank National Marine Sanctuary, and the data collected will aid research on the ecology of fish and invertebrate species that inhabit the region. The Sanctuary's research vessel, R/V Auk, visited 33 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 measurements of water column properties.
Info derived Sediment samples for geological mapping
Comments Travel to and from Scituate, MA for day-cruises to Stellwagen Bank. CTD required as for previous cruises. Load Auk in Scituate, MA (loading not necessary; Seaboss will be onboard from previous week's cruise)
