Information to be Derived: Sediment samples and seabed imageryfor geological mapping
Summary of Activity and Data Gathered: 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 41; total CTD casts 41; total sediment samples 30; total video drifts (5 to 18 min, 1.1 to 3.9 gigabytes) 41; total seabed images 82; total sediment sample images 65.
Staff: Dann Blackwood
Notes: Travel to and from Scituate, MA for day-cruises to Stellwagen Bank.
CTD required as for previous cruises.
