Field Activity 2014-066-FA

Identifier 2014-066-FA
Purpose Collect sediment samples and seabed imagery for geological mapping project.
Location Stellwagen Bank, Massachusetts, United States, North America, Gulf of Maine, North Atlantic
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 44; total CTD casts 43; total sediment samples 28; total video drifts (3.1 to 9.4 min, 0.7 to 2.1 gigabytes) 44; total seabed images 88; total sediment sample images 0.
Info derived Sediment samples and seabed imagery
Comments Mobilization will be on Sunday Sep 21, 2014 at the SBNMS dock at 75 Edward Foster Road, Scituate, MA. Demob at the same location. RV AUK is the SBNMS research vessel; 50 ft catamaran. Entries for this field activity are based on entries from Field Activity 2014-055-FA

Equipment used

Equipment Usage description Data types Datasets
SeaBOSS 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. Surveys (biological), Experiments (biological), Species ID, Photo, Video, Geology, Biology 2
Furuno satellite compass SC-30 The location information for stations was acquired from a satellite navigation receiver (Furuno satellite compass SC-30, GPS receiver). Navigation 1
35 mm camera Photo (no data reported)
SBE 19plus V2 SeaCAT Profiler CTD In addition to the CTD water column profiling, the CTD is equipped with auxiliary sensors to measure fluorescence and turbidity. CTD, Fluorescence, Turbidity 1
GoPro camera Seabed video images were collected using a GoPro digital video camera mounted on SEABOSS to provide ground-truth information for geophysical datasets and are used in seabed interpretations. Frame-grab images were extracted from the video. Photo, Video 2
