Field Activity 2014-070-FA

Identifier 2014-070-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 33; total CTD casts 33; total sediment samples 27; total video drifts (2.5 to 4.5 min, 0.6 to 1.1 gigabytes) 33; total seabed images 66; total sediment sample images 0.
Info derived Sediment samples and seabed imagery for geological mapping project.
Comments Mobilization will be on Friday, Dec 12 at Brewer Marine in Plymouth, MA Demob at the same location. RV AUK is the SBNMS research vessel; 50 ft catamaran.

Equipment used

Equipment Usage description Data types Datasets
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. The instrument was mounted on the SEABOSS frame. 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
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) at two second intervals. Navigation 1
35 mm camera Photo (no data reported)
