Field Activity 2015-017-FA

Identifier 2015-017-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 61; total CTD casts 60; total sediment samples 52; total video drifts (3.5 to 14.2 min, 0.8 to 3.1 gigabytes) 60; total seabed images 120; total sediment sample images 0.
Info derived Sediment samples and seabed imagery for geological mapping project.
Comments Mobilization will be on Friday, May 8, 2015 at SBNMS in Scituate. Demob at the same location. RV AUK is the SBNMS research vessel; 50 ft catamaran.

Equipment used

Equipment Usage description Data types Datasets
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 to eleven second intervals. Navigation 1
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
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
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
35 mm camera Photo (no data reported)
