Field Activity 2016-038-FA

Identifier 2016-038-FA
Purpose Collect seabed sediment samples and seabed imagery for geological mapping project
Location Stellwagen Bank NMS
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 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.
Info derived Sediment samples and seabed imageryfor geological mapping
Comments Travel to and from Scituate, MA for day-cruises to Stellwagen Bank. CTD required as for previous cruises.

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
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
Nikon 7100 digital camera Images were taken of the surface of the grab samples while still in the grab sampler. Photo 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
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 one second intervals. Navigation 1
