Equipment used

Equipment Usage description Data types Datasets
SeaViewer 6000 HD Sea-Drop video camera Used to guide obstacle avoidance. Mounted on the SEABOSS. Video (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. The instruments were 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 1
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
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
Nikon 7100 digital camera Actually a model 7200 for this field activity. Used to take photos of the sediment sample in the grab sampler to document the texture of the seabed surface, the degree of disturbance during sampling, biological features such as worm tubes, and to estimate the volume of sediment collected.
