Data Acquired

Survey EquipmentSurvey InfoData Type(s)Data Collected
SeaViewer 6000 HD Sea-Drop video cameraUsed to guide obstacle avoidance. Mounted on the SEABOSS.Video
SBE 19plus V2 SeaCAT Profiler CTDIn 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
SeaBOSSThe 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
Furuno satellite compass SC-30The location information for stations was acquired from a satellite navigation receiver (Furuno satellite compass SC-30, GPS receiver).Navigation
GoPro cameraSeabed 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
Nikon 7100 digital cameraActually 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.Photo
