Data Acquired

Survey EquipmentSurvey InfoData Type(s)Data Collected
Nikon 7100 digital cameraA Nikon 7100 camera was 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
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)
