We have 2 basic objectives: 1) to acquire conduct site survey information at benthic sampling sites occupied by Deep-C researchers, and 2) to explore unknown areas of the seafloor in this region with the objective of learning more about sedimentary processes (sediment type, current reworking, etc) benthic habitats (e.g, hard bottoms, fish burrows, high relief topography). We will be surveying the seafloor with the Teledyne-Benthos C3D interferometric sidescan sonar. Operating at 200 kHz, this system acquires backscatter and high-resolution swath bathymetry at sub-meter-scale resolution.
