Abstract:

The main objectives of the study are to characterize the sedimentary structures observed in the area where internal waves interact with the seafloor and to identify the interaction and breaking mechanisms that result in seafloor erosion and sediment resuspension. We imaged the water column and the sub-seafloor with a ParaSound sub-bottom profiler off Namibia (SE Atlantic Ocean). The data was collected during R/V METEOR cruise M122 in 2016.
