Sediment echosounder processed data (Atlas Parasound P70 echosounder working area dataset) of RV METEOR during cruise M122, offshore Namibia, South Atlantic Ocean

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.

本研究的核心目标为：对内波（internal waves）与海底相互作用区域内观测到的沉积构造开展特征表征，并明确引发海底侵蚀与沉积物再悬浮的内波相互作用及破碎机制。研究团队于纳米比亚邻近海域（南大西洋东南部），采用ParaSound海底剖面仪对水柱及海底以下地层完成了成像探测。本次研究的观测数据采集于2016年‘流星号’（R/V METEOR）科考航次M122。
