Sedimentary waves on the Namibian continental margin and in the Argentine Basin - Bottom flow reconstructions based on high resolution echosounder data.

Abstract

During several cruises of the German Special Research Project 261 - The South Atlantic in the late Quaternary - to the South Atlantic Ocean, high resolution narrow beam echosounder data revealed sinusoidal structures in deep sea sediments, which showed a conspicuous spatial regularity over large areas in conjunction with pronounced internal layering. They were observed both in the Southeastern and in the Southwestern Atlantic Ocean, and specifically investigated in this study on the Namibian continental margin as weIl as in the central Argentine Basin.
