Furrows and channels in Scan Basin, southern Scotia Sea: tracking the path of the Weddell Sea Deep Water?

Multibeam bathymetry and parametric echo-sounder profiles show the nature of the surficial morphology and the most recent sub-surface sediment record of Scan Basin, a key area to track the path of bottom waters from Weddell Sea to Scotia Sea. We particularly focus in the southern part of the basin, where the identification of a number of channel-like features records the inception of the Weddell Sea Deep Water (WSDW) in the basin. A clear morphological distinction is observed between channels located at both sides of the basin, which most likely suggest a different degree of interaction between oceanographic and tectonic factors.
