Erosional furrows on continental shelf edge, Mississippi delta region

Abstract

Erosional furrows are recognized on the seafloor off the Mississippi Delta, trending downslope over the shelf edge. They occur in water depths of 150 to 380 m seaward of presently active mudslides on the delta slope. The furrows cross an area of former mudslide deposition and part of the outer shelf. Their origin is likely to be related to cross-shelf secondary helical flows, although delta-front mass movement could cause similar erosional gouging.
