Seafloor bedforms in the Gulf of Cadiz. 4B

Image from ROV Argus showing bedforms in the proximal region of the southern channel eroded by the Mediterranean Outflow Water in the continental slope of the Gulf of Cadiz. Linear erosive furrows excavated on the muddy seafloor channel located adjacent to the previous internal margin. These furrows are covered partially by sandy sediment with starved rectilinear to sinuous asymmetric ripples. This starvation allows for the exposure of the mudstone surface over which the ripples are moving. Note that the furrows and ripples in the bottom current agree with the current direction inferred by tracking the suspended particles.
