What is it about?
Particles in the seabed when agitated by an oscillating current will tend to move downslope under the effect of gravity. This article explores how this effect, combined with known current speeds, may help to create the rounded shape of the uppermost slope or outermost shelf, where it comprises sand.

Why is it important?
Explores the gravity effect on fluxes of saltating particles agitated by oscillating currents. From current meter data and speculations on currents during times of lowered sea level in glacial maxima, we showed that the convexity of the uppermost slope may be linked to the rate of change of current speed with depth, thus linking morphology to properties of the currents if this mechanism has dominated.
