Earth's rotation affects flows in submarine channels

Coriolis forces due to Earth's rotation deflect winds and ocean flows to the right in the Northern Hemisphere and to the left in the Southern Hemisphere. In sinuous submarine channels, Coriolis forces can drive secondary circulation of turbidity currents and determine where erosion and sediment deposition occur. Researchers conducted laboratory experiments with a channel in a rotating tank to study the conditions under which Coriolis forces dominate the channel flow and to investigate how these forces affect sediment deposition in large-scale submarine channels.
