A turbidity current is most typically an underwater current of usually rapidly moving, sediment-laden water moving down a slope; although current research indicates that water-saturated sediment may be the primary actor in the process. Turbidity currents can also occur in other fluids besides water.

What are turbidity currents?

Turbidity currents can change the physical shape of the seafloor by eroding large areas and creating underwater canyons. These currents also deposit huge amounts of sediment wherever they flow, usually in a gradient or fan pattern, with the largest particles at the bottom and the smallest ones on top.

Why is turbidity current important?

Turbidity currents—downhill flows of sediment-laden water that occur in lakes and oceans—are one of the primary processes responsible for transporting sediment from coastal regions to the deep sea.
