How Do Turbidity Currents Accelerate?
Flume experiments show that a self-reinforcing cycle can strengthen the currents responsible for transporting large amounts of sediment to the deep oceans.

How Do Deep-Sea Gravity Currents Transport Sediment So Far?
The first field measurements of turbidity currents flowing around submarine channel bends indicate spiral flow plays a key role in keeping sediment suspended for hundreds of kilometers.
