Powerful submarine flows known as turbidity currents are starting to give up their secrets.
Flume experiments show that a self-reinforcing cycle can strengthen the currents responsible for transporting large amounts of sediment to the deep oceans.
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.
Three-year observations suggest that increased sediment concentrations inhibit vertical transfer of momentum between water layers for more than 2 months after a high-discharge event.
Researchers revisit an old theory about the ethereal patterns of vegetation that form in some arid landscapes.
