A new study uses the response of optical and acoustic measurements to derive a sediment composition index for prediction of the relative fractions of mixed sediments in suspension.

The Ups and Downs of Tides
The size of tides has changed in the past and will continue to change in the future due to natural and anthropogenic influences on estuaries, coastlines, and near shore regions.

Submarine Rivers of Sediment
Turbidity currents move suspended sediment into the ocean. In general, the more sediment, the stronger the turbidity current, but one process may generate turbidity currents from very dilute rivers.

An Integrated History of the Australian-Antarctic Basin
The first basin-wide compilation of seismic and geologic data shows that both margins experienced similar sedimentation patterns prior to the onset of Antarctic glaciation.

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.

A Complete Picture of Southern Ocean Surface Circulation
For the first time, researchers combine estimates of sea surface height and circulation patterns in both ice-covered and ice-free regions of the Southern Ocean.

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.

Dam Discharge Events Alter Water Flow in an Estuary in Spain
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.
