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 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.
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.
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.
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.
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.
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.
Beryllium stored in marine sediments can help scientists study erosion and other environmental changes.
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.
