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.

On Integrating Sedimentology and Hydrogeology in Streambeds
A new modeling blueprint seeks to unify sedimentology, hydrology, and hydrogeology in the modeling of streambeds.
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.
Planetary Dune Workshop Expands to Include Subaqueous Processes
The Fifth International Planetary Dunes Workshop: From the Bottom of the Oceans to the Outer Limits of the Solar System; St. George, Utah, 16–19 May 2017
What Controls the Shape of Steep Mountain Streams?
The shape of steep river streams changes systematically with channel slope, but field data and theoretical analysis reveal that slope is not the sole factor in setting a channel’s form.
Lab Tests Probe the Secrets of Steep and Rocky Mountain Streams
Researchers built a glass-encased test environment that helps them assess streamflow without the confounding factors introduced by bed forms.
Boulders Limit Transport of Sand and Gravel in Steep Rivers
Mountain rivers and streams actively reshape landscapes by eroding material from uplands and depositing it in lowlands. Scientists can now predict this transport in very steep streams.
Evidence Found for China's Ancient Origin Story
New geological findings suggest that an ancient flood in a popular legend about the birth of China's civilization might have actually occurred, but some 150 years later than historians thought.
The Mathematics of Braided Rivers
River researchers find a mathematical relationship that predicts the average shape of a riverbed over a defined distance, opening the door to new ideas about modeling braided rivers.
Plunging into Waterfall Sediment Transport Modeling
A first-of-its-kind model describes how pools at the base of waterfalls adjust their depth to keep up with sediment flow.
