From Blowing Wind to Running Water: Unifying Sediment Transport
Laboratory experiments and grain-scale computer simulations during the past decade have led to a more universal understanding of flow-driven sediment transport across flows in oil, water, and air.

Ocean Gyres Observed to Move Poleward
Basin-wide ocean gyres have been observed to be slowly migrating toward the poles and, although natural variations contribute, climate simulations suggest the shift is in response to global warming.

In a Submarine Trough, Permeable Rocks May Lead to Quakes
In Japan’s submarine Nankai Trough, rock permeability is much higher when measured at larger scales, likely because of big fractures and faults that are not captured at small scales.

How Are Sediment Pulses Generated?
A new long-term flume experiment shows that bed load gravel travels downstream in recurring, 10-hour pulses even when water flow and sediment supply are constant.
