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 Comprehensive Estimate on the Entropy Budget in the Ocean
An analysis of the energy budget in the ocean estimates the Carnot work to be 110 terawatts and the ocean’s Carnot efficiency to be 0.86%.

Eddy Generation in the Central Bay of Bengal
Eddies in the central Bay of Bengal are generated near the eastern boundary of the basin, related to equatorial wind forcing, nonlinearity, and the topographic “bump” of Myanmar.

Dispersal of River Water by Ocean Eddies and Shallow Ekman Flow
Low-salinity water from the Ganga-Brahmaputra river is transported by mesoscale eddies in the Bay of Bengal, but when the monsoon winds strengthen, a shallow “Ekman” flow dominates dispersal of water.

On the Origin of Infragravity Waves
Seafloor pressure sensor data show that long-period ocean surface waves radiating from the world’s shorelines are mostly reflected back to shore by the continental shelf edge.
