When Winds and Currents Align, Ocean Mixing Goes Deep
Slantwise convection in the Irminger Sea off Greenland appears to mix ocean water to deeper depths than previously thought, representing an important contribution to Atlantic overturning.

How do Bob and Tom Eddies Meet, Pair-Spin, and Twist?
Autonomous float data reveal that mergers of two eddies, known to have spiraling subducting water surrounding each other, happens more frequently than previously thought.

Two Kinds of Warm Core Rings Emanate From the Gulf Stream
A new study reveals that long-lived warm core rings found in the “Ring Corridor”, a narrow path north of the Gulf Stream, have two different formation mechanisms.

Ocean Waves Cause Drag Coefficient Asymmetry Within Typhoons
Observations show that, due to ocean waves, the drag coefficients for surface wind stresses have spatial asymmetry within typhoons, which should be considered in weather and climate simulations.

Melting Below the Pine Island Ice Shelf Minds the Gap
New research shows that increased calving from West Antarctica’s Pine Island Ice Shelf will likely drive increased circulation of warm water—and melting—below the ice.

Capturing Ocean Turbulence at the Underbelly of Sea Ice
A specially designed instrument enabled researchers in the Arctic to measure turbulence within 1 meter of the interface where ice meets ocean.
