Many oceanic properties are not directly observed but are instead estimated using proxy measurements. A new method uses physics-based correlations to reduce uncertainty in this relationship.

A Direct Bridge Between Tropical Cyclones and Ocean Eddies
Tropical cyclones can inject potential vorticity directly into ocean eddies—an alternative way for tropical cyclones to leave fingerprints on the ocean besides the traditional near-inertial wave.

Below the Great Pacific Garbage Patch: More Garbage
New research is finding there’s more to marine debris than just what appears near the ocean surface, including tons of microplastics extending hundreds of meters into the deep.

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.

Different El Niño, Different Paths of North Equatorial Current
Different types of El Niño have different impacts on the North Equatorial Current Bifurcation and can be extended to ocean circulations in the Pacific and the global climate system.

Larger Role for Shallow Intermediate Waters in Ocean Circulation
Water masses formed off southeastern Greenland may contribute more than previously thought to the variability of the Atlantic Meridional Overturning Circulation, which strongly influences global climate.

Different Eddy Transport for “Lazy” and “Athletic” Observers
Two specifications of fluid dynamics—taking measurements at a fixed point and following a fluid parcel—are compared for quantifying eddy transport in the ocean.
