Machine Learning Looks Anew at Isotope Ratios in Oceanic Basalts
While past attempts to define isotopic endmembers and assign them a geodynamic significance ended in controversy, a machine-learning clustering algorithm offers a solution to this classical problem.
Tracing Anthropogenically Emitted Carbon Dioxide into the Ocean
Researchers labeled anthropogenically emitted carbon and tracked it with an ocean circulation model to determine whether it winds up in the sky or sea.
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.
Managing Mudslide Debris After Fires
California officials faced a conundrum in dealing with mudslides after the Thomas Fire.
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.
Internet Cable Reveals the Source of Underwater Vibrations
A novel use of an existing fiber-optic cable off the coast of Spain has clued scientists in to how seismic noise is generated in the ocean.
Tracking Climate Through Ship Exhaust
International regulations have reduced aerosol pollutants released from ships. Now, researchers want to use ship tracks to better understand the ambiguous effects that cleaner air has on climate.
