Machine Learning Looks Anew at Isotope Ratios in Oceanic Basalts

by Paul Asimow 25 October 202224 October 2022

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.

Two Kinds of Warm Core Rings Emanate From the Gulf Stream

by Takeyoshi Nagai 12 October 202211 October 2022

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

by Lei Zhou 5 October 20224 October 2022

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

Sarah Derouin, Science Writer by Sarah Derouin 3 October 20223 October 2022

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.
