Supercharged El Niño Could Speed Up Southern Ocean Warming

by Erin Martin-Jones 24 March 202324 April 2023

Projected changes to El Niño will likely accelerate warming of the deep oceans around the Antarctic, supplying heat that could drive ice loss and sea level rise.

Gulf Stream Closes the Valve of the Labrador Current

by Takeyoshi Nagai 17 March 202316 March 2023

Virtual particles released in the Labrador Current revealed that the westward penetration of the current into the shelf seas is inhibited by warm core rings emanating from the Gulf Stream.
