Landfast Sea Ice: The Most Important Ice You’ve Never Heard Of

by Pat Wongpan and Alexander D. Fraser 22 August 202321 August 2023

Landfast sea ice, sea ice that is held stationary against the Antarctic continent, links firmly with many key climate processes, but its importance is only being fully realized as its extent dwindles.

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.
