Multidecadal satellite observations indicate that the Antarctic Ice Sheet (AIS) is losing mass
at an accelerating rate, which has the potential to impact many aspects of the climate …

Revisiting interior water mass responses to surface forcing changes and the subsequent effects on overturning in the Southern Ocean

JE Tesdal, GA MacGilchrist, RL Beadling… - Journal of …, 2023 - Wiley Online Library
Two coupled climate models, differing primarily in horizontal resolution and treatment of
mesoscale eddies, were used to assess the impact of perturbations in wind stress and …
