Feedback mechanisms controlling Antarctic glacial-cycle dynamics simulated with a coupled ice sheet–solid Earth model

T Albrecht, M Bagge, V Klemann - The Cryosphere, 2024 - tc.copernicus.org
The dynamics of the ice sheets on glacial timescales are highly controlled by interactions
with the solid Earth, ie, the glacial isostatic adjustment (GIA). Particularly at marine ice …
