Extended Data Fig. 8: Basal thermal state of the EAIS in George V Land and Adélie Land.
From: Extensive fluvial surfaces at the East Antarctic margin have modulated ice-sheet evolution
(a) Predicted basal thermal state along RES lines31. Colours represent the probability of the basal ice being frozen (0) or thawed (1); the map shown is an aggregate of four different combinations of labelling and radar processing31. White polygons mark the flat surfaces. (b) Predicted basal temperatures derived from simulations of the present-day Antarctic Ice Sheet generated using the Ice-sheet and Sea-level System Model (ISSM)32. Temperatures are divided into four bins: (i) at the pressure melting point (PMP), (ii) less than 2 °C below the PMP, (iii) between 2° and 5 °C below the PMP, and (iv) more than 5 °C below the PMP.
