Heterogeneous Basal Thermal Conditions Underpinning the Adélie-George V Coast, East Antarctica

Published in Geophysical Research Letters, 2024

This paper examines the vulnerability of East Antarctica’s Adélie-George V Land, focusing on the Wilkes Subglacial Basin, to ice sheet instability. Using a new statistical method to analyze airborne radar sounding data, the study identifies mixed frozen and thawed bed conditions near the grounding zone. These findings suggest that the region may be more susceptible to climate-driven retreat and mass loss than previously thought, due to the potential ease of ice flow over areas that are near thawing.

Ice mass loss sensitivity to the Antarctic ice sheet basal thermal state

Published in Nature Communications, 2022

In this paper, we examine how thawing at the base of the Antarctic ice sheet could lead to significant ice mass loss and contribute to sea-level rise, particularly in previously considered stable regions of East Antarctica. Using numerical model projections, the study highlights that areas like the Wilkes Basin could become major contributors to sea-level rise if basal thawing occurs, challenging the focus on West Antarctica.
