Trends in Antarctic Ice Sheet Elevation and Mass [PDF]
Geophysical Research Letters, 2019 AbstractFluctuations in Antarctic Ice Sheet elevation and mass occur over a variety of time scales, owing to changes in snowfall and ice flow. Here we disentangle these signals by combining 25 years of satellite radar altimeter observations and a regional climate model.

Solid Earth change and the evolution of the Antarctic Ice Sheet [PDF]
Nature Communications, 2019 The evolution of the Antarctic Ice Sheet is driven by a combination of climate forcing and non-climatic feedbacks. In this review, the authors focus on feedbacks between the Antarctic Ice Sheet and the solid Earth, and the role of these feedbacks in ...

Future climate response to Antarctic Ice Sheet melt caused by anthropogenic warming. [PDF]
Sci Adv, 2020 Antarctic ice loss over the next 250 years will affect global climate, influencing warming rates and ice sheet stability. Meltwater and ice discharge from a retreating Antarctic Ice Sheet could have important impacts on future global climate.

Four decades of Antarctic Ice Sheet mass balance from 1979-2017. [PDF]
Proc Natl Acad Sci U S A, 2019 Significance Statement We evaluate the state of the mass balance of the Antarctic Ice Sheet over the last four decades using a comprehensive, precise satellite record and output products from a regional atmospheric climate model to document its impact on

The uncertain future of the Antarctic Ice Sheet
Science, 2020 The Antarctic Ice Sheet is losing mass at an accelerating pace, and ice loss will likely continue over the coming decades and centuries. Some regions of the ice sheet may reach a tipping point, potentially leading to rates of sea level rise at least an order of magnitude larger than those observed now, owing to strong positive feedbacks in the ice ...

Investigating the internal structure of the Antarctic ice sheet: the utility of isochrones for spatiotemporal ice-sheet model calibration [PDF]
The Cryosphere, 2021 Ice-sheet models are a powerful tool to project the evolution of the Greenland and Antarctic ice sheets and thus their future contribution to global sea-level changes. Testing the ability of ice-sheet models to reproduce the ongoing and past evolution of

Economic impacts of melting of the Antarctic Ice Sheet [PDF]
Nature Communications, 2022 AbstractMelting of the Antarctic Ice Sheet (AIS) could contribute metres to global sea level rise (SLR) in the long run. We couple models of AIS melting due to rising temperatures, SLR, and economic impacts of SLR on coastlines worldwide. We report SLR projections close to the latest literature.

Observations of Buried Lake Drainage on the Antarctic Ice Sheet. [PDF]
Geophys Res Lett, 2020 Between 1992 and 2017, the Antarctic Ice Sheet (AIS) lost ice equivalent to 7.6 ± 3.9 mm of sea level rise. AIS mass loss is mitigated by ice shelves that provide a buttress by regulating ice flow from tributary glaciers.

Antarctic ice sheet response to sudden and sustained ice-shelf collapse (ABUMIP)
Journal of Glaciology, 2020 Antarctica's ice shelves modulate the grounded ice flow, and weakening of ice shelves due to climate forcing will decrease their ‘buttressing’ effect, causing a response in the grounded ice.

Widespread distribution of supraglacial lakes around the margin of the East Antarctic Ice Sheet. [PDF]
Sci Rep, 2019 Supraglacial lakes are important to ice sheet mass balance because their development and drainage has been linked to changes in ice flow velocity and ice shelf disintegration.
