DOI: 10.1029/2020gl092060
Abstract: Mass balance assessments of the East Antarctic ice sheet (EAIS) are highly sensitive to changes in firn thickness, causing substantial disagreement in estimates of its contribution to sea‐level. To better constrain the uncertainty in recent… read more here.

DOI: 10.1038/nature25026
Abstract: Antarctica’s continental-scale ice sheets have evolved over the past 50 million years. However, the dearth of ice-proximal geological records limits our understanding of past East Antarctic Ice Sheet (EAIS) behaviour and thus our ability to evaluate… read more here.

DOI: 10.1038/nclimate3180
Abstract: Surface melt has been tied to the collapse of Antarctic Peninsula ice shelves. This study illustrates that warmer temperatures associated with katabatic winds drive similar processes in an East Antarctic ice shelf, highlighting vulnerability to… read more here.

DOI: 10.3389/fmicb.2020.01165
Abstract: Antarctic cryoconite holes (CHs) are mostly perennially ice-lidded and sediment-filled depressions that constitute important features on glaciers and ice sheets. Once being hydrologically connected, these microbially dominated mini-ecosystems provide nutrients and biota for downstream environments.… read more here.
