Short summary
We identified an ideal site in coastal East Antarctica for extracting ice core that contain detailed climate records dating back 20,000 years. We surveyed two ice rises combining radar measurements with ice flow modeling to assess their suitability. One site emerged as optimal, offering well-preserved climate history with high temporal resolution. An ice core record from this site could help us understand historical interactions between sea ice, winds, and precipitation patterns in the region.

The ice sheets covering Antarctica have built up over millenia through successive snowfall events which become buried and preserved as internal surfaces of equal age detectable with ice-penetrating radar. This paper describes an international initiative to work together on this archival data to build a comprehensive 3-D picture of how old the ice is everywhere across Antarctica, and how this will be used to reconstruct past and predict future ice and climate behaviour.

Short summary
The net accumulation of snow over Antarctica is key for assessing current and future sea-level rise. Ice cores record a noisy snowfall signal to verify model simulations. We find that ice core net snowfall is biased to lower values for ice rises and the Dome Fuji site (Antarctica), while the relative uncertainty in measuring snowfall increases rapidly with distance away from the ice core sites at the ice rises but not at Dome Fuji. Spatial variation in snowfall must therefore be considered.

This paper presents the release of over 60 years of ice thickness, bed elevation, and surface elevation data acquired over Antarctica by the international community. These data are a crucial component of the Antarctic Bedmap initiative which aims to produce a new map and datasets of Antarctic ice thickness and bed topography for the international glaciology and geophysical community.

Short summary
The evolution of the Antarctic ice sheets depends, in addition to factors representing the warming climate, on the earth structure beneath the ice. What’s beneath the ice is largely inaccessible for direct sampling, but can be interpreted with the use of satellite or airborne measurements. We apply an unsupervised machine learning method to such data in East Antarctica to test whether this can ease interpretation and hence our understanding of what rocks are beneath the ice.

Short summary
Lakes can form beneath the large ice sheets and can influence ice-sheet dynamics and stability. Some of these subglacial lakes are active, meaning that they periodically drain and refill. Here we report seven new active subglacial lakes close to the Antarctic Ice Sheet margin using satellite measurements of ice surface height changes in a region where little was known previously. These findings improve our understanding of subglacial hydrology and will help refine subglacial hydrological models.

Here, we study the effects of short–term atmospheric warming events on the ice sheet surface and subsurface temperatures of coastal Dronning Maud Land during 2014–2018. Our results revealed that the impact of warming events over ice sheet surface and subsurface temperatures varies with the mechanism of warming and prevailing meteorological conditions. The frequency and duration of such events are important for the surface and sub-surface processes of ice sheets.

Episodic Antarctic Ice Sheet Surface Warming events can affect the mass balance of ice sheets by sublimation and melting during summer. Our study using five-year borehole thermistor measurements revealed two types of events over the coastal Dronning Maud Land region: cloud-induced and wind-induced. Understanding the frequency and duration of these events is important for predicting their future impacts on ice shelves and ice sheets.

Short summary
Ice rises are locally grounded features surrounded by ice shelves. They help to stabilize the Antarctic Ice Sheet and in turn are affected by ice-sheet evolution. However, details of these influences depend on the glaciological settings of the ice rises. We first present detailed ground-based investigations from Blåskimen Island ice rise in East Antarctica. We found that the ice rise is at least ~ 600-years old and has been thickening by ~ 0.3 m per year over the past decade.
