Our research raises questions about the future behaviour of East Antarctica, because surface meltwater is predicted to become increasingly important for Antarctic mass-loss as atmospheric temperatures rise. An excellent comment piece by Alexandra Boghosian discussing this can be viewed here:
East Antarctica slides into the spotlight as surface melt hotspot - Nature Climate Change
Ice-sheet surface melting impacts sea level and ice dynamics. Now two studies provide a wake-up call for monitoring melt in Antarctica.

We also find clear correlations between surface meltwater ponding and large-scale modes of climate variability, including links with the Southern Annular Mode in East Antarctica and the Amundsen Sea Low on the Antarctic Peninsula.

This increase in surface meltwater area in East Antarctica, without a corresponding increase in snow melt, indicates a potential shift in the ice sheet's surface properties, making it more prone to retaining meltwater in surface ponds.

In East Antarctica, we find that there has been a significant increase in the amount of surface meltwater ponding in recent years, with more variability from one year to the next.

We used Google Earth Engine to map surface meltwater at monthly intervals across the entire Antarctic Ice Sheet between 2006 – 2021 (totalling over 130,000 Landsat 8 images).
