Half a Century of Satellite Data Reveals Massive Polar Ice Loss

The most comprehensive assessment yet of changes in the world's polar ice sheets, led by researchers from Northumbria University and supported by NASA, combined evidence from 42 independent satellite surveys spanning more than five decades. The findings show that the two ice sheets lost an estimated 11,309 billion tonnes of ice between 1979 and 2023.

Investigating the Mackenzie Polynya - a Wind-Made Window in East Antarctica’s Sea Ice

The Mackenzie Polynya, an area of open water or thin ice that persists within the surrounding winter sea-ice pack, forms in Prydz Bay. Although they may appear to be small gaps in the Antarctic sea-ice cover, polynyas play an outsized role in the Southern Ocean system. They are major sites of sea-ice formation, contributing to the production of dense, cold water that helps drive global ocean circulation.

Keeping Watch Through Polar Winter: Autonomous Science at Princess Elisabeth Station

This annual seasonal transition highlights a growing trend in polar science: the increasing role of autonomous technologies in collecting data from regions where year-round human occupation is costly and difficult. Instruments left behind can continue monitoring atmospheric conditions, glaciological processes and other environmental variables long after field teams have returned home.

Giant Fan-Shaped Structure Discovered Beneath East Antarctica’s Ice

A vast geological structure hidden beneath the East Antarctic Ice Sheet is offering scientists a new way to understand both Antarctica’s ancient past and the behaviour of its ice today. The findings may help explain events linked to the evolution of the supercontinent Gondwana and the eventual separation of Antarctica from Australia.
