Abrupt changes are developing across Antarctica’s ice, ocean and biological systems; some of these changes are intensifying faster than equivalent Arctic changes, potentially irreversibly, and their i...

The vast ice of Antarctica has long seemed impregnable. But sudden changes are arriving – from shrinking sea ice to melting ice sheets and slowing ocean currents.

Background There has been ever-growing research fitting movement models to marine mammal satellite tracking data in recent years, yet little focus on methods attempting to go beyond individual restric...

Sulfur isotope excursions in skeletal collagen samples from Eurasia suggest rapidly changing biogeochemical processes across the region from about 30,000 to 15,000 years ago, potentially related to ch...

Extensive flat surfaces observed beneath the East Antarctic Ice Sheet margin were formed by fluvial erosion and have modulated the ice-sheet response to climate change, according to an analysis of rad...

Abstract. Antarctic sea ice plays many crucial roles in the physical environments and ecosystems of Antarctica and the Southern Ocean. In this study, we sy

The polar sea-ice zones are highly productive and seasonal habitats that support large populations of vertebrate predators. In the Antarctic, snow petrels (Pagodroma nivea) are regarded as highly ice-...

Greenland-wide observations of crevasse volume and distribution suggest substantial increases in crevassing between 2016 and 2021 at marine-terminating sectors with accelerating ice flow.
