Tiny dips in sea level reveal flow of climate-regulating underwater waterfalls

Polar Journal AG Team

Satellite data reveals tiny sea level dips that mark underwater waterfalls – cold, dense water plunging off Antarctica’s continental shelf. These flows help regulate Earth’s climate but are weakening as the planet warms.

Antarctica’s hidden threat: meltwater under the ice sheet amplifies sea-level rise

Polar Journal AG Team

A new study shows how subglacial water could threaten the stability of the Antarctic ice cap. Which could add more than two metres than currently estimated to global sea levels by 2300.

Rafts of garbage, kelp and other debris could transport alien invaders to a warming Antarctica

The remote icy wilderness at the bottom of the world is exposed to pollution and foreign organisms on floating ocean debris.

Floating robots reveal just how much airborne dust fertilises the Southern Ocean – a key climate ‘shock absorber’

Guest Author

The Southern Ocean, a region critical to Earth’s climate, hosts vast blooms of microscopic ocean plants known as phytoplankton. They form the very basis of the Antarctic food web.

Has Antarctic sea ice lost its connection to the atmosphere?

Julia Hager

Sea ice cover in the Southern Ocean has remained well below the long-term average practically since the beginning of this year, leading scientists to conclude that Antarctic sea ice has entered a new state.
