The first-ever broad review of Antarctic ‘landfast’ ice highlights its far-reaching importance in the Earth system while documenting a recent dramatic crash in its extent.

Polar scientists are calling for an urgent intensification of national and international research and observational capabilities in view of rapid Arctic and Antarctic change.

Researchers have found that the deep ocean circulation around parts of Antarctica has slowed by 30 per cent since the 1990s, reducing oxygen levels across the world’s deep seas.

Is this sudden shift in the Southern Ocean a response to climate change? We need to know how the Antarctic system is changing – and why.

Using Artificial Intelligence to better simulate the amount of energy from the sun that strikes the Southern Ocean.

Sea-ice researchers join forces to release a science briefing for policy makers.

Not only do tiny phytoplankton have a big impact on clouds, they also play a crucial role in the climate system

Through the Million Year Ice Core project, Tasmania is gaining an entirely new climate research capability at the Institute for Marine and Antarctic Studies in Hobart.

What does Antarctic ice, Southern Ocean algal blooms, Australia’s active volcanoes and a particle accelerator have in common?

With three very extreme events of Antarctic sea ice loss in the last six years, it appears a regime shift is under way in the Southern Ocean.
