The rapid changes in the Southern Ocean and Antarctica highlight the urgency of better direct observations and measurements, beyond satellite monitoring and modelling.
If we want to live in a world with Emperor penguins, we need to cut emissions steeply and protect parts of the ocean around Antarctica where climate change will have the biggest impact.
Sea ice around Antarctica has always followed a predictable seasonal cycle. Now, we’ve experienced a sudden dramatic loss, and the changes are here to stay.
After several decades in research, including 22 years at the Australian Antarctic Division, this scientist is standing up for our icy continent. Here’s why Antarctic research needs ongoing funding.

Nel Law’s voyage to Antarctica and back, through the choppy waters of a longstanding marriage, is the story of a woman’s right to be, to change, to grow and to love.

More trouble in Antarctica: the extent of frozen seawater fastened to the coast (called landfast ice) hit a record low in March 2022. If this trend persists, the consequences could be catastrophic.
China and Russia have been blocking international plans to protect marine life in East Antarctica. Will next week’s special meeting in Chile break the deadlock? Australia hopes so.
The Weddell Sea helps power the great ocean conveyor, which moves heat, carbon dioxide and nutrients around Earth’s ocean basins.

It was the trip of a lifetime for an Australian research team studying moss in Antarctica. After two months at Casey Station they returned with great videos and loads of data for further analysis.
Scientists have detected a 30% slowdown of the deep ocean currents that form in Antarctica, with profound consequences for Earth’s climate, sea level and marine life.

The world’s oceans regulate our climate, but they are entering uncharted territory, with record surface warming and changes to Antarctica’s deep meltwater which drives global currents.
The rhythmic expansion and contraction of Antarctic sea ice is like a heartbeat. But there’s been a skip in the beat. Deeply concerned scientists have released a diagnosis for policy-makers.
The Drake Passage, seen from Antarctica, is one of the most turbulent ocean regions on Earth.

Working with underwater robots, scientists show how deep sea mountains and fast currents between Antarctica and South America play a crucial role in stabilizing the climate.
In a plot reminiscent of the 2004 movie The Day After Tomorrow?, Australian scientists are warning that the Southern Ocean’s deep “overturning” circulation is slowing and headed for collapse.
Unravelling the mystery of how life in Antarctica survived past ice ages involved sampling some of the oldest museum records. When combined with a dating database, a familiar story is revealed.
