The Antarctic ice sheet is nearly twice the area of Australia and holds enough freshwater to raise global sea levels by 58 metres.

Plastic debris in the sea hosts the plastisphere, a whole new microbial ecosystem.
The equivalent of four more years of global CO₂ emissions could soon be released into the atmosphere, exacerbating climate change.
Geologist Sharmaine Verhaert explains her search for the origins of pink sand found on beaches near Adelaide on The Conversation Weekly.
The Southern Ocean’s krill-rich waters attract multiple species of filter-feeding whales – and, increasingly, fishing boats.
New research shows how marine debris from continents across the southern hemisphere threatens Antarctica’s remote coastline and unique marine ecosystems. Foreign organisms might be hitching a ride.
Antarctica’s riskiest glacier is a disaster in slow motion, a polar scientist writes. But in a rare bit of good news, the worst-case scenario may be off the table.
In the barren cold deserts of ice-free Antarctica only lichen, mosses and algae survive – for now.
Something extraordinary is happening above Antarctica, and it might bring unusual weather to the southern hemisphere for months to come.
The southern lights have inspired artists for more then 200 years. Here are some of the best examples from across the decades.
The scientific and broader community must join together to advance Southern Ocean science and protect this vital natural asset.
In some of the most remote places on Earth, tags attached to seals collect data at the cutting edge of ocean science.
Few observations exist from before the 2002 Larsen B Ice Shelf collapse. We’ve now estimated how many billions of tons of glacier ice were lost – and what it means for the future.
Howling winds take sea salt from the Southern Ocean and lay it down in Antarctica as snow, then ice. Hidden in these ice cores is a warning about Australian fire seasons.
Women play a critical role in fieldwork in the Arctic and Antarctica, but the vast majority of them report negative experiences while undertaking this research. Here’s how we can fix the problem.
As in modern society, food, air quality and exercise were seen as key to good health – and the expedition’s success.
Migratory birds could bring the lethal bird flu variant that is assailing the rest of the world’s birds.
Iron-rich dust feeds phytoplankton. They are a key form of life in the Southern Ocean, which acts as a climate shock absorber.
When landslides or glaciers bring rocks to the surface, cosmic rays bombard them, smashing common atoms into rarer forms and acting as a chronometer of the changing Earth.
Four years of persistent ozone holes have sparked concern about what more UV is doing to Antarctic ecosystems.
