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.
In 1898, a pioneering Antarctic expedition was stuck in sea ice for over a year. In 2024, that area is open water.
El Niño can direct more warm water to the base of West Antarctic ice shelves, accelerating melting and increasing global sea level.
There’s so much we still don’t know about whales. Here’s 3 amazing new things we’ve learnt about whales lately: how humpback whales have sex and give birth – and how baleen whales sing underwater.
The sub-zero area of Antarctica has shrunk by over 100km since the 1950s.
