How old is the oldest ice in Antarctica?

Antarctica is so cold that snowfall builds up year after year, resulting in frozen blankets of ice more than 3 km thick in places. You might think that to find the oldest ice, one simply has to dig ever deeper, to find samples ...

Dramatic decline in Adélie penguins near Mawson

Long-term monitoring has revealed a 43% decline in a large Adélie penguin population off the East Antarctic coast, near Mawson research station, over the past decade.

Antarctic glaciers vulnerable to rising temperatures

On the East Antarctic Plateau there are huge glaciers under the sea. In order to improve future scenarios related to rising sea levels, scientists need to understand the ways in which these glaciers will respond to rising ...

Scientists expose vulnerabilities of critical Antarctic ice shelf

Pine Island Ice Shelf in West Antarctica, which holds back enough ice to raise sea levels by 0.5 meters, could be more vulnerable to complete disintegration than previously thought. A new study led by British Antarctic Survey ...

Are we missing a crucial component of sea-level rise?

Recent efforts using computational modeling to understand how melting ice in Antarctica will impact the planet's oceans have focused on ice-sheet geometry, fracture, and surface melting—processes that could potentially ...
