The Latest Breaking News from Antarctic

Can next week's special meeting in Chile break the deadlock over East Antarctica's marine park proposal?

Amid the challenges of climate change, resource extraction and pollution, the survival of species and ecosystems depends on setting aside protected areas. But plans to establish marine protected areas in East Antarctica have stalled.

Antarctic tipping points: the irreversible changes to come if we fail to keep warming below 2℃

The slow-down of the Southern Ocean circulation, a dramatic drop in the extent of sea ice and unprecedented heatwaves are all raising concerns that Antarctica may be approaching tipping points.

Slowing deep Southern Ocean current may be linked to natural climate cycle – but that's no reason to stop worrying about melting Antarctic ice

Our new research in the Antarctic suggests that the vital layer of cold water on the sea bed, which circulates the globe and influences the ocean’s ability to continue absorbing much of the rise in atmospheric heat and greenhouse gas emissions, is heating up and shrinking.

Nine years after official pest-free status, Macquarie Island is recovering but it's a 'long game'

It's nine years since cats, rats, and rabbits were officially declared eradicated from sub-Antarctic Macquarie Island, but scientists fear a new threat is challenging its fragile ecosystem.

Deep ocean currents in Antarctica are slowing earlier than predicted

Antarctica drives a network of ocean currents that redistributes heat, carbon, and nutrients around the globe. There are signs this circulation is slowing down decades earlier than predicted, with profound consequences for the earth’s climate, sea level, and marine life.

Antarctic currents supplying 40% of world's deep ocean with nutrients and oxygen slowing dramatically

Deep ocean currents around Antarctica that are vital to marine life have slowed by 30% since the 1990s and could soon grind to a complete halt, a new study finds.

Antarctic alarm bells: observations reveal deep ocean currents are slowing earlier than predicted

Antarctica sets the stage for the world’s greatest waterfall. The action takes place beneath the surface of the ocean. Here, trillions of tonnes of cold, dense, oxygen-rich water cascade off the continental shelf and sink to great depths. This Antarctic “bottom water” then spreads north along the sea floor in…

Antarctic currents supplying 40% of world's deep ocean with nutrients and oxygen slowing dramatically

These deep ocean tides supply almost half of the world's oceans with vital nutrients and oxygen, but melting ice shelves are slowing them down.

Climate change slowing Antarctica's deep, dense waters

Scientists examining the impact of climate change in Antarctica say there has been a 30 per cent drop-off in deep water circulation since the 1990s.
