Satellites can now track the deep ocean currents around Antarctica that could accelerate climate change.

L’Antarctique sera‑t‑il bientôt peuplé d’espèces exotiques à cause de nos déchets ?

Des débris et déchets marins menacent le littoral isolé de l'Antarctique et ses écosystèmes marins uniques. Car sur ces déchets peuvent se greffer des espèces étrangères à l'Antarctique.

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.

Torrents of Antarctic meltwater are slowing the currents that drive our vital ocean ‘overturning’ – and threaten its collapse

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.

Our team discovered clear changes in the distribution and strength of ocean eddies. These changes have never been detected before.

How an alien seaweed invasion spawned an Antarctic mystery

A chance discovery of some kelp that floated for 20,000km before washing up on an Antarctic beach has opened up a new chapter in our understanding of the currents that swirl around the Southern Ocean.
