Les paysages glacés et reculés de l’Antarctique sont de plus en plus pollués mais aussi exposés à des espèces étrangères dérivant jusqu’à ce bout du monde via des débris océaniques flottants. Conscients de cette menace qui pèse sur ce littoral isolé et les écosystèmes marins uniques de l’Antarctique, nous avons voulu savoir d’où venaient tous ces débris. Il s’avère qu’ils voyagent plus loin qu’on ne le pense.

The remote icy wilderness at the bottom of the world is exposed to pollution and foreign organisms on floating ocean debris. Recognizing the threat to Antarctica’s remote coastline and unique marine ecosystems, we wanted to find out where this material is coming from. It turns out it’s travelling further than you might think.

Previously, rafts reaching Antarctic waters have been genetically tested to reveal their source location. These analyses confirmed kelp could drift from sub-Antarctic islands including South Georgia and the Kerguelen Islands. But not all objects can be tested this way, and only a small fraction of the Antarctic coastline is visited by scientists each year. Scaling up such an approach to determine all possible source locations is not feasible. Instead, we turned to ocean modelling.
