A research team led by The Australian National University (ANU) has found the first proof that Antarctica is not isolated from the rest of the Earth, with the discovery that foreign kelp had drifted 20,000 kilometres before surfing to the continent’s icy shores.
Scientists had previously thought that Antarctic plants and animals were distinct from others around the world because they were isolated, but this new research indicates that these differences are almost entirely due to environmental extremes rather than isolation.
The kelp’s journey is the longest known biological rafting event ever recorded and has helped the team re-evaluate the science of ocean drift that is used to track plastics, aeroplane crash debris and other floating material across our seas…
