Scientists have detected a 30 per cent slowdown of the deep ocean currents that form in Antarctica, with profound consequences for Earth’s climate, sea level and marine life.
UNSW researchers have solved the mystery of why and how ocean ‘hotspots’ are forming so fast, by examining the winds that influence the ocean currents heating these areas.

A new map of the world’s oceans redraws boundaries according to science, not geopolitics, and provides a crucial piece in the puzzle of who is creating marine dumping grounds, write Erik van Sebille and Gary Froyland.
The Southern Ocean is remote, fast moving and full of large eddies, so the missing aircraft will be increasingly difficult to locate if debris is not found soon, writes Erik van Sebille.
Oceanographic research at UNSW suggests the claimed lengthy voyage of a castaway fisherman could have occurred and he was lucky not to have ended up in the great garbage patch of the North Pacific.
