Discovery of Hidden Atlantic Current Poses New Questions for Climate Models

Buzzline

Researchers from Utrecht University have uncovered that a crucial connection between the Agulhas Leakage and Atlantic circulation did not function as anticipated millions of years ago. The team analyzed sediments from the late Pliocene epoch, dated between 3.6 and 2.6 million years ago, including samples from a location approximately 500 kilometers south of South Africa. Notably, around 3.4 million years ago, this area experienced a temperature drop of about 3°C as the Agulhas Leakage nearly vanished, while the formation of North Atlantic Deep Water intensified. These results imply that the controls of the AMOC may vary with changes in climate and geography, providing significant insights for future oceanographic studies.

00:00Scientists have made a surprising discovery about a major Atlantic Ocean current.

00:04Researchers at Utrecht University studied ocean sediments dating back millions of years.

00:10They focused on the Agula's leakage near South Africa.

00:14About 3.4 million years ago, this flow of warm, salty water nearly disappeared.

00:20The region also cooled by roughly 3 degrees Celsius.

00:24Scientists expected the Atlantic circulation to weaken as a result.

00:27But the opposite happened.

00:30North Atlantic deep water formation actually became stronger.

00:33The finding challenges a long-standing theory about how the AMOC is maintained.

00:38Researchers say ocean circulation can respond differently as climate and geography change.

00:44The discovery could help scientists better understand.

00:47How the Atlantic circulation may respond to future climate changes.
