Arctic closure as a trigger for Atlantic overturning at the Eocene-Oligocene Transition

The authors show, using a paleoclimate model of the late Eocene, that a shift from Pacific to Atlantic overturning can be triggered at this time by closing the Arctic–Atlantic gateway.

A Warm, Stratified, and Restricted Labrador Sea Across the Middle Eocene and Its Climatic Optimum
- Environmental Science, GeographyPaleoceanography and paleoclimatology
- 2020
Two multiproxy reconstructions depict a consistent picture of relatively warm and fresh but also highly variable surface ocean conditions in the middle Eocene Labrador Sea, which implies either NADW did not yet form during themiddle Eocene or it formed in a different source region and subsequently bypassed the southern Labrador Sea.

It is concluded that the initiation of deep-water circulation from the Norwegian Sea into the North Atlantic Ocean took place much earlier than is currently assumed in most numerical models of ancient ocean circulation.
