Oxygen depletion recorded in upper waters of the glacial Southern Ocean

Oxygen depletion in the ocean interior may be closely linked to atmospheric CO2level, yet robust proxies are scarce. Here, using foraminiferal I/Ca as a proxy for oxygenation changes, the authors show that oxygen depletion in the upper waters of the high latitude Southern Ocean occurred during glaci...

Description
Summary:Oxygen depletion in the ocean interior may be closely linked to atmospheric CO2level, yet robust proxies are scarce. Here, using foraminiferal I/Ca as a proxy for oxygenation changes, the authors show that oxygen depletion in the upper waters of the high latitude Southern Ocean occurred during glacials.
