The paleoproductivity in the Southern Ocean plays a crucial role in controlling the atmospheric CO 2 concentration. Here, we present the sediment record of gravity core ANT37-C5/6-07, which was retrieved from the Cosmonaut Sea (CS), Indian Ocean sector of the Southern Ocean. We found that the change...
