Productivity-climate coupling recorded in Pleistocene sediments off Prydz Bay (East Antarctica)

Export-production in the Southern Ocean is thought to be tightly correlated with atmospheric CO2 fluctuations over geological times. Relevant studies are, however, mainly confined to the Atlantic and Pacific sectors of the Southern Ocean and often only cover the last glacial-interglacial cycle. Here, we present a sediment record retrieved off Prydz Bay (East Antarctica) spanning the last ~ 520 kyrs. We show that the distribution pattern of local...
