Links between iron supply, marine productivity, sea surface temperature, and CO2 over the last 1.1 Ma

TL;DR: In this article, the authors present a new multiproxy data set of sea surface temperatures (SST), dust and iron supply, and marine export productivity from the marine sediment core PS2489-2/ODP Site 1090 located in the subantarctic Atlantic, that allow them to evaluate various hypotheses on the role of the Southern Ocean (SO) in modulating atmospheric CO2 concentrations back to 11 Ma.

Southern Ocean dust-climate couplings over the last 4,000,000 years
Alfredo Martínez-García,Antoni Rosell-Melé,Samuel L Jaccard,Walter Geibert,Daniel M. Sigman,Gerald H Haug +5 more
TL;DR: The extension of the record beyond the interval covered by the Antarctic ice cores reveals that, in contrast to the relatively gradual intensification of glacial cycles over the past three million years, Southern Ocean dust and iron flux rose sharply at the Mid-Pleistocene climatic transition around 1.25 million years ago.
