Summary: | The dataset compiles reconstructed changes in deep-water oxygen concentration for the past 1.5 Ma using stable carbon isotope measurements of benthic foraminifer: the epibenthic Cibicidoidies wuellerstorfi and the infaunal Globobulimina affinis, obtained from the International Ocean Discovery Program (IODP) Site 339-U1385 along the Iberian Margin (Northeast Atlantic; 2578 mbsl). The dataset covers the Middle Pleistocene Transition (MPT) and has a mean sampling frequency of ~290 yrs. Changes in North Atlantic deep-water oxygenation for the past 1.5 Ma reveal a significant (>40 µmol/kg) reduction in glacial deep-water oxygen concentration at ~960 ka suggesting increased storage of respired carbon, which is consistent with a drawdown of glacial atmospheric pCO2 values. The dataset includes the following records obtained from the IODP Site 339-U1385: reconstructed oxygen concentration and stable isotope measurements for the past 1.5 Ma; paired sample data focussed on the MIS 27-21 interval including ... |
