However, existing deep-sea [CO3 2-] \nreconstructions conflict with one another, complicating \npaleoceanographic interpretations. Here, we present deep-sea \n[CO3 2-] for five cores from the three major oceans quantified \nusing benthic foraminiferal boron/calcium ratios since the last \nglacial period. Combined benthic d13C and [CO3 2-] results \nindicate that deep-sea-released CO2 during the early deglacial \nperiod (17.5 to 14.5 thousand years ago) was preferentially \nstored in the atmosphere, whereas during the late deglacial \nperiod (14 to 10 thousand years ago), besides contributing to \nthe contemporary atmospheric CO2 rise, a substantial portion \nof CO2 released from oceans was absorbed by the terrestrial \nbiosphere. \n\n","author":null,"citation":"Yu, J., W.S.
