δ13C and δ18O isotopes of Globigerina bulloides from ODP Site 177-1090

Over the last deglaciation there were two transient intervals of pronounced atmospheric CO2 rise; Heinrich Stadial 1 (17.5-15 kyr) and the Younger Dryas (12.9-11.5 kyr). Leading hypotheses accounting for the increased accumulation of CO2 in the atmosphere at these times invoke deep ocean carbon being released from the Southern Ocean and an associated decline in the global efficiency of the biological carbon pump. From core ODP1090 we present new G. bulloidies carbon and oxygen isotope records. These stable isotopic analyses were performed on a Thermo Finnigan MAT253 coupled with a Kiel IV carbonate device at the University of Southampton.
