Synchronous deglacial thermocline and deep-water ventilation in the eastern equatorial Pacific.

The deep ocean is most likely the primary source of the radiocarbon-depleted CO released to the atmosphere during the last deglaciation. While there are well-documented millennial scale ΔC changes during the most recent deglaciation, most marine records lack the resolution needed to identify more rapid ventilation events. Furthermore, potential age model problems with marine ΔC records may obscure our understanding of the phase relationship between inter-ocean ventilation changes.
