Abstract

The boron isotope pH proxy in sediment-core planktic foraminifera is used as a tracer of oceanic CO2 outgassing to show that surface waters which derive partly from deep water upwelled in the Southern Ocean became a significant source of carbon to the atmosphere during the last deglaciation.
