The 13 C of organic matter bound within the crystal lattice of foraminiferal calcite tests may provide a potential tracer of the isotopic composition of the surface water primary photosynthate. Using 13 C of the organic matter extracted from the crystal lattice and the calcite test, it is theoretically possible to estimate the paleo-surface water pCO 2 . We have tailored this technique initially for the subpolar planktonic foraminifera species Globigerina bulloides . Initial surface water pCO 2 estimates from deep-sea core BOFS 5K (50°41.3'N, 21°51.9'W, water depth 3547 m) indicate that the northeast Atlantic Ocean may have been a greater sink for CO 2 during the last glacial than during the Holocene. Greatly reduced benthic foraminifera abundances, especially phytodetritus feeders, in BOFS 5K during the last glacial indicates low surface productivity. This rules out a productivity-driven CO 2 sink. The enhanced glacial CO 2 sink must, therefore, have results from a southwards shift of the centre of deep water formation.
