- Abstract:
- We have previously developed a record of past atmospheric 14C concentrations (delta 14C) spanning the interval 45-10 ka from a Bahamas speleothem. The purpose of this new research is to improve resolution and continuity of this record, and to confirm the timing and magnitude of the dramatic shifts in delta 14C which are evident. The possible association of changes in delta 14C with changes in the strength and location of deep ocean ventilation (particularly NADW) will be investigated by derivation of a subtropical climate proxy record (delta 13C, delta 18O and trace element composition of calcite) for the same well dated speleothems. Carbon cycle modelling will be used to constrain the possible rates, duration and amplitude of climate and ocean change, and also potential geomagnetic or cosmic ray flux events.
