Research Abstract

We reconstructed the atmospheric convection activity in the tropical Pacific by analyzing biomarkers in marine cores retrieved from five locations in the tropical Pacific. Paleotemperature records demonstrated that the cold tongue shrunk, the western Pacific warm pool expanded, and zonal temperature gradient was relaxed during the last deglaciation. A deuterium record of fatty acids from the southern South China Sea disagrees with a published stalagmite record from northern Borneo. The latter is consistent with paleotemperature records, suggesting that zonal temperature gradient and the position of convection center has varied in response to precession.
