A 0.6 Million Year Record of Millennial-Scale Climate Variability in the Tropics

A ~600 kyr long scanning X-ray fluorescence record of redox variability from the Cariaco Basin, Venezuela, provides insight into rapid climate change in the tropics over the past five glacial-interglacial cycles. Variations in the sediment accumulation of the redox-sensitive element molybdenum (Mo) can be linked to changes in Intertropical Convergence Zone migration and reveal that millennial-scale variability is a persistent feature of tropical climate over the past 600 kyr, including during periods of interglacial warmth. This geochemical record supports the idea that high-frequency tropical climate variability is not controlled solely by ice volume changes, with implications for the role of high-latitude forcing of Intertropical Convergence Zone position and tropical hydrology on millennial timescales.
STUDY NOTES: This file contains the depth-age points used to construct the chronology for the spliced MD03-2622/ODP Hole 1002C scanning XRF record, the planktonic d18O record from ODP Hole 1002C, and the sedimentary Mo Scanning-XRF record from the spliced cores.
