Abstract:

Here, we present ~160 kyr geochemical datasets from Ocean Discovery Program Site 202-1240 in the eastern equatorial Pacific to constrain paleoproductivity (Baxs flux) and BWO using a multiproxy approach (aU, Mn/Al, Δδ13C, and U/Ba). Quantitative records of bottom water oxygen (BWO) are critical for understanding deep ocean change through time. Because of the stoichiometric relationship between oxygen and carbon, BWO records provide insight into the physical and biogeochemical processes that control the air-sea partitioning of both gases with important implications for climate over Quaternary glacial-interglacial cycles.
