230Th Normalization: New Insights on an Essential Tool for Quantifying Sedimentary Fluxes in the Modern and Quaternary Ocean
Abstract 230Th normalization is a valuable paleoceanographic tool for reconstructing high‐
resolution sediment fluxes during the late Pleistocene (last~ 500,000 years). As its …

Deep‐sea oxygen depletion and ocean carbon sequestration during the last ice age
Enhanced ocean carbon storage during the Pleistocene ice ages lowered atmospheric CO2
concentrations by 80 to 100 ppm relative to interglacial levels. Leading hypotheses to …

Marine sedimentary uranium to barium ratios as a potential quantitative proxy for Pleistocene bottom water oxygen concentrations
Oxygen is essential for marine ecosystems, and it is linked by respiration to carbon storage
in the deep ocean. Reconstructing oxygen concentrations in the past has been limited by the …

Productivity patterns in the equatorial Pacific over the last 30,000 years
The equatorial Pacific traverses a number of productivity regimes, from the highly productive
coastal upwelling along Peru to the near gyre‐like productivity lows along the international …

Trace element (Mn, Zn, Ni, V) and authigenic uranium (aU) geochemistry reveal sedimentary redox history on the Juan de Fuca Ridge, North Pacific Ocean
Abstract Changes in meridional overturning circulation and water mass chemistry can be
recorded by oxygen concentrations in the deep ocean. Because the deep Pacific is the …
