Geochemistry of Recent oxic and anoxic marine sediments: Implications for the geological record
The global carbon cycle: a test of our knowledge of earth as a system.
It is concluded that although natural processes can potentially slow the rate of increase in atmospheric CO2, there is no natural "savior" waiting to assimilate all the anthropogenically produced CO2 in the coming century.

The surface waters of the modern subarctic Pacific Ocean are isolated from the nutrient-rich waters below by a steep vertical gradient in salinity (halocline), a feature which is a dominant control…

The late Quaternary history of water-column denitrifcation of the eastern Pacific margins and the Arabian Sea is reconstructed using sedimentary δ15N measurements. The δ15N values in six piston cores…
Carbon dioxide release from the North Pacific abyss during the last deglaciation
Sedimentary geochemical records from sites spanning the deep subarctic Pacific are presented to show that a poorly ventilated water mass containing a high concentration of respired carbon dioxide occupied the North Pacific abyss during the Last Glacial Maximum, qualitatively consistent with hypotheses invoking a deglacial flushing of respiring carbon dioxide from an isolated, deep ocean reservoir.
Large changes in oceanic nutrient inventories from glacial to interglacial periods
CHANGES in ocean chemistry and circulation have been invoked to explain the lower atmospheric CO2 concentrations of glacial periods observed in ice-core records1. The processes that modulate these…

Nitrogen isotope and productivity variations along the northeast Pacific margin over the last 120 kyr: Surface and subsurface paleoceanography
 Glacial-interglacial changes in sedimentary δ15N over the last 120 kyr display a remarkably similar pattern in timing and amplitude in core records extending from the denitrification zone in the…
Intermittent existence of a southern Californian upwelling cell during submillennial climate change of the last 60 kyr
 Application of a high-resolution multiproxy approach to a sedimentary section drilled at Ocean Drilling Program Site 1017, located under a highly active upwelling cell off Point Conception,…
