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.

Onset of permanent stratification in the subarctic Pacific Ocean

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…

Glacial-interglacial variability in denitrification in the World's Oceans: Causes and consequences

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

[1] 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…
