The equatorial Pacific Ocean is one of the major high-nutrient, low-chlorophyll regions in the global ocean. In such regions, the consumption of the available macro-nutrients such as nitrate and phosphate is thought to be limited in part by the low abundance of the critical micro-nutrient iron. Greater atmospheric dust deposition could have fertilized the equatorial Pacific with iron during the last ice age—the Last Glacial Period (LGP)—but the effect of increased ice-age dust fluxes on primary… Expand
Productivity and sediment focusing in the Eastern Equatorial Pacific during the last 30,000 years
The Eastern Equatorial Pacific (EEP) affects the ocean-atmosphere exchange of CO_2 on seasonal and interannual time scales through a balance of upwelling of CO_2-rich waters and the drawdown of CO_2Expand
Regional patterns and temporal evolution of ocean iron fertilization and CO2 drawdown during the last glacial termination
Abstract The last time Earth's climate experienced geologically rapid global warming was associated with the last glacial termination, when atmospheric CO2 concentrations rose from 180 ppmv duringExpand

Changes in marine export productivity may have played a prominent role in the atmospheric CO2 rise and associated warming of the last deglaciation, via their impact on the air-sea partitioning ofExpand
The simulated climate of the Last Glacial Maximum and insights into the global marine carbon cycle
Abstract. The ocean's ability to store large quantities of carbon, combined with the millennial longevity over which this reservoir is overturned, has implicated the ocean as a key driver ofExpand
Recycled iron fuels new production in the eastern equatorial Pacific Ocean
Nitrate isotope measurements provide a new constraint on the controls of surface nitrate concentration in eastern equatorial Pacific surface waters and allow us to quantify the degree and temporal variability of nitrate consumption. Expand
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 explain this phenomenonExpand
Orbital and sea-level changes regulate the iron-associated sediment supplies from Papua New Guinea to the equatorial Pacific
Abstract Iron (Fe) supplied to the equatorial Pacific are thought to play a critical role in marine biogeochemical cycle and the related air–sea CO2 flux. Previous studies have shown that Papua NewExpand
Weak overturning circulation and high Southern Ocean nutrient utilization maximized glacial ocean carbon
Abstract Circulation changes have been suggested to play an important role in the sequestration of atmospheric CO2 in the glacial ocean. However, previous studies have resulted in contradictoryExpand
Nitrogen isotope evidence for expanded ocean suboxia in the early Cenozoic
The ocean was more suboxic and supported greater denitrification in the Paleocene than during the Oligocene, and changes in the nitrogen isotopic composition of marine organic matter correlate with the collision of India and Asia and the circulation changes that occurred as a result. Expand
Deglacial Si remobilisation from the deep-ocean reveals biogeochemical and physical controls on glacial atmospheric CO2 levels
Abstract During the last glacial period, the sluggish deep Ocean circulation sequestered carbon into the abyss leading to the lowering of atmospheric CO2. The impact of this redistribution onExpand


Iron Fertilization of the Subantarctic Ocean During the Last Ice Age
The isotopic composition of foraminifera-bound nitrogen in samples from an Ocean Drilling Project sediment core was investigated and found millennial-scale changes in nitrate consumption correlated with fluxes in the iron burial and productivity proxies over the past 160,000 years, which explains a significant part of the difference in atmospheric CO2 concentrations observed to occur across glacial cycles.

Export fluxes of calcite in the eastern equatorial Pacific from the Last Glacial Maximum to present
[1] The eastern equatorial Pacific (EEP) is an important center of biological productivity, generating significant organic carbon and calcite fluxes to the deep ocean. We reconstructed paleocalciteExpand
Enhanced carbon pump inferred from relaxation of nutrient limitation in the glacial ocean
This study suggests the paradoxical decline in opal accumulation rate in the glacial EEP results from a decrease in the silicon to carbon uptake ratio of diatoms under conditions of increased iron availability from enhanced dust input, and supports the idea of an invigorated biological pump during the last glacial period that could have contributed to glacial carbon dioxide drawdown.

Sedimentary nitrogen isotopic ratio as a recorder for surface ocean nitrate utilization
In two contrasting regions of the ocean, the equatorial Pacific and the southern ocean, the δ15N of core top sediments were strongly related to [NO3−] in surface waters. With distance from theExpand
Nitrogen isotopic evidence for deglacial changes in nutrient supply in the eastern equatorial Pacific
[1] The Eastern Equatorial Pacific (EEP) is a high nutrient–low chlorophyll region of the ocean. Downcore nitrogen isotope records from the EEP have been previously interpreted as a direct reflectionExpand
