Ocean iron fertilization has been proposed as a method to mitigate anthropogenic climate change, and there is continued commercial interest in using iron fertilization to generate carbon credits. It has been further speculated that ocean iron fertilization could help mitigate ocean acidification. Here, using a global ocean carbon cycle model, we performed idealized ocean iron fertilization simulations to place an upper bound on the effect of iron fertilization on atmospheric CO2 and ocean… Expand

  • 2012
TLDR
If solar radiation management were to be the main policy response to counteract global warming, ocean acidification would continue to be driven by increases in atmospheric CO2, although with additional temperature-related effects on CO2 and CaCO3 solubility and terrestrial carbon sequestration.

Iron fertilisation and century-scale effects of open ocean dissolution of olivine in a simulated CO2 removal experiment
Carbon dioxide removal (CDR) approaches are efforts to reduce the atmospheric CO2 concentration. Here we use a marine carbon cycle model to investigate the effects of one CDR technique: the open… Expand
A Review of Ocean Acidification and America's Response
TLDR
The effects of ocean acidification are examined and why they should help guide decisionmakers in setting CO2 emissions goals. Expand
Response of ocean acidification to a gradual increase and decrease of atmospheric CO2
We perform coupled climate–carbon cycle model simulations to examine changes in ocean acidity in response to idealized change of atmospheric CO2. Atmospheric CO2 increases at a rate of 1% per year to… Expand

Southern Ocean deep-water carbon export enhanced by natural iron fertilization
TLDR
Data from the CROZEX experiment in the Southern Ocean is reported to test the hypothesis that the observed north–south gradient in phytoplankton concentrations in the vicinity of the Crozet Islands is induced by natural iron fertilization that results in enhanced organic carbon flux to the deep ocean. Expand
Climate change, ocean processes and ocean iron fertilization
TLDR
Increased remineralization associated with the increased downward export of organic carbon particles would result in increased production of the third most important long-lived greenhouse gas, N2O, the magnitude of this effect is poorly known. Expand

TLDR
The findings of these 12 FeAXs reveal that iron supply exerts controls on the dynamics of plankton blooms, which in turn affect the biogeochemical cycles of carbon, nitrogen, silicon, and sulfur and ultimately influence the Earth climate system. Expand
