[1] Increasing oceanic productivity by fertilizing nutrient-rich regions with iron has been proposed as a mechanism to offset anthropogenic emissions of carbon dioxide. Earlier studies examined the impact of large-scale fertilization of vast reaches of the ocean for long periods of time. We use an ocean general circulation model to consider more realistic scenarios involving fertilizing small regions (a few hundred kilometers on a side) for limited periods of time (of order 1 month). A century… Expand
Effect of natural iron fertilization on carbon sequestration in the Southern Ocean
TLDR
It is found that a large phytoplankton bloom over the Kerguelen plateau in the Southern Ocean was sustained by the supply of iron and major nutrients to surface waters from iron-rich deep water below, suggesting that changes in iron supply from below may have a more significant effect on atmospheric carbon dioxide concentrations than previously thought.

Efficiency of small scale carbon mitigation by patch iron fertilization
Abstract. While nutrient depletion scenarios have long shown that the high-latitude High Nutrient Low Chlorophyll (HNLC) regions are the most effective for sequestering atmospheric carbon dioxide,Expand
Model simulations of carbon sequestration in the northwest Pacific by patch fertilization
Iron fertilization of nutrient-rich surface waters of the ocean is one possible way to help slow the rising levels of atmospheric CO2 by sequestering it in the oceans via biological carbon export.Expand
Impact of atmospheric and terrestrial CO2 feedbacks on fertilization-induced marine carbon uptake
The sensitivity of oceanic CO2 uptake to alterations in the marine biological carbon pump, such as brought about by natural or purposeful ocean fertilization, has repeatedly been investigated byExpand
Side effects and accounting aspects of hypothetical large-scale Southern Ocean iron fertilization
Abstract. Recent suggestions to slow down the increase in atmospheric carbon dioxide have included ocean fertilization by addition of the micronutrient iron to Southern Ocean surface waters, where aExpand
The impact on atmospheric CO 2 of iron fertilization induced changes in the ocean's biological pump
Abstract. Using numerical simulations, we quantify the impact of changes in the ocean's biological pump on the air-sea balance of CO2 by fertilizing a small surface patch in the high-nutrient,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
Ocean Fertilization for Sequestration of Carbon Dioxide from the Atmosphere
The ocean is a major sink for both preindustrial and anthropogenic carbon dioxide. Both physically and biogeochemically driven pumps, termed the solubility and biological pump, respectively Fig.5.1)Expand

TLDR
It is demonstrated that iron supply controls phytoplankton growth and community composition during summer in these polar Southern Ocean waters, but the fate of algal carbon remains unknown and depends on the interplay between the processes controlling export, remineralisation and timescales of water mass subduction.
