Fertilization of the ocean by adding iron compounds has induced diatom-dominated phytoplankton blooms accompanied by considerable carbon dioxide drawdown in the ocean surface layer. However, because the fate of bloom biomass could not be adequately resolved in these experiments, the timescales of carbon sequestration from the atmosphere are uncertain. Here we report the results of a five-week experiment carried out in the closed core of a vertically coherent, mesoscale eddy of the Antarctic… Expand
Biogeochemistry: The great iron dump
Multiple lines of evidence are presented that suggest carbon is exported to the deep ocean as a result of iron fertilization, with at least half of the bloom biomass sinking to below 1,000 metres. Expand
How deep is deep enough? Ocean iron fertilization and carbon sequestration in the Southern Ocean
Artificial ocean iron fertilization (OIF) enhances phytoplankton productivity and is being explored as a means of sequestering anthropogenic carbon within the deep ocean. To be considered successful,Expand
High particulate organic carbon export during the decline of a vast diatom bloom in the Atlantic sector of the Southern Ocean
Abstract Carbon fixation by phytoplankton plays a key role in the uptake of atmospheric CO2 in the Southern Ocean. Yet, it still remains unclear how efficiently the particulate organic carbon (POC)Expand
Ecosystem controls on carbon export efficiency from the naturally iron-fertilised phytoplankton bloom over the Kerguelen Plateau
In the ocean, the perpetual 'snowfall' of biogenic marine particles exports organic carbon from the well-lit surface layer to the deep sediments, promoting its sequestration. The efficiency of thisExpand
Factors Controlling the Lack of Phytoplankton Biomass in Naturally Iron Fertilized Waters Near Heard and McDonald Islands in the Southern Ocean
The Kerguelen Plateau is one of the regions in the Southern Ocean where spatially large algal blooms occur annually due to natural iron fertilization. The analysis of ocean colour data as well as inExpand
Sinking Diatom Assemblages as a Key Driver for Deep Carbon and Silicon Export in the Scotia Sea (Southern Ocean)
Physical and biogeochemical processes in the Southern Ocean are fundamental for modulating global climate. In this context, a process-based understanding of how Antarctic diatoms control primaryExpand
Thick-shelled, grazer-protected diatoms decouple ocean carbon and silicon cycles in the iron-limited Antarctic Circumpolar Current
It is suggested that large-scale iron fertilization of the silicate-rich Southern Ocean will not change silicon sequestration but will add carbon to the sinking silica flux, implying that thick-shelled, hence grazer-protected, diatom species evolved in response to heavy copepod grazing pressure in the presence of an abundant silicate supply. Expand
Iron fertilization enhanced net community production but not downward particle flux during the Southern Ocean iron fertilization experiment LOHAFEX
The data are consistent with the view that nitrate-rich but silicate-deficient waters are not poised for enhanced particle export upon iron addition, and attribute the lack of fertilization-induced export to silicon limitation of diatoms and reprocessing of sinking particles by detritus feeders.

Carbonate counter pump stimulated by natural iron fertilization in the Polar Frontal Zone
The production of organic carbon in the ocean’s surface and its subsequent downward export transfers carbon dioxide to the deep ocean. This CO2 drawdown is countered by the biological precipitationExpand
The biological pump is an important aspect of the global carbon cycle. Phytoplankton blooms in the surface ocean draw down atmospheric carbon dioxide and package it as organic particulates that sinkExpand


Southern Ocean deep-water carbon export enhanced by natural iron fertilization
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
Effect of natural iron fertilization on carbon sequestration in the Southern Ocean
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.

Extensive phytoplankton blooms in the Atlantic sector of the glacial Southern Ocean
[1] The sources and sinks of atmospheric carbon dioxide over glacial/interglacial cycles are under debate. Variation in productivity of the Antarctic Circumpolar Current (ACC) could potentially playExpand
Volcanic ash fuels anomalous plankton bloom in subarctic northeast Pacific
[1] Using multiple lines of evidence, we demonstrate that volcanic ash deposition in August 2008 initiated one of the largest phytoplankton blooms observed in the subarctic North Pacific. UnusuallyExpand
glacial-interglacial Co2 change : the iron hypothesis
Several explanations for the 200 to 280 ppm glacial/interglacial change in atmospheric CO2 concentrations deal with variations in southern ocean phytoplankton productivity and the related use orExpand
Mesoscale Iron Enrichment Experiments 1993-2005: Synthesis and Future Directions
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
Southern Ocean Iron Enrichment Experiment: Carbon Cycling in High- and Low-Si Waters
Two mesoscale experiments, designed to investigate the effects of iron enrichment in regions with high and low concentrations of silicic acid, were performed in the Southern Ocean, demonstrating iron's pivotal role in controlling carbon uptake and regulating atmospheric partial pressure of carbon dioxide.

Synthesis of iron fertilization experiments: From the iron age in the age of enlightenment
Comparison of eight iron experiments shows that maximum Chl a, the maximum DIC removal, and the overall DIC/Fe efficiency all scale inversely with depth of the wind mixed layer (WML) defining theExpand
Wind-Driven Upwelling in the Southern Ocean and the Deglacial Rise in Atmospheric CO2
It is shown that opal burial rates, and thus upwelling, were enhanced during the termination of the last ice age in each sector of the Southern Ocean, and directly link increased ventilation of deep water to the deglacial rise in atmospheric CO2. Expand
Role of Marine Biology in Glacial-Interglacial CO2 Cycles
Sedimentary records of marine productivity at the peak and the middle of the last glacial cycle are analyzed and show that neither changes in nutrient utilization in the Southern Ocean nor shifts in plankton dominance explain the CO2 drawdown. Expand
