Open Ocean Iron Fertilization for Scientific Study and Carbon Sequestration
The trace element iron has been recently shown to play a critical role in nutrient utilization, phytoplankton growth and therefore the uptake of carbon dioxide from the surface waters of the global ocean. Carbon fixation in the surface waters, via phytoplankton growth, shifts the ocean/atmosphere exchange equilibrium for carbon dioxide. As a result, levels of atmospheric carbon dioxide (a green...
متن کاملEfficiency of small scale carbon mitigation by patch iron fertilization
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, recent simulations with prognostic biogeochemical models have suggested that only a fraction of the potential drawdown can be realized. We use a global ocean biogeochemical general circulation model developed a...
متن کاملIron fertilization in the ocean and consequences for the global carbon cycle
It has been suggested that fertilizing the ocean with iron can stop the continuing increase of atmospheric carbon dioxide by enhancing the biological uptake of carbon. This would decrease the surface ocean partial pressure of carbon dioxide, thus forcing the absorbtion of carbon dioxide from the atmosphere. Using a five-box model of the ocean circulation, we study the response of the ocean due ...
متن کاملArsenic removal by iron-modified activated carbon.
Iron-impregnated activated carbons have been found to be very effective in arsenic removal. Oxyanionic arsenic species such as arsenate and arsenite adsorb at the iron oxyhydroxide surface by forming complexes with the surface sites. Our goal has been to load as much iron within the carbon pores as possible while also rendering as much of the iron to be available for sorbing arsenic. Surface ox...
