“A scientific critique of oceanic iron fertilization as a climate change mitigation strategy”. Greenpeace Research Laboratories. September 2007 – “It is also likely that commercial-scale iron fertilization would be prohibitively expensive because of the cost of the large-scale monitoring programs which would be needed in order to trace and verify the amount of carbon sequestered, as well as to monitor for any negative impacts such as nitrous oxide formation, de-oxygenation or ecological changes.”
