Fertilizing the ocean with iron is this a viable way to help reduce carbon dioxide levels in the atmosphere ocean iron fertilization an argument for:. Iron fertilization is a possible solution to reverse the effects of ocean acidification scientists believe they can inject iron into the oceans to stimulate photosynthesis, the process by which organisms turn carbon dioxide into oxygen, in phytoplankton. Works cited can we get the ocean to absorb more co2 a possible way to fix the climateyoutube youtube, 20 jan 2010 web 12 mar 2013 .
Iron fertilization is the intentional introduction of iron to iron-poor areas of the ocean surface to stimulate phytoplankton production this is intended to enhance biological productivity and/or accelerate carbon dioxide (co2) sequestration from the atmosphere. Iron fertilization raises a lot of interesting questions the relationship between the carbon dioxide cycle and marine processes is complex, and so far science isn't clear on the long-term effects of altering it. In july of 2012, the haida salmon restoration corporation in conjunction with american businessman russ george, carried out an audacious and completely unauthorized ocean fertilization experiment approximately 100 tonnes of iron sulfate were spread across the surface of an ocean eddy, some 300.

Iron fertilization of the subantarctic ocean during the last ice age alfredo martínez-garcía,1 daniel m sigman,2 haojia ren,3 robert f anderson,4 marietta straub,1 david a hodell,5 samuel l jaccard,6 timothy i eglinton,1 gerald h haug1. Sequestering carbon in these parts of the global ocean via iron fertilization would require significant ecosystem change, trull's paper said mit's sallie penny chisholm, one of the world's top biological oceanographers, finds the idea of geo-engineering the earth's atmosphere through oceanic iron fertilization to be anathema. Ocean iron fertilization for co 2 sequestration jorge l sarmiento princeton university with contributions from rick slater, anand gnanadesikan, john dunne, and irina marinov also. Iron fertilization and tracer addition operations 9 ] iron sulfate dissolved in seawater was discharged into the ship's wake as described by coale et al . Ocean fertilization is a natural process, which happens when the physical forces of global winds, volcanoes or deep-sea upwellings transfer mineral nutrients, like iron, from the earth's crust into the ocean.
Ocean models as well as the strong correlation of the sediment core changes with the known changes in atmospheric co2 suggest that this iron fertilization of southern ocean plankton can explain roughly half of the co2 decline during peak ice ages. Continuous iron fertilization in the southern ocean however, since the southern ocean is a source for deep waters that re-emerge in the tropics, severe depletion of nutrients in the southern. However, ocean fertilization has also been used to describe the naturally increased supply of iron (and other nutrients) around islands in the southern ocean (blain et al, 2007, pollard et al, 2009, wolff et al, 2011. Fertilizing the ocean with iron woods hole oceanographic institution is the world's leading non-profit oceanographic research organization our mission is to explore and understand the ocean and to educate scientists, students, decision-makers, and the public. An article on friday about an unauthorized iron fertilization experiment in the pacific ocean misstated the year in which a sanctioned experiment that was analyzed in a recent journal article had.
As the dialogue around ocean iron fertilization shows, language can have a powerful effect on how international society responds to emerging environmental problems prior to 2007, firms used the iron hypothesis to argue that international society should legitimate the sale of credits from oif. Smith you said - there should be some legitimate and comprehensive studies done before fertilizing the ocean the haida nation experiment of dosing 100 tons of iron sulfate in 10,000 sq kms of ocean with a budget of about $ 2 million, is a legitimate and comprehensive study. A univ of sydney engineer has ruled ocean iron fertilization an uneconomical solution to carbon capture and storage despite its early promise ocean iron fertilization is a process that attempts to encourage phytoplankton growth in regions with unused nutrients and stores carbon away from the atmosphere. The process of iron fertilization has been proposed and tested on other occasions in the past kubiak said that the challenge was to gather precise data on the bloom's biological activities and measuring the amount of carbon dioxide that is eliminated. Iron fertilization of up to 40,000 square kilometers of ocean, are attempting to profit using a similar business model 16 the dire threats posed by climate change have inspired.
Fertilizing the ocean with iron iron is a crucial nutrient for plants and the second most abundant chemical element on earth, although the greatest portion by far is locked in the earth's core. Scientists plumbing the depths of the central equatorial pacific ocean have found ancient sediments suggesting that one proposed way to mitigate climate warming—fertilizing the oceans with iron. An international research team has published the results of an ocean iron fertilization experiment (eifex) carried out in 2004 in the current issue of the scientific journal nature. This species of diatom, corethron pennatum, bloomed during the iron fertilization credit: marina montresor, szn / alfred wegener institu some hope fertilizing tiny, floating plants in the ocean.
However, with one exception , eight of the nine subsequent coastal and open ocean fertilization experiments (some using iron, some nitrogen) failed to produced lasting effects or significant results (there is also evidence of disproportionate triggering of harmful planktonic blooms) clearly, the geoegineering technique needed serious refinement. Charles miller of oregon state university said that ocean fertilization could create a rise in iron-limited phytoplankton populations, which by dying and sinking would use enough oxygen to create extensive dead zones in the oceans.
