asks Russ George, chief scientist of the expedition as well as a controversial businessman with a history of attempting to start CO2 - removal schemes ranging from reforestation to ocean fertilization.

During her half - hour of interaction with the class, McNutt said, students asked questions ranging from the feasibility of the OTEC, or Ocean Thermal Energy Conversion — a strategy for harvesting energy from the oceans — to whether deforestation in Africa «might actually have a silver lining if it leads to ocean iron fertilization.&rOcean Thermal Energy Conversion — a strategy for harvesting energy from the oceans — to whether deforestation in Africa «might actually have a silver lining if it leads to ocean iron fertilization.&rocean iron fertilization.»

But he acknowledges that governments, wary of controversy, have shied away from funding further ocean fertilization projects, and he's skeptical of corporate efforts to support them, fearing a lack of scientific objectivity.

Possible mechanisms include (iv) fertilization of phytoplankton growth in the Southern Ocean by increased deposition of iron - containing dust from the atmosphere after being carried by winds from colder, drier continental areas, and a subsequent redistribution of limiting nutrients; (v) an increase in the whole ocean nutrient content (e.g., through input of material exposed on shelves or nitrogen fixation); and (vi) an increase in the ratio between carbon and other nutrients assimilated in organic material, resulting in a higher carbon export per unit of limiting nutrient expoOcean by increased deposition of iron - containing dust from the atmosphere after being carried by winds from colder, drier continental areas, and a subsequent redistribution of limiting nutrients; (v) an increase in the whole ocean nutrient content (e.g., through input of material exposed on shelves or nitrogen fixation); and (vi) an increase in the ratio between carbon and other nutrients assimilated in organic material, resulting in a higher carbon export per unit of limiting nutrient expoocean nutrient content (e.g., through input of material exposed on shelves or nitrogen fixation); and (vi) an increase in the ratio between carbon and other nutrients assimilated in organic material, resulting in a higher carbon export per unit of limiting nutrient exported.

From these relationships and reconstructed temperature time series, we diagnose glacial − interglacial time series of dust radiative forcing and iron fertilization of ocean biota, and use these time series to force Earth system model simulations.

Ocean fertilization is one strategy scientists are mulling to blunt the unrelenting growth in carbon dioxide emissions from smokestacks, tailpipes and deforestation.

Think of the baggage / luggage conveyer systems at airports, one blocked piece of lugguage affects & backs up the entire conveyer system, which offsets an even balance, like our oceans, from this iron fertilization!

From recent article «Iron fertilization enhanced net community production but not downward particle flux during the Southern Ocean iron fertilization experiment LOHAFEX», by P. Martin, M. Rutgers van der Loeff, N. Cassar, P. Vandromme, F. d'Ovidio, L. Stemmann, R. Rengarajan,... Continue reading →

EFFECT OF NATURAL IRON FERTILIZATION ON CARBON SEQUESTRATION IN THE SOUTHERN OCEAN Nature, Vol 446 26 April 2007 doi: 10.1038 / nature05700 The efficiency of fertilization, defined as the ratio of the carbon export to the amount of iron supplied, was at least ten times higher than previous estimates from short - term blooms induced by iron - addition experiments.

-- Southern Ocean Iron Fertilization Experiment (SOFeX)-- The basics of the most recent expedition — Penny Chisholm's site, which lists many professional papers — Paul Falkowski's article (PDF document)-- DOE article: Climate Change Scenarios Compel Studies of Ocean Carbon Storage — Government site for carbon sequestration research — An earlier piece Williams wrote on sequestration — Will Ocean Fertilization To Remove Carbon Dioxide from the Atmosphere Work?

In 2008, the United Nations Convention on Biological Diversity put in place a moratorium on all ocean - fertilization projects apart from small ones in coastal waters.

However, according to Professor Rosemary Rayfuse, an expert in International Law and the Law of the Sea at the University of New South Wales, Australia, who also attended the Woods Hole meeting, ocean fertilization projects are not currently approved under any carbon credit regulatory scheme and the sale of offsets or credits from ocean fertilization on the unregulated voluntary markets is basically nothing short of fraudulent.

This study closely follows a September Ocean Iron Fertilization symposium at the Woods Hole Oceanographic Institution (WHOI) attended by leading scientists, international lawyers, policy makers, and concerned representatives from government, business, academia and environmental organizations.

A second general method for cooling the planet involves removing carbon dioxide (CO2) from the atmosphere, either via sequestration or CO2 capture, or possibly through ocean iron fertilization to promote the growth of CO2 - consuming algae.

For iron fertilization forcing, we choose temperature − dust relationships from the high southern latitudes, as the Southern Ocean is the main region where this process is relevant.

Here we took a different approach by seeking and applying dust deposition observations from hotspots for dust radiative and iron fertilization forcing: NH subtropical latitudes and the Southern Ocean.

Olgun, N. et al.

Therefore it's my opinion that the not - so - extreme decline from April to July 2010, coupled with the higher - than - usual April value, coupled with the changes (both trend and fluctuation) in both the size of and the timing of the annual cycle, are such that there's insufficient evidence to conclude that the Eyjafjallajökull eruption caused a noticeable change in atmospheric CO2, whether by emissions from the eruption, the lack of emissions from air traffic, or iron fertilization of the oceans.

Like other plants, plankton uses the greenhouse gas carbon dioxide for photosynthesis; thus, theoretically, fertilization could have caused the ocean to take larger amounts of CO2 from the air, and entomb it in the ocean.
