Ocean iron fertilization?

Anyone else think this sounds like a bad idea?

On September 26-27, scientists at the Woods Hole Oceanographic Institution (WHOI) will host an international, interdisciplinary conference on the proposed “iron fertilization” of the ocean as a means to combat rising concentrations of greenhouse gases in the atmosphere.

Several times over the past century, scientists and environmental engineers have proposed spreading slurries of dissolved iron into the oceans in order to “fertilize” the waters and promote vast blooms of marine plants (phytoplankton). Phytoplankton consume carbon dioxide as they grow, and this growth can be stimulated in certain ocean basins by the addition of iron, a necessary micronutrient.

Of course, thats the point of the symposium, to look into the idea and see if its a bad idea. Still, I can’t get out of my head the image of uncontrolled algae growth strangling all life in the ocean. More information can be found here
