Way to Dusty Death


When an iron fertilization experiment was performed in the southwest Atlantic in January 2009, scientists wanted to promote algal blooms for carbon sequestration. The experiment, using iron dust, was suspended due to environmental concerns. Results from similar experiments conducted in the sub-Arctic North Pacific Ocean suggest that this was probably for the best. The extra algae poisoned the water with a neurotoxin, domoic acid.
