Fertilizing phytoplankton with volcanic ash
Description: On August 7, 2008, a stratovolcano in the Aleutian Islands began erupting just as a storm system was passing overhead. Over several days, the explosive eruption at Kasatochi Volcano sent ash and sulfur dioxide about 11,000 meters (35,000 feet) into the air and thousands of kilometers downwind. That iron-enriched ash spread out across a vast area of the North Pacific Ocean. Downwind from Kasatochi, the concentration of chlorophyll in the ocean increased by 150 percent.
