A volcanic plume of iron-laden ash from a 2008 Alaskan volcano eruption led to an unprecedentedly huge bloom of photosynthetic ocean plankton that fed off the ash, researchers have found.
This natural phenomenon is much like a geoengineering scenario proposed by some researchers who want to fight global warming by spurring the growth of marine plants that can suck carbon dioxide from the air.
However, this massive bloom of plankton resulted in only a modest uptake of atmospheric carbon dioxide, the researchers said, seemingly dealing another blow to such geoengineering schemes.

A secluded island in the Aleutian chain is revealing secrets of how land and marine ecosystems react to and recover from a catastrophic volcanic eruption that appeared at first glance to destroy all life on the island.
Yet little by little - a wingless beetle here, a tuft of grass there, Kasatochi, an island in the Alaska Maritime National Wildlife Refuge rarely studied by scientists before its Aug. 7, 2008, volcanic eruption, is showing signs of recovery.

The Alaska Volcano Observatory has issued a red alert for planes flying near the Kasatochi volcano in the Aleutian islands after it erupted explosively on the 7th August sending an ash plume more than 35,000 feet into the air, and forcing two biologists from the U.S. Fish and Wildlife Service to evacuate the island.
Three major explosive eruptions occured at Kasatochi between approximately 2230 UTC (14:30 AKDT) on 07 August and 0500 UTC on 08 August(2100 AKDT on 07 August). ash from these explosions reached at least 45,000 ft above sea level.

Kasatochi went from a quiet volcano to an explosive eruption within 24 hours and with very little warning
