“Dead Zone”

May 2nd, 2008

From Smithsonian Magazine, April 2008:

Gasping for Breath
An ocean “dead zone” has been discovered off the Pacific Northwest. The water has so little oxygen that it “kills any marine animals that cannot swim or scuttle away,” says Jane Lubchenco of Oregon State University. She and her colleagues analyzed 60 years of data and found that oxygen levels dropped in 2002. Most of the hundreds of dead zones worldwide are caused by pollution. But this one was caused by winds and currents that disrupted the ecosystem and fueled oxygen-depleting bacteria.
