Dead Zones

This video is not currently available. We apologize for any inconvenience.

For almost 6 weeks a huge section of the Oregon coast turned deadly. A catastrophic drop in the oxygen levels of the water resulted in what scientists call a dead zone. Overpopulation caused a massive die off of microscopic algae in this area. Algae corpses sucked up all of the oxygen in the water and kicked off a domino effect. Scientists use modern technology to determine what exactly caused the algae to multiply in the first place.
