11-14-11: A Better Bay?
Every summer, what’s known as a “dead zone” forms in the Chesapeake Bay – called “dead” because the amount of oxygen drops so low, fish and shellfish struggle to survive. This summer, the dead zone was one of the largest ever, reaching from the Bay Bridge to the Potomac River.
Yet, a new study conducted by researchers at the Johns Hopkins University and the University of Maryland’s Center for Environmental Science finds that efforts over the last 30 years to cut down on pollution to the Bay is actually reducing the overall size of the dead zone.
Sheilah discusses the results with the lead author of the study, Rebecca Murphy, a doctoral student in Johns Hopkins’ Department of Geography and Environment Engineering.
