Measuring the environmental impact of Gulf oil spill

Last week’s vast oil spill just 50 miles into the Gulf of Mexico is already being called one of the most significant oil spills in U.S history. Yesterday, President Obama and the White House made it clear that they have moved cleanup efforts to the top of their priority list.

The spill is moving onshore and posing threats to a wide range of coastal life. For the latest we turn to Dave Cohen, news director for WWL Radio in New Orleans, and Chris Reddy, director of the Coastal Ocean Institute at Woods Hole Oceanographic Institution.
