Driving down Highway 23 last week in the southern Louisiana fishing town of Port Sulphur (map), David Ojeda could smell that something wasn't right. Turbulent winds over the approaching Gulf of Mexico oil spill were blowing strong odors inland, the 68-year-old shrimper suspects.
"Everybody's worried," he said Wednesday at the Port Sulphur harbor, which was filled to capacity with fishers rendered idle by the spill. "Nobody knows what will happen."
Unpleasant though it may be for those on the shore, that smell could be a sign of Mother Nature doing her own dirty work: It's the pungent scent of evaporating surface oil, which rises into the atmosphere and gets broken down by sunlight.
The joint federal-industry response team, led by U.S. Coast Guard Rear Adm. Mary Landry, has been attacking the growing slick with an arsenal of chemical dispersants, protective booms, and containment domes on the seafloor, among other techniques.
At the same time, the environment has been doing its own cleanup, which should not be ignored, experts say.
