Crozier (see above) and colleague Monty Graham at the Dauphin Island Sea Lab, Alabama, have identified a zone of low oxygen emerging off the Alabama shore that is kilely due to oil. Sampling.... showed reduced numbers and types of animals in the ares, suggesting mobile animals are leaving tha area. Plankton in the low oxygen zone appeared dead, Graham said.

This is the first time the dispersants have been used underwater in a spill response.
"I think that was terribly ill-advised," Crozier said. "It's keeping the oil unseen and very difficult to find and impossible, ultimately, to clean up."

Mitchelmore (see above) said, "Dispersant use has always been full of uncertainties. A lot ot these were identified in (a report) in 1989," she continued. "What is the point of doing these reports and finding these data gaps if no one ever looks at them?"
