news from inside and outside the oil patches." Boufadel said the researchers currently believe that micro-organisms, which would typically consume the oil, may play a key role in the oil's lack of biodegradation along the beaches. Boufadel hypothesizes that the microorganisms, which live in the water and need other nutrients to be able to consume the oil, may not be getting enough nitrogen, phosphorus or oxygen in order to do that. Or, he adds, a layer or sort of "skin" may have developed around the oil patches, making them impenetrable by the micro-organisms. Boufadel also believes that environmental factors such as temperature could be inhibiting the micro-organisms. "There may be enough nutrients, but the temperature may be so low that these microorganisms cannot grow fast enough to consume the oil that lingers on these particular beaches," he said. As part of the Prince William Sound study, the research team will be using a numerical model developed by Boufadel to account simultaneously for all the factors causing the lack of biodegradation.
