Methane gas depletes the marine oxygen levels, making it difficult for fish and other organisms to survive. One scientist says the methane gas concentration is at record levels. As a result of these toxins, scientists are now finding dead zones of life in the areas with oil contamination. If the spill cannot be stopped, then what happens?
"I've never seen concentrations of methane this high anywhere," said Dr. [Samantha] Joye (a senior marine scientist at the University of Georgia), who analyzed samples from a submerged oil plume that she said was 15 miles long, five miles wide and 300 feet thick. "The whole water column has less oxygen than it normally does."
But please note, that some Russian researchers believe that this dead zone may be caused by another oil spill separate and apart from the Deepwater Horizon. This whole situation is beyond crazy and unbelievable at this point.
Their water sampling also revealed an oil plume 142 miles southeast of the damaged well, but their laboratory analysis showed the oil was different chemically from that coming from the well. They didn't indicate what the source could be.Source: Wall Street Journal
