While everyone else worries about the toxicity of the oil, the physics of plume dispersion, and the costs to wildlife and workers across the gulf, one crew of scientists see a once-in-a-lifetime opportunity. The obvious ethical restrictions to releasing large amounts of methane (which contributes 25 times more greenhouse effect than carbon dioxide) into the ocean has complicated study of how seepage of natural gas at the ocean floor contributes to global warming. Their investigation could also help answer one of the questions everybody else is asking: just how much oil has been released?
