    Gulf oil full of methane, adding new concerns

    It is an overlooked danger in oil spill crisis: The crude gushing from the well contains vast amounts of natural gas that could pose a serious threat to the Gulf of Mexico’s fragile ecosystem.

    The oil emanating from the seafloor contains about 40 percent methane, compared with about 5 percent found in typical oil deposits, said John Kessler, a Texas A&M University oceanographer who is studying the impact of methane from the spill.

    That means huge quantities of methane have entered the Gulf, scientists say, potentially suffocating marine life and creating “dead zones” where oxygen is so depleted that nothing lives.

    “This is the most vigorous methane eruption in modern human history,” Kessler said.

    NEW ORLEANS — It is an overlooked danger in oil spill crisis: The crude gushing from the well contains vast amounts of natural gas that could pose a serious threat to the Gulf of Mexico's fragile ecosystem.

    The oil emanating from the seafloor contains about 40 percent methane, compared with about 5 percent found in typical oil deposits, said John Kessler, a Texas A&M University oceanographer who is studying the impact of methane from the spill.

    That means huge quantities of methane have entered the Gulf, scientists say, potentially suffocating marine life and creating "dead zones" where oxygen is so depleted that nothing lives.

    *****"This is the most vigorous methane eruption in modern human history," Kessler said.

    • pped - obviously the catch will be down since Fool-in-Chief Barry has banned fishing! That's a no brainer.

    • Unfortunately, the paper you cited deals only with spraying AFTER the oil gets to the sea surface. Since the dispersant is being injected directly into the oil stream at the well head, it gets into the oil immediately. This is a good thing.

    • pped - the dispersant is diluted so quickly that there is no way a fish will be exposed to that concentration for 4 days. Get a grip man!

    • issac - The paper only discusses spraying. If it discusses direct injection into the oil stream, tell me the page number. The bottom line from the paper is this.

      "One very obvious conclusion to be drawn from this work is that, when spills from offshore platforms
      threaten to contaminate nearby shorelines and when these spills can be effectively dispersed, there
      will be a net environmental benefit in almost every case. The reason for this is that the launch sites
      are well offshore. If a spill from one of these launch sites is to be effectively treated it must be fully
      treated within a few kilometers of the spill site. Here the spill still lies in deep offshore waters where
      environmental risks of chemical dispersion are small and considerably less than the risks posed by
      the untreated spill. The scenarios analyzed in this study showed that the size of the impact and the
      net environmental benefit from dispersant use will vary with spill conditions (spill location, season,
      type of spill). However, in all cases the net environmental benefit will favor dispersant use."

    • So, In your view, and if this is occuring, what's the end game?

    • "Here's the MMS PDF stating it

      http://www.slross.com/publications/mms/3..."


      This paper is discussing application of dispersant on the sea surface. BP are injecting dispersant directly into the oil stream at the source. Again, you really need to understand what you are reading here.

    • In my own experience, I have witnessed 'spontaneous combustion' caused by large piles of grass clippings. The methane gathers within the pile and heats to a temperature high enough to cause this. You can perform your own experiment with this, using a smaller pile of clippings. leave it for a few days and then check the temperature in the interior. (You can just plunge your hand deep into the middle and feel the heat.)

    • You guys are hopelessly ignorant.
