What surprises me is the "the source of the ammonium and methane is most likely from the breakdown of organic matter that was deposited in the area hundreds of thousands of years ago when Antarctica was warmer and the sea inundated West Antarctica." part. If the methane was already readily available, why didn't the organisms multiply to use up the methane faster? I guess some organism breaks down the organic matter to methane and thereby limits the availability for the methane eating organism. But over the course of a hundred thousand years I feel that such a limited ecosystem should have exhausted the resources long ago. What is the limiting factor that prevents this?
I guess everything is really slow because of the cold temperature. It would be nice to have a comment from someone that knows about this type of ecosystem.
