The Other Methane Bomb: Undersea Hydrates
December 3, 2010
Last spring, a study published in Science and led by the University of Alaska’s International Arctic Research Centre and the Russian Academy of Sciences, found that the frozen cap that scientists previously assumed would keep undersea methane trapped for many decades, or centuries, has been perforated. In the video above, lead author, Natalia Shakhova explains some of the findings. Methane Hydrates are huge potential sources of greenhouse feedback, and may have been the mechanism behind the Paleocene-Eocene Thermal maximum (PETM), a warming event of 55 million years ago which many scientists say is close parallel to our current situation in the paleo record.
Since we’ve had several posts on methane this week, it’s a good opportunity to learn more. I found a useful lecture, from Miriam Kastner, speaking at the Scipps Institute – after the jump…
finally, here’s some great eye candy from the University of Bremen, that gives a little more background, and some spacy undersea music.
