This video shows a large plume of methane-rich gas continuously bubbling in a tundra lake in Alaska. In the background is a rubber raft used by researchers to explore field sites and collect data. Katey Walter Anthony made this recording in the summer of 2007.
In an explosive clip from the BBC's landmark series, scientists drill into a frozen lake to ignite methane gas that is trapped in bubbles beneath the surface. Do greenhouse gases pose a signficant threat to our planet? Dr Iain Stewart assesses the dangers.
Researchers at the University of Alaska Fairbanks are studying the East Siberian Arctic Shelf region and finding the seafloor there holds vast stores of frozen methane and is showing signs of instability and widespread venting of the powerful greenhouse gas. In this video University of Alaska Fairbanks scientist Natalia Shakhova discusses the East Siberian Arctic Shelf area.
