It wasn't until I went out on a lake in the winter when the ice had frozen that I learned a lot about methane bubbles. narrator: The ice traps gases bubbling up from the decomposing permafrost.

Scientists have released images of a methane "fountain" found "violently boiling" beneath an Arctic sea in Siberia. Photos taken on-board the Akademik Mstislav Keldysh research vessel in the East ...

"So you're flash thawing the permafrost under these lakes. And we have very easily measured ancient greenhouse gases coming out." Methane bubbles up from the thawed permafrost at the bottom of the ...

They measured the air and found it contained 200 times more methane and 20 times more ... a serious reason to be concerned if gas bubbles appear in the permafrost zone.” The researchers worry ...

but I realized that this method of measuring methane has to work, if we’re going to understand what was in those bubbles. And what I started to see was that in these lakes, where permafrost was ...

Arctic permafrost is already thawing ... together plastic floats that I could place on the lakes to capture bubbles of methane. I dropped the traps by leaning over the side of abandoned boats ...

When permafrost thaws into soft soil ... Watch the full video of the bouncy methane bubbles below: Read next BI Tech Memo ...

Elsewhere, scientists cast a wary eye toward clouds of methane bubbles roiling the waters of the Siberian continental shelf. Those emissions, possibly from subsurface permafrost, are even harder ...

When permafrost thaws, methane-producing microbes—known as methanogens—kick into action. They consume the carbon-rich material and belch out methane gas, which can bubble up through lakes and ...

Thawing permafrost forms thermokarst lakes ... in a press release from NASA. Methane bubbles appear on the surface of Big Trail Lake. (NASA/Sofie Bates) There are such high levels of methane ...

It's notably the process that's thought to lead to thermokarsts, lakes that appear in areas where permafrost is melting, which bubble with methane and can be lit on fire. But that doesn't explain ...
