Study finds craters come from forceful releases of methane gas from underground ponds as temperatures warm

Methane explosions. Another alarming positive feedback mechanism. The warmer it becomes in the Siberian tundra, the more likely that underground frozen methane hydrates will destabilize, and release large amounts of methane into the atmosphere.

Undersea ‘fire-ice’ is vulnerable to leaking greenhouse gas, finds new study.

Buried beneath the oceans surrounding continents is a naturally occurring frozen form of methane and water. Sometimes dubbed “fire-ice” as you can literally set light to it, marine methane hydrate can melt as the climate warms, uncontrollably releasing methane – a potent greenhouse gas – into the ocean and possibly the atmosphere. Colleagues and I have just published research showing more of this methane hydrate is vulnerable to warming than previously thought. This is a worry as that hydrate contains about as much carbon as all of the remaining oil and gas on Earth. Releasing it from the seabed could cause the oceans to become more acidic and the climate to warm further. This is a dangerous set of circumstances. The massive venting of methane from similar ancient marine hydrate reservoirs has been linked to some of the severest and most rapid climate changes in the Earth’s history. There is even evidence that the process has started again near the east coast of the US. I have worked on hydrates for over a decade, mainly looking at the methane hydrate offshore of Mauritania, West Africa. Recently I have taken 3D seismic data intended to reveal oil and gas and repurposed it to map out the hydrates under the ocean floor. Ultimately, I wanted to work out if climate change is causing methane to bubble to the surface. 3D seismic is the geologist’s equivalent of the doctor’s CT scan. It can cover hundreds of square kilometres, and can reveal hydrates a few kilometres below the seabed. Hydrate is easily identified in these giant surveys because the sound waves created by a source of seismic energy towed by a ship reflect off the bottom of the hydrate layers.

An introduction to Methane Hydrates

:D 최근에 좀 재미있게 읽은 기사가 버뮤다 삼각지대가 사실은 심해에 매장된 대규모 메탄 하이드레이트(메탄 가스 즉 천연가스가 심해의 낮은 온도 때문에 얼려진채 심해 바다 표면에 붙어 있는 형태)가 해저 지진이나 여러 이유로 기체화하면서 마침 근처를 지나가던 배를 뒤집거나 예상 못한 화재 등을 일으켜 침몰시켰다는 설인데 상당히 그럴듯 합니다

참고로 한반도와 일본 사이는 메탄하이드레이트 매장량이 이미 상당하다는게 탐사 결과 나온 상태지요 물론 심해탐사가 원체 비용이 많이 들고 제대로 된 경제성 있는 채굴 기술도 아직도 미국, 일본 등지에서 연구중이지요

Woah.

There's a weird type of 'ice' found in the ocean that burns when exposed to a flame - and scientists think they've finally solved the mystery of how this strange substance forms under the sea.

Gas hydrates, also known as 'flammable ice', are formed as gas gets trapped in lattices of water molecules - and it really does look a lot like strange, pockmarked ice.

This flammable ice is widely found inside minerals packed into clay-rich ocean sediments. The things is, the saltiness and pore size inside those minerals shouldn't be conducive to the formation of gas hydrates - and that's been puzzling experts until now.

That moment when your worst nightmare comes true

I hate to say this more than you hate to hear it, but we’re on borrowed time. And while I’m not trying to scare anyone (least of all myself), shit just got more real, particularly for those living in the Pacific Northwest. (more…)
