A frequently quoted estimate of the global methane hydrate resource is 20,000 trillion cubic meters, or about 700,000 trillion cubic feet.

Released from the pressures of the ocean depths, methane hydrate expands to create huge volumes of methane gas, one of the most powerful of the greenhouse gases.

These are connected to melting of methane hydrate, an ice - like substance that forms, and is stable, under the sea floor in cold temperatures and under high pressure.

The timing is coincident with a period of global warming, and Williscroft and colleagues suggest that it was this warming that released methane frozen as methane hydrates in the sea floor, as a relatively sudden methane «burp.»

Here in Oregon we are the somewhat unwitting hosts of a great deal of methane hydrate research by Oregon State University, some Texas university people (and backing by the good old Houston - based gas industry), of deposits on and near the ocean floor on the Gorda Ridge just off our coast, which is a consequence of the subduction zone geomorphology of the area.

The Department of Energy received $ 5 million for methane hydrate research and development in fiscal year 2011; an experimental well on Alaska's North Slope, dubbed Ignik Sikumi (Inuit for «fire in the ice»), will go into production in 2012.

Many theories have been presented for the cause of the extinction, including plate tectonics, an impact event, a supernova, extreme volcanism, the release of frozen methane hydrate from the ocean beds to cause a greenhouse effect, or some combination of factors.

Trapped in ocean sediments near continents lie ancient reservoirs of methane called methane hydrates.

And this is Alvia Gaskill, whose name is attached to that report on methane hydrate release mitigation.

Furthermore, seismic activity has been proven to locally destabilize subsea methane hydrates at many sites around the world.

This finding further confirms crustal motions that could destabilize methane hydrates contained in the permafrost.

The zone where methane hydrate remained stable now shrank.

Given the vastness of the world's marine methane hydrate deposits — more than twice the carbon reserves of all other fossil fuels combined — it's not surprising that government agencies and the petroleum and natural gas industries have long been interested in harvesting this new energy supply.

There is a precise curve of temperatures and pressures that define the depth at which methane hydrates exist.

For example, methane hydrates along the United States outer continental shelf could provide more than 20 times its existing natural gas reserves.

The Goddard temperature data implies that by 24 Dec 2023 (within 71 months), the entire atmospheric system will be totally controlled by massive Arctic methane eruptions and massive extinctions will dominate worldwide.

But having made my point, I probably shouldn't hijack this interesting post about methane hydrates any further — I guess we should try to work out how to extract and burn them to avert the peak oil crisis risk of release: --RRB-

BP's initial attempts this week have been confounded, the company says, by a build - up of methane hydrate crystals blocking the relief pipe.

These new projects, managed by the Energy Department's National Energy Technology Laboratory, will focus research on field programs for deepwater hydrate characterization, the response of methane hydrate systems to changing climates, and advances in the understanding of gas - hydrate - bearing deposits.

Dr. Archer has worked on the ongoing mystery of the low atmospheric CO2 concentration during glacial time 20,000 years ago, and on the fate of fossil fuel CO2 on geologic time scales in the future, and its impact on future ice age cycles, ocean methane hydrate decomposition, and coral reefs.

He says that even if methane hydrates were resting beneath the Antarctic Ice Sheet, and they became destabilized and started bubbling methane up through the seawater to the surface, it would take hundreds of years for these methane reserves to have a detectable impact on global climate.

As countries produce more conventional and unconventional fuels, the planet is warming in areas where methane hydrates exist.

This glowing ledge showed that the mound contained methane hydrate, a lattice of frozen water that traps methane gas molecules within its icy cages.

Smaller but still large methane hydrate amounts below shallow waters as in the Arctic Ocean are more vulnerable; the methane may oxidize to CO2 in the water, but it will still add to the long - term burden of CO2 in the carbon cycle.

«How methane hydrates behave can have a big impact on safety, environmental issues and climate change.»
