"Methane hydrates are
solids which lock methane gas up under pressure in an ice-like lattice of water molecules.
They are present under the oceans and permafrost in vast quantities. In the offshore
Arctic, the cold allows their formation at sufficiently shallow depths that warming can
reach them and destabilize them. "

"Fuel on the Ocean Floor: Frozen Methane
Possible Energy Source
By Nick Wadhams The Associated Press
W A S H I N G T O N, April 4 — Congress is initiating research into
a near-limitless energy source
- that has the potential of ending America’s dependency on
foreign fuels
- but could, if improperly used, cause devastating damage to the
environment.
The House by voice vote Monday approved $47.5 million over five years to study
methane hydrates, ice-like
crystals buried under the Arctic permafrost or beneath the ocean floor at water depths
greater than 1,640 feet. "

"METHANE HYDRATE ICE
A Possible Mechanism For Ice Age And Global Warming Cycles
By Stephen Dwyer
Recent discoveries about the existence of a vast band of
Methane Hydrate Ice along the world's continental Slopes, at approx. 500
meters depth, have revolutionized the theories of the Ice Age and Global Warming
Cycles.
The accumulation of Methane Ice leads to Ice Ages and the rapid melting
and effervescence of this ice and gas
leads to and equally rapid Global Warming."

"Historic global warming linked to methane release
By John Roach
An intense period of global warming about 55.5 million years ago has been
linked to a massive release of methane, an event
that killed many deep-sea species and enabled terrestrial animals to flourish, according
to an
article in today's issue of the journal Science."

"Exploration and Production Methane Hydrates
The Next Frontier in Fossil Fuels
Methane Hydrates are the most abundant natural form of clathrates - unique chemical
substances in which molecules of one material (in this case, water) form an open solid
lattice that encloses, without chemical bonding, appropriately-sized molecules of another
material (in this case, methane).
Recent investigations have revealed that the widespread occurrence of both methane and
water allows methane hydrates to accumulate virtually everywhere pressures and
temperatures are suitable.
As a result, evidence of hydrates are being discovered at relatively shallow depths
beneath arctic permafrost and within the fine-grained clastic sediments on the slopes and
rises of continental shelves all around the world.
Of critical importance is the growing realization that,
- not only is the amount of methane held in this reservoir huge,
- but the reservoir itself is in
constant flux, absorbing gas from below, releasing
gas above, and continually equilibrating to changes in pressure, temperature and
geochemical regimes.
The implications of this vast, dynamic, and previously unnoticed methane reservoir on the global carbon cycle, long-term climate, seafloor
stability, and global economics and energy policy, are only now being investigated."

"Fuel on the Ocean Floor: Frozen Methane Possible Energy Source

W A S H I N G T O N, April 4 — Congress is initiating research into

on foreign fuels but could, if improperly used, cause devastating damage to the

The House by voice vote Monday approved $47.5 million over five years to study

More Than Gas, Coal and Oil Scientists estimate that the methane trapped in the frozen
deposits has an energy potential equal to more than twice that of all other fossil fuels
combined.
The U.S. Geological Survey has put the value of gas hydrates in the United States at
320,000 trillion cubic feet of gas, some 200 times conventional natural gas resources and
reserves in the country.
“If only 1 percent of the methane hydrate resource could be made recoverable, the
United States could more than double its domestic natural gas resource base,” the
bill’s chief sponsor, Rep. Mike Doyle, D-Pa., said in a statement.
But Doyle added that research must also be done on the threat that hydrates pose as they
decompose into gas and water when they enter the atmosphere, possibly contributing to
greenhouse gas accumulations. Scientists writing in the journal Science last November said
they had evidence to support the theory that the release of frozen methane from the ocean
55 million years ago was responsible for an abrupt warming of the Earth that had a
devastating effect on deep-sea life. "
