Gas
Hydrate is an ice-like crystalline solid formed
from a mixture of water and natural gas, usually methane. They occur in the
pore spaces of sediments, and may form cements, nodes or layers.
Gas
Hydrate is found in sub-oceanic sediments in the polar regions (shallow water)
and in continental slope sediments (deep water), where pressure and temperature
conditions combine to make it stable.
Natural
Gas Hydrate contains highly concentrated methane, which is important both as
an energy resource and as a factor in global climate change.
Gas
Hydrate can be studied in the laboratory, where a machine is used to create
the proper pressure and temperature conditions for hydrate formation, or it
can be studied in situ using seismic data collected aboard ships and geophysical
models.
Currently,
groups of scientists in the U.S., Canada, Norway, Great Britain and Japan are
working to try to understand gas hydrate and the role it plays in the global
climate and the future of fuels.
Does
loss of gas from gas hydrate account for extensive ship-sinkings in the "Bermuda
Triangle"
