The program uses an [H.sub.2]O+NaCl+C[O.sub.2] system (based on [T.sub.mClath], [T.sub.mIce]) and assumes an XC[O.sub.2] = 1 composition for vapor step (According to the Raman spectroscopy analysis) as well as a volume estimation of each phase after melting of clathrates.
If we persist in continuously adding more and more greenhouse gas to the atmosphere, we will, at some point, reach Arctic temperatures that will cause thousands of square miles of permafrost and shallow clathrates to thaw.
"We didn't expect that our study of clathrates in the Enceladus ocean would lead us to the idea that methane is actively being produced by hydrothermal processes," said lead author Alexis Bouquet, a graduate student at the University of Texas at San Antonio.
The less the dissociation pressure [P.sub.dissociation] of the simple hydrate of the mixture component, the higher its concentration in the clathrate phase.
Gas hydrates are solid crystalline compounds, in which gas molecules are lodged within the clathrate crystal lattice [8].
This fact supports the former hypothesis (Glinski et al., 1995) regarding the existence of clathrates at the interface.
Gas clathrate hydrates are inclusion compounds formed of
Warming ocean water to a depth of 3000 meters, [up arrow] resulting in release of seabed methane-bearing temperature clathrates as amplifying feedback of climate [right arrow] change.
In recent years, there have also been concerns about possible methane emission increases from melting of frozen sub-soil (permafrost) in the Arctic and ancient methane hydrates (solidified methane concentrate, also known as 'clathrates') underground and in the deep oceans.
As understanding and awareness of how current energy use affects local, regional and global environment and politics, the need for more renewable and sustainable energy supplies and greater energy-use efficiency becomes increasingly apparent, even though huge fossil resources remain -- especially as coal but also as oil sands, oil shales, methane clathrates and other unconventional sources (Rogner 1997).
Pelagic fisheries, seabed minerals, and methane clathrates may also prove interesting.
Their concept involved the promotion by the anaesthetics of quasi-spherical assemblies or "clathrates"--akin to Buckminster-Fullerine ("Bucky-Balls")--which are comprised of water molecules held together by hydrogen bonds.
