For example, permafrost--thick subsurface layer of soil that remains frozen year-round--and frozen methane deposits in the seabed, known as methane hydrates or clathrates
, are critically important parts of the cryosphere and hence the climate system.
0 mm, lanceolate to linear-lanceolate, brown to light brown, lustrous, not clathrate
, not bullate, adaxially very sparsely glandular, densely pubescent, sparsely scaly, the glands ca.
As the Arctic Ocean warms, it is melting the permafrost layer and methane clathrate
The TBAB CHS is comprised of fine solid particles (TBAB clathrate
hydrate crystal) and its aqueous solution.
Key words: clathrate
hydrate; database; gas hydrate; markup language; thermophysical properties; web access.
The weak radial and concentric sculpture differs from the strongly clathrate
sculpture of Neolepetopsis; the shell interior is opaque, rather than partially transparent.
is an icelike material itself in which water molecules form ``cages'' that have gas molecules trapped in them, in this case methane or natural gas.
It may show "unique promise as part of ice or clathrate
energy storage systems," they concluded, but it has "not yet been possible to confidently determine several economic matters.
3 mm, dark brown, spreading, narrowly lanceolate, sparsely denticulate, not clathrate
, not bullate, adaxially eglandular, sparsely pubescent, scales absent, the hairs 1.
To examine the composition of gas in the clathrate
phase of the samples, synthesized hydrates were decomposed under the temperature of 278 K and pressure of 0.
If this is so, methane might be released from its clathrate
cages during the eruptions of proposed 'cryovolcanoes' of water-ammonia slurry, or more simply could slowly seep out through fractures in the crust.
All of the cages are not necessarily dependent on the temperature and the pressure of the guest compound in equilibrium with clathrate
