The scientists say they believe they are first to uncover observational evidence that frozen methane deposits in the Arctic Ocean have started to be released after determining that methane levels ...
In order for the clathrate hypothesis to be applicable to PETM, the oceans must show signs of having been warmer slightly before the carbon isotope excursion, because it would take some time for the methane to become mixed into the system and δ 13 C-reduced carbon to be returned to the deep ocean sedimentary record. Up until the 2000s, the ...
Direct evidence was obtained in 1995 when data from the Hubble Space Telescope and other observations suggested the existence of liquid methane on Titan, either in disconnected pockets or on the scale of satellite-wide oceans, similar to water on Earth. [5] The Cassini mission affirmed the former hypothesis, although not immediately.
Frozen methane bubbles from thawing permafrost. Large deposits of frozen methane, when thawing, release gas into the environment. [3] In cases of sub-sea permafrost, the methane gas may be dissolved in the seawater before reaching the surface; however, in a number of sites around the world, these methane chimneys release the gas directly into the atmosphere, contributing to global warming.

Methane clathrate block embedded in the sediment of hydrate ridge, off Oregon, USA. Clathrate hydrates, or gas hydrates, clathrates, or hydrates, are crystalline water-based solids physically resembling ice, in which small non-polar molecules (typically gases) or polar molecules with large hydrophobic moieties are trapped inside "cages" of hydrogen bonded, frozen water molecules.
Methane clathrate (CH 4 ·5.75H 2 O) or (4CH 4 ·23H 2 O), also called methane hydrate, hydromethane, methane ice, fire ice, natural gas hydrate, or gas hydrate, is a solid clathrate compound (more specifically, a clathrate hydrate) in which a large amount of methane is trapped within a crystal structure of water, forming a solid similar to ice.
A cold seep (sometimes called a cold vent) is an area of the ocean floor where seepage of fluids rich in hydrogen sulfide, methane, and other hydrocarbons occurs, often in the form of a brine pool. Cold does not mean that the temperature of the seepage is lower than that of the surrounding sea water; on the contrary, its temperature is often ...
