In May 2017 a group of researchers led by the University of Texas at Austin Jackson School of Geosciences took to the Gulf of Mexico to retrieve samples of methane hydrate, a potential future...
6 Σεπ 2016 · Methane hydrate: fire, ice, energy. Found near the ocean floor and beneath Arctic permafrost, methane hydrate is a mysterious icy substance that burns when lit and holds vast amounts of potential energy.
2 Ιουν 2017 · Abstract. Widespread methane release from thawing Arctic gas hydrates is a major concern, yet the processes, sources, and fluxes involved remain unconstrained. We present geophysical data documenting a cluster of kilometer-wide craters and mounds from the Barents Sea floor associated with large-scale methane expulsion.
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.
22 Αυγ 2019 · We then discuss the five major types of gas hydrate occurrences, which includes Type-1: regionally disseminated low-concentration hydrate in muddy sediments, Type-2: fracture-filling hydrate at nonvent sites, Type-3: enriched hydrate at the base of hydrate stability zone in muddy sediments, Type-4: concentrated hydrate at vent sites, and Type-5 ...
7 Φεβ 2019 · Watch Video Part 2 (Duration: 1:28) In this video, Ruppel discusses newly described areas in the Barents Sea where pockmarks have been discovered on the sea floor. These may be indications of methane releases from deposits that formed under an ice sheet that covered the area during the glacial maximum.
25 Σεπ 2020 · Natural gas hydrates encase predominantly methane, but also higher hydrocarbons as well as CO 2 and H 2 S. Depending on the source of the feed gas, the amount of additional gases besides methane varies from less than 1 mol% to more than 40 mol% (Kvenvolden and Lorenson 2001; Lu et al. 2011).
