2 Ιουν 2017 · Andreassen et al. found evidence of large craters embedded within methane-leaking subglacial sediments in the Barents Sea, Norway. They propose that the thinning of the ice sheet at the end of recent glacial cycles decreased the pressure on pockets of hydrates buried in the seafloor, resulting in explosive blow-outs.
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.
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.
5 Ιουν 2017 · Ancient Methane Explosions Rocked the Arctic Ocean at the End of the Last Ice Age. As retreating ice relieved seafloor pressures, trapped methane burst through to the water column, study says
7 Φεβ 2019 · In this video, Ruppel explains the fundamentals of methane hydrates, where they are concentrated, and why. The areas of greatest concern are in the Arctic continental shelf, which during the last glaciation, when sea level was lower, were vast northern permafrost grasslands.
1 Οκτ 2014 · Methane hydrate turns out to defy simple questions about whether it is an energy blessing or a climate curse, posing much larger puzzles about how global systems work and what their time frames...
