… methane hydrate deposits are believed to be a larger hydrocarbon resource than all of the world’s oil, natural gas and coal resources combined.  If these deposits can be efficiently and economically developed, methane hydrate could become the next energy game changer. __Geology.com
Japanese researchers at Okayama University have unlocked some the mysteries of how methane is stored and released from methane hydrates. Methane hydrates are formed in sediments around the world, and have been most frequently found in sedimentary deposits along continental margins.
World reserves of the frozen gas are enormous. Geologists estimate that significantly more hydrocarbons are bound in the form of methane hydrate than in all known reserves of coal, natural gas and oil combined. “There is simply so much of it that it cannot be ignored,” says leading expert Gerhard Bohrman of the Research Center for Ocean Margins (RCOM) in the northern German city of Bremen. __ Gerald Traufetter in Der Spiegel

Some recent estimates of the size of the global methane hydrate reservoir have been scaled down from earlier estimates. But such “minimalist” estimates fail to take into account the regenerative nature of underlying natural gas which eventually becomes methane hydrate (or clathrate).
There are at least two ways in which methane hydrates and continental shelf methane can be seen as renewable. First, abiogenic methane is constantly being generated in the mantle, much of which moves upward into crustal layers and sediments. Second, biogenic methane is constantly generated by methanogenic microbes in seafloor sediments, from organic matter always forms a part of ocean sedimentary layers.
Some information on biotic vs abiotic methane. Methane “reservoir levels” are a moving target. Just when you think you have it figured out, you get hit in the head by something you didn’t know was there. The same is true for oil & coal resources.
A study on seafloor methane seeps and their effect on oxygen consumption. We should keep in mind that undersea oil & gas seeps are a natural part of the undersea ecosystem worldwide. Entire biomass ecosystems have evolved to deal with this ever present phenomenon.
Meanwhile, here is what Obama is doing about US oil & gas production, while he is claiming to be doing something entirely different. How you know a politician is lying, is when you see his mouth moving and hear sounds coming out of it. He has other ways of lying, of course, but that is one good way to know.
