Sentences with phrase «trapped by the permafrost»

• Significantly, the East Siberian Arctic Shelf, ESAS, has up to 1000 Gt of methane reserves, and it is highly believable that 1 % of this (or up to 10 Gt) is in the form of free gas trapped underneath the currently degrading subsea permafrost cap, which could be released within the next few decades by a combination of increasing Arctic Ocean water temperatures, increased storm activity, and possible increases in seismic activity.
