Detailed explanation-1: -New research shows reservoirs of ocean methane in mid-latitude regions will not be released to the atmosphere under warming conditions. Deep below the ocean’s surface, the seafloor contains large quantities of naturally occurring, ice-like deposits made up of water and concentrated methane gas.

Detailed explanation-2: -The ocean is one of the natural sources of methane, but previous estimates of methane emissions from the ocean are associated with large uncertainties.

Detailed explanation-3: -There are methane hydrates within the permafrost in Arctic areas, where cold temperatures year round keep them frozen. The sediments of the deeper parts of the continental shelves also contain methane hydrates, where they are stable under the cold, high-pressure conditions found there.
