Gas hydrate recycling: overview and future directions

Natural gas hydrates are an important component of the global and oceanic biogeochemical cycle. However, much remains to be understood about gas hydrate systems, including processes resulting in the accumulation of high-concentration deposits. Gas hydrate recycling is a prominent mechanism in producing elevated hydrate saturations near the base of the gas hydrate stability zone (BGHSZ). During gas hydrate recycling, the BGHSZ moves upward relative to a given interval of hydrate-bearing sediment
