Certain gases can combine with water to form solids—gas hydrates—that are stable at high pressures and low temperatures1,2. Conditions appropriate for gas-hydrate formation exist in many marine sediments where there is a supply of methane. Seismic reflection profiles across continental margins indicate the frequent occurrence of gas hydrate within the upper few hundred metres of sea-floor sediments, overlying deeper zones containing bubbles of free gas3–9. If large volumes of methane are stored… 
Escape of methane gas through sediment waves in a large methane hydrate province
Despite paleoceanographic evidence that large quantities of methane have escaped from marine gas hydrates into the oceans, the sites and mechanisms of methane release remain largely speculative. New
Gas hydrates: past and future geohazard?
TLDR
The destabilization of gas hydrate reserves in permafrost areas is more certain as climate models predict that high-latitude regions will be disproportionately affected by global warming with temperature increases of over 12°C predicted for much of North America and Northern Asia.
The Global Occurrence of Natural Gas Hydrate
Natural gas hydrate occurs worldwide in oceanic sediment of continental and insular slopes and rises of active and passive margins, in deep-water sediment of inland lakes and seas, and in polar
Energy resource potential of natural gas hydrates
The discovery of large gas hydrate accumulations in terrestrial per mafrost regions of the Arctic and beneath the sea along the outer continental margins of the world's oceans has heightened interest
In situ methane concentrations at Hydrate Ridge, offshore Oregon: New constraints on the global gas hydrate inventory from an active margin
The widespread presence of bottom-simulating reflectors (BSRs) on continental margins has bolstered suggestions that gas hydrates and free gas constitute a large dynamic reservoir of CH4 carbon and a

TLDR
Waveform inversion of seismic reflection data can be used to estimate from seismic data worldwide the velocity structure of a BSR and its thickness, and predicts that sediment pores beneath the BSR contain free methane for approximately 30 meters.
