Summary of the locations where gas hydrate occurs beneath the seafloor, in permafrost areas, and beneath some ice sheets, along with the processes (shown in red) that destroy methane (sinks ...

5. Seafloor gas hydrate mounds (trace). Dissociation: The breakdown of gas hydrate occurs by dissociation to its constituent water and gas. Hyperthermals: Periods characterized by extremely warm ...

the two envisioned what would happen when gigantic methane bubbles explode from natural fissures on the seafloor. The methane—normally frozen at great pressure as gas hydrates embedded within ...

Part of this problem lies in the limited number of available library spectra, especially for salt hydrates that are formed at high pressure and low temperature, conditions found under the icy crust.
