Methane hydrate-bearing sediments: Pore habit and implications
Hydrate-bearing sediments are relevant to the organic carbon cycle, seafloor instability, and as a potential energy resource. Sediment characteristics affect hydrate formation, gas migration and recovery strategies. We combine the physics of granular materials with robust compaction models to estima...

Then, we compare these results to an extensive database of worldwide hydrate accumulations compiled from published studies.
