Estimation of the global inventory of methane hydrates in marine sediments using transfer functions [PDF]
, 2013 The accumulation of gas hydrates in marine sediments is essentially controlled by the accumulation of particulate organic carbon (POC) which is microbially converted into methane, the thickness of the gas hydrate stability zone (GHSZ) where methane can ...

Methane Hydration‐Shell Structure and Fragility
Angewandte Chemie, 2018 AbstractThe influence of oily molecules on the structure of liquid water is a question of importance to biology and geology and many other fields. Previous experimental, theoretical, and simulation studies of methane in liquid water have reached widely conflicting conclusions regarding the structure of hydrophobic hydration‐shells.
