Mass fractionation of noble gases in synthetic methane hydrate: Implications for naturally occurring gas hydrate dissociation

<<Carbon and deuterium stable isotopic fractionation during methane formation provides a first-order constraint on the processes (microbial or thermogenic) of methane generation.>> #Environment #Earth https://t.co/1pigKG8wZF

A key challenge in assessing the impact of dissociating gas hydrates on global atmospheric methane is the lack of a technique able to distinguish between methane recently released from gas hydrates & methane emitted from leaky thermogenic reservoirs, [

<<As a consequence of contemporary or longer term (since 15 ka) #climate #warming, gas hydrates in some settings may presently be dissociating and releasing methane and other #gases to the #ocean–#atmosphere #system.>> https://t.co/1pigKG8wZF
