The approach, called tunable infrared laser direct absorption spectroscopy, detects the ratio of methane isotopes, which can provide a «fingerprint» to differentiate between two common origins: microbial, in which microorganisms, typically living in wetlands or the guts of animals, produce methane as a metabolic byproduct; or thermogenic, in which organic matter, buried deep within the Earth, decays to methane at high temperatures.

For example, some suggest that melting arctic permafrost could result in the decay of huge amounts of organic matter, releasing more CO2 and methane.

Much of the organic matter associated with this high productivity sinks onto the relatively wide continental shelf, where decay results in the reduction of dissolved oxygen in bottom waters [5].
