Relevant methane emission to the atmosphere from a geological gas manifestation
Quantifying natural geological sources of methane (CH 4 ) allows to improve the assessment of anthropogenic emissions to the atmosphere from fossil fuel industries. The global CH 4 flux of geological gas is, however, an object of debate. Recent fossil ( 14 C-free) CH 4 measurements in preindustrial-...
