Abstract:

The three-dimensional mathematical model of global ocean climate with a spatial resolution of five degrees together with model of the dissolved gas transport by ocean currents is used for a quantitative estimation of scale of a possible methane flux in atmosphere from melting subbottom methane hydrates. Results of experiments give reasonable values of the methane flux to the atmosphere comparable to available estimations. The maximum calculated methane flux to the atmosphere of an order of 8-13 Tg per a year is received.
