Abstract

Results of data analysis, based on measurement of atmospheric concentrations of methane in the shallow part of the East Siberian shelf (ESS) are presented in this work. It was shown that methane emission in the atmosphere is determined not only by natural factors, but is also sensitive to anthropogenic influences, like the engine mode of a ship. It was determined that the hydraulic impact, which occurs when starting a ship’s engine after drifting through a shallow, can induce a great methane outbreak in the atmosphere. The power of these “short-lived” sources can exceed the power of any one deep-water mud volcano. In the shallow parts of the ESS, the anthropogenic factor can be one of the important factors effecting methane outbreaks in the atmosphere.
