Abstract
Based on the regional ocean-ice model SibCIOM, calculations have been made for modeling the Arctic Ocean water masses conditions and dissolved methane transfer for the period from 1970 to 2019. We have performed the model analysis of methane emissions from the Arctic seas caused by gas release at the "ocean-bottom" interface. It is shown that the East Siberian shelf seas provide significant contributions to the total methane emission in the region. The spatial variability of the methane emissions into the atmosphere is primarily due to the region's peculiarities and ice conditions circulation. The estimated methane flux from the Arctic shelf seas has amounted to 2 Tg per year.
