Abstract
Estimates of specific fluxes of methane and carbon dioxide into the atmosphere, associated with groundwater sources of continuous permafrost in central Yakutia were obtained for the first time. Average specific flux of methane from intensively emitting groundwater sources is 211±85 mgC·m-2·h-1, and carbon dioxide is 93±67 mgC·m-2·h-1, which significantly exceeds specific fluxes of these gases from many subaerial ecosystems. Dissolved methane concentration is also high and varies from 1.6 to 4.8 mg·L-1. Research results emphasize the importance of groundwater discharge areas as methane sources in continuous permafrost and indicate the need for their further study in order to more accurately account for its contribution to the overall greenhouse gas balance and establish the origin of greenhouse gases.
