Abstract:

This paper is aimed at analyzing the spatial distribution of carbon dioxide and methane concentrations in the atmosphere and in the surface water of Lake Baikal. Investigation of interaction processes between air and fresh water is of special importance for the unique lake ecosystem since the gas exchange is governed predominantly by aquatic biota on the one hand, and it has a significant impact on biota activity on the other hand.
In recent years we have significantly improved our capabilities when measuring CO₂ and CH₄ partial pressures in the surface water along the research vessel route by means of designing a unique mobile station. This made it possible to extend significantly our scope of research and to pioneer carrying out simultaneous measurements of the flux direction of carbon dioxide and methane in the waters of Lake Baikal.
Analysis of the flux distribution data showed that during spring campaign 2013 fluxes were characterized by the predominant sink of carbon dioxide into the lake surface, and vice versa, we observed a release of methane into the atmosphere during the whole route of research vessel.
