Estimation of CO2 fluxes in the “atmosphere–water” system in the south Lake Baikal littoral with the floating chamber method

In this work, we discuss the applicability of the chamber method for measurements of carbon dioxide fluxes between the atmosphere and water in the littoral of Lake Baikal. Advantages and disadvantages of the method are considered. Previously submitted data are compared with observations in 2011–2014...

Description
Summary:In this work, we discuss the applicability of the chamber method for measurements of carbon dioxide fluxes between the atmosphere and water in the littoral of Lake Baikal. Advantages and disadvantages of the method are considered. Previously submitted data are compared with observations in 2011–2014, when dramatically different weather situations occurred. It is shown that interannual variations in the total CO 2 fluxes are much weaker than their seasonal variations. The annual flux of carbon dioxide from atmosphere to the water surface in the littoral of Lake Baikal is assessed to be at least 6.5–7 g/m 2 per year in an “open water” period.
