Abstract
All our many-year studies of the gas-exchange processes were carried out at one observation site (BALO) in the littoral of Southern Baikal. Thus, the question about applicability of conclusions and estimates based on these data to the entire littoral zone inevitably arises. In 2014, we succeeded for the first time in organizing the combined research campaign for detailed mapping of the spatial variability of water characteristics in general for the littoral of southern Baikal. The spatial partial distribution of biogenic elements and the pressure of carbon dioxide and methane in the atmospheric surface layer and the surface water layer were studied in August 5-11 of 2014 from onboard of I.D. Papanin Research Vessel (RV). These studies covered, in section, the entire water area of the southern Baikal. The fluorescent characteristics, concentration of biogenic elements, partial pressure of carbon dioxide and methane in the surface water layer and the atmospheric surface layer were determined there. The continuous measurements of carbon dioxide and methane in the surface water and in the atmosphere in the course of the vessel were conducted by a mobile shipborne system, which was complemented with the flow-through fluorimeter. It has been found that the main features of fluxes and the value of dРg, as well as fluorescent characteristics are in a good agreement with the results of many-year measurements obtained in the BALO Observatory for the summer period.
