摘要: Abstract We report long-term comprehensive measurements of CO2 in the atmosphere, surface water and major nutrients obtained for period 2004–2018. The research was conducted at Baikal Atmospheric Limnological Observatory (BALO), which is located coastal zone South (coordinates 51° 54′ N, 105° 05′ E). seasonal variation these characteristics analyzed. For our site, during open (May-December) we assessed average flux CO2, amounted to −155 mmol m−2 y−1 (sink from atmosphere surface). Carbon dioxide content near-water air Lake rises with a rate 2.46 ppm per year, good agreement global trend. common effect many factors (often multi-directional), such as variability weather conditions, hydrological processes productivity cycles aquatic plankton waters, cause strong variations characteristics, observed different seasons years. Under conditions inter-annual all trend calculations using observations did not allow us reveal reliable tendencies changes concentrations.
