Experimental Assessment of the Carbon Dioxide Flow in the Atmosphere-Water System of the Littoral and Pelagic Zones of Lake Baikal during Hydrological Summer

摘要

Long-term hydrochemical studies carried out in Lake Baikal from the 1950s through the 1990s revealed spatial patterns of variations in basic chemical components and concentrations of dissolved gases in its waters [1, 2]. At the same time, no immediate measurements of carbon dioxide flows, which represents one of the most important gases in the context of the recent problems concerning gas exchange in the water-atmosphere system, were conducted by previous researchers [3-7]. Moreover, information on the concentrations of CO_2 in the atmosphere was also unavailable and all the assessments of its flow are based on average global values.
