THE INTERACTION OF CO_2 BETWEEN THE ATMOSPHERE AND SURFACE WATERS OF LAKE BAIKAL AND THE INFLUENCE OF WATER COMPOSITION

摘要

Investigations into the inventory of CO_2 in the hydrosphere are primarily aimed gas exchange between the atmosphere and oceans. However, lakes often are not considered as possible sources and sinks, even if they can be locally important for many geographical regions. Lake Baikal covers a tremendous area and has locally high biotic activity, and thus it can be expected to play an essential role in regional CO_2 dynamics. Measurements of atmospheric CO_2, dissolved gases and various aqueous chemical parameters were performed at the Limnological Institute SB RAS site near Bolshie Koty in 2003-2004
