Abstract

Measured СО₂ flux between the atmosphere and water and the dynamics of biogenic elements in cardinally different water basins: Lake Baikal and coastal maritime conditions, are compared. We conduct regular cycles of combined observations at the Southern Baikal shore for different seasons at the Baikal Atmospheric-Limnological Observatory (BALO). The measurements under maritime conditions were conducted at the stationary station of the Far East Branch of the Russian Academy of Sciences at Schultz Cape in the period of October 6-10 of 2012 and October 7-13 of 2013, as well as in 2014 a cycle of investigations on the assessment of spatial variability was carried out. The most remarkable distinctive feature of the content of dissolved gases and their flux under maritime conditions (Far East) is the permanent sink of carbon dioxide from the atmosphere onto the water surface. At Lake Baikal in this period, we observed the pronounced diurnal dynamics characterized by the daytime sink and nighttime emission of СО₂ into the atmosphere.
