Environmental monitoring of Lake Baikal
Hydro-chemical characteristic of Lake Baikal water
The annual data of hydrochemical observations in the 200-metre layer of Lake Baikal in 2013
The page shows the map of the BNT with the display of water observation areas of Lake Baikal according to the hydrochemical indicators. If you hover over the observation area, the annual data of hydrochemical observations in the 200-metre layer of Lake Baikal in 2013 will appear in the pop-up window.
