Concentration of nutrients in the water of Southern Baikal in summer

Optical characteristics of Baikal water and their inter-annual, seasonal and diurnal variability depend on plankton composition, suspended particles of organic and inorganic substances, and dissolved chemical compounds. This work analyses the results of comprehensive studies on spatial distribution of nutrients (nitrogen, phosphorus, carbon, and silicon) in the water area of Southern Baikal performed in August 2014. The authors also compare the results of spatial measurements with the data of long-term observations in the littoral zone for summer conditions carried out at the Scientific Research Station of Limnological Institute of the Siberian Branch of the Russian Academy of Sciences.
