In September 8-14, 2025, Limnological Institute SB RAS and Molchanov-Sibirsky Irkutsk Regional State Multipurpose Scientific Library will host the Eighth International Vereshchagin Baikal Conference in the memory of the outstanding Russian scientist Gleb Yu. Vereshchagin who headed the comprehensive large-scale studies at Lake Baikal. The Conference has a rich history, being held every five years since 1989 at Limnological Institute SB RAS.

The year 2025 is significant for the beginning of research on Lake Baikal: 100 years ago, in 1925, the Baikal Expedition of the USSR Academy of Sciences began its work, led by G.Yu. Vereshchagin, K.I. Meyer, T.B. Forsh, N.P. Predtechensky, I.P. Sidorychev, E. Perfil'ev, V.N. Sukachev, N.A. Konovalov, V.A. Povarnitsyn, P.V. Tikhomirov, E.V. Ivanov and other researchers took part. These expeditions, carried out in 1925 and in the following years, made it possible to obtain unique data on the flora and fauna of Lake Baikal.

The following scientific problems and research perspectives are planned for discussion at the Conference:

• Biodiversity of large freshwater bodies: sustainability and mechanisms of formation;
• Hydrological and hydrophysical processes and their effect on the state of aquatic environments;
• Atmospheric aerosol, precipitation, and exchange processes in the atmosphere-water surface-biota system;
• Current critical factors of natural and anthropogenic origin affecting the ecological state of aquatic environments;
• Biological water resources and their rational use
• Cycles of organic matter and nutrients;
• Molecular ecology of hydrobionts;
• Silica in nature;
• Scientific background of measures necessary for the preservation of water bodies;
• Gas hydrates and other hydrocarbons in freshwater bodies;
• Toxicology issues of aquatic organisms, persistent organic pollutants in aquatic ecosystems;
• Approaches and methods for direct and remote control monitoring of the aquatic environment;

The official languages of the Conference are English and Russian
