The employees of Marine Hydrophysical Institute of RAS have returned from a scientific expedition to Lake Teletskoye, which took place from August 1 to August 10, 2024. The research was carried out within the scope of the state assignment FNNN-2024-0012 “Operational Oceanology” and was aimed at studying the spatial and temporal dynamics of the hydrophysical and hydrobiological characteristics of the lake water during the period of stable temperature stratification.

The expedition consisted of young specialists of the Institute:

• Elena Nikolaevna Korchemkina, PhD (Phys.–Math.), Senior Research Associate of the Marine Optics and Biophysics Department of the Federal State Budgetary Scientific Institution Federal Research Center “Marine Hydrophysical Institute”;
• Aleksandr Aleksandrovich Latushkin, PhD (Geogr.), Research Associate of the Marine Optics and Biophysics Department of the Federal State Budgetary Scientific Institution Federal Research Center “Marine Hydrophysical Institute”;
• Oleg Borisovich Kudinov, PhD (Tech.), Research Associate of the Marine Optics and Biophysics Department of the Federal State Budgetary Scientific Institution Federal Research Center “Marine Hydrophysical Institute”;
• Pavel Nikolaevich Lishaev, Junior Research Associate of the Department of Dynamics of the Oceanic Processes.

Despite unfavorable weather conditions, the scientific team successfully completed the stated work program. During the expedition, more than 120 vertical soundings were carried out using a multiparametric hydrological-hydrooptical measuring complex. In addition, over 10 tacks were made with the spectral luminance meter.

The expedition participants have noted that the data obtained will allow them to better understand the dynamics of the processes occurring in Lake Teletskoye during summer. The findings of the expedition will be used for further scientific research and the development of models describing hydrophysical processes in large freshwater bodies.
