During this season, due to natural factors (low water temperature and biota activity, cessation of external gas exchange, etc.), internal processes within the reservoir slow down, creating a unique hydrochemical regime. The currently observed climate warming, which occurs predominantly in winter and leads to an annual redistribution of water flow in the artificial reservoir, makes it increasingly important to study the dynamics of key hydrochemical components under the ice and the role of this period in ecosystem processes.
On February 19-20, specialists from the Fisheries Ecology Laboratory of the Saratov Branch of the All-Russian Research Institute of Fisheries and Oceanography (VNIRO) collected monitoring water samples in the upper zone of the Volgograd Reservoir.
The results indicate a favorable oxygen regime in the study area. The content of organic matter and nutrients is within the long-term average. The results obtained will be used to assess long-term variations in the main hydrochemical components of the Volgograd Reservoir under changing environmental conditions.
