REGISTRATION OF PROFILOGRAMS OF MARINE AND FRESHWATER WATER BODIES USING A SUBMERSIBLE AUTONOMOUS MULTIPARAMETER PROBE

Full-scale tests of a multiparametric autonomous station in the conditions of fresh and marine water bodies have been performed. The results of recording profilograms of changes in hydrophysical (temperature, electrical conductivity, turbidity, dissolved oxygen, alkalinity, redox potential) and biological (chlorophyll content, quantum yield and fluorescence intensity of phytoplankton cells) parameters of the Pavlopolskoe and Starokrymskoe reservoirs, as well as the coastal zone of the Sea of Azov in the vicinity of Yuryevka village are presented. The change in the distribution and photosynthetic activity of natural phytoplankton in the horizons of seawater is shown. Hydrophysical profiles of the studied water bodies have been obtained. The effectiveness of using a multiparametric measurement station for environmental monitoring of surface natural waters with the ability to register profilograms of the main indicators of the aquatic environment has been proven.
