HYDROPHYSICAL MEASUREMENTS METHODS APPLICATIONS IN NATURAL AND EXPERIMENTAL STUDIES OF PROCESSES IN WATER SYSTEMS
The paper presents methods of complex hydrophysical studies aboard research ship, as well as the description and principle of operation of the hydro-physical instruments (multiparameter flow meter RCM 9 LW, the probe of the 6th generation YSI 600 OMS), which are widely used for measuring various hydrophysical characteristics such as the concentration of dissolved oxygen, conductivity, salinity, total mass of solute, resistivity, temperature, pH, depth,turbidity, etc. The results of hydrophysical structure study of Lake Pleshcheyevo, which have helped to clarify the structure of fields of hydrophysical parameters, are also presented. The obtained data on the distribution of dissolved oxygen is consistent with the data on the structure of currents in the water depth and near the surface.
