Ecological Systems and Devices Annotation << Back STUDY OF THE DISTRIBUTION OF SALINITY OVER THE WATER AREA OF THE RESERVOIR A.I. Kim, A.A. Moskvitin, T.E. Kim, M.Yu. Zaytseva This paper presents the results of field measurements of salinity profi les in the waters of the Tunaycha lagoon-type lake (Korsakov District, Sakhalin Oblast). The work was carried out in the spring and autumn periods of 2022 at different points of the reservoir. A submersible probe based on the Aanderaa 4319 conductivity sensor was designed and metrologically tested for research. Based on the results of measurements of the salinity distribution in Lake Tunaycha, an analysis was performed that showed that salinity in the upper layers to a depth of approximately 15 m was observed within 6 ‰. throughout the lake. Keywords: lagoon lake, salinity, conductomer, environmental monitoring, field measurements. DOI: 10.25791/esip.6.2023.1380 Pp. 67-73.
