Abstract
Purpose. Along the Black Sea coast different limans (nearshore lakes) content the valuable recreational resources. And can to use for increasing of valuable of fish species. Correspondingly, salinity changing is significantly fix as a indicator of general environment of the limanic natural system. Among the Black Sea coastal limans, important significant attach for Tiligul liman, that is dippiest (22,2 m). Salinity of Tiligul liman developed different authors, but made earlier studies practically did not concern the seasonal changes in Tiligul estuary in current very specific climate conditions. The aim of the study is to identify salinity Tiligul liman a few years after the last test in dry conditions without significant rainfall and after five consecutive very warm decades of September-October 2015. Data & Methods. In the middle autumn 2015 19 simples were imitated within southern part of the limanic aquatory. They were used as a basis for assessing salinity Tiligul liman and comparative material to the results of other authors and further continuation of long-term series of values of salinity in the liman. Results. According to the research the salinity of liman waters in October 2015 ranged from 18,6 ‰ to 24,9 ‰, with an average of 22,25 ‰, which is 48.3% higher compared to the average liman’s salinity for 150 years. The main factor determining the fluctuations in salinity of Tiligul liman is its water balance. The basic reason of noted salinity in October 2015 were dry weather without considerable rains, strong winds and average daily temperatures more than +15° C, which caused the lack of inflow of fresh water into the liman and intense evaporation from the surface. The obtained datum have great sense for rational usage of basic natural resources of Tiligul liman.
