Abstract
The paper is dedicated to studies of hydrological & hydrochemical parameters’ vertical distribution in the area where water masses of different origin mix. The studies have been based on the collected massif of hydrometeorological information on the Zmiinyi Island shelf area accumulated in National Mechnikovs University of Odessa. The objective of the work has been studies of physicochemical parameters vertical distribution forming peculiarities in water column and the level of different factors’ influence on this distribution.To perform the studies the data about wind and currents speed and direction, conductivity, temperature, oxygen content and pH in the Zmiinyi Island coastal waters in 2003-2013 have been used. Measurements and modelling results have been processed using statistics and comparative analysis methods with the application of ARCGIS and Excel software. Seasonal regularities in hydrological and hydrochemical parameters’ vertical distribution of in the Zmiinyi Island coastal waters have been confirmed. Deviations from the characteristic seasonal variation of hydrological and hydrochemical parameters’ vertical distribution have been revealed and assumptions about their reasons made.For the years 2008-2013 the tendency towards frequency increase of eastern, southern and western winds has been pointed out, which intensify inflow of the Danubian waters and the deep waters of high salinity into the island aquatorium. The influence of the island shelf relief has been shown, which is making itself evident in episodic upwelling, «shadowing» effects of the island and local disturbances in the above mentioned parameters’ distribution with depth.It has been confirmed that peculiarities of vertical distribution of hydrological and hydrochemical parameters in water column could be explained by proximity of the island to the Danube mouth, to northern branch of the general Black Sea current and to the deeper parts of the sea. Non-periodical deviations from seasonal vertical distribution of the above mentioned parameters are connected with concrete meteorological situations are of synoptic scale. Influence of morphological peculiarities of the shelf on currents structure and upwelling forming in the immediate proximity (up to 500 m) to the island has been established. No unambiguous connection between oxygen content in bottom layers and upwelling has been found.
