Abstract

The analysis of variability of water temperature ac- cording to the termokosa set on the D6 platform in 2015 in a southeast part of the Baltic Sea is provided in article. In total 10 temperature sensors on the different horizons, discretization on time of 1 min., depth in an installation site of 29 m were set. For the researched period water temperature changed within 2.4—21 °C. 5 upwellings on the horizons of 24 and 28 m are re- corded. In the fall and in the spring the daily course with an amplitude about 1 °C is well selected. During the period from 22.10.2015 till 15.03.2016 stratification was absent that is caused by the strong autumn and winter convective agitation. Semidiurnal oscillations of water temperature, and also from 4 to 15 minutes, high-frequency with the periods, are recorded.

Keywords

the Baltic Sea, variability of temperature, termokosa.
