Time series of water temperature and salinity


1. Maps of the vertical distribution of climatic standards of water temperature and salinity


Vertical distributions of temperature and salinity are averaged for the period of 1884-2012 (climatic standards) for the sections of the Eastern Black Sea. Their location by the vertical corresponds to standard horizons of 0, 5, 10, 15, 20, 25, 30, 50, 75, 100, 150, 200, 250, 300, 350, 400, 450, 500, and further in (every) 100 m to 2500 m. Along the section they are located 40 km of each other.

2. Maps of the vertical distribution of climatic anomalies of water temperature and salinity


To construct time series of water temperature and salinity anomalies, (root-) mean square deviations (σ) of mean values were calculated and set in ratio of σ.


To calculate the anomalies, data from the period of 1891 to 2008 was considered. Based on the data of inter-annual variability of temperature and salinity of sea water, number of cases with «whirling» negative anomalies of water salinity per year, air temperature, sediments, and river runoff (Tuzhilkin, 2008), three time periods were distinguished: 1891-1959, 1960-1979, and 1980-2008. Thus, anomalies of temperature and salinity for the Black Sea were calculated for these time intervals.
