The Sea of Azov subarea of the Black Sea LME - oceanographic database
- Maps of the vertical distribution of climatic standards of water temperature and salinity
- Maps of the vertical distribution of climatic anomalies of water temperature and salinity
The oceanographic database of the Sea of Azov subarea of the Black Sea LME contains 66 609 stations for the period of 1891 to 2012 (Figure 1).
The distribution of stations by years and months is presented in Figure 2.
Tables and charts of station distribution for every month of each year for the considered period are in Inventory and archive data section.
Compared to the Climatic Atlas of the Sea of Azov 2008 (Matishov et al., 2008) ), the database covers an additional 31 192 stations(Figure 3), which fills in the existing data gaps for the periods of 1960-1970, and 1980-1990.
To analyze the long-term variability of hydrological characteristics of the Sea of Azov, two sections are considered:
- «Kerch Strait – Don Delta» (Figure 4)), which is a continuation of Samsun – the Kerch Strait section;
- «Igorevka – Kuban Delta» (Figure 5).
A number of stations located in the belt of 20 km on both sides and used for the construction of climatic standards and anomalies is correlated with every section. The total number of stations for the Kerch Strait–Don Delta is 27 615, and the Igorevka – Kuban Delta covers 5 619 stations.
Maps of the vertical distributions of the climatic standarts and anomalies of temperature and salinity are given in section Time series of water temperature and salinity
