This dataset shows model results for the average bottom temperature in the Baltic region in the plant growth season from April to September. The map was developed by NERI/Denmark for the BSR INTERREG IIIB project BALANCE.

The salinity and temperature data cover stations from the Bothnian Bay to the Baltic Proper, including the Gulf of Finland and the Gulf of Riga. Also stations in the Danish straits, the Kattegat, the Skagerrak and the German Bight were included in the analysis. Throughout the calculations the modelled temperature was adjusted towards observed average temperature (April-August) and salinity (January-December) values from 1999-2004.

In order to be displayed in the HELCOM Map Service, the map coordinate system and projection was changed from original WGS1984_UTM34N to ETRS_1989_LAEA.
