Primary Productivity Estimates Based On The Remote Sea Surface Temperature Data In The Baltic Sea

The satellite-derived information has been widely used to observe the large-scale dynamics of marine ecosystems and to estimate primary productivity in the world ocean. This study is devoted to the assessment of opportunities for modelling of primary production through the satellite data (MODIS-Aqua and -Terra) on the sea surface temperature. The analysis of the South-eastern Baltic Sea in situ datasets of ecosystem parameters, obtained for 2003-2015, shows that the temperature of the upper 5-m layer is an efficient indicator of primary production horizontal distribution. A simple regional empirical model has been developed. It demonstrates the connection between primary production and remote sea surface temperature, and the variability of primary production values. The model performs a strong statistical significance and sufficient accuracy for practical use. The relationships between the measured and modelled estimates of primary production are tested by using linear regression.
