Abstract: Due to various Physic and Chemical factors of rivers leading to the sea, the situation seems different topography Throughput rate initial production in the different seasons are different. During 2012 in spring, summer, autumn and winter, in a study of 8 transects of 40 stations. In each transect from Astara to the Turkmen. 5 stations at depths of 5.10.20.50.100m were selected for sampling. The total number of 182 species from seven branches Bacillariophyta, Pyrrophyta, Cyanophyta, Chlorophyta, Euglenophyta, Xantophyta and Chrysophyta phytoplankton were identified. Including 81 species of Bacillariophyta, 33 Cyanophyta, 25 Pyrrophyta, 31 Chlorophyta, 9 Euglenophyta, 1 Xantophyta and Chrysophyta had 1 specie. Our study demonstrates that across Southern Caspian Sea, varying in environmental conditions and morphology, pronounced season and temperature gradients favor the distribution of bulk phytoplankton into more defined layers and seasons, while the depth of the peak and the heterogeneity of individual phytoplankton groups were differentially affected by habitat structure.
