The taste of salt
The Baltic Sea is characterized by its distinct horizontal and vertical pelagic salinity gradient, with the unique feature that 62 % of its surface zone is represented by brackish conditions (5-8 salinity). Observations concerning the diversity of pelagic microorganisms in the Baltic Sea demonstrated the presence of marine as well as freshwater taxa, but no coherent view exists on the area of a shift between marine and freshwater microorganisms, or the composition of potential brackish water microbial assemblages.
Phylogenetic markers are investigated for transects covering the horizontal and vertical salinity gradient of the whole Baltic Sea. The bacterial diversity and abundance will be studied applying 16S rRNA/rRNA gene Tag pyrosequencing analyses, resulting in the first biogeographical as well as microbial richness mapping of the Baltic Sea on a high resolution, three-dimensional basis.
