Protist distribution in the Western Fram Strait in summer 2010 based on 454 pyrosequencing of the 18S rDNA
In this study, we present the first comprehensive analyses of the diversity and distribution of marine protist (micro-, nano-, and picoeukaryotes) in the Western Fram Strait, using 454-pyrosequencing and high-pressure liquid chromatography (HPLC) at five stations in summer 2010. Three stations (T1;...

In this study, we present the first comprehensive analyses of the diversity and distribution of marine protist (micro-, nano-, and picoeukaryotes) in the Western Fram Strait, using 454-pyrosequencing and high-pressure liquid chromatography (HPLC) at five stations in summer 2010. Three stations (T1; T5; T7) were influenced by Polar Water, characterized by cold water with lower salinity (<33) and different extents of ice concentrations.
