ConclusionConclusion1. The environmental conditions allow to divide the Bays on three groups. The
Lunskiy affected on the biggest influence of marine water, the Piltun and Nabil – the lowest. Chayvo and Nyyskiy have intermediate position.
2. Three types of water were detected in the bays.3. The bays are geochemical barrier for suspend solids and metals. 4. The hydrodynamic conditions are more important factor, which forms different
types of pelagic and benthic communities. Peculiar phytoplankton communities are formed near the river mouths under an influence of river run-off.
5. Benthic communities in brackish water have higher biomass and species diversity than both fresh and marine communities.
6. Fresh water benthic communities have the widest spreading in Piltun. The brackish water benthic communities covered the most area of Nyyskiy, Chayvo andLunskiy bays.
7. Relatively high content of some trace metals in lagoons are the result of naturalgeochemical conditions with terrestial concentrations of metals.
