Sažetak
The marine Lake Vlaška (0.5 km2, max. depth 11 m) is part of the Neretva River estuary. In order to analyze hydrographic, chemical and biological parameters, monthly samplings were taken at the « Rogotin» station in the period from April 1999 to April 2000. Samplings were taken from the surface to the bottom at each meter depths. According to hydrodynamic conditions, the water column stratification was persisted throughout the year. A sharp halocline separated the water column into a brackish layer above the halocline, and a marine layer beneath it. The thermocline corresponded to the halocline due to the inflow of colder river water. The water column was well aerated up to depths of three meters throughout the year, while there was hypoxia or anoxia below eight meter depths. This paper compares the molar ratios of nutrients /Si:P, TIN:P, Si:TIN, NO3:NH4, Si:IL (index of light), TIN:IL/ to phytoplankton abundance, both above and below the pycnocline.
