Kai kurių biogeninių elementų koncentracijų variacijų dėsningumai Baltijos jūros Lietuvos ekonominėje zonoje žiemos metu

Abstract

Mineral nitrogen and phosphorus and salinity data collected in Lithuanian coastal zone of the Baltic Sea in winter of 1992-1998 were assessed. Classification of observed situations according to the meterological parameters was performed. Impact of wind direction and velocity was observed to be of high significance to the spreading of coastal water from the Kurshiu Marios Lagoon. When the winds of E, SE, S, SW and W directions or calm enable the fresh water outflow from the Kurshiu Marios Lagoon significant linear dependence between mineral nitrogen and salinity concentrations (r<-0.9) is observed. Futhermore less significant dependence is observed to be under the same meterological conditions between the mineral phosphorus and salinity (r<-0.8).
