SEASONAL CHANGES OF NUTRIENTS CONCENTRATION IN TWO SHALLOW ESTUARINE LAKES GARDNO AND ŁEBSKO; COMPARISON
Journal Title: Baltic Coastal Zone - Year 2009, Vol 13, Issue 1
Abstract
The aim of this paper was the presentation and comparison of seasonal biogens changes and trophy state classification of two biggest shallow coastal lakes Gardno and Łebsko, located in the northern part of Poland, along the southern coast of the Baltic Sea. Measurements were conducted once a month from April to December 2007. For the purpose of this article at each lake one measurement station was selected, to represent well mixed area of the lakes, far from outlet to the sea and rivers. Performed measurements showed that the lakes are similar. The differences, observed between biogens concentration in lakes were statistically insignificant. Seasonal dynamics of nutrients concentration in lakes indicated that the lakes are typical shallow lakes. Moreover, the summer concentration of total nitrogen and phosphorus qualify these lakes as eutrophic.
