Abstract
The investigation of the qualitative and quantitative composition of the phytoplankton in Tvaeren (Locality 7), a bay of the Baltic, was carried out during the period April 1961 to October 1963. Comprehensive data exist concerning physical and chemical conditions; some of them are included in this paper. A low number of species occur in brackish water; most of them belong to the groups Diatomeae and Peridineae. The total volumes of phytoplankton are low and show peaks only in spring, with some genera, Sceletonema, Thalassiosira and Gonyaulax, predominating. The vertical and seasonal distribution of different groups is discussed. With the exception of the periods of circulation the total volumes showed a marked decrease from c. 25 m and deeper. At 50-70 m the occurrence of some Peridineae often caused a marked increase in total volumes. A comparison with corresponding values from another locality, situated at Bergoe south of Locality 7 in Tvaeren, did not show any great difference.
