Algae report number 1, 2011

Summary

The plankton community was dominated by diatoms in both Skagerrak and Kattegat and Skeletonema marinoi dominated at all stations. Different cryptomonads such as Teleaulax were also common. The chl a measurements were overall low and no tendency of a forthcoming spring bloom could be seen. A bit higher chl a content was however recorded at Släggö and Anholt E but still within normally low for the season. All stations in the Baltic Sea contained few species with only few cells of each species recorded. The chl a levels were mostly below 1 μg/l which is within normal for the season. Small flagellates and mostly cryptomonads dominated the scarce samples.
