Algae report number 8, 2015
Author: Ann-Turi Skjevik
There were several phytoplankton species with high cell numbers in the samples from the Skagerrak and Kattegat area, above all at the coastal stations Släggö in the Skagerrak and N14 in the Kattegat. The integrated (0-10 m) chlorophyll a concentrations were normal for this month. Chlorophyll a maxima were found at around 15 meters depth in the Skagerrak and at 10 meters in the Kattegat. In the Baltic phytoplankton diversity was very low. Filamentous cyanobacteria were absent and the chlorophyll concentrations were low. The integrated (0-10 m) chlorophyll a concentrations were below normal for this
month at most of the Baltic stations.
