-20 meters) chlorophyll a concentrations from the Baltic Sea were within normal for the season at all stations. Cryptomonads together with the genus Pyramimonas were dominating the samples at all stations. Both colony forming and filamentous cyanobacteria had diminished since the last expedition, but the Last updated: Apr 23, 2014

and especially the heterotrophic dinoflagellate Peridiniella danica was common. Only a few cells of the ichtyotoxic (ichtyo = fish) genus Pseudochattonella were recorded on this cruise. A spring bloom situation was evident in the southern and western part of the Baltic Sea. A dominance of spring bloom Last updated: Apr 23, 2014

below normal for this month at N14, and normal in the rest of the Kattegat and Skagerrak area. Low cell numbers and few species were present in the Baltic Sea phytoplankton samples. Quite high cell numbers of the filamentous cyanobacterium Aphanizomenon flos-aquae was found at BY38. The integrated Last updated: Mar 02, 2017

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.

North Sea, visible in satellite images https //lance.modaps.eosdis.nasa.gov/imagery/subsets/?subset=Southern_Norway_and_Sweden.2016151.aqua.250m. The cell surface of E. huxleyi causes a bright turquoise coloring of the water when blooming. The species has reached Skagerrak and Kattegat with the currents Last updated: Jun 01, 2016

Relatively few cells were found at all stations which is normal for the season. A quite diverse community but with few cells of each species was however found in the Skagerrak area. The diatom genus Pseudo-nitzschia was found in high abundance at the outer station in Skagerrak (Å17) and at both Last updated: Apr 23, 2014

integrated (0-10 m) chlorophyll a concentrations were normal for this month. The Baltic Sea was mainly dominated by colonies of small cyanobacteria and other small unicells. Large diatoms were common in the Eastern and Southern part of the Baltic Sea. The integrated (0-10 m) chlorophyll a concentrations were Last updated: Nov 02, 2015

coccolithophorids, the most abundant in the Kattegat area. The phytoplankton diversity was low in the Baltic Sea and consequently the chlorophyll concentrations were low. The concentrations were however below what is normal for this month at many stations. Last updated: Dec 05, 2016

All phytoplankton samples from the Skagerrak, the Kattegat and the Baltic Sea had low species diversities. All of the cell counts were very low. All of the Skagerrak stations except Släggö were not visited during the cruise due to bad weather conditions. No further detailed phytoplankton Last updated: Jan 26, 2017
