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 Kattegat stations. Relatively high abundance of small flagellates above all cryptomonads were found in at all stations along the west coast. Only few cells were also recorded at all stations in the Baltic Sea. Small flagellates mainly belonging to the cryptomonads were also recorded. Several individuals of the genus Chrysochromulina (prymnesiophyceae) were observed at the Western Gotland Basin (BY38) and at the Bornholm deep (BY5).
