In the Kattegat and coastal Skagerrak the spring bloom has developed. At the same time a bloom of the potentially toxic Chattonella sp. is developing in the whole area. In the Baltic Sea the winter situation still prevails and only small amounts of phytoplankton are present.

In the Skagerrak and the Kattegat the plankton composition and abundance has reached a winter situation with small amounts of phytoplankton. In the Baltic Sea the winter situation is obvious by the small amounts of phytoplankton.

In the Skagerrak and the Kattegat the autumn bloom was passed and the succession went towards a winter situation with small amounts of phytoplankton. In the Baltic cyanobacteria had almost disappeared and large diatoms, a few dinoflagellates and small flagellates dominated. West of Gotland there …

In the Skagerrak and the Kattegat the autumn bloom, dominated by diatoms, was developing. Large amounts of Chaetoceros and Pseudo-nitzschia species were present. Dinoflagellates were also common. In the Baltic cyanobacteria had almost disappeared and large diatoms, some dinoflagellates and small …

In the open Skagerrak the plankton flora was poor with few diatoms and dinoflagellates. Close to the coast the abundance was higher with more diatoms and a small bloom of Skeletonema costatum. In the Kattegat diatoms were absent and dinoflagellates were few. Chrysochromulina spp. were the most …

In the Skagerrak the plankton flora was poor with few diatoms and dinoflagellates. Toxic species as Dinophysis acuminata, Dinophysis rotundata, cf. Alexandrium pseudogonyaulax and Chrysochromulina spp. were present in low concentrations. In the Kattegat a diatom bloom of Guinardia flaccida, …

In the Skagerrak diatoms and dinoflagellates were scarce, except for Heterocapsa rotundata. In the Kattegat a diatom bloom of Guinardia flaccida and Proboscia alata decreased between the two samplings. Small amounts of Baltic species indicated outflow of low saline water. Toxic species were not …

In the Skagerrak there was a diatom bloom. Dinoflagellates were not very abundant. In the Kattegat the diatom bloom developed and the potentially toxic Dinophysis acuminata decreased from very high numbers. Chrysochromulina spp. was present but not in high numbers. In the Baltic the plankton flora …

In the open Skagerrak and Kattegat the plankton flora is rather poor and dominated by flagellates. In the coastal area of the Skagerrak there is a more divers phytoplankton community with some diatoms of importance. In the Baltic the plankton flora is poor, dominated by dinoflagellates. Small …

In the Skagerrak and the Kattegat the spring bloom has terminated and the plankton flora is poor, although in a late state of the bloom near the coast. In the southwest part of the Baltic the spring bloom has terminated. Further east and north the spring bloom is going on.
