In the Skagerrak and Kattegat the plankton flora is rich and dominated of "early summer diatoms". Ceratians are common in the Skagerrak and in the Kattegat there is a bloom of cf. Heterosigma sp. In the southeast part of the Baltic there are still remains of the spring bloom. In the other areas it …

In the Skagerrak the spring bloom has passed, but the plankton flora is still relatively rich. Near the coast Dinophysis norvegica is very common. In the Kattegat it is a post spring bloom situation with low abundance of most species. In the Baltic Sea the spring bloom has terminated in the …

In the Kattegat the spring bloom is in a late stage. In the coastal Skagerrak the bloom is still developing and in the open Skagerrak it is just beginning. The bloom of the potentially toxic Chattonella sp. is no longer present. In the Baltic Sea the winter situation is slowly ending and the first …

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 …
