Algal situation reports

Reports from SMHIs offshore sampling programme, which describe the algal situation in marine waters surrounding Sweden.

Algae report number 7, 2016

The diatom Proboscia alata was found in relatively high concentrations at all stations in the Skagerrak. One or two chlorophyll maxima were found at all stations, mainly caused by the dinoflagellate genus Ceratium. At a couple of stations quite high densities of the fish killing species Karenia …

Algae report number 6, 2016

The species diversity among the dinoflagellates was high in the Skagerrak but it was the diatom species Proboscia alata that dominated the phytoplankton community. The Kattegat was dominated by chain forming diatom species. Proboscia alata were among the most abundant all over Kattegat with the …

Algae report number 5, 2016

Diatom species, often blooming during summer, were rather abundant in the Kattegat and Skagerrak samples. These summer species, as well as the diatom Chaetoceros danicus, also dominated in the samples from the chlorophyll fluorescence maxima. The flagellate Emiliania huxleyi is blooming in the …

Algae report number 4, 2016

The phytoplankton activity was rather low in the Kattegat and Skagerrak areas. Diatoms were common in the Kattegat though, with several species observed at variable abundances. The diversity was very low in the Skagerrak area. Chlorophyll fluorescence peaks at Fladen in the Kattegat and at Släggö …

Algae report number 3, 2016

The spring bloom was in its final phase in the Kattegat-Skagerrak areas. The chlorophyll concentrations were high and typical spring bloom diatoms were present, but the nutrients were completely or almost completely exhausted, which is why the bloom was predicted to end soon. Chlorophyll …

Algae report number 2, 2016

The phytoplankton diversity and cell concentrations were low in the open Skagerrak area while the beginning of a spring bloom was recorded at the inner station Släggö. The diatom Skeletonema marinoi was found in relatively high concentrations at all stations and this species is often dominating the …

Algae report number 1, 2016

All phytoplankton samples from the Skagerrak, the Kattegat and the Baltic Sea had low species diversities. All of the cell counts were low. No further detailed phytoplankton information will be presented in this report, only species lists and the chlorophyll diagrams.

Algae report number 10, 2015

The phytoplankton diversity and cell concentrations were low in the Skagerrak area. Small diatoms dominated. In the Kattegat the potentially toxin producing genus Pseudo-nitzschia spp dominated the community. The potentially harmful naked dinoflagellate Karenia mikimotoi was present. The integrated …

Algae report number 9, 2015

The phytoplankton community in the Skagerrak and the Kattegat was dominated by a small coccolithophore, Emiliania huxleyi, and a diatom, Pseudo-nitzschia spp. The potentially harmfull naked dinoflagellates Karenia
mikimotoi and Karlodinium veneficum were common and particularly at Släggö. The …

Algae report number 8, 2015

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 …
