Algal situation reports

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

Algae report number 11, 2022

The phytoplankton diversity and the total cell numbers were relatively high at most stations along the Swedish west coast. The only exception was Å17 where total cell numbers were low. Diatoms dominated overall in cell numbers and Pseudosolenia calcar-avis was common in the Kattegat. The …

Algae report number 10, 2022

The phytoplankton diversity was very low. The number of species at Släggö was somewhat enhanced compared to the other Skagerrak and Kattegat stations, but the total cell numbers were low in the entire area. At Släggö, moderate cell numbers of the silicate flagellate Octactis speculum and its naked …

Algae report number 9, 2022

The phytoplankton diversity was high at all stations along the Swedish west coast. Diatoms dominated in cell numbers and Pseudosolenia calcar-avis was common. In Skagerrak the potentially toxic dinoflagellate Dinophysis acuta* was common. The coccolithophore Emiliania huxleyi was found in high cell …

Algae report number 8, 2022

The phytoplankton diversity and total cell counts were low in the Kattegat and Skagerrak areas, except at Släggö where the diversity was a bit higher. The toxic species Dinophysis acuta* was found in relatively high cell numbers at Släggö. The diatom Proboscia alata was common at all stations along …

Algae report number 7, 2022

The analyses were made onboard the ship R/V Svea during the cruise. Water from integrated samples or discrete depths were filtrated down to filters with 5μm pore size. The method is more suitable for identifying larger and more robust cells whereas smaller cells or fragile cells are …

Algae report number 6, 2022

The phytoplankton diversity was high whilst the total cell counts were low in the Kattegat and Skagerrak areas, except at Å17 where the diversity was low as well as the cell numbers. The coccolithophorid Emiliania huxleyi was numerous and Dactyliosolen fragilissimus was the most abundant diatom …

Algae report number 5, 2022

In the Skagerrak and Kattegat areas both cell abundance and diversity were low and small cells dominated the samples. Different ciliates and naked dinoflagellates were most common together with cryptomonads. At Å17 some cells of the coccolithophore Emiliania huxleyi were present. The integrated …

Algae report number 4, 2022

In the Skagerrak, both cell abundance and diversity were low at Å17, the diversity was however higher at Släggö. At Släggö the toxin producing dinoflagellate Dinophysis norvegica* was present in quite high cell numbers. In Kattegat, at the first sampling occasion at Anholt E the water was …

Algae report number 3, 2022

Both stations in the Skagerrak had high total cell abundances and high biodiversity. Different species of diatoms dominated the coastal phytoplankton community, of which the common chain forming diatom Skeletonema marinoi was the most abundant. The off-shore station was, however, dominated by the …

Algae report number 2, 2022

Both stations in the Skagerrak had low total cell abundance and low biodiversity. No indication of an upcoming spring bloom was found. Small cells dominated and different cells of cryptomonads were most commonly found. The diatom Skeletonema marinoi, commonly dominating the spring bloom was found …
