Algal situation reports

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

Algae report number 10, 2019

The total cell concentrations in the open Skagerrak and in the Kattegat were low and dominated by small cells. The coccolithophorid Emiliania huxleyi was found with the highest cell numbers. The potentially toxic diatom genus Pseudo-nitzschia* was common at all stations along the west coast. The …

Algae report number 9, 2019

Due to strong winds the Skagerrak could not be sampled. N14 Falkenberg and Anholt E in the Kattegat were sampled although Anholt E was visited only once during the cruise. The total cell numbers and the biodiversity were low at both stations and were dominated by small cells. The coccolithophorid …

Algae report number 8, 2019

All stations along the Swedish West coast had a domination of small cells. The coccolithophore Emiliania huxleyi dominated in cell numbers at more or less all stations. Different species of the order cryptomonadales were also common. In the Kattegat the larger cells were dominated by the diatom …

Algae report number 7, 2019

The diatom Proboscia alata was found in high concentrations in the hose samples (0-10m) taken at all stations in the Skagerrak and the Kattegat area. Distinct chlorophyll fluorescence maxima were noted at 25-30 meters at most stations. Theses maxima were all dominated by different speciesfrom the …

Algae report number 6, 2019

The phytoplankton diversity was generally speaking low in the Skagerrak and Kattegat areas, although the number of species and the total cell numbers were higher in the Skagerrak in comparison. The coccolithophorid Emiliania huxleyi was abundant, especially at Släggö. The chlorophyll concentrations …

Algae report number 5, 2019

Most stations along the Swedish West coast had a domination of small cells. The coccolithophore Emiliania huxleyi was common at all stations and even dominated in cell numbers at Å17. In Kattegat remnants of the spring bloom could be seen with higher cell numbers of the diatoms Skeletonema marinoi …

Algae report number 4, 2019

A post spring bloom situation was observed at most of the phytoplankton stations in the Skagerrak and Kattegat areas with low total cell counts and relatively high numbers of heterotrophic species like the dinoflagellate Peridiniella danica. At N14 though, a Pseudochattonella bloom was ongoing …

Algae report number 3, 2019

In the Skagerrak and the Kattegat the biodiversity in the phytoplankton community was low and the chlorophyll concentrations were normal. The spring bloom was in its final days with quite high amounts of Guinardia delicatula and a few chains of Skeletonema marinoi. Furthermore, flagellates, such as …

Algae report number 2, 2019

The biodiversity and total cell concentrations were both low in Skagerrak. The spring bloom forming species Skeletonema marinoi was found in highest cell numbers. In the Kattegat however, the species diversity and total cell numbers were high. Diatoms dominated and S. marinoi was found in highest …

Algae report number 1, 2019

At Å17, the most westerly Skagerrak station and at Släggö near the coast, the phytoplankton diversity and chlorophyll concentrations were low, which is normal for this month. In the Kattegat however, the species diversity was high and some diatoms were found in very high cell numbers. The …
