Algal situation reports

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

Algae report number 3, 2020

At Å17, the most westerly Skagerrak station, the diversity and the total cell concentration were both high and presented a spring bloom situation. At Släggö, at the coast, the phytoplankton diversity and chlorophyll concentrations were a bit lower but still indicated a spring bloom. Diatoms …

Algae report number 2, 2020

A number of stations were cancelled during the cruise. Some because of the bad weather, others due to the fact that parts of the anchoring from a buoy got stuck in one of the ships propellers, which caused cancellation of the cruise and a safety stop in Oxelösund prior to the detour to Lysekil. At …

Algae report number 1, 2020

Only half of the amount of stations that were planned to be sampled during the cruise were actually visited due to engine problems which caused cancellation of the remaining cruise. At Å17, the most westerly Skagerrak station and at Släggö at the coast, the phytoplankton diversity and chlorophyll …

Algae report number 11, 2019

The total cell concentrations in the open Skagerrak and in the Kattegat were relatively high. The potentially toxic diatom genus Pseudo-nitzschia * dominated at all stations. The coccolithophorid Emiliania huxleyi was common among the small cells at all stations. The integrated chlorophyll …

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 …
