Algal situation reports

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

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 …

Algae report number 8, 2018

The species diversity was rather high at most stations along the Swedish west coast. The total cell numbers were rather low. Diatoms dominated and the genus Pseudo-nitzschia* was found in then highest concentrations. The coccolithophorid Emiliania huxleyi was abundant at most stations.
The …

Algae report number 7, 2018

The species diversity was fairly high in the Kattegat and at Släggö at the Skagerrak coast. The total cell numbers were low and the most numerous species were the dinoflagellate Prorocentrum compressum and the diatom Pseudosolenia calcar-avis. The coccolithophorid Emiliania huxleyi was present in …

Algae report number 6, 2018

This cruise was not a full cruise with phytoplankton sampling at only three west coast stations and three stations in the Baltic Sea. The west coast stations Släggö and Anholt E displayed relatively high biodiversity. The coccolithophore Emiliania huxleyi was found at high cell numbers at both …

Algae report number 5, 2018

This sampling occasion was not a full cruise with all phytoplankton stations, only one west coast phytoplankton station and six in the Baltic Sea were sampled. The west coast station (Anholt E), displayed an autumn bloom community with several species of dinoflagellates, as well as some diatoms, …

Algae report number 4, 2018

The integrated (0-10 m and 0-20 m) chlorophyll a concentrations were low but within normal for this month at all stations in the Kattegat and Skagerrak areas, except for Å15 where chlorophyll concentrations were higher than normal. The chlorophyll fluorescence maxima in these areas were caused by …

Algae report number 3, 2018

The integrated (0-20 m) chlorophyll concentrations were within normal for this month at most stations in the Kattegat and Skagerrak and chlorophyll fluorescence maxima in these areas were caused by diatoms. The diatoms Rhizosolenia spp., Chaetoceros decipiens and Thalassionema nitzschioides were …

Algae report number 2, 2018

All of the stations surrounding Gotland and the stations in the Eastern Baltic could not be visited due to the bad weather conditions. The spring bloom was ongoing in the Kattegat and Skagerrak areas at the time of the cruise in March. Diatoms dominated the samples and chlorophyll concentrations …

Algae report number 1, 2018

All phytoplankton samples from the Skagerrak, the Kattegat and the Baltic Sea had low species diversities. All of the cell counts were very low. The integrated chlorophyll concentrations were normal at the Baltic stations and below normal at the Skagerrak and Kattegat stations.

No details will be …
