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

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 …

Algae report number 10, 2017

The species diversity was high in the Skagerrak and Kattegat areas during the November cruise. The largest number of species were found at Släggö in the Skagerrak. Diatoms were especially species rich amongst which Pseudo-nitzschia was found to have the highest cell numbers. Dinoflagellates and …

Algae report number 9, 2017

Due to rough weather conditions and technical problems onboard the M/V Aura, which replaces the R/V Aranda, several stations could not be visited during the October cruise. This is also why as many chlorophyll diagrams are missing.

The species diversity was high in the Kattegat phytoplankton …

Algae report number 8, 2017

The phytoplankton samples from the Skagerrak and Kattegat areas had rather high species diversity and the largest number of species, dominated by diatoms, were observed at Släggö in the Skagerrak. At Släggö there was also high numbers of the naked stage of the flagellate genus Dictyocha, which …

Algae report number 7, 2017

The diatom Proboscia alata was found in high concentrations at all stations in the Skagerrak and in Kat-tegat. The species diversity was generally low at all west coast stations. One or two chlorophyll maxima were found at all stations, mainly caused by P. alata and also by different species …

Algae report number 6, 2017

The phytoplankton diversity was generally low in the Kattegat and Skagerrak areas. Rather small chlorophyll fluorescence peaks were caused by a few diatom species and the dinoflagellate genus Ceratium. The summer bloom of cyanobacteria was ongoing in the Baltic Sea. Aphanizomenon flos-aquae …
