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 …

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, …

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 …

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 …

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 …

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 …

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 …

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 …

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 …
