Algal situation reports

There were several phytoplankton species with high cell numbers in the samples from the Skagerrak and Kattegat area, mainly at the coastal stations Släggö in the Skagerrak and N14 in the Kattegat. The integrated (0-20 m) chlorophyll a concentrations were normal for this month. Chlorophyll a maxima …

In the Skagerrak, the phytoplankton community was rather low in diversity. In Kattegat the species diversity was a bit higher. A fluorescence maxima was found at almost all stations and these maxima were dominated by different species of the dinoflagellate genus Ceratium In the Baltic proper, …

In the Skagerrak, the phytoplankton samples were rather low in diversity and fluorescence maxima were dominated by the dinoflagellate Ceratium tripos. The Kattegat fluorescence maxima samples were dominated by diatoms, except at Fladen where several Ceratium species dominated.

In the Baltic, the …

The Kattegat and the southern part of the Skagerrak were dominated by an unidentified flagellate. It has also been recorded in the Danish monitoring programme. In the Skagerrak, the dinoflagellate Peridiniella danica and large cells from the diatom Cerataulina pelagica were common. The unidentified …

This report presents the results from the cruise from the end of February to the beginning of March. The species diversity and cell concentrations were low in the Baltic Sea and at the majority of the stations visited in the Skagerrak and the Kattegat. The most species rich samples were found at …

A new cooperation between SMHI and the Finnish SYKE has started. This is the first AlgAware with data from samplings with the Finnish ship R/V Aranda. All phytoplankton samples from the Skagerrak, the Kattegat and the Baltic Sea contained low species diversities and all of the cell counts were …

This report presents the results from the first of two December cruises. The Baltic Proper and the Bothnian Bay were visited. Merely three phytoplankton stations were sampled due to the stormy weather in the area. The potentially harmful flagellate Prymnesium cf. polylepis was present at all …

This report presents the results from two November cruises. The Baltic Proper was visited in the beginning of the month, and the Skagerrak, the Kattegat and Southwestern Baltic areas in the end. The number of species and cell numbers were low in the Skagerrak area. In the Kattegat the species …

This report presents the results from two October cruises. The Skagerrak, the Kattegat and Southwestern Baltic areas were visited in the beginning of the month, and the Baltic Proper at the end. The number of species and cell numbers were very low in the Skagerrak and the Kattegat. The …

This report presents the results from two September cruises. A small diatom bloom was proceeding at the Skagerrak coast and in the Kattegat area during the second cruise. In open Skagerrak, the plankton flora was scarce with a few small species in low cell numbers. The integrated chlorophyll a …
