Algal situation reports

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

Algae report number 3, 2015

In the coastal area of the Skagerrak the nutrient- and cell concentrations were low compared to the open Skagerrak where the diatom spring bloom was ongoing. In the Baltic Sea the cell density was generally low but at the Arkona Basin the spring bloom had started. The integrated (0-10 m) …

Algae report number 2, 2015

The cell concentration was very low at Å17 in the open Skagerrak. The chlorophyll fluorescence measurements and the high nutrient concentrations showed that the spring bloom had not yet started here. The diatom spring bloom was ongoing in the Kattegat and at Släggö on the Skagerrak coast. The …

Algae report number 1, 2015

The diatom spring bloom had started at the southern Kattegat station, Anholt E. Due to the storm Egon, the January cruise could not visit the Skagerrak area this month, as well as several stations in the Baltic.

The species diversities and cell densities were very low in the Baltic Sea. The …

Algae report number 8, 2014

The diversity was high and diatoms dominated the phytoplankton community in the Kattegat and the Skagerrak. A flagellated cell that most likely is Vicicitus globosus or a naked stage of Dictyocha speculum or D. fibula, was common in this area.

The species diversity and cell density was generally low …

Algae report number 7, 2014

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 …

Algae report number 6, 2014

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, …

Algae report number 5, 2014

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 …

Algae report number 3, 2014

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 …

Algae report number 2, 2014

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 …

Algae report number 1, 2014

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 …
