Algal situation reports

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

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 …

Algae report number 5, 2017

Diatoms dominated along the Swedish west coast. The total cell concentrations were overall quite low. Chlorophyll concentrations were within normal at most stations except in the northern stations Å15 and Å13 where they were above normal for the month. The flagellate Pseudochattonella spp.*, …

Algae report number 4, 2017

Chlorophyll fluorescence maxima and some high measured chlorophyll concentrations in the Kattegat and Skagerrak areas were mainly caused by the flagellate Pseudochattonella spp.*, potentially harmful for fish. The flagellate has been observed during the two previous cruises as well. The cells were …

Algae report number 3, 2017

The phytoplankton genus Pseudochattonella spp.*, which is potentially harmful to fish when in high abundancies, was still blooming in the Kattegat and Skagerrak areas during the March cruise. The genus caused chlorophyll fluorescence maxima at several stations. The diatom spring bloom seems smaller …

Algae report number 2, 2017

The phytoplankton genus Pseudochattonella spp.*, which is potentially mortal to fish when in high abundancies, was present with quite high cell numbers at all of the phytoplankton monitoring stations in the Kattegat and Skagerrak area. Fluorescence maxima at Anholt E, Å13 and Å15 were mainly caused …
