Algal situation reports

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

Algae report number 9, 2011

The integrated (0-20 meters) chlorophyll a concentrations were normal for the season at all Skagerrak sites. Chlorophyll a concentrations were however above normal in Kattegat at N14 and on the second sampling occasion at Anholt E. The phytoplankton community in the Skagerrak and the Kattegat was …

Algae report number 8, 2011

The integrated (0-20 meters) chlorophyll a concentrations were normal for the season at most of the Skagerrak and Kattegat sampling sites. The phytoplankton species diversity and cell density were very low as last month. Naked dinoflagellates (10-20 μm) and cryptomonads were still most abundant …

Algae report number 6, 2011

This report only comprises results from analysis of phytoplankton. An extended version containing results from chlorophyll a measurements will be available in the beginning of next week. A quite scarce community was found at the outer station Å17 in the Skagerrak area while the inner station Släggö …

Algae report number 5, 2011

The phytoplankton diversity was generally low in the Skagerrak and Kattegat areas. Small species like Cryptomonads and Chrysochromulina spp. dominated the samples. A few diatoms were found with moderate cell numbers at Släggö (Skagerrak coast) and in the Kattegat. The dinoflagellate Prorocentrum …

Algae report number 4, 2011

The phytoplankton community in both Skagerrak and Kattegat areas comprised mainly of small flagellates. The only exception was Släggö, the inner site in the Skagerrak where the diatom Dactyliosolen fragilissimus was found in highest abundance. The coccolithophorid Emiliana huxleyi was dominating at …

Algae report number 3, 2011

The genus Dinobryon dominated in the Skagerrak area, the dominance was especially pronounced at the outer station Å17. Low chlorophyll a values clearly indicated that the spring bloom had now ended. Low chlorophyll a concentrations were also recorded in the Kattegat area. Few species were recorded …

Algae report number 2, 2011

The phytoplankton flora was poor in the Skagerrak area and small flagellated species dominated the samples. The integrated (0-20m) chlorophyll concentrations were low but within normal for this month. Traces from the spring bloom were obvious in the Kattegat area and the species Pseudochattonella …

Algae report number 1, 2011

The plankton community was dominated by diatoms in both Skagerrak and Kattegat and Skeletonema marinoi dominated at all stations. Different cryptomonads such as Teleaulax were also common. The chl a measurements were overall low and no tendency of a forthcoming spring bloom could be seen. A bit …

Algae report number 13, 2010

Relatively few cells were found at all stations which is normal for the season. A quite diverse community but with few cells of each species was however found in the Skagerrak area. The diatom genus Pseudo-nitzschia was found in high abundance at the outer station in Skagerrak (Å17) and at both …

Algae report number 12, 2010

The major differences between the Skagerrak and Kattegat areas during the latest cruise were the high cell numbers of the diatoms Pseudosolenia calcar-avis and Pseudo-nitzschia spp. in the Kattegat phytoplankton samples. The species’ were present in the Skagerrak as well but in low cell numbers. …
