Algal situation reports

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

Algae report number 5, 2012

The phytoplankton species diversity was low in both the Kattegat and the Skagerrak. Small flagellates dominated and especially different cryptomonads were common. The integrated (0-20m) chlorophyll concentrations were within normal in the Skagerrak and lower than normal in the Kattegat. The …

Algae report number 4, 2012

The phytoplankton diversity was very low in the Skagerrak and the Kattegat and cryptomonads were the most numerous. The integrated (0-20m) chlorophyll a concentrations were within normal in the Skagerrak and slightly below normal in the Kattegat. In the Southern Baltic a declining diatom bloom was …

Algae report number 3, 2012

The diatom spring bloom had ceased in The Kattegatt and Skagerrak areas. The total cell concentrations were very low and dominated by cryptomonads and ciliates. The integrated (0-20 meters) chlorophyll a concentrations were lower than normal in the Kattegatt and Skagerrak areas. The total cell …

Algae report number 2, 2012

An extensive spring bloom was observed at all phytoplankton stations in the Kattegat and Skagerrak areas. The diatom Skeletonema marinoi dominated the samples. The general species composition was more or less the same in the whole area, many diatom species in high cell numbers and a few …

Algae report number 1, 2012

Winter calm are the key words summarizing the phytoplankton situation throughout the sampling areas in the Western Sea and in the Baltic in January. Fragments from a Ceratium bloom was found at the Skagerrak coast (Släggö) and in the Kattegat. The diversity was very low. Cryptomonads were common in …

Algae report number 10, 2011

Overall the phytoplankton diversity was low at the Skagerrak sampling sites. The genus Ceratium that has been found in high amounts during autumn was observed with moderate cell numbers. The species diversity was a bit higher at the Kattegat sampling sites compared to the Skagerrak area, except on …

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 …
