Algal situation reports

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

Algae report number 9, 2012

A new agreement with the Swedish Coastguard caused a shorter cruise, consequently only the Swedish west coast and parts of the southern Baltic Proper (Arkona and Bornholm Basins) were visited. In addition, the weather situation in Skagerrak caused that Å17 was only partially sampled. The species …

Algae report number 7, 2012

The species diversity was quite low in both Skagerrak and Kattegatt, the only exception was the first sampling occasion at Anholt E. High densities of the calcium flagellate Emiliania huxleyi was recorded. This species normally appear in higher densities in late spring and early summer in this …

Algae report number 6, 2012

Despite the great secchi depth, quite high phytoplankton cell numbers and many species were found at the Skagerrak coast. In the open sea area, phytoplankton were more scarce. In the Kattegat the diatom Dactyliosolen fragilissimus and the cyanobacterium Anabaena sp. were abundant. In the Baltic …

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 …
