Algal situation reports

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

Algae report number 5, 2010

The integrated (0-20 meters) chlorophyll a concentrations were low at all of the Skagerrak sampling sites, which is normal for the season. The species diversity was quite divers low at the Skagerrak stations but with low abundance of each species. Only a few species of diatoms were found and the phytoplankton...

Algae report number 4, 2010

During the mid April phytoplankton sampling the species diversity was very low at the Skagerrak stations. Whereas the total cell counts were the highest one month earlier at Å17, the situation was the opposite now with no diatoms. A few ciliates, small flagellates and dinoflagellates were present. The...

Algae report number 3, 2010

The phytoplankton samples from the Skagerrak station Å17 had the highest diversity of the plankton stations in the Western Sea in mid-March. Diatoms were the most frequent and the diatom Leptocylindrus danicus the most numerous species. At Släggö and at the Kattegat stations the species diversity was...

Algae report number 2, 2010

Extraordinarily high levels of chlorophyll a and high cell numbers were found in the Skagerrak and Kattegat areas in mid January. Fluorescence maxima were found at about 10 meters depth at several stations. The diatoms Skeletonema costatum, Pseudo-nitzschia delicatissima-group and Thalassiosira nordenskioeldii...

Algae report number 1, 2010

Extraordinarily high levels of chlorophyll a and high cell numbers were found in the Skagerrak and Kattegat areas in mid January. The diatoms Skeletonema costatum, Pseudo-nitzschia delicatissima-group and Thalassiosira nordenskioeldii dominated the phytoplankton samples. P. delicatissima-group was found...
