Algal situation reports

Both stations in the Skagerrak had high total cell abundances and high biodiversity. Different species of diatoms dominated the coastal phytoplankton community, of which the common chain forming diatom Skeletonema marinoi was the most abundant. The off-shore station was, however, dominated by the …

Both stations in the Skagerrak had low total cell abundance and low biodiversity. No indication of an upcoming spring bloom was found. Small cells dominated and different cells of cryptomonads were most commonly found. The diatom Skeletonema marinoi, commonly dominating the spring bloom was found …

Due to a case of covid-19 onboard the R/V Svea, the cruise had to stop at Bornholm in the Southern Baltic and turn back to the home port, Lysekil. All Kattegat and Skagerrak stations were sampled. The phytoplankton species diversity was very low with low total cell numbers at the Skagerrak …

The species diversity was high at most stations along the west coast. The total cell numbers varied but quite many stations had low numbers. Diatoms dominated in the samples but the order Dictyocales including the species Octactis speculum was common. The coccolithophore Emiliania huxleyi was found …

The species diversity was high at three of four stations int the Kattegat and Skagerrak areas and the highest at the Kattegat stations. Diatoms dominated the samples, but the individual cell numbers were relatively low or moderate. The integrated chlorophyll concentrations were within normal for …

Species diversity and cell numbers were low at Å17, but high at the other three stations. Å17 had mostly small species of dinoflagellates, such as Gymnodiniales, Heterocapsa rotundata and Karenia mikimotoi*. The other stations had both diatoms and dinoflagellates in various sizes, as well as some …

The species diversity was overall high at most stations sampled along the west coast even if the total cell numbers were not. Different diatoms were found in relatively high cell numbers and for example the genus Pseudo-nitzschia* was common at all stations. Among the dinoflagellates, Karenia …

The analyses were made on bord the ship Svea during the cruise. Water from integrated sampels or discrete depths were filtrated down to filters with 5μm pore size. The method is most suitebale for identifying larger and more robust cells whereas smaller cells and fragile cells are difficult to …

All stations along the west coast had a domination of diatoms to some extent. Most common was Dactyliosolen fragilissimus. The dinoflagellates were not common and mostly represented by the genus Tripos. The coccolithophorid Emiliania huxleyi was found in relatively high numbers at several stations. …

All stations along the west coast had a domination of diatoms and far most common was Skeletonema marinoi. Among the dinoflagellates the genus Tripos was most common. Chlorophyll concentrations at all stations were normal for this month. Worth mentioning is that Anholt E was visited twice. On both …
