chlorophyll concentrations (0–10 m and 0–20 m) were within normal for this month at all stations. Diversity and cell abundance of phytoplankton were very low in the Baltic Sea, with mostly smaller cells such as Cryptomonadales and smaller Gymnodiniales. The centric diatom Actinocyclus octonarius was present Last updated: Feb 27, 2024

The species diversity was high in the Kattegat when considering the season but the total cell numbers were low. In the Skagerrak the diversity was a bit lower. Only Släggö could be sampled in Skagerrak during this cruise. The Plankton community along the Swedish west coast had a traditional winter Last updated: Jan 30, 2024

mixture of the genus Tripos but also the genus Pseudo-nitzschia. Closer to the coast both the Tripos spp. and Proboscia alata was represented in the maxima. No clear surface accumulations of cyanobacteria were found in the Baltic Sea during this expedition. This was most likely due to relatively high wind Last updated: Jul 17, 2023
