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 stations. In the Kattegat the species diversity was rather high and dominated by diatoms. The total cell numbers were however low. The chlorophyll concentrations were normal for this month at all stations. The few species found at BY2 and BY4 in the southern Baltic Sea had low cell numbers. The integrated chlorophyll concentrations, 0 - 20 m, were below normal for this month.
