A new cooperation between SMHI and the Finnish SYKE has started. This is the first AlgAware with data from samplings with the Finnish ship R/V Aranda. All phytoplankton samples from the Skagerrak, the Kattegat and the Baltic Sea contained low species diversities and all of the cell counts were low Last updated: Apr 23, 2014

Sea The phytoplankton situation was modest in the Baltic Sea and besides the species lists there is nothing more to report this month. Colonies of pico cyanobacteria were abundant at BY15 and BY25.

This report only comprises results from analysis of phytoplankton. An extended version containing results from chlorophyll a measurements will be available in the beginning of next week. A quite scarce community was found at the outer station Å17 in the Skagerrak area while the inner station Släggö Last updated: Apr 23, 2014

report. The Kattegat Anholt E 12th and 13th of May The total cell number was low and dominated by small cells of unknown taxonomic place. Among the larger cells the diatoms Proboscia alata, Skeletonema marinoi and Guinardia delicatula were found in highest cell numbers. The coccolithophore Emilia huxleyi Last updated: May 28, 2019

counts were also quite low. The phytoplankton community was dominated by many cryptomonads. The chlorophyll a concentrations were low but within average. The stations in the Baltic Sea were in general dominated by dinoflagellates, ciliates, Prymnesiales and small flagellates. The areas east and south of Last updated: Apr 23, 2014

All phytoplankton samples from the Skagerrak, the Kattegat and the Baltic Sea had low species diversities. All of the cell counts were very low. The integrated chlorophyll concentrations were normal at the Baltic stations and below normal at the Skagerrak and Kattegat stations. No details will be Last updated: Feb 27, 2018

diatoms and dinoflagellates. Species of Dinophysis and Chaetoceros were most abundant in these peaks. The integrated (0-20 m) chlorophyll a concentrations in the Baltic Sea where within normal at most of the stations except for BY32 and BY2 where concentrations were higher than normal as well as at BY4 Last updated: Jun 25, 2018
