This report offers results from two August cruises. The phytoplankton diversity was low in the Skagerrak and the Kattegat areas. Merely small species were found in high cell numbers, i.e. the coccolithophorid Emiliania huxleyi, known to colour the ocean turquoise when blooming. The chlorophyll a Last updated: Apr 23, 2014

The Skagerrak, the Kattegat, The Sounds and the Baltic Proper was visited during the cruise, as a part of the National Marine Monitoring Programme of Sweden. Sea surface temperature was within normal range for the season at all visited stations.  Concentrations of phosphate and dissolved inorganic Last updated: May 04, 2023

Several spring bloom diatom species were present in the phytoplankton samples from the Skagerrak-Kattegat area, reminding us of the past bloom. The diatom Rhizosolenia hebetata was common at most stations and Skeletonema marinoi was common at one of the Anholt E visits. Cell counts were mostly low. …

A new agreement with the Swedish Coastguard caused a shorter cruise, consequently only the Swedish west coast and parts of the southern Baltic Proper (Arkona and Bornholm Basins) were visited. The species diversity was low and the cell density was high in the Skagerrak, small flagellates and …

a concentrations were lower than normal in most parts of the Skagerrak and the Kattegat. Chlorophyll a concentrations at the Arkona Deep were lower than normal and at the Bornholm Deep higher than normal. This report is a shortened version because of lack of events in the phytoplankton world. Last updated: Apr 23, 2014

-aquae was quite common in the sample. At BY5, the setting differed, the number of species was low and merely one diatom species was observed. The integrated (0-20 m) chlorophyll a concentrations were low, but within normal for this month in all sampling areas. This report is a shortened version because of Last updated: Apr 23, 2014

The phytoplankton diversity was very low in the Skagerrak and the Kattegat and cryptomonads were the most numerous. The integrated (0-20m) chlorophyll a concentrations were within normal in the Skagerrak and slightly below normal in the Kattegat. In the Southern Baltic a declining diatom bloom was …

at the remaining stations. Integrated chlorophyll a is therefore missing at some stations. http //www.smhi.se/oceanografi/oce_info_data/reports/cruise/exp_0912eng.pdf Last updated: Apr 23, 2014

Overall the phytoplankton diversity was low at the Skagerrak sampling sites. The genus Ceratium that has been found in high amounts during autumn was observed with moderate cell numbers. The species diversity was a bit higher at the Kattegat sampling sites compared to the Skagerrak area, except on …
