Algal situation reports

This report presents the results from two September cruises. A small diatom bloom was proceeding at the Skagerrak coast and in the Kattegat area during the second cruise. In open Skagerrak, the plankton flora was scarce with a few small species in low cell numbers. The integrated chlorophyll a …

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 …

AlgAware number 7 is split in two parts because the July cruise is divided into two. This report, part 2, presents phytoplankton analysis from the Skagerrak, the Kattegat and the southwestern part of the Baltic Proper. Phytoplankton analyses have partly been made on board, partly on land, at the …

AlgAware number 7 is split in two parts because the July cruise is divided into two. This report, part 1, presents phytoplankton analysis from the Baltic Sea. The second cruise is planned to start 30th of July and will cover the Skagerrak, Kattegat and the southern Baltic. Phytoplankton analysis …

The AlgAware report No 6 is divided in PART 1 and PART 2 because the expedition in June was divided in two cruises. This report presents phytoplankton analyses from the southern Baltic Sea and the Swedish West coast.

The AlgAware report No 6 will be divided in PART 1 and PART 2 because the expedition in June is divided in two cruises. This report present phytoplankton analyses from the Baltic Sea. The Aphanizomenon flos-aquae dominated southeast part of the Baltic and three species from the genus …

Low cell numbers were found at all stations from the Skagerrak-Kattegat area. The species diversity was low especially in the samples from the Kattegat area. Small flagellates of different sorts were the most common. The samples were very similar, the phytoplankton diversity was very low. The cell …

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. …

Remnants of the spring bloom were found in the surface water at both stations in the Skagerrak. The chlorophyll fluorescence maxima indicated that the bloom was sinking down considering they were found at approximately 15 meters. Diatoms dominated in the surface water and Skeletonema marinoi and …

The cell concentrations were low at all stations in the Baltic Sea and at the Swedish west coast except at Å17 in the Skagerrak. The species diversity was relatively high at the Swedish west coast and low in the Baltic Sea. The integrated (0-20 m) chlorophyll a concentrations were within normal at …
