Algal situation reports

Reports from SMHIs offshore sampling programme, which describe the algal situation in marine waters surrounding Sweden.

Algae report number 4, 2013

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. The...

Algae report number 3, 2013

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 Detonula...

Algae report number 2, 2013

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 Å17...

Algae report number 1, 2013

The cell concentrations were low in all sampling stations at the Swedish West coast and in the Baltic Sea. The species diversity was higher in the Kattegat and Skagerrak areas than in the Baltic Sea. The species diversity was highest among the dinoflagellates although it seems like the diatom spring...

Algae report number 11, 2012

This report is based on two cruises in December, covering the Baltic Sea and the Swedish West coast sampling stations. Typical winter situations were registered in the Kattegat and Skagerrak areas. The number of species was low, and the dinoflagelllate genus Ceratium and small flagellates were the...

Algae report number 10, 2012

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 cryptomonads...

Algae report number 9, 2012

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. In addition, the weather situation in Skagerrak caused that Å17 was only partially sampled. The species diversities...

Algae report number 8, 2012

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 number of species was quite high in the coastal Skagerrak waters (Släggö), but the cell numbers were...

Algae report number 7, 2012

The species diversity was quite low in both Skagerrak and Kattegatt, the only exception was the first sampling occasion at Anholt E. High densities of the calcium flagellate Emiliania huxleyi was recorded. This species normally appear in higher densities in late spring and early summer in this area....

Algae report number 6, 2012

Despite the great secchi depth, quite high phytoplankton cell numbers and many species were found at the Skagerrak coast. In the open sea area, phytoplankton were more scarce. In the Kattegat the diatom Dactyliosolen fragilissimus and the cyanobacterium Anabaena sp. were abundant. In the Baltic Sea...
