Algrapport nummer 7, 2002

The amount of phytoplankton in the open Skagerrak is small, whereas the coastal station showed a rich planktonflora dominated by Ceratians. Large amounts of dinoflagellates with a dominance of Ceratium furca and Lingulodinium polyedrum were found in the Kattegat. There are still blue-green algae, Aphanizomenon sp. and Nodularia spumigena present in the south part of the Baltic Sea and between Gotland and Öland, although the amounts are much smaller than a few weeks ago. Zooplankton and especially tinntinnids were common.
