Popis: The seasonal dynamics of the nanophytoplankton community (pelagic algae 2–20 μm) was studied at a location in the Southern Bight (North Sea) from October 1993 through May 1994. During the study period the cell number and biomass of the nanoalgae varied between 10 5 –10 6 cells dm −3 and 16–300 μg wet weight dm −3 . Several ecological events seem common to the boreal coastal nanophytoplankton communities in the winter–spring period. These are: (1) abrupt fall in abundance at the beginning of winter (late October–early November); (2) winter minimum (December–March); (3) steady increase in cell number and biomass (April–May); followed by (4) the spring maximum occurring usually in May.
