Cyanobacterial blooms in the Gulf of Finland 1992

Latitude from 59° 10 min to 59° 42 min and longitude from 22° 11 min to 23° to 40 min

Phytoplankton taxonomic biomass in water bodies; Chlorophyll pigment concentrations in water bodies; Wind strength and direction; Bacterial growth; Nitrate concentration parameters in the water column; Phytoplankton taxonomic abundance in water bodies; Phosphate concentration parameters in the water column; Primary production in the water column; Salinity of the water column; Density of the water column; Temperature of the water column; Zooplankton taxonomy-related abundance per unit volume of the water column; Dissolved inorganic carbon production and respiration in the water column; Bacteria taxonomic abundance in water bodies

Fluorometers; CTD; discrete water samplers; autoanalysers; liquid scintillation counters

The cruise consisted of samplings at 25 fixed stations organized in a grid. Each station was visited altogether 4 times. CTD was measured at 25 stations, vertical profiles of nutrients were sampled at 15 stations 1-10 times. Biological variables were measured form an integrated sample representing the upper mixed layer at 3 stations. Water masses in the surface layer were mapped with a flow-through system measuring salinity, temperature and fluorescence.
