Lorenz Z., Nakonieczny J., Ochocki S., Renk H., 1991. Primary production and chlorophyll in the Gulf of Gdańsk in 1987-1988. Acta Ichthyol. Piscat. 21 (Suppl.): 117-124.
The paper presents data on primary production and chlorophyll a concentrations at two stations located in the Gulf of Gdańsk (Baltic Sea). The primary production in 1981 was much higher than the mean values for the region, observed in other years when the production was 125-200 g C/m2a. Our observations show the primary production in the Puck Bay to be approximately two times that in offshore waters of the Gdańsk Deep. The chlorophyll contents decrease along the Vistula estuary-Gdańsk Deep transect.
