Primary production and chlorophyll a concentrations were measured in March and May 1996, July and October 1997. The study was carried out in the coastal zone adjacent to the mouths of the Swina and Dziwna, which together drain over 80% of the waters carried by the river Odra, and in the open Pomeranian Bay. Chlorophyll a concentrations in the entire Pomeranian Bay varied between 0.8 and 16.5 mg m-3. The minimal daily in situ primary production measured in March was 19.3 mgC m-2 d-1, the July maximum was 1238.6 mgC m-2 d-1. The potential primary production ranged from 1.5 to 59.2 mgC m-3 h-1. The rate of photosynthesis expressed as the assimilation number (AN) varied from 0.3 to 6.6 mgC mgchl-1 h-1. The waters of the river Odra reinforce eutrophication in the coastal zone of the Pomeranian Bay. The photosynthetic rate there is usually higher than in open bay waters.
