Modeling runoff to the Baltic Sea

Article Abstract:

Modeling runoff to the Baltic Sea using a large-scale hydrologic model with macroscale parameters is discussed. Total daily runoff reflected 25 subbasins of varied size. The model is used for cooperative research involving oceanographic and meteorological aspects for the Baltic Sea Experiment and the Swedish Regional Climate Modelling Programme.

Internal nutrient fluxes counteract decreases in external load: the case of the estuarial eastern Gulf of Finland, Baltic Sea

Article Abstract:

Research indicates that the low nitrogen-to-phosphorus ratio of sediment efflux in the Gulf of Finland plays a significant role in nitrogen limitation of Gulf primary production. Phosphorus concentrations are due to an increase in internal loading brought about by low oxygen conditions in the water/sediment interface.

Recent changes in trophic state of the Baltic Sea along SW coast of Finland

Article Abstract:

A 30-year chlorophyll alpha data set from the western Gulf of Finland is presented. The trophic state of this area showed an increasing trend from the 1970s to the 1980s but then remained unchanged in the 1990s.
