Paul; Huse, Geir; Stiansen, Jan Erik; Ådlandsvik, Bjørn; Vikebø, Frode; Asplin, Lars; Sundby, Svein (ICES CM documents, Working paper, 2006)Abstract The NORWECOM ocean model system implemented with the ROMS ocean circulation model has been run to simulate conditions over the last 25 years for the North Atlantic. Modelled time series of volume fluxes, primary ... -
Environmental status of the Skagerak and North Sea 2000
Skogen, Morten D.; Svendsen, Einar; Søiland, Henrik (Fisken og havet, Research report, 2002)An environmental status for year 2000 of the North Sea and Skagerrak has been done based on outputs from a biophysicaf model (NORWECOM). The model results suggests that in year 2000 the mean annua1 primary production in ... -
Environmental status of the Skagerrak and North Sea 2001
Skogen, Morten D.; Søiland, Henrik; Svendsen, Einar (Fisken og havet, Research report, 2003)A coupled physical, chemical and biological ocean model (NORWECOM) is used to sirnulate 2001 in the North Sea and Skagerrak. The results from this simulation is used to make an environmental status for that year. In the ... -
Eutrophication issues attacked by a numerical model of the North Sea/Skagerrak
Skogen, Morten D.; Søiland, Henrik; Svendsen, Einar (ICES CM documents, Working paper, 2003)Several issues of eutrophication in the North Sea and Skagerrak have been attacked using a three dimensional ecological model, NORWECOM. The focus have been on two different years, 2000 and 2001, their characteristics ... -
Eutrophication Scenaria from Reduced Nutrient Loads to the North Sea
Skogen, Morten D.; Søiland, Henrik; Svendsen, Einar (ICES CM documents, Working paper, 2003)The environmental effects of river nutrient loads to the North Sea have been investigated using a numerical biophysical model, NORWECOM, to perform different reduction scenarios. The simulations demonstrate that the river ... -
Factors determining the year-class strength of Norwegian spring spawning herring
Krysov, Alexander; Bjørke, Herman; Svendsen, Einar (PINRO-IMR Symposium, Conference object, 1995)More than 30 years of Russian and Norwegian data on spring-spawning herring larvae along the coast of Norway has been investigated and analyzed together with different environmental parameters and spawning stock size. ... -
Flomvann fra Glomma og miljøforholdene i Skagerrak sommeren 1995. (The Glomma flood and the environmental conditions in the Skagerrak in the summer 1995)
Danielssen, Didrik S.; Skogen, Morten D.; Aure, Jan; Svendsen, Einar (Fisken og havet, Research report, 1996)The fresh-water influence from the flood in June, 1995 to the eastern Skagerrak created an unusual and very fresh surface layer with a strong halocline. The surface water with extremely low salinities was detected all ... -
