On the variability of Atlantic Influence in the Norwegian and Barents Seas
Variability in Atlantic influence in the regime of the Norwegian Atlantic current and its branches in the Barents Sea are studied by establishing time series of mean temperature and salinity values in four hydrographic sections. A section Svinøy-NW was worked in December from 1951 to 1968 and in Jan...

Variability in Atlantic influence in the regime of the Norwegian Atlantic current and its branches in the Barents Sea are studied by establishing time series of mean temperature and salinity values in four hydrographic sections. A section Svinøy-NW was worked in December from 1951 to 1968 and in January from 1952 to 1973. In the Barents Sea three sections have been worked in August-October, one between Fugløya and Bjørnøya since 1964, one northward from Vardø along 31°13'E since 1953 and one northward from the Sem Islands along 37°20'E since 1956. Mean values of temperature and salinity have been established for parts of the sections in the depth intervals 0-50, 50-100 and 100-200 m. Three-year running means have been prepared to reduce the effect of year-to-year fluctuations.
