Miljøundersøkelser i norske fjorder 1975 - 1993 2. Finnmark: Tanafjord, Laksefjord, Porsangerfjord og Altafjord

Abstract

The Institute of Marine Research have monitored the environmental conditions in about 27 Norwegian fjord regions since 1975. This report describe the temperature, salinity, oxygen and inorganic nuirient conditions during late autumn in Tanafjord, Laksefjord, Porsangerfjord and Altafjord in Finnmark. The observations indicate no long term changes in oxygen nor in nutrient consentrations in the deep water during the period 1981-1993. From 1983 there has been a significant temperature increase which culrninated mund 1990191. After 1992 the w m period seems to be coming to an end with significant lower temperatures. The next report will be from the Troms region in northem Norway.NORSK SAMMENDRAG:Havforskningsinstituttet har overvåket miljøforholdene i omlag 27 nordregioner langs kysten. Denne rapporten beskriver temperatur, saltholdighet, oksygen og næringssaltforholdene i novemberldesember i Tanafjord, Laksefjord, Porsangerfj ord og Altafjord i Finnmark.
