Abstract
The water level records of 11 stations from the Norwegian coast having the recording interval 1971–1972 in common have been analysed with a least squares algorithm. The results for the harmonic constants are compared to open ocean tide models and a good agreement is found. The variation of tidal parameters and mean sea level are calculated from a 70 years water level record from Bergen. An 18.6 yearly variation in amplitude and phase of the fortnightly tide Mf could be identified.
Cross correlation techniques are used to investigate the nontidal part of the water level changes. Correlating the residuals of the analyses with each other, the main nontidal water level changes are found to be moving from south to north along the Norwegian coast, taking 20 hours to reach from Stavanger to Vadsø. The effect of local air pressure on sea level is modelled using transfer functions.
Mean sea level changes in Bergen are found to correlate with changes in length of day and changes in global surface temperature.
