Abstract
Oscillation modes in mean sea level in the port of Cadiz are computed and analyzed from simultaneous water level and atmospheric pressure re cords. Empirical Orthogonal Function Decomposition (EOF), cross spectr al and least square harmonic analysis are used. EOF is applied in an u nusual way in order to extract common oscillation modes of atmospheric pressure and Mean Sea Level (MSL) series. In spite of the short lengt h of time series, less than four months, EOF is a very powerful tool a nd makes possible the isolation of astronomical and meteorological osc illation modes.
