Using a common method to process measured data a significant description of the Spanish sea environment will be achieved. KEY WORDS: ESEOO; data analysis; currents; salinity; waves...

... We use the Hilbert-Huang Transform (HHT) for the spectral analysis of waves during a storm in the North Sea that took place in 1999. We look at the contribution of the different Intrinsic Mode Functions (IMF) obtained by the Empirical Mode Decomposition algorithm and also compare the Hilbert...

One advantage of this approach is that the classical spectral analysis can be used in each stationarity interval with the usual interpretation of the spectrum as the distribution of energy in a range of frequencies. To implement this approach...

.... A time domain analysis is carried out by using time dependent hydrodynamic damping which arises from the fluid-structure interaction. A traditional linearized spectral analysis is also carried out and the results are compared with those obtained from the time domain analysis. Since the hydrodynamic...
