We consider the evolution of spectra of random waves over periods of three days. Two segmentation methods are used: Detection of Changes by Penalized Contrasts (DCPC) proposed and developed by Lavielle (1998, 1999) and Smooth Localized complex Exponentials (SLEX) proposed in Ombao et al. (2001). We compare the results obtained with both methods. In each case the intervals obtained are considered stationary and the corresponding spectra are obtained. For both sets of intervals the classical Fourier spectrum is obtained using the WAFO software. We compare some of the spectra obtained. We also apply both methods to the Hurricane Camille wave height data. Copyright © 2006 by The International Society of Offshore and Polar Engineers.
