“…These methods of data analysis were first introduced by meteorologists (STIDD, 1967;KUTZBACK, 1967) and have become a widely employed statistical procedure in oceanography. Different applications have dealt with sea level (AUBREY and EMERY, 1983;SOLOW, 1987;AUBREY et al, 1988), surface wind field (LEGLER, 1983;SERVAIN and LEGLER, 1986;KLINK and WILLMOTT, 1989), wind-wave spectra (VINCENT and RESIO, 1977), velocity fields (SULTAN and ELGHRIBI, 1998), sandbank evolution (REEVE et al, 2001), and beachprofile evolution (WINANT et al, 1975;AUBREY, 1979;AU-BREY et al, 1980;CLARKE and ELIOT, 1982;WIJNBERG and TERWINDT, 1995;RIHOUEY and MARON, 2003;LARSON et al, 2004).…”
