Data were low-pass filtered using a Lanczos filter, and transformed to the frequency domain with the classical Fast Fourier Transform, rotary spectra, and the Morlet Wavelet Method. The strongest total currents developed in the eastern part of the bay, with a dominant east-west component. The predominant direction of the total current was parallel to the coast. The amplitude of tidal currents was small when compared with subtidal currents. During the sampling period several episodes of inertial currents were observed, some of which corresponded to those predicted by theory. Inertial currents in the lower layer were linked through large phase lags, revealing the baroclinic mode of the inertial currents. Spectral energy was concentrated in the low-frequency bands, corresponding to inertial and subinertial periods. The dominance of spectral energy at low frequencies reveals the influence of mesoscale cyclonic and small-scale anticyclonic eddies in the northeastern Bay of Campeche. These eddies are believed to be the origin of the inertial currents, since the inertial currents observed were unrelated to wind forcing. 2009 artículo científico 0185-3880 https://www.redalyc.org/articulo.oa?id=48013181004 en http://www.redalyc.org/revista.oa?id=480 Ciencias Marinas application/pdf Universidad Autónoma de Baja California Ciencias Marinas (México) Num.3 Vol.35 |
