Internal Tides West of the Iberian Peninsula
We analyze archived historical moored measurements around the Iberian Peninsula to estimate the amplitudes of the semidiurnal internal tides on a basin-scale. Decay of amplitudes as the internal tide propagates from the continental slope is estimated. Directions and wavelengths of the internal tides are determined from the spatiotemporal spectra at the semidiurnal frequency calculated from the data of moored temperature measurements on clusters of moorings in the middle of the Iberian Basin and south of the Iberian Peninsula.
