STRAMIX tidal harmonic components from horizontal currents of a RDI 600-kHz work horse Acoustic Doppler Current Profiler (ADCP) (v.1)

Tidal harmonic analysis of ADCP currents from june 2013 to August 2014 in the Ría de Vigo (NW Iberia, Atlantic Ocean), STRAMIX project. Horizontal velocities were screened for errors greater than 20cm/s following Gilcoto et al., 2009. Afterwards, each of the 55 current-velocity vertical levels (75 cm bin size) were averaged every 5 minutes. Finally, the MATLAB tidal analysis package t-tide (Pawlowicz et al., 2002) was applied, level by level, to the vectorial combined horizontal velocity components. A database of ellipse parameters for the 55 levels and 53 tidal constituents (selected with a Rayleigh criteria of 1) was obtained. The length of the time series allowed us for the first time to separate S1 and K1
