The tidalCurrent dataset contains tidal velocities reported in Foreman's (1978) report (reference 1) on his Fortran code for the analysis of tidal currents and provided in an associated webpage (reference 2). Here, tidalCurrent is data frame containing

  • time a POSIXct time.

  • u the eastward component of velocity in m/s.

  • v the northward component of velocity in m/s.

Source

The data come from the tide8.dat and tide9.dat files provided at reference 2.
