tidalCurrent {oce} | R Documentation

## Tidal Current Dataset

### Description

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.
