Amplitude and phase of principal tidal constituents were computed by using the tidal
analysis program T_TIDE (Pawlowicz and others 2002). The
principal
constituents are K1, O1, M2, N2,
and S2. This report includes the full output from T_TIDE for each data record.
The duration of time series used to compute the harmonics is different for each instrument, depending on instrument deployment and recovery times (see Appendix - Instrument Log), and data availability.
Table headings for T_TIDE output:
- tide: tidal constituent freq: frequency (cycles/hour)
-
major: major axis of tidal ellipse (for current observations) (centimeters per second [cm/s])
-
emaj: error estimate for major axis (cm/s)
-
minor: minor axis of tidal ellipse (cm/s)
-
emin: error estimate for minor axis (cm/s)
-
inc: inclination of major axis (counter clockwise from east) (degrees)
-
einc: error estimate for inclination (degrees)
-
phase: phase of major axis (degrees)
-
ephase: error estimate of phase (degrees)
-
snr: signal-to-noise ratio
Significant constituents (those with signal-to-noise ratio in the last column greater than 1) are indicated with an asterisk.
