Coastal Change Processes Project Data Report for Observations Near Fire Island, New York, January to April 2012
Amplitude and phase of principal tidal constituents were computed by using the tidal
analysis program T_TIDE (Pawlowicz and others 2002). The
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.
