Amplitude and phase of tidal constituents were
computed using the tidal analysis program T_TIDE (Pawlowicz and
others, 2002). The principal
tidal constituents are K_{1}, O_{1}, M_{2}, N_{2}, and S_{2}. Due to gaps in
the data at Station B analysis was only performed for pressure data
from January 24, 2000 to April 16, 2000; this short data record
prevented analysis for all the tidal constituents.
This report includes summary tables for the principal constituents
and the full output from T_TIDE for each station. The T_TIDE output
includes the following columns:
 tide: tidal constituent
 freq: frequency (cycles/hour)
 major: major axis of tidal ellipse (for current observations)
(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 at time of major axis (degrees)
 ephase: error estimate of phase (degrees)
 snr: signal to noise ratio

Tidal Ellipses
The tidal current ellipse at each station is plotted in plan view for the ADCP observations obtained at 15 m. The size of the current ellipse is proportional to the current magnitude; the current scale for M_{2} has been chosen so that the length of the major axis is 5 times the distance a water particle would travel in onehalf tidal cycle at map scale (distance traveled = UT/π, where U is the major axis amplitude, and T is the tidal period). The current scale for the small N_{2}, S_{2}, K_{1}, and O_{1} tidal currents has been chosen so that the length of the major axis is 20 times the distance a water particle would travel in onehalf tidal cycle at map scale.
