Harmonic Constituents - NOAA Tides & Currents

Harmonic Constituents for 9710441, Settlement Point Bahamas

Constituent #: Order in which the National Ocean Service lists the constituents
Name: Common name used to refer to a particular constituent, subscript refers to the number of cycles per day
Amplitude: One-half the range of a tidal constituent
Phase: The phase lag of the observed tidal constituent relative to the theoretical equilibrium tide
Speed: The rate change in the phase of a constituent, expressed in degrees per hour. The speed is equal to 360 degrees divided by the constituent period expressed in hours
Description: The full name of the tidal constituent

Please refer to the Tide and Current Glossary for definitions of terms. Amplitudes are in feet. Phases are in degrees, referenced to Local. Z₀ (MSL): 0 feet
