CBTide

Features:

- Harmonic analysis of tidal heights and tidal currents;
- Tidal heights and currents prediction.

The basis of the calculations on the methods set out in the publications of the Canadian Institute of Oceanography "Public Marine Science Report":

- “Manual for tidal heights analysis and prediction” by M.G.G. Foreman
Institute of ocean sciences, Patricia Bay, Sidney, B.C.
- “Manual for tidal currents analysis and prediction” by M.G.G. Foreman
Institute of ocean sciences, Patricia Bay, Sidney, B.C.

A lot of measurements of sea level and currents are available on the Internet. For example on the website NOAA http://tidesandcurrents.noaa.gov. According to this data, or data from other sources you can calculate harmonic constants for prediction of tides and tidal currents.
In addition, the Internet published harmonic constants for the various items. Some of them are converted to the CBTide format and can be downloaded from the support site http://www.chartbureau.com. However , it should be borne in mind that these data have not been verified by real sea levels .
