A large fraction of the variance in many oceanographic variables is due to tides.   As a result, for many practical applications in the marine environment accurate maps of tidal currents or elevations are often indispensable. Knowledge of tides is of value in many scientific studies as well.

Our global and local models of barotropic tide provide elevations (relative to mean sea level) and transports/currents. They are available for free download - use menu on left to navigate the page.

Check out our new TPXO Web Service to get tide predictions at any location.
