Proudman tidal module

The Proudman Tidal Module has been developed by the well known Proudman Oceanographic Laboratory based in the United Kingdom. The module shows the direction and rate of horizontal tidal movement for every 12 kilometres on the Continental Shelf and 30 kilometres outside the Continental Shelf. The predictions are based on about 40 years of observations. The Proudman tidal databases can only be used with the Proudman modules of Chartworx Electronic Chart Systems. Updates are not necessary. The data can be used for an unlimited period of time. The attention is drawn to the fact that the constituents used for the predictions are  astronomical constituents so no corrections for meteorological influences or shallow water effects have been applied.

The Proudman tidal databases supplied by Chartworx cover the same area as the Chartworx C-MAP databases.

Proudman tidal databases are an option and have to be ordered separately.
