This product includes Shom 3D digital data on tidal currents in the Channel in shapefile and geotiff formats. These digital files provide information on tidal current components (speed and direction) on an hourly basis (6 hours either side of high water for a reference port), and for two typical tidal coefficients (45 and 95). Cherbourg is taken as the reference port. Three layers are available: Surface; mid-depth; and sea-bed.

This product includes Shom 3D digital data on tidal currents in the Brest Bay - Iroise Sea in ASCII?,shapefile and geotiff formats. These digital files provide information on tidal current components (speed and direction) on an hourly basis (6 hours either side of high water for a reference port), and for two typical tidal coefficients (45 and 95). Brest is taken as the reference port. Three layers are available: Surface; mid-depth; and sea-bed.
