The Tidal stream atlas netcdf product – Western Brittany provides tidal current data for an area stretching from the northern coast of Brittany (Porsguen) to the south of Penmarc'h. The product consists of four gridded files with different spatial resolutions covering the Finistère area (overall view at 500 m) and the geographical areas of the Iroise Sea (250 m), Brest bay (100 m) and Brest harbour (30 m). The U and V velocities of the tidal currents depend on the tidal conditions considered at mean neap and spring tidal rates. The data are provided in m/s for the surface layer. The times are given in relation to high tide at the reference port chosen in the area and are provided from 6 hours before to 6 hours after that reference.

The Tidal stream atlas netcdf product – Seine Bay provides tidal current data for an area stretching from Fecamp at the east of the area to Cherbourg at the west. The product consists of two gridded files with different spatial resolutions covering the Seine Bay area (overall view at 500 m) and the geographical area of Le Havre harbour (250 m). The U and V velocities of the tidal currents depend on the tidal conditions considered at mean neap and spring tidal rates. The data are provided in m/s for the surface layer. The times are given in relation to high tide or low tide at the reference port chosen in the area and are provided from 6 hours before to 6 hours after that reference.

The Tidal stream atlas netcdf product – The Bay of Biscay provides tidal current data for an area stretching from Brittany to the northern coast of Spain. The product consists of a unique gridded file with 2 km spatial resolution covering the Bay of Biscay. The U and V velocities of the tidal currents depend on the tidal conditions considered at mean neap and spring tidal rates. The data are provided in m/s for the surface layer. The times are given in relation to high tide at the reference port chosen in the area and are provided from 6 hours before to 6 hours after that reference.

Litto3D is a unique and continuous land-sea database which can provide 3D models of the shape and location of French coastal terrain. Litto3D digital models are available in two formats: a set of 3D points and a qualified terrain mesh.

This service allows users to view surface tidal current predictions calculated from the analysis of a high-resolution hydrodynamic simulation projected onto a 30 m grid. This service was built by Shom and funded by French CCI Métropolitaine Bretagne Ouest in the frame of the Atlantic Blue Port project of <a href="https://www.atlanticarea.eu" target="_blank">Interreg Atlantic Area</a> european program.

The Tidal stream atlas netcdf product – Northern Brittany provides tidal current data for an area stretching from Tregastel at the east of the area to Porsguen at the west. The product consists of two gridded files with different spatial resolutions covering the Northern Brittany area (overall view at 500 m) and the geographical area of the port of Roscoff (250 m). The U and V velocities of the tidal currents depend on the tidal conditions considered at mean neap and spring tidal rates. The data are provided in m/s for the surface layer. The times are given in relation to high tide at the reference port chosen in the area and are provided from 6 hours before to 6 hours after that reference.
