Surface tidal currents on Iroise sea

This service allows users to view surface tidal current predictions calculated from the analysis of a high-resolution hydrodynamic simulation projected onto a 250 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.

Statement

Surface tidal current predictions computed from statistical values obtained from hydrodynamic model gridded with a regular 250 m spatial resolution.

Those statistics are then interpolated/extrapolated every 15 minutes (cubic spline), and for each tide coefficient from 20 to 120 (linear). The statistical currents, initially referenced to Brest high tide, are then referenced to the hour requested by the user using the tide prediction service https://maree.shom.fr .
