Dear colleagues,

A new internet connection has been installed at Dunkerque tide observatory by our colleagues from the French national hydrographic service (SHOM - Séverine Enet) together with our colleagues from French IGN (Thomas Donal).
The GNSS permanent station DUNQ located at the tide gauge and part of EUREF is now repaired.
Best regards,
