Modernisation of the tide gauge at Port-Tudy (Ile de Groix)
The tide gauge at Port-Tudy on the Ile de Groix was modernised by SHOM between 15 and 21 March 2011. This operation was performed in partnership with the Morbihan Department Council and the Ile de Groix town council. A telemetry radar has now replaced the old float tide gauge.
