Installation of a new tide gauge observatory on the Ile d'Aix

From 18 to 22 March 2011, technicians from the Universityof La Rochelle and SHOM went to the Ile d'Aix (Charente-Maritime) in order to install an Optiwave telemetry radar on the Barbotin jetty. The installation was performed in partnership with the Charente-Maritime Department Council (CG17), responsible for the jetty and equipment room in the fort housing the instrumentation.

For this work and its operation, the laboratory for Coastal Environment and Companies (LIENSs) of the University of La Rochelle and SHOM joined together in considering the need for the University of La Rochelle to install a tide gauge on the Ile d'Aix and to incorporate it into the network for sea level observations (RONIM) on the one hand, and the common interest of the University of La Rochelle and SHOM to have reliable data on the height of sea levels in the Antioche straits on the other.

The new measurements will also make it possible to augment the observations made during the 19th century on the Ile d'Aix, FortEnetand FortBoyard, sites which are separated from each other by less than 2 nautical miles. For further information, consult the following page.

This tide gauge installation is supplemented with a permanent GPS, installed in partnership between IGN and the Universityof La Rochelle and situated 300m from the jetty, in the harbour fort.

Data on heights of water at the Ile d'Aix will soon be available in non-real-time in REFMAR. Furthermore, the tide gauge will soon be transmitting these data in real time.
