The Department of Transport has been advised of the deployment of a metocean data buoy by University College Dublin west of Inishmaan, some 6.6 nautical miles off Eeragh Lighthouse on Rock Island.

This deployment is scheduled to take place from Sunday 22 October for a period of up to seven days, subject to weather and operational constraints.

It will be carried out by the MV Chateau-Thierry (callsign EIHK6) which will display appropriate lights and signals.

Navigational warnings will be issued by radio when the marker buoy deployment takes place. A yellow special mark plastic buoy, IALA category 3 and 2.5m in diameter, will be used with a navigation light flashing white every 20 seconds at 4.1 meters above the surface.

Coordinates and a map of the deployment area, as well as contact details, can be found in Marine Notice No 65 of 2023, attached below.
