The M6 Weather Buoy as part of the Irish Marine Data Buoy Network is designed to improve weather forecasts and safety at sea around Ireland. M6 is deployed west of Co. Galway off the west coast of Ireland beyond the continental shelf in deep waters approximately 250 nautical miles west of Slyne Head in the South Rockall Trough. The project is the result of successful collaboration between the Marine Institute, Met Eireann, the UK Met Office and the Irish Department of Transport, Tourism and Sport. This infrastructure has been part funded under the Marine RTDI Measure of the National Development Plan 2000-2006, co-funded by the European Regional Development Fund (ERDF). None
