The buoy, which is located in the Celtic Sea some 50 km off the Wexford coast, was successfully redeployed by the Marine Institute’s vessel RV Celtic Explorer on the 30th May after being offline since early February.
It is now transmitting a wide range of information on wind speed and direction, atmospheric pressure, wave height, sea and air temperature, all of which can be accessed online via the Marine Institute’s website at www.marine.ie/databuoy.
In addition to the floating weather buoy network, which is exposed to waves and wind, the Marine Institute with a range of other bodies is planning the deploymentof an array of submerged sensors and instrumented buoys in Galway Bay as part of the SmartBay system.
Phase 1 of this network, which will consist of a number of instrumented buoys located at sites critical for climate change, aquaculture and wave energy research will be deployed shortly on the west coast of Ireland. These buoys will provide a wide range of oceanographic and environmental information leading to an even greater understanding of our seas and oceans.
"Keeping the weather buoy network fully functional in as harsh an environment as the Celtic Sea can be extremely challenging,” said Dr Peter Heffernan, CEO of the Marine Institute.
“After the M5 weather buoy stopped transmitting on the 3rd February it was recovered a week later and replaced by a second buoy, which in turn failed after only two weeks. Bad weather and complex engineering issues has constantly hampered any attempt to recover and replace the second buoy using our smaller vessel RV Celtic Voyager, but her larger sister ship RV Celtic Explorer finally managed the job on the 30th May."
"I would like to pay tribute to our partners in the Department of Transport, Met Eireann and the UK Met Office in creating the network, which continues to provide information vital not only to maritime safety and survival but also to our understanding of the oceans and climate change.”
