#MarineNotice - The latest Marine Notice from the Department of Transport, Tourism and Sport (DTTAS) advises that marine scientists from the Dublin Institute of Advanced Studies (DIAS) are deploying a tsunameter close to the new location of the M4 weather buoy off the Donegal coast.

In addition to the tsunameter, they will also deploy a sub-surface buoy with an acoustic Doppler current profiler (ADCP) mounted on it, as well as pressure sensors clamped to a moored string to measure pressure variations at depth. This system will be deployed in proximity to the tsunameter location but not too close to avoid tangling.

The tsunameter and system used for the ADCP and the pressure string sensors is scheduled to be be deployed imminently from the RV Celtic Voyager (Callsign: EIQN) at latitude 54°59.892 N, longitude 009°58.14 W, at a depth of 119m adjacent to M4 weather buoy.

As this is sensitive scientific equipment, it is requested that fisherman and marine operators engaged in such activities as bottom trawling or laying of static gear avoid the locations concerned to avoid damaging the equipment or damaging fishing gear.
