#MarineScience - Researchers at NUI Galway, along with partners at the Irish Centre for Research in Applied Geosciences (iCRAG) and the Marine Institute, are currently carrying out a marine hydroacoustic survey in the eastern margin of the Porcupine Basin.

Continuing till this Saturday 16 June, the project conducted from the RV Celtic Voyager (Callsign EIQN) involves generating an acoustic sound source (seismic airgun) adjacent to a short-term deployment of a hydrophone mooring and drifter array in order to investigate noise propagation across the Irish continental margin. The project is planned to inform research into noise pollution as part of Ireland’s obligations under the Marine Strategy Framework Directive (MSFD).

Approximate locations of fixed moorings and seismic noise transect are included in Marine Notice No 24 of 2018, a PDF of which is available to read or download HERE.

Fixed moorings will include yellow surface buoys with warning lights: high intensity, quick flash, continuous, yellow. The drifter will include a yellow surface buoy with nav light: 5 flashes every 20 seconds, yellow, 2nm distance.

The RV Celtic Voyager is displaying appropriate lights and signals and will be within the vicinity at all times throughout the survey.

Researchers also emphasise that the closest distance from survey to any marine SAC is over 16 nautical miles. Commercial fishing and other marine operators are requested to keep a 3nm distance from any survey instrument moorings, and to keep a 2nm distance around the entire survey area clear of any gear or apparatus during the survey period outlined above.

Whether you're a boat enthusiast, historian, archaeologist, fisherman, or just taken by the natural beauty of Ireland's waterways, you will find something of interest in our Inland pages on Afloat.ie.

Inland Waterways

Ireland is lucky to have a wealth of river systems and canals crossing the country that, while once vital for transporting goods, are today equally as important for angling, recreational boating and of course tourism.

From the Barrow Navigation to the Erne System, the Grand Canal, the Lower Bann, the Royal Canal, the Shannon-Erne Waterway and the Shannon Navigation, these inland waterways are popular year in, year out for anyone with an interest in rambling; flora and fauna; fishing; sailing; motorboating; canoeing, kayaking and waterskiing; and cruising on narrowboats.

Although most will surely identify Ireland's inland waterways with boating holidays and a peaceful afternoon's angling, many varieties of watersport are increasingly favoured activities. Powerboat and Jetski courses abound, as do opportunities for waterskiing or wakeboarding. For those who don't require engine power, there's canoeing and kayaking, as Ireland's waterways have much to offer both recreational paddlers and those looking for more of a challenge. And when it comes to more sedate activities, there's nothing like going for a walk along a canal or river bank following some of the long-distance Waymarked Ways or Slí na Sláinte paths that criss-cross the country.

Ireland's network of rivers, lakes and canals is maintained by Waterways Ireland, which is one of the six North/South Implementation Bodies established under the British-Irish Agreement in 1999. The body has responsibility for the management, maintenance, development and restoration of inland navigable waterways on the island of Ireland, principally for recreational purposes. It also maintains Ireland's loughs, lakes and channels which are sought after for sailing; the network of canal locks and tow paths; as well as any buoys, bridges and harbours along the routes.

Along the Grand and Royal Canals and sections of the Barrow Navigation and the Shannon-Erne Waterway, Waterways Ireland is also responsible for angling activities, and charges Inland Fisheries Ireland with carrying out fisheries development, weed management and ensuring water quality.

Brian Goggin's Inland Blog

Giving his personal perspective on Ireland's Inland Waterways from present-day activities to their rich heritage, Brian Goggin tells it like it is with his Inland Blog.

From recognising achievements in management of the waterways to his worries on the costs of getting afloat on Ireland's canals, Goggin always has something important to say.

He also maintains the website Irish Waterways History that serves as a repository for a wealth of historical accounts of the past commercial and social uses alike of Ireland's rivers and canals, which were once the lifeblood of many a rural community.
