INFOMAR, a joint venture by the Geological Survey Ireland and the Marine Institute, has launched a collection of 18 high-resolution bathymetric maps of Ireland’s coastal waters. The Blue Scale Map Series is the culmination of over a decade of work and highlights the unique and intricate landscapes lying beneath the waves. 

Each week, INFOMAR will release a new map of a different section of the Irish coastline. The latest in the series is the blue scale bathymetric map of Loop Head, County Clare on the Shannon Estuary. 

The area was first surveyed in 2009 on board the RV Celtic Voyager, with the INFOMAR team mapping a total of 162km2 of seabed along the River Shannon and west of Loop Head. Mapping continued in the region on board the RV Celtic Voyager, RV Keary, RV Geo & MV Cosantóir Bradán between 2011 – 2014, resulting in an area of over 2000km2 of previously unmapped Clare coastal waters being surveyed in high resolution.

Earlier this year, INFOMAR’s inshore team, on board the RV Galtee, continued mapping shallower waters beneath the Iconic Cliffs of Moher, Liscannor Bay and Kilstiffin Reef.

The Blue Scale Map Series offers a new and unique way not only to showcase the mapping effort to date but also to visualize and communicate complex scientific information to the wider public. As with all INFOMAR data, these high-resolution maps are available for free to download and have huge potential to communicate with local coastal communities and raise awareness of the importance of maintaining the health and integrity of our marine environment.

Ireland’s coastline is approximately 3,171km in length and boasts some of the most unique and dynamic marine environments in Europe. Since 2006, INFOMAR’s seabed mapping efforts have been instrumental in enhancing our understanding of Ireland's underwater landscape. The Blue Scale Map Series not only highlights the topography of the coast in remarkable detail but also paves the way for the future management of Ireland’s marine resource.

An underwater survey of Dublin Bay is expected to commence this Friday, (1st October 2010). It is part of a Dublin City Council (DCC) project to upgrade the Ringsend Wastewater Treatment Plant. Preliminary works will include a Bathymetric Survey of Dublin Bay and its approaches and last for a period of approximately one month. The area to be surveyed is attached in a Notice to Mariners issued by Dublin Port Company. The survey will be carried out by a 12 metre yellow hull catamaran "Xplorer". The "Xplorer" is fitted with A.I.S.

Galway Port & Harbour

Galway Bay is a large bay on the west coast of Ireland, between County Galway in the province of Connacht to the north and the Burren in County Clare in the province of Munster to the south. Galway city and port is located on the northeast side of the bay. The bay is about 50 kilometres (31 miles) long and from 10 kilometres (6.2 miles) to 30 kilometres (19 miles) in breadth.

The Aran Islands are to the west across the entrance and there are numerous small islands within the bay.

Galway Port FAQs

Galway was founded in the 13th century by the de Burgo family, and became an important seaport with sailing ships bearing wine imports and exports of fish, hides and wool.

Not as old as previously thought. Galway bay was once a series of lagoons, known as Loch Lurgan, plied by people in log canoes. Ancient tree stumps exposed by storms in 2010 have been dated back about 7,500 years.

It is about 660,000 tonnes as it is a tidal port.

The dock gates open approximately two hours before high water and close at high water subject to ship movements on each tide.

The typical ship sizes are in the region of 4,000 to 6,000 tonnes

Turbines for about 14 wind projects have been imported in recent years, but the tonnage of these cargoes is light. A European industry report calculates that each turbine generates €10 million in locally generated revenue during construction and logistics/transport.

Yes, Iceland has selected Galway as European landing location for international telecommunications cables. Farice, a company wholly owned by the Icelandic Government, currently owns and operates two submarine cables linking Iceland to Northern Europe.

It is "very much a live project", Harbourmaster Capt Sheridan says, and the Port of Galway board is "awaiting the outcome of a Bord Pleanála determination", he says.

90% of the scrap steel is exported to Spain with the balance being shipped to Portugal. Since the pandemic, scrap steel is shipped to the Liverpool where it is either transhipped to larger ships bound for China.

It might look like silage, but in fact, its bales domestic and municipal waste, exported to Denmark where the waste is incinerated, and the heat is used in district heating of homes and schools. It is called RDF or Refuse Derived Fuel and has been exported out of Galway since 2013.

The new ferry is arriving at Galway Bay onboard the cargo ship SVENJA. The vessel is currently on passage to Belem, Brazil before making her way across the Atlantic to Galway.

Two Volvo round world races have selected Galway for the prestigious yacht race route. Some 10,000 people welcomed the boats in during its first stopover in 2009, when a festival was marked by stunning weather. It was also selected for the race finish in 2012. The Volvo has changed its name and is now known as the "Ocean Race". Capt Sheridan says that once port expansion and the re-urbanisation of the docklands is complete, the port will welcome the "ocean race, Clipper race, Tall Ships race, Small Ships Regatta and maybe the America's Cup right into the city centre...".

The pandemic was the reason why Seafest did not go ahead in Cork in 2020. Galway will welcome Seafest back after it calls to Waterford and Limerick, thus having been to all the Port cities.
