The ship which sent an iceberg warning to the RMS Titanic, before the ocean liner sank, has been identified lying in the Irish Sea by researchers from Bangor University in Wales.

In 1912 the merchant steamship SS Mesaba was crossing the Atlantic and sent a warning radio message to the RMS Titanic. The message was received, but never reached the bridge.

Later that night, the supposedly unsinkable Titanic hit an iceberg and sank on her maiden voyage, taking 1,500 lives and becoming the world’s most infamous shipwreck. 

The SS Mesaba continued as a merchant ship over the next six years before being torpedoed while in convoy in 1918.

Using state-of-the art multibeam sonar mounted on Bangor University’s research vessel Prince Madog, researchers have finally been able to positively identify the wreck and have revealed her position for the first time.

“For the marine archaeologist, multibeam sonar has the potential to be as impactful as the use of aerial photography was for landscape archaeology,” the university says.

Multibeam sonar enables seabed mapping of such detail that superstructure details can be revealed on the sonar images, it adds.



The SS Mesaba was one among 273 shipwrecks lying in 7,500 square miles of Irish Sea which were scanned and cross-referenced against the UK Hydrographic Office’s database of wrecks and other sources.


It was thought that 101 wrecks were unidentified, but the number of newly identified wrecks was far higher, as many — the SS Mesaba included — had been wrongly identified in the past.



Details of all the wrecks have been published in a new book, Echoes from the Deep by Dr Innes McCartney of Bangor University, conducted under a Leverhulme Fellowship while at Bournemouth University.

Dr McCartney said: “The results of the work described in the book has validated the multidisciplinary technique employed and it is a ‘game-changer’ for marine archaeology.

“Previously we would be able to dive to a few sites a year to visually identify wrecks. The Prince Madog’s unique sonar capabilities has enabled us to develop a relatively low-cost means of examining the wrecks. We can connect this back to the historical information without costly physical interaction with each site.


“It should be of key interest to marine scientists, environmental agencies, hydrographers, heritage managers, maritime archaeologists and historians.” 



Dr Michael Roberts, who led the sonar surveys at the university’s School of Ocean Sciences, said: “The expertise and unique resources we have at Bangor University, such as the Prince Madog enable us to deliver high-quality scientific research in an extremely cost-effective manner.

“Identifying shipwrecks such as those documented in the publication for historical research and environmental impact studies is just one example of this.

“We have also been examining these wreck sites to better understand how objects on the seabed interact with physical and biological processes, which in turn can help scientists support the development and growth of the marine energy sector.”

Dublin Bay

Dublin Bay on the east coast of Ireland stretches over seven kilometres, from Howth Head on its northern tip to Dalkey Island in the south. It's a place most Dubliners simply take for granted, and one of the capital's least visited places. But there's more going on out there than you'd imagine.

The biggest boating centre is at Dun Laoghaire Harbour on the Bay's south shore that is home to over 1,500 pleasure craft, four waterfront yacht clubs and Ireland's largest marina.

The bay is rather shallow with many sandbanks and rocky outcrops, and was notorious in the past for shipwrecks, especially when the wind was from the east. Until modern times, many ships and their passengers were lost along the treacherous coastline from Howth to Dun Laoghaire, less than a kilometre from shore.

The Bay is a C-shaped inlet of the Irish Sea and is about 10 kilometres wide along its north-south base, and 7 km in length to its apex at the centre of the city of Dublin; stretching from Howth Head in the north to Dalkey Point in the south. North Bull Island is situated in the northwest part of the bay, where one of two major inshore sandbanks lie, and features a 5 km long sandy beach, Dollymount Strand, fronting an internationally recognised wildfowl reserve. Many of the rivers of Dublin reach the Irish Sea at Dublin Bay: the River Liffey, with the River Dodder flow received less than 1 km inland, River Tolka, and various smaller rivers and streams.

Dublin Bay FAQs

There are approximately ten beaches and bathing spots around Dublin Bay: Dollymount Strand; Forty Foot Bathing Place; Half Moon bathing spot; Merrion Strand; Bull Wall; Sandycove Beach; Sandymount Strand; Seapoint; Shelley Banks; Sutton, Burrow Beach

There are slipways on the north side of Dublin Bay at Clontarf, Sutton and on the southside at Dun Laoghaire Harbour, and in Dalkey at Coliemore and Bulloch Harbours.

Dublin Bay is administered by a number of Government Departments, three local authorities and several statutory agencies. Dublin Port Company is in charge of navigation on the Bay.

Dublin Bay is approximately 70 sq kilometres or 7,000 hectares. The Bay is about 10 kilometres wide along its north-south base, and seven km in length east-west to its peak at the centre of the city of Dublin; stretching from Howth Head in the north to Dalkey Point in the south.

Dun Laoghaire Harbour on the southside of the Bay has an East and West Pier, each one kilometre long; this is one of the largest human-made harbours in the world. There also piers or walls at the entrance to the River Liffey at Dublin city known as the Great North and South Walls. Other harbours on the Bay include Bulloch Harbour and Coliemore Harbours both at Dalkey.

There are two marinas on Dublin Bay. Ireland's largest marina with over 800 berths is on the southern shore at Dun Laoghaire Harbour. The other is at Poolbeg Yacht and Boat Club on the River Liffey close to Dublin City.

Car and passenger Ferries operate from Dublin Port to the UK, Isle of Man and France. A passenger ferry operates from Dun Laoghaire Harbour to Howth as well as providing tourist voyages around the bay.

Dublin Bay has two Islands. Bull Island at Clontarf and Dalkey Island on the southern shore of the Bay.

The River Liffey flows through Dublin city and into the Bay. Its tributaries include the River Dodder, the River Poddle and the River Camac.

Dollymount, Burrow and Seapoint beaches

Approximately 1,500 boats from small dinghies to motorboats to ocean-going yachts. The vast majority, over 1,000, are moored at Dun Laoghaire Harbour which is Ireland's boating capital.

In 1981, UNESCO recognised the importance of Dublin Bay by designating North Bull Island as a Biosphere because of its rare and internationally important habitats and species of wildlife. To support sustainable development, UNESCO’s concept of a Biosphere has evolved to include not just areas of ecological value but also the areas around them and the communities that live and work within these areas. There have since been additional international and national designations, covering much of Dublin Bay, to ensure the protection of its water quality and biodiversity. To fulfil these broader management aims for the ecosystem, the Biosphere was expanded in 2015. The Biosphere now covers Dublin Bay, reflecting its significant environmental, economic, cultural and tourism importance, and extends to over 300km² to include the bay, the shore and nearby residential areas.

On the Southside at Dun Laoghaire, there is the National Yacht Club, Royal St. George Yacht Club, Royal Irish Yacht Club and Dun Laoghaire Motor Yacht Club as well as Dublin Bay Sailing Club. In the city centre, there is Poolbeg Yacht and Boat Club. On the Northside of Dublin, there is Clontarf Yacht and Boat Club and Sutton Dinghy Club. While not on Dublin Bay, Howth Yacht Club is the major north Dublin Sailing centre.
