#MarineScience - The Marine Institute’s RV Celtic Voyager returned to Cork Harbour last week after the first of six INFOMAR seabed mapping surveys planned for 2017.

The two-week seabed survey carried out its operations in the Celtic Sea south of the Waterford and Wexford coastlines.

The research team — involving geophysicists, geologists, marine biologists and data processors Kevin Sheehan, David O'Sullivan, Oisin McManus, Nicola O'Brien and Michael Arrigan — were tasked to accurately map the physical, chemical and biological features of the seabed area.

INFOMAR survey operations are conducted by a fleet of research vessels — including the RV Celtic Voyager, which is used for mapping seabed terrain in water depths between 20m and 100m.

The vessels are equipped with advanced mapping technologies including state-of-the-art acoustic sonars, geophysical instrumentation and ground-truthing capabilities, as well as geophysical equipment and precise satellite positioning.

“This helps to ensure data collection is of the highest possible quality across a wide range of water depths, conditions and environments, providing us with full coverage mapping of the shape and type of the seabed below,” says David O'Sullivan.

The INFOMAR survey around Ireland is one of the largest civilian seabed mapping projects in the world and aims to gather high resolution seabed data that contributes to the sustainable development of Ireland's marine resource.

As an island nation, Ireland is responsible for the sustainable management of its marine resources and it is important that accurate seabed maps are created to enable effective governance.

“Gathering up-to-date information about our ocean is cognisant of ensuring we have the best available science and knowledge to inform decisions affecting our ocean, particularly in relation to fisheries management and the development of ocean energy,” added O’Sullivan.

The INtegrated Mapping FOr the Sustainable Development of Ireland's MArine Resource (INFOMAR) programme is a joint venture between the Geological Survey of Ireland and the Marine Institute, funded by the Department of Communications, Climate Action and Environment.

#SeabedMapping - The Atlantic Ocean Research Alliance's fifth transatlantic seabed mapping survey launched last Friday 22 July from eastern Canada.

Sailing on the Canadian Coast Guard Ship Louis S St-Laurent, the team will map the seafloor across the North Atlantic between Halifax in Nova Scotia and Tromso in Norway till next Tuesday 2 August.

The marine science team led by Paola Travaglini of Fisheries and Oceans Canada's Hydrographic Service are using state-of-the-art deep-water multibeam sonar technology to survey the seabed and study the physical characteristics of the seafloor, as well as other oceanographic data such as temperature and salinity, to better understand little-known areas of the North Atlantic and build on the work done last summer.

These surveys support the Galway Statement on Atlantic Ocean Co-operation, the goals of which are to join resources of its three signatories to better understand the North Atlantic, to promote sustainable management of its resources, and to promote citizens' understanding of the Atlantic through ocean literacy.

Participants in the survey include Fisheries and Oceans Canada's Hydrographic Service, the University of New Hampshire's Center for Coastal and Ocean Mapping Joint Hydrographic Center, and the Fisheries and Marine Institute of Memorial University of Newfoundland.

Students and early-career scientists representing Canada and the United States sailing on board the CCGS Louis S St-Laurent are writing daily blog posts to chronicle the mission. The team comprises:

  • David Thornhill, Hydrographer, Fisheries and Oceans Canada Canadian Hydrographer Service
  • Danielle Roche, Marine Institute of Memorial University of Newfoundland
  • Darren Hiltz, Hydrographer, Fisheries and Oceans Canada Canadian Hydrographer Service
  • Elizabeth Weindren, University of New Hampshire's Center for Coastal and Ocean Mapping Joint Hydrographic Center Fisheries
  • Chris Hemmingway, National Director of UNCLOS, Fisheries and Oceans Canada Canadian Hydrographer Service
  • David Levy, Electrical Technician, Fisheries and Oceans Canada Canadian Hydrographer Service
  • Paola Travaglini, Hydrographer–In–Charge, Fisheries and Oceans Canada Canadian Hydrographer Service

Seabed mapping was one of the ocean research priorities and challenged discussed by the Marine Institute's CEO Dr Peter Heffernan with other heads of European marine science institutes in Ostend earlier this month, which followed a previous consultation that identified such mapping as crucial for managing human activities in our seas.

#MarineScience - Marine Institute chief executive Dr Peter Heffernan was among the heads of European marine science institutes meeting with Karmenu Vella, EU Commissioner for Environment, Maritime Affairs and Fisheries, at the European Marine Board offices in Ostend, Belgium yesterday (Friday 8 July) to discuss ocean research priorities and challenges.

The meeting with Commissioner Vella follows a previous consultation attended by Dr Heffernan in March, which identified ocean observation and seabed mapping as crucial for managing human activities in European seas and across the global ocean.

The European Marine Board said the latest meeting will advance the discussion on ocean observing and seabed mapping in Europe, set within a global context, by identifying critical gaps in our capability, investment needs and potential funding sources for the future.

“Ocean observation and seabed mapping are essential for managing human activities in the ocean," said Dr Heffernan. "With better observation and prediction capability, we can de-risk investment; we can have well informed licensing and regulation for sustainable economic developments; and we can protect ocean ecosystems and the essential services they provide, like food, medicine, and providing half of the oxygen we breathe.”

The Marine Institute CEO added: “Ireland has much to contribute to these consultations as we have significant seabed mapping expertise through INFOMAR, the national seabed mapping programme led by the Geological Survey of Ireland and the Marine Institute.

"And we are developing key ocean observation and marine research infrastructure in Ireland to advance our understanding of the ocean and to underpin innovation in the ocean."

Mapping, observing and predicting changes in the ocean were the focus of discussion at the Our Ocean Wealth conference in Galway last week, at which Ireland’s first ocean observatory was officially launched.

The meeting with Commissioner Vella in Ostend marks the second in a series and is an important platform for the ocean research community to communicate directly with the commissioner on ocean research issues.

#MarineScience - Three Transition Year students recently completed placements hosted by INFOMAR at the Marine Institute.

Jack Lillis, Aoife Muldoon and Emily Egan learned how seabed mapping can improve safety at sea, how it relates to the fishing industry, and how it can help the development of sectors like ocean energy.

Each student spent a week visiting the various Marine Institute facilities and learning about the different activities of the institute.

At the end of their experience, each created a 'story map' and PowerPoint presentation to show what they achieved during their placements.

"We really enjoyed our week at the Marine Institute and we now know a lot more about what a career in marine science really means," said Muldoon and Egan, from St Brigid's Vocational School in Loughrea. "It's a hugely interesting area of science that we don't learn about in school.

"We especially enjoyed our visit to the Celtic Explorer, seeing the multibeam system, learning about seabed mapping and how this information improves the admiralty charts so that vessels like the Celtic Explorer can safely visit ports. We also learnt about how seabed mapping relates to the fishing industry and helps sectors like ccean energy, this was of particular interest to us.

"We would like to thank Vera and all the Advanced Mapping Services and Marine Institute staff for teaching us so much about seabed mapping, fisheries, the laboratories and how all the different areas interlink. We now have a much better idea of what subjects to pick for the Leaving Cert."

Lillis, of Gort Community School, also had "a fantastic week, all the areas I worked in were really enjoyable. I was particularly interested with the laboratory work. Everybody knew what they were talking about and nobody shied away from any questions in fact they encouraged them. Everybody had something lined up for me to do so I was kept really busy, which was great.

"Overall I really enjoyed my week in the Marine Institute and I'm a glad I chose it for my first week of work experience. It was both a good way to see a working environment but also has encouraged me to pursue a career in marine related chemistry. Thanks so much to Tommy, Vera, the Advanced Mapping Services team and staff at the Marine Institute for taking time out of their busy day to facilitate me."


The Marine Institute will run its Transition Year course placements on a pilot basis at the end of April for up to 20 students.

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.
