Ireland’s internationally important seabed mapping project has been profiled in The Irish Times as it enters the final years of its mission to fully chart the nation’s marine territory.

INFOMAR, a joint initiative of the Marine Institute and Geological Survey Ireland, is the latest iteration of a more than 20-year effort to map what’s one the largest seabed territories in Europe — an achievement that would also be a world first.

Making use of a range of research vessels, including the RV Celtic Explorer, INFOMAR regularly samples and collates data from the depths using a variety of techniques like multibeam sonar.

Experts use this data for models that are critical for the planning of offshore infrastructure such as undersea cables and wind farms — as well as the study of wildlife habitats and development in coastal communities.

And the project has even inspired a new Master’s degree course that aims to produce the next generation of marine mapping specialists.

The Irish Times has much more on the story HERE.

Marine scientists from Ireland will join an international group of ocean experts in a project to map and assess the Atlantic Ocean’s current and future risks from climate change, natural hazards and human activities.

Mission Atlantic brings the Marine Institute together with scientists from Europe, Brazil, South Africa, Canada and the USA to develop the first Integrated Ecosystem Assessments (IEAs) at the scale of the Atlantic basin.

Using high-resolution ocean models; data collected with marine robots and acoustic sensors; artificial neural networks; risk assessment methods; and advanced statistical analysis, the international partnership will assess the pressures imposed on the Atlantic’s marine ecosystems — especially those related to plankton and fish distribution — and identify the parts most at risk.

The Marine Institute says this “unique” project — funded by a €11.5 million grant from the European Union’s Horizon 2020 programme — will engage scientists, managers of marine resources and other stakeholders in balancing the need for environmental protection with sustainable development.

‘Mission Atlantic will contribute to a better and more sustainable future for life on Earth’

“In an era of rapid transformations affecting our societies and our lives, we are asked to provide the scientific knowledge necessary to face future challenges and to guarantee a sustainable future for the next generations,” says project co-ordinator Patrizio Mariani.

“By studying the complex Atlantic Ocean ecosystems, Mission Atlantic will contribute to a better and more sustainable future for life on Earth.”

The Marine Institute is leading the IEA approach for each of the seven case study areas throughout the Atlantic. In the Celtic Sea, this will be underpinned by regional data from INFOMAR, Ireland’s ongoing seabed mapping programme.

Marine Institite chief executive Dr Paul Connolly said: “The comprehensive mapping of the depth, character and benthic habitat of our seabed is critical to assess change, manage resources and risks, and to predict understand and realise the potential of our marine resource.”

Mission Atlantic will also focus on improving education, professional development opportunities and maritime policy in countries that border the Atlantic Ocean, north and south.

More information on the project will be available soon at www.missionatlantic.eu

A new Master’s course specialising in remote sensing and the principles of seabed mapping has been successfully delivered by a joint partnership between the Department of Geography at the Maynooth University and Ireland’s marine mapping programme INFOMAR.

The level 9 post-graduate module teaches students about the science of seabed mapping by providing a combination of class-based learning and practical offshore survey experience.

The course outlines the importance and impact of seabed mapping, and features a range of topics including how seabed data are collected and processed to produce high resolution maps of seafloor depth, type and habitat.

Lectures illustrate how scientists measure and describe the seafloor in incredible detail, using state of the art acoustic sonar, positioning, and optical instrumentation.

The use of satellite imagery analysis is explained in studying coastal seabed depth and shape, with practical examples utilising images of Dublin Bay acquired on the Sentinel-2 satellite’s sensor almost 800km above the Earth’s surface.

The module includes a two-day offshore practical where students are given an opportunity to apply the theoretical learning aboard the RV Celtic Voyager.

This is one of six survey platforms deployed by INFOMAR during seabed mapping operations, tasked with operating along the continental shelf and coastal waters.

Students get exposure to the dry and wet/chemical laboratories, as well as to operating an array of scientific equipment including the multibeam sonars and associated oceanographic instrumentation.

Participants boarded the RV Celtic Voyager in the Port of Cork and departed to the outer reaches of Cork Harbour where the offshore element of the module was conducted successfully on 15 and 16 February.

Training activities undertaken onboard included a marine mammal observation deck watch, survey computers and software use, benthic ecology, sedimentology classification, sound velocity probe deployment, multibeam echosounder, and sub-bottom profiler data gathering.

‘This module … demonstrates the welcome influence of Irish seabed mapping expertise on new sectors of society’

After exposure to the scientific equipment, workflows and data processing onboard, the students were tasked with the design, planning and implementation of a real-life survey scenario. This enabled them to apply their newly acquired seabed mapping knowledge as a team of scientists would in real-world conditions.

Overall the INFOMAR MSc module gave Maynooth students an overview of remote sensing techniques, helping them to understand bathymetric data products, to recognise data limitations, and to identify key systems and practices used in the field of seafloor surveying.

Students also developed a technical grounding in mapping at different resolutions, and the importance of instrumentation calibration, quality control and processing of bathymetry datasets, before product delivery to end users.

In addition, students learned how to source marine data online from INFOMAR’s Interactive Web Data Delivery System and online Webviewers, and via web-based portals operated by the European Marine Observation and Data Network (EMODnet) and the Copernicus Marine Environment Service.

Importantly, says the Marine Institute, the module was taught within the context of end users, stakeholders and the policy framework underpinning ocean science and ocean literacy, highlighting both the relevance and importance of mapping the Earth’s seafloor.

Participants benefited from the fact that the course was delivered directly by the INFOMAR team, who have extensive experience of offshore surveying, and were able to share their own experiences and varied employment backgrounds with the students.

Sean Cullen, of the Geological Survey Ireland and INFOMAR joint programme manager, said: “I’m pleased to see the very positive feedback on the course overall both from the students and the tutors.

“This module, newly developed by the INFOMAR team, with steering from the Department of Geography at Maynooth, demonstrates the welcome influence of Irish seabed mapping expertise on new sectors of society and is timely addition to the INFOMAR education initiative as we face into the United Nations Decade of Ocean Science for Sustainable Development.

“The collaboration is an encouraging sign that seabed science belongs in the space of third level education, and sets to further promote Ireland as leaders in marine science and of ocean literacy on an international stage.”

Thomas Furey, INFOMAR joint programme manager from the Marine Institute, added: “It is critical that we create a legacy to build on Ireland’s world leading role in seabed mapping, and through launching our third level delivery of INFOMAR specific training, we are contributing to capacity build, marine economy growth, and Ireland’s marine plan, Harnessing Our Ocean Wealth.”

The annual INFOMAR Seminar is a celebration of the year’s work by Ireland’s national seabed mapping programme. INFOMAR is funded by the Department of Communications, Climate Action and Environment and is jointly managed and operated by Geological Survey Ireland and the Marine Institute.

Attendees at the seminar, which will be held in Dingle, Co Kerry, on 16 and 17 October, will be among the first to see details of more than 8,500 of seafloor mapped, over 20 shipwrecks surveyed, and new 3D visuals of the coastal landscapes developed during the 2019 survey season.

The event will focus on Irish seabed mapping activities related to marine science, biodiversity, heritage and tourism in coastal communities. The event will feature an exciting line-up of experts presenting on; shipwreck mapping and archaeology, ocean literacy, marine ecology, ocean energy and infrastructure, as well as submerged and coastal landscapes and the connection between marine tourism and Fáilte Ireland’s Wild Atlantic Way.

Koen Verbruggen, Director of Geological Survey Ireland stated; “The INFOMAR seabed mapping programme continues to create significant positive impact at national, European and international levels, however this year’s annual conference in Dingle, Co Kerry, reflects INFOMAR’s prioritisation of engagement with local maritime communities who remain key stakeholders in Ireland’s national seabed mapping programme.”

“Ireland is an exemplar internationally in demonstrating best practice in ocean governance, through mapping, observing, predicting and managing our marine territory and resources. Connecting society with the value and importance of our ocean wealth is critical if we are to address today’s challenges, including climate change and population growth” said Dr. Peter Heffernan, CEO, Marine Institute.

Minister Canney stated; “INFOMAR, Ireland’s internationally renowned seabed mapping programme is an impressive example of inter-agency cooperation within the Government of Ireland. By holding its annual seminar event in Dingle Co. Kerry, I’m delighted to see the programme engage with its stakeholders at a local level, conveying its role in supporting the development of industry, research, heritage and tourism within coastal maritime communities”.

An Irish-led, international team of marine scientists on board the RV Celtic Explorer recently completed the third and final leg of an extensive offshore reef study using the Marine Institute’s remote operated vehicle (ROV) Holland 1.

The 21-day expedition investigating sensitive deep-sea habitats at the outer extent of the continental shelf off the southwest of Ireland was part of the SeaRover (Sensitive Ecosystem Assessment and ROV Exploration of Reef) project.

During their time at sea, the survey team mapped 154 separate locations within Ireland's marine territory, in what the Marine Institute describes as one of the most significant deep water benthic habitat assessments undertaken in this country.

The data and findings will contribute to good fisheries practice and the sustainable management of Ireland's marine biodiversity, the institute adds.

The survey used the ROV Holland 1 to capture high-definition footage of reef habitats up to 3000 metres deep, and to recover biological and sediment samples from 52 locations along the continental margin.

“Sensitive reef habitats form fragile ecosystems and attract a variety of marine species, such as sea pens, sponges, fish and crustaceans,” said survey chief scientist Yvonne Leahy, of the National Parks and Wildlife Service (NPWS).

“Surveying these habitats enables us to better understand Ireland’s deep sea territory so that we can protect and monitor our marine biodiversity and sustainably manage Ireland's marine resources effectively.”

Scientists from NUI Galway and University of Plymouth also joined the expedition to gather a range of biological samples to enable further research into population genetics studies, ecological modelling, and the harvesting of sponges for potential novel compounds for use in bio-medical applications.

Sediment samples will also be utilised for microplastics studies by NUI Galway and Galway-Mayo Institute of Technology (GMIT).

The three SeaRover surveys between since 2017 have involved a combined 63 days at sea, recorded 332 hours of high-definition video from the seafloor — almost 14 days of footage — and have undertaken detailed studies of 350km of seabed along a shelf extent of nearly 2,500km.

The surveys have explored 154 different locations along Ireland’s continental margin, including the Rockall and Porcupine Banks, the Goban Spur and the Whittard Canyon.

The HD camera picks up fine detail of deep-water coral species. The first SeaRover survey in 2017 included the discovery of the deepest known occurrence of the cold-water coral Solenosmilia variabilis, forming reefs in Irish waters at depths of 1,600m.

In 2018 the team discovered a rare shark nursery, 200 miles west of Ireland. A large number of egg cases were filmed on the seafloor at depths reaching 750m, and a large school of blackmouth catshark (Galeus melastomus) were present at the site. There were also numerous recordings of different coral species observed in Irish waters for the first time.

“After three years, the survey team has created an extensive data set which represents one of the most comprehensive assessments of Ireland's marine biodiversity,” said Leonie O'Dowd, Marine Institute section manager and European Maritime and Fisheries Fund (EMFF) programme co-ordinator.

“The success of these surveys is thanks to the coordination and collaboration across many organisations and government departments, and will benefit national policy development as well as researchers and scientists exploring our marine territory in the future.”

Thomas Furey, the Marine Institute’s joint INFOMAR programme manager, added: “It is fantastic to see the underlying INFOMAR seabed mapping data being used to strategically identify and target such vulnerable marine ecosystems for detailed studies in support of future marine management plans.

“In funding INFOMAR, the Department of Communications, Climate Action and Environment are supporting key evidence based investigations of our ever changing marine environment.”

The three-year SeaRover project was commissioned and jointly funded by the Irish Government and the EU’s European Maritime and Fisheries Fund (EMFF).

The cross-government initiative was supported by the Department of Agriculture, Food and Marine, Department of Culture, Heritage and Gaeltacht, and Department of Communications, Climate Action and Environment as part of the Marine Institute’s implementation of the EMFF Marine Biodiversity scheme.

Survey operations were led by the Marine Institute, INFOMAR and NPWS, accompanied by scientists from NUI Galway and the Marine Biology and Ecology Research Centre at the University of Plymouth, and supported by scientists in Geological Survey Ireland and the Norwegian Marine Institute.

#MarineScience - The extensive work carried out jointly by the Marine Institute and Geological Survey Ireland through the INFOMAR programme received substantial exposure and recognition at the 16th Forum for the Exchange of Mutual Multibeam Experiences (FEMME) in Bordeaux last week.

Hosted by the Kongsberg Maritime User Forum and focussing on seabed mapping, FEMME provides an international platform for hydrographic professionals to meet, exchange experiences and ideas, provide inspiration and contribute to improved system performance and the future of underwater mapping technologies.

High-profile attendees include the secretary general of the International Hydrographic Organization (IHO), chief hydrographers from the Service Hydrographique et Océanographique de la Marine (SHOM), and Seabed 2030 leaders.

An overview of the Department of Communications, Climate Action and Environment-funded INFOMAR programme was provided by Dr Fabio Sacchetti, who updated the audience on future plans as well as recent achievements of the Irish national seabed mapping initiative.

Dr Sacchetti highlighted 10 case studies featuring multiple applications of multibeam technologies in support of sectors including coastal engineering, marine conservation and marine heritage and tourism.

In addition, a recent high-profile collaboration between INFOMAR and various US and Canadian research institutes was presented by international research partners in attendance.

INFOMAR featured prominently in a talk by Prof John Hughes Clarke (CCOM/University of New Hampshire) when describing research into the impact of internal wave activity on multibeam bathymetry in an Irish/Celtic Sea context, based on work conducted onboard the RV Celtic Explorer.

Prof Clarke has been collaborating with INFOMAR since 2015, and he is particularly focused on using hydrographic and fisheries sonar systems, combined with oceanographic data, to gain a deeper understanding of the dynamics and complexities of the Celtic Sea.

Jose Cordero, of Instituto Hidrografico dela Marina (Spain), demonstrated how improved sound speed control through remotely detecting thermocline undulations can be achieved.

The study was the result of a collaboration carried out in 2017 onboard the RV Celtic Explorer during a routine INFOMAR survey.

Finally, Anand D Hiroji (HSRC/University of Southern Mississippi) showed how unambiguous radiation pattern extraction methods can improve data derived from multisector multibeam Sonars. Once again, this study was carried out using data acquired by INFOMAR onboard the RV Celtic Explorer.

As Ireland continues toward completion of its seabed mapping programme in 2026, the Marine Institute says it is “widely acknowledged internationally” that our best practice approach towards open and integrated data acquisition, integration and exploitation “is a valued model, and one which gives Irish researchers and technology developers a global audience, and market.”

#MarineScience - A multinational team of ocean exploration experts returned to Galway on World Ocean Day (Friday 8 June) after spending the last few weeks exploring and mapping the Charlie-Gibbs Fracture Zone of the Mid-Atlantic Ridge.

Using the robotic mini-sub ROV Holland I, the TOSCA (Tectonic Spreading and the Charlie-Gibbs Fracture Zone) research team led by Dr Aggie Georgiopoulou of UCD collected “spectacular” film footage of sponge gardens.

In another first for deep-sea exploration, the marine science team on board the RV Celtic Explorer also found more than 70 skate eggs in a nursery some 2,000 metres below the surface.

“Up to 150 rock and sediment samples amounting to roughly 200kg along with 86 hours of video footage and over 10,000 square kilometres of the zone were also mapped, which is almost the size of Co Galway and Co Mayo together,” Dr Georgiopoulou said.

The Charlie-Gibbs Fracture Zone was mapped for the first time in 2015 on the RV Celtic Explorer as one of the key projects launched by the Atlantic Ocean Research Alliance, following the signing of the Galway Statement on Atlantic Ocean Cooperation between Canada, the EU and the US in May 2013.

“The high resolution data produced by Ireland’s INFOMAR programme in 2015, that revealed spectacular landscape with 4,000m-high mounds rising from the seabed to 600m below the sea surface — taller than Carrauntoohil, Ireland’s highest mountain — has been instrumental in our continued research over the last month,” Dr Georgiopoulou said.

The tectonic spreading at the Charlie-Gibbs Fracture Zone consists of two huge parallel cracks in the crust of the Atlantic Ocean running between Ireland and Newfoundland, and is the longest-lived fracture zone in the Atlantic. It is the most prominent feature interrupting and offsetting the Mid-Atlantic Ridge.

“What we have found at the Charlie-Gibbs Fracture Zone surpassed all of our expectations,” Dr Georgiopoulou added. “Exploring three mountain areas, 500-1,000m-high scarps were discovered that have been produced by catastrophic rock avalanches, with giant boulder fields spilling into the fractures.

“Although these fracture zones are similar to the San Andreas fault in the western US and the North Anatolian fault in Turkey and Greece, with large earthquakes taking place there regularly, this is the first time there has been a dedicated geological study in the Charlie-Gibbs Fracture Zone area.”

The TOSCA expedition involved 13 scientists from nine institutions and five different countries including Ireland, the UK, Germany, Canada and Greece.

Experts in seabed mapping, marine geology, oceanography and marine biology, each team will return to their respective Institutes to analyse all the data and work out how the mountains were formed, when and how the rock avalanches take place and how the geology affects the local habitat for marine wildlife.

Marine Institute chief executive Dr Peter Heffernan congratulated the team on their recent discoveries, stating that deep ocean expeditions cannot be taken for granted as we need to better understand the features that make up the ocean seabed.

“With the ocean affecting climate change, global population and seafood demand, we need to map our seabed to define favourable habitats for fishing, key sites for conservation, and safe navigation for shipping.

“The expedition supported by AORA also reflects the value and essential role of international partnerships, particularly with achieving the shared goals of the Galway Statement on Atlantic Ocean Cooperation 2013, which include our ongoing cooperation on ocean science and observation in the Atlantic Ocean,” Dr Heffernan said.

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.
