The latest Marine Notice from the Department of Transport advises that INFOMAR will undertake a hydrographic and geographic survey operation in the Celtic Sea and Atlantic Ocean for six months from this April.

The massive operation will involve research vessels from Geological Survey Ireland (Keary, Geo, Lir, Gale and Mallet) and the Marine Institute (Celtic Voyager and Celtic Explorer) in a variety of surveys — along the South-West Coast from Roaringwater Bay to Kilkee, and offshore south of Mizen Head and between Kerry Head and the Aran Islands.

All vessels will be listening on VHF Channel 16 throughout the survey, and will display appropriate lights and markers. The RVs Celtic Voyager and Celtic Explorer will also be towing a magnetometer sensor with a single cable up to 200m in length, and a moving vessel profiler cable of variable length up to 200m.

Full details of the surveys, including dates, maps and coordinates, can be found in Marine Notice No 10 of 2021, a PDF of which can be downloaded below.

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.

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.”

Ireland's Offshore Renewable Energy

Because of Ireland's location at the Atlantic edge of the EU, it has more offshore energy potential than most other countries in Europe. The conditions are suitable for the development of the full range of current offshore renewable energy technologies.

Offshore Renewable Energy FAQs

Offshore renewable energy draws on the natural energy provided by wind, wave and tide to convert it into electricity for industry and domestic consumption.

Offshore wind is the most advanced technology, using fixed wind turbines in coastal areas, while floating wind is a developing technology more suited to deeper water. In 2018, offshore wind provided a tiny fraction of global electricity supply, but it is set to expand strongly in the coming decades into a USD 1 trillion business, according to the International Energy Agency (IEA). It says that turbines are growing in size and in power capacity, which in turn is "delivering major performance and cost improvements for offshore wind farms".

The global offshore wind market grew nearly 30% per year between 2010 and 2018, according to the IEA, due to rapid technology improvements, It calculated that about 150 new offshore wind projects are in active development around the world. Europe in particular has fostered the technology's development, led by Britain, Germany and Denmark, but China added more capacity than any other country in 2018.

A report for the Irish Wind Energy Assocation (IWEA) by the Carbon Trust – a British government-backed limited company established to accelerate Britain's move to a low carbon economy - says there are currently 14 fixed-bottom wind energy projects, four floating wind projects and one project that has yet to choose a technology at some stage of development in Irish waters. Some of these projects are aiming to build before 2030 to contribute to the 5GW target set by the Irish government, and others are expected to build after 2030. These projects have to secure planning permission, obtain a grid connection and also be successful in a competitive auction in the Renewable Electricity Support Scheme (RESS).

The electricity generated by each turbine is collected by an offshore electricity substation located within the wind farm. Seabed cables connect the offshore substation to an onshore substation on the coast. These cables transport the electricity to land from where it will be used to power homes, farms and businesses around Ireland. The offshore developer works with EirGrid, which operates the national grid, to identify how best to do this and where exactly on the grid the project should connect.

The new Marine Planning and Development Management Bill will create a new streamlined system for planning permission for activity or infrastructure in Irish waters or on the seabed, including offshore wind farms. It is due to be published before the end of 2020 and enacted in 2021.

There are a number of companies aiming to develop offshore wind energy off the Irish coast and some of the larger ones would be ESB, SSE Renewables, Energia, Statkraft and RWE.

There are a number of companies aiming to develop offshore wind energy off the Irish coast and some of the larger ones would be ESB, SSE Renewables, Energia, Statkraft and RWE. Is there scope for community involvement in offshore wind? The IWEA says that from the early stages of a project, the wind farm developer "should be engaging with the local community to inform them about the project, answer their questions and listen to their concerns". It says this provides the community with "the opportunity to work with the developer to help shape the final layout and design of the project". Listening to fishing industry concerns, and how fishermen may be affected by survey works, construction and eventual operation of a project is "of particular concern to developers", the IWEA says. It says there will also be a community benefit fund put in place for each project. It says the final details of this will be addressed in the design of the RESS (see below) for offshore wind but it has the potential to be "tens of millions of euro over the 15 years of the RESS contract". The Government is also considering the possibility that communities will be enabled to invest in offshore wind farms though there is "no clarity yet on how this would work", the IWEA says.

Based on current plans, it would amount to around 12 GW of offshore wind energy. However, the IWEA points out that is unlikely that all of the projects planned will be completed. The industry says there is even more significant potential for floating offshore wind off Ireland's west coast and the Programme for Government contains a commitment to develop a long-term plan for at least 30 GW of floating offshore wind in our deeper waters.

There are many different models of turbines. The larger a turbine, the more efficient it is in producing electricity at a good price. In choosing a turbine model the developer will be conscious of this ,but also has to be aware the impact of the turbine on the environment, marine life, biodiversity and visual impact. As a broad rule an offshore wind turbine will have a tip-height of between 165m and 215m tall. However, turbine technology is evolving at a rapid rate with larger more efficient turbines anticipated on the market in the coming years.

 

The Renewable Electricity Support Scheme is designed to support the development of renewable energy projects in Ireland. Under the scheme wind farms and solar farms compete against each other in an auction with the projects which offer power at the lowest price awarded contracts. These contracts provide them with a guaranteed price for their power for 15 years. If they obtain a better price for their electricity on the wholesale market they must return the difference to the consumer.

Yes. The first auction for offshore renewable energy projects is expected to take place in late 2021.

Cost is one difference, and technology is another. Floating wind farm technology is relatively new, but allows use of deeper water. Ireland's 50-metre contour line is the limit for traditional bottom-fixed wind farms, and it is also very close to population centres, which makes visibility of large turbines an issue - hence the attraction of floating structures Do offshore wind farms pose a navigational hazard to shipping? Inshore fishermen do have valid concerns. One of the first steps in identifying a site as a potential location for an offshore wind farm is to identify and assess the level of existing marine activity in the area and this particularly includes shipping. The National Marine Planning Framework aims to create, for the first time, a plan to balance the various kinds of offshore activity with the protection of the Irish marine environment. This is expected to be published before the end of 2020, and will set out clearly where is suitable for offshore renewable energy development and where it is not - due, for example, to shipping movements and safe navigation.

YEnvironmental organisations are concerned about the impact of turbines on bird populations, particularly migrating birds. A Danish scientific study published in 2019 found evidence that larger birds were tending to avoid turbine blades, but said it didn't have sufficient evidence for smaller birds – and cautioned that the cumulative effect of farms could still have an impact on bird movements. A full environmental impact assessment has to be carried out before a developer can apply for planning permission to develop an offshore wind farm. This would include desk-based studies as well as extensive surveys of the population and movements of birds and marine mammals, as well as fish and seabed habitats. If a potential environmental impact is identified the developer must, as part of the planning application, show how the project will be designed in such a way as to avoid the impact or to mitigate against it.

A typical 500 MW offshore wind farm would require an operations and maintenance base which would be on the nearby coast. Such a project would generally create between 80-100 fulltime jobs, according to the IWEA. There would also be a substantial increase to in-direct employment and associated socio-economic benefit to the surrounding area where the operation and maintenance hub is located.

The recent Carbon Trust report for the IWEA, entitled Harnessing our potential, identified significant skills shortages for offshore wind in Ireland across the areas of engineering financial services and logistics. The IWEA says that as Ireland is a relatively new entrant to the offshore wind market, there are "opportunities to develop and implement strategies to address the skills shortages for delivering offshore wind and for Ireland to be a net exporter of human capital and skills to the highly competitive global offshore wind supply chain". Offshore wind requires a diverse workforce with jobs in both transferable (for example from the oil and gas sector) and specialist disciplines across apprenticeships and higher education. IWEA have a training network called the Green Tech Skillnet that facilitates training and networking opportunities in the renewable energy sector.

It is expected that developing the 3.5 GW of offshore wind energy identified in the Government's Climate Action Plan would create around 2,500 jobs in construction and development and around 700 permanent operations and maintenance jobs. The Programme for Government published in 2020 has an enhanced target of 5 GW of offshore wind which would create even more employment. The industry says that in the initial stages, the development of offshore wind energy would create employment in conducting environmental surveys, community engagement and development applications for planning. As a site moves to construction, people with backgrounds in various types of engineering, marine construction and marine transport would be recruited. Once the site is up and running , a project requires a team of turbine technicians, engineers and administrators to ensure the wind farm is fully and properly maintained, as well as crew for the crew transfer vessels transporting workers from shore to the turbines.

The IEA says that today's offshore wind market "doesn't even come close to tapping the full potential – with high-quality resources available in most major markets". It estimates that offshore wind has the potential to generate more than 420 000 Terawatt hours per year (TWh/yr) worldwide – as in more than 18 times the current global electricity demand. One Terawatt is 114 megawatts, and to put it in context, Scotland it has a population a little over 5 million and requires 25 TWh/yr of electrical energy.

Not as advanced as wind, with anchoring a big challenge – given that the most effective wave energy has to be in the most energetic locations, such as the Irish west coast. Britain, Ireland and Portugal are regarded as most advanced in developing wave energy technology. The prize is significant, the industry says, as there are forecasts that varying between 4000TWh/yr to 29500TWh/yr. Europe consumes around 3000TWh/year.

The industry has two main umbrella organisations – the Irish Wind Energy Association, which represents both onshore and offshore wind, and the Marine Renewables Industry Association, which focuses on all types of renewable in the marine environment.
