#MarineScience - Celebrating 20 years of service in July was the Marine Institute's RV Celtic Voyager, the second decade reached marked a significant milestone for Ireland's first purpose built research vessel.

The RV Celtic Voyager was built in the Netherlands and arrived in Ireland in July 1997 to replace the RV Lough Beltra (1978 – 1997) as part of the national strategy to build Ireland's capabilities in marine research. "Moving from the 21m Lough Beltra that had originally been a trawler, to a 31.4m research vessel was the beginning of a new era in marine science in Ireland, where the Institute was able to provide a purpose built platform that could operate further out in our ocean territory. This enabled high quality research and monitoring informing decisions about Ireland's marine resource into the future," explained Mick Gillooly, Director of Ocean Science and Information services, Marine Institute.

The multi-purpose facilities on the vessel has allowed scientists to gather information covering a wide range of ocean sciences, including sea bed mapping and learning more about the marine species and environmental conditions.

Specially fitted with scientific equipment in wet, dry and chemical laboratories, having the ability to carry more scientists and being able to spend more time at sea which increased the output of science in Ireland. The Celtic Voyager, in its first full year of operation reached 260 operational days and the scientific output also increased by 150 percent over the output of the Lough Beltra. The vessel also exceeded original expectations about its range by carrying surveys further south in the Bay of Biscay and as far west as the Rockall Trough.

In the last 20 years, the vessel has successfully completed over 4,800 science days and has sailed over 380,000 nautical miles in the course of 595 science surveys in that period; and has had a positive impact on many Irish marine scientists and crew member's careers at sea.

Ireland's marine territory is over 880,000 square kilometres in the Atlantic, Irish and Celtic Seas, and with the INFOMAR Programme, in partnership with the Geological Survey of Ireland, the Marine Institute is completing one of the largest civilian seabed mapping projects in the world. As part of the INFOMAR programme, the RV Celtic Voyager has been responsible for mapping 30,000 square km Ireland's coastal and inshore area since 2007. Using multi-beam technology on the vessel, scientists have collected data producing high resolution maps showing the shape and type of the seabed below at depths between 20 - ~100m.

"Significant discoveries have been made on the Voyager ranging from mapping over 200 shipwrecks around the coast of Ireland including the RMS Lusitania, RMS Leinster and the Kowloon Bridge to revealing new information about the seafloor. In 2007 the survey of Galway Bay revealed for the first time a detailed seafloor and geology of the bay, confirming the location of the Galway Bay Fault, demarking the limits of Galway's granite landscape running northwest to southeast, between Lettermullan/Gorumna Islands in west Connemara and the Aran Islands," explained Thomas Fury, manager of the advanced mapping team at the Marine Institute.

The RV Celtic Voyager has also played an essential role in fisheries scientific research in Ireland, in particular ground fish stocks such as haddock and whiting since its launch in 1997, as well as developing unique underwater television survey methods to gather information the Dublin Bay prawn (Nephrops norvegicus) since 2002. "The capabilities of the vessel has enabled marine scientists to work in conditions allowing them to better recognise significant changes in the abundance and distribution of a wide range of marine species and changes in the environment; and in turn provide sound scientific advice about information on stock size, exploitation status and catch of commercial species," explained Dr Paul Connolly, Fisheries Ecosystems and Advisory services, Marine Institute.

The RV Celtic Voyager has provided scientists the ability to a learn about the oceans dynamic ecological systems as well as ensuring that Ireland complies with national and EU regulations relating to the assessment of water quality and marine food safety. "Initially the vessel was used for looking at the levels of nutrients and pollutants in coastal waters that were either naturally caused by environmental conditions or introduced by humans such as agriculture run off, shipping and industrial activities," explained Jeff Fisher, Marine Environment and Food Safety Services, Marine Institute.

Surveys over the last decade have however increased the level of research to include the collection and assessment of phytoplankton as an indicator of the health of the ocean; as well as recovering samples of sediments and sea bed organisms for biological, chemical and geological analysis so as to assess at the quality and long term changes to sediment dwelling marine species. In more recent years scientists have also used the Voyager for the collection of water and sediment samples to monitor the impacts of climate change, ocean acidification and the introduction of micro plastics to the marine environment.

Dr Peter Heffernan, CEO of the Marine Institute congratulated the research vessel operations team, crew, scientists and researchers that have worked on the RV Celtic Voyager over the last 20 years, stating that "coastal research and offshore surveys involving fisheries research, environmental monitoring, seabed mapping, oceanographic work, buoy maintenance and student training all highlight the importance of having the best resources available, producing the best marine science in Ireland".

"In the Voyager's 20th year it is therefore important to recognise the contribution the vessel has made in providing marine scientists, researchers and its crew members, with many years of valued experience at sea, expanding and strengthening marine science in Ireland to help inform decisions affecting our ocean. This increase in activity also contributed to the expansion of Ireland's international role and profile in sustainable marine research, development, innovation and management."

#MarineWildlife - A team of scientists on board the RV Celtic Voyager got more than they bargained for during a recent survey to understand the habitat use of elusive beaked whales.

That’s when they encountered four separate groups of breaching whales within a couple of hours near the Rockall Trough.

Very little is known about beaked whales as they are rarely encountered at sea and are shy around vessels. New species of the elusive marine mammals are being described as recently as last year.

In Ireland there are at least four species of beaked whales: Sowerby’s, True’s, Cuvier’s beaked whale and the northern bottlenose whale.

“We think that the groups encountered were either Sowerby’s or True’s beaked whale, possibly both, they are incredibly difficult to positively identify at sea,” said Dr Patricia Breen of NUI Galway, chief scientist on the survey.

“We know that they undertake huge dives to great depths of up to 2500m for an hour at a time. They feed mostly on squid but also deep sea fish.”

The recent survey was a collaborative study between NUI Galway, UCC, the Marine Institute, Centre for Marine and Renewable Energy, Marine Conservation Research and Washington State University.

The aim was to characterise beaked whale habitat using acoustic technology in a small study area, as the whales are more likely to be heard rather than seen.

As well as using a hydrophone to detect whale clicks the team also characterised the habitat by recording oceanographic information such as salinity, temperature and depth, as well as the fish and squid species in the area, their most likely food source.

Dr Ailbhe Kavanagh of UCC said: “We had seen a group of breaching beaked whales the previous day and upon finishing up our acoustic transects decided to return to the area we had sighted them in previously.

“While steaming through this area we encountered four groups of beaked whales, all breaching, and all groups of between two to four individuals.” Dr Breen added: “The amazing thing about this encounter was the high number of sightings in such a small and specific area. Less than 30km separated the first and last sightings.

“This highlights an area that, whilst small, is potentially of huge importance to beaked whales in Irish waters. We hope to investigate this area further in the future.” During the survey, the team caught many species of fish which live in the mesopelagic zone between 200m and 1000m deep.

“Recent studies have shown that some beaked whale species prey on both squid and mesopelagic fish,” said UCC’s Prof Emer Rogan. “It is likely that the fish species we were catching in our nets is the reason the whales are here, to feed.

“The information collected on this survey will we helpful in our efforts to learn more about the species and to ensure adequate protection of the habitat of beaked whales in Irish waters.”

The survey, which took place from Sunday 29 October to Monday 6 November, was funded through the national research vessels’ ship time programme. This research survey was carried out with the support of the Marine Institute, funded under the Marine Research Programme 2014-2020 by the Irish Government.

The Marine Institute’s ship time programme provides annual grant-aid to researchers to access ship-time to facilitate research projects/programmes and further develop the national potential to carry out world-class multidisciplinary marine research.

#MarineNotice - Mariners of the South Coast are advised that PSE Kinsale Energy will undertake a seabed mapping survey in the Kinsale Head and Seven Heads Gas Fields next week.

The survey is expected to begin on Monday 12 June and last for five or six days, subject to weather conditions.

The multi-beam mapping survey is to confirm the seabed status adjacent to subsea gas production infrastructure such as wellheads, manifolds and jacket/platform structures, collecting data for ongoing field maintenance operations and future planning.

The RV Celtic Voyager (Callsign EIQN) is scheduled to carry out the survey operations at specific locations to assess the status of the subsea infrastructure in relation to the adjacent seabed. A total of 15 multi-beam mapping locations are anticipated.

There will be a regular safety message broadcasting on VHF Channel 16 throughout the project. All vessels, particularly those engaged in fishing, are requested to give the RV Celtic
Voyager a wide berth and keep a sharp lookout in the relevant areas.

Full details of the survey area are included in Marine Notice No 24 of 2017, a PDF of which is available to read or download HERE.

#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.

The Marine Institute held the second bi-annual research vessel users conference today at its headquarters in Oranmore, Galway to discuss the vast range of capabilities of both the RV Celtic Explorer and RV Celtic Voyager after their 2015 refits, as well as the use of the remotely operated vehicle, ROV Holland 1.

Director Mick Gillooly of Ocean Science and Information Services, Marine Institute, welcomed the attendance of over 70 marine scientists and researchers who will go to sea on the national research vessels this year. He said: “The demand for survey time on the national research vessels and the quality marine research being carried out across the country shows that Ireland’s scientists are answering the call to better understand our oceans.”

“At a time when we can all see the impacts of climate change, it’s more important than ever to carry out research at sea, including oceanography, fisheries, and environmental monitoring.”

The conference provided information about using high resolution multi-beam mapping, the capabilities of the ROV Holland 1 on surveys as well as key speaker’s experiences using the equipment.

Dr Florian Le Pape of the Dublin Institute for Advanced Studies (DIAS) spoke about the deployment of an Ocean Bottom Seismometer (OBS) network off the Irish shelf as far as the Rockall Trough. Dr Le Pape recently deployed 10 Broad Band OBSs from the RV Celtic Explorer as part of an innovative research program between DIAS, the Helmholtz Centre GFZ Potsdam, Germany and instruments provided by the Alfred Wegener Institute, Germany, which uses the noise from ocean waves to generate seismic images of the earth’s crust.

Over 70 marine scientists attended the Research Vessel Users Conference at the Marine Institute. Deep sea mud volcanoes off the gulf of Cadiz and the high resolution multi-beam mapping of World War 1 shipwrecks in the Irish Sea highlighted the advanced capabilities of the research vessels for deep sea exploration.

The workshop was organised by the Marine Institute’s research vessel operations team also highlighted the value of ship time. Mr Aodhan Fitzgerald, Research Vessel Operations Manager, spoke about the future vessel availability, the ship-time competition for 2017, and how to prepare a strong research survey proposal.

The Marine Institute’s ship-time programme will provide €3 million funding in 2016 supporting 256 research days onboard the national research vessels, RV Celtic Explorer and RV Celtic Voyager. The programme gives researchers access to the national research vessels, as well as the remotely operated submarine ROV Holland I to carry out surveys that further our understanding of the ocean, support policy and development, as well as providing essential training to young researchers and undergraduates.

The programme is part of a busy schedule of research vessel programmes that includes statutory fish stock assessment, environmental monitoring, and seabed mapping surveys in Irish Waters and across the Atlantic basin to Newfoundland.

The Marine Institute’s Ship-Time Programme will fund 256 days at sea this year for marine science researchers to carry out surveys that will further our understanding of the ocean, support policy development, and provide essential training opportunities to young researchers and undergraduates. This is the tenth consecutive year of the Ship-Time Programme and it will provide €3m Euro in funding. The initiative provides access to the national research vessels, RV Celtic Explorer, and RV Celtic Voyager, as well a the ROV Holland I (remotely operated vehicle ). It represents just part of a very busy schedule of research vessel programmes that includes statutory fish stock assessment, environmental monitoring, and seabed mapping surveys.

Dr. Peter Heffernan, Marine Institute CEO, said the demand for ship-time and the quality of the applications was an indication of the standard of marine research being carried out in Ireland.

“Marine research in Ireland is being carried out to the highest standards and the strong demand for ship-time shows that Ireland’s scientists are answering the challenge to better understand our oceans”, said Dr. Heffernan. “At a time when we can all see the impacts of climate change, it’s more important than ever to carry out research at sea, including oceanography, fisheries, and environmental monitoring. We know that the ocean plays a key role in controlling the earth’s climate and we know that the microscopic plankton in the ocean produce half of the oxygen we breathe. The ocean is the life support system for the planet and therefore it is essential that we understand its impact on us, as well as our impacts on the ocean.”

The Ship-Time Programme funds surveys across three broad categories – research, policy support services and dedicated training programmes. The RV Celtic Voyager will be the platform for 15 Higher Education Institute led training programmes over 73 days throughout 2016. Last year over 390 students participated in training onboard the Celtic Voyager through this programme. The opportunity to spend time at sea on a working research vessel, planning, designing and carrying out research at sea is essential and invaluable experience for young scientists.

The RV Celtic Explorer will be the platform for eight research surveys under the Ship-time programme, while the RV Celtic Voyager will support ten research surveys under the initiative. Marine Institute scientists will lead seven of these surveys on both vessels in areas that support policy development and implementation.

Among the surveys taking place this year are a survey by the Dublin Institute for Advanced Studies monitoring part of the Irish shelf using ocean bottom seismometers in an innovative research program which uses the noise from ocean waves to generate seismic images of the earth’s crust (January 13-22); identifying the location of Sea Bass spawning areas (MI – March 16-29); exploring submarine canyon ecosystem services (NUI Galway June 1-20); and mapping and creating high resolution images of World War I ship wrecks (University of Ulster –September 3-9 ).

The provision of access to ship-time is identified as a key priority in Harnessing Our Ocean Wealth- An Integrated Marine Plan for Ireland. The Ship- time programme is funded under the Marine Research Programme 2014-2020 by the Irish Government. Applications for Ship Time funding are evaluated by a panel of 15 independent international experts (UK, European and US) and each application was reviewed by two or three evaluators.

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.
