Scientists at NUI Galway warn that a deadly bacteria found in many highly rated sea swimming spots in Ireland is not currently tested for as EU regulations do not require it.

According to The Irish Independent, reseaechers with NUI Galway’s PIER Project found that more than half (57%) of all samples it collected from coastal bathing areas tested positive for Shiga toxigenic Escherichia coli (STEC).

Lake and river bathing areas fared even worse, with 78% of sites samples showing signs of the particularly virulent form of E. coli.

The researchers said all of the sampled sea bathing areas — in Galway, Cork and Fingal — that had STEC present have been rated good to excellent for water quality by EU standards.

“These findings highlight the need to consider revision of current EU bathing water quality monitoring criteria,” the PIER Project’s Professor Dearbháile Morris said.

More than 90% of samples taken from Irish rivers show the presence of E. coli, according to a new study from NUI Galway.

And researchers found that the toxic bacteria was also present in bathing waters which pass muster with the EU’s water quality criteria.

Prof Dearbháile Morris and Dr Louise O’Connor at the School of Medicine, NUI Galway, led the study which is due to be presented at this year’s European Congress on Clinical Microbiology and Infectious Diseases.

With European data showing Ireland has had the highest incidence of human infection with Shiga-toxigenic E. coli (STEC) among EU member states for many years — reporting 10 times the EU average in 2017 — the team looked at recreational waters for the presence of the bacteria.

Overall, nearly two thirds of the 75 samples (65%) tested positive for genetic markers of STEC. More than half (56%) of seawater samples were positive, as were three quarters of lake samples.

But just one of 15 river samples tested showed no trace of STEC.

Prof Morris says the high detection rate highlights “the need for further investigation to establish the scale of the problem, not only in Ireland but globally”.

This includes bathing waters in Europe and elsewhere which “are not routinely monitored for the presence of STEC”.

Microplastic ingested by plankton may greatly impair our oceans’ natural carbon-capturing abilities, according to a new study from NUI Galway.

Marine scientists at the university’s Ryan Institute found that microscopic particles of plastic waste in the world’s oceans are interfering with the food chain that cycles CO2 from the surface to the floor, as The Irish Times reports.

The cycle involves the absorption of CO2 from the atmosphere by algae on the ocean surface via photosynthesis. This algae is a food source for zooplankton such as salps, whose faecal matter sinks to the ocean floor.

As much as half of all CO2 produced by humans over the last 200 years has been captured at the bottom of the world’s oceans in this manner, the scientists say.

However, the team have identified that when salps ingest algae along with microplastic particles, their excretions do not sink to the bottom as fast, and may be broken down closer to the surface to release more of their trapped CO2.

“It is very important to point out our study was carried out in a laboratory,” said Dr Tom Doyle of UCC, a partner in the research.

“We now need to go out into the field to further test our hypothesis by quantifying the abundance of microplastics found in salps and their faecal pellets in different areas of our oceans.”

#NewsUpdate - The Defence Forces Review 2018, in association with the School of Political Science and Sociology will be held in NUI Galway next week, on Thursday 22 November.

The event is also been held with the Irish Centre for Human Rights, at the National University of Galway. The Review entilted Peacekeeping & Peacemaking Interventions, is open to the public and free of charge to attend (registration at 9pm) for event starting at 10am in the college's Aula Maxima. 

2018 represents the 60th Anniversary of when in 1958 Irish troops were first deployed on a UN mission since the foundation of the State as Military Observers (UNMOs) in Lebanon. It is also the 40th Anniversary of an Irish Infantry Battalion being deployed to UNIFIL in South Lebanon, where the Defence Forces maintains a significant presence.

It is therefore fitting that this years edition of the DF Review should examine a key debate for our times, namely the evolution, development and indeed relevance of Peacekeeping and Peacemaking Interventions; a debate never more focused in view of the continuing catastrophic conflict in Syria and the ripple effects of same including the ongoing refugee crisis.

#MarineScience - Researchers at Trinity College Dublin have identified ‘super healing’ capabilities in limpets, as Trinity News reports.

The small molluscs, which can be found in coastal areas all around the world, were studied for a paper in the Journal of the Royal Society Interface.

Trinity scientists found that the limpets they studied were able to sense minor damage to their shells from weathering or predator attacks, and repair them much in the way mammals heal broken bones.

Meanwhile, sea sponges recently discovered in Ireland’s deep ocean territory could hold special medicinal properties, according to The Irish Times.

Samples taken during the recent Marine Institute expedition are being tested for their effectiveness in treating cancer, Parkinson’s disease, Huntington’s disease, epilepsy and other conditions.

The relevant chemicals are produced by the sponges as part of their defences against competing marine organisms, and NUI Galway’s Dr Louise Alcock hopes to see positive results within the next year.

#MarineScience - NUI Galway will host a public seminar examining ocean acidification next Wednesday 16 September.

Ocean acidification arises as a result of the ongoing decrease in the pH of the Earth’s oceans, caused by the uptake of carbon dioxide from the atmosphere.

One of the world-leading authorities on ocean acidification, Dr Richard Feely of the National Oceanic and Atmospheric Administration (NOAA) Pacific Marine Environmental Laboratory in Seattle will discuss the present and future implications of increased carbon dioxide levels on the health of our ocean ecosystems and related ocean-based economies.

The lecture will take place at 7.30pm in the Aula Maxima at NUI Galway and is free to the public. Advance registration is advised as the number of places is limited. To register click HERE.

#deepsea – An international research team, led by scientists from NUI Galway, is currently exploring the Whittard Canyon deep-sea submarine canyon system in the North East Atlantic onboard the Marine Institute's RV Celtic Explorer.

Researchers from Ireland, the UK, the USA and Germany are using the Institute's ROV Holland I to study the diversity of deep-water animals and relate this to geology and ocean currents.

The Whittard Canyon system is at the continental margin approximately 250 miles SW of Cork, covers an area of 2000 square miles, and is home to vulnerable marine ecosystems of cold-water corals, deep-water oysters and file clams. But new research is also revealing a remarkable diversity and abundance of rare black corals, which are protected under international legislation.

"The extreme shape of submarine canyons seems to affect the water flow within them in such a way as to deliver nutrient rich waters to particular parts of the canyon system. This allows diverse ecosystems to flourish. Our research is attempting to understand these processes so that we can predict where the most vulnerable ecosystems are likely to occur and therefore ensure the environment is protected," explained Dr Martin White of NUI Galway's Ryan Institute, and the expedition's chief scientist.

According to Dr Louise Allcock, also of NUI Galway's Ryan Institute, "Black corals are particularly vulnerable to any sort of impact. They grow extremely slowly and dating studies have shown that some species live for thousands of years."

The Whittard Canyon system is huge, with meandering branches extending over an area of more than 80 by 20 miles. Mapping the system, much of which is in depths below 1500m, to detect vulnerable species is difficult. Therefore the team hopes that the new data will reveal the factors that determine which species occur where.

ROV Holland I provides a way of sampling deep-sea animals without impacting the ecosystem. The team is also providing deep-sea sponge samples to scientists searching for novel pharmaceutical compounds. If the chemists find interesting compounds such as antibacterial and other pharmaceutical properties in the sponges, they will aim to work out how to synthesize them in the laboratory. This is the first step in the production of new drugs.

The scientists are blogging about their experiences and discoveries aboard RV Celtic Explorer throughout the survey (June 6th – 21st) on the blog scientistsatsea.blogspot.ie and on twitter via the hashtag #ce14009

The research survey is carried out under the Sea Change strategy with the support of the Marine Institute, funded under the Marine Research Sub-Programme by the Irish Government.

#boatofthe year – The NUI Galway campaign sailing Martin Breen's Galway Reflex 38 yacht has been named ICRA's Boat of the Year. The prize was presented in Kilkenny this afternoon and applauded by a wide cross section of delegates at the one day ICRA conference including leading sail makers, race organisers, Olympic race officer Jack Roy and Volvo Ocean Race (VOR) champion Damian Foxall.

The NUI campaign was picked ahead of six other boats shortlisted for the prize.

NUI Galway campaign manager Cathal Clarke said the boat's aim in 2012 was to inspire other sailors from the West Coast to undertake similar projects and for the next generation of Volvo Ocean Race sailors to get out there and get sailing.

The ICRA Judges said the student based campaign embodied the spirit of ICRA with a campaign that featured competition in many venues around the country.

Following an overall win in the 2011 Dun Laoghaire to Dingle Race as 'Galway Harbour' Martin Breen's Reflex 38 was prepared for the 2012 Round Ireland by students of NUIG and raced as 'NUIGALWAY'. The students won Class 2 and were the first Irish fixed keel boat, finishing sixth overall.

They were also class 1 winners in the Pwllheli to Wicklow ISORA race in preparation for June's Round Ireland race.

The boat is raced by a separate inshore crew and in 2012 they competed in the 2012 ICRA Nationals in Howth, Cork Week and Calves Week. In 2013 they will plan to race at the ICRA Nationals in Fenit and also in the Sovereigns Cup in Kinsale.

The NUI Galway Round Ireland crew were Ben Scallan (helm), Eoghan McGregor (helm), Joan Mulloy (trimmer), Mark Armstrong (trimmer), Cathal Clarke (trimmer), Back row (left to right) Eoin Breen (bowman), Conor Kinsella (Mainsail trimmer), David Fitzgerald, (bowman), Louis Mulloy (bowman) and Ruaidhri De Faoite (mainsail trimmer).

One of the main aims of NUI campaign was to promote the home-grown sailing talent in Galway. Boat skipper, Cathal Clarke said: "The vision of this project is to prove the wealth of sailing talent here on the west coast and to encourage the next generation of Volvo Ocean Race sailors to get out there and get sailing. We aim to inspire other sailors from the region to undertake such projects in the future."

#DIVING - The Sub-Aqua Club at NUI Galway and the Galway-Mayo Institute of Technology welcomes diving expert Edward Bourke to the NUI Galway campus on 18 October to give a talk on historical wreck diving in Ireland.

The talk will take a look at some of the exploits of wreck and salvage dives in Ireland over the years, exploring the nation of the Irish coast as a hotbed of pioneering subaquatic activity, driven mostly by the recovery of shipborne cannons - not only because of their expense, but also to prevent their falling into the hands of insurgents.

Bourke will give his talk at the Siobhán McKenna Theatre in the Arts Millennium Building at 7pm on Thursday 10 October. The evening will be of interest to local historians and divers alike. And as much of the activity was on the west coast, there is some local maritime interest, too.

Edward Bourke is a microbiologist, maritime historian and diver with Viking Sub Aqua in Dublin for 30 years and has dived in Australia, South Africa, Spain, Croatia, France and UK as well as Ireland. He has published three volumes on Shipwrecks of the Irish Coast, cataloguing some 6,000 wrecks in Irish waters, as well as a book of Irish shipwreck photos and a volume on the wreck of the Tayleur at Lambay Island. A scientist with Diageo, Bourke's most recent publication is a history of Guinness.

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.
