Concern has been expressed over reports of endangered loggerhead turtles washing up on Irish and British shores in recent days, as BreakingNews.ie reports.

The remains of a deceased loggerhead turtle were found at Port Glais in Co Mayo over the weekend, while a live turtle was recovered in Anglesey in North Wales across the Irish Sea.

Loggerhead turtles are rarely found in Irish waters, with the last known sighting being a 50kg adult female in Connemara in December 2021 which died soon after it was recovered.

The marine wildlife species’ normal habitat is the warmer waters of the eastern United States, the Caribbean and Gulf of Mexico. In much colder climes such as Ireland, they can suffer often lethal ‘cold shock’, particularly when stormy conditions bring on sudden drops in water temperature.

A loggerhead turtle believed to originate from the waters around the Canary Islands has died despite the best efforts of Galway Atlantaquaria staff after it was found washed ashore in Connemara.

As RTÉ News reports, the 50kg turtle was discovered on Muighinis Beach near Carna in a comatose state and on the advice of the Irish Whale and Dolphin Group was taken to the national aquarium in Salthill.

However, Galway Atlantaquaria confirmed on social media that the adult female loggerhead turtle “never regained consciousness”.

It’s suspected that the turtle, who had been named Macdara after the patron saint of Connemara fishers, was blown off course during Storm Barra earlier this month into the colder North Atlantic.

#MarineWildlife - There's good news to report from the Galway Atlantaquaria as Ninja the loggerhead turtle is out of intensive care.

As previously reported on Afloat.ie, the 'cold stunned' reptile was close to death when she was rescued by staff at the Seal Rescue Centre in Courtown, Co Wexford after washing up on a Kilmore Quay beach before Christmas.

She was shortly after transferred to the longer-term care facilities at the Salthill aquarium, where she was treated for frostbite and wounds to her skin and shell.

And according to The Irish Times, the turtle is now over the worst of her ordeal, though she's missing a flipper and her skin will require more treatment.

The same staff at Galway nursed Leona the loggerhead back to health before she was flown to the more suitable warmer climes of the Canary Islands just over a year ago.

#MarineWildlife - Columba, the young loggerhead turtle rescued from near freezing waters on the Donegal coast last week, has died.

As the Belfast Telegraph reports, staff at the Exploris aquarium in Portaferry fought hard to save the junior turtle's life after it was discovered hundreds of miles from the warmer waters of the Gulf Stream, but it sadly passed away on Monday night (26 January).

A post-mortem was scheduled to determine whether illness may have caused the 12-year-old reptile to veer so far off course into Ireland's dangerously cold winter waters.

But for every sad story, the marine wildlife rehab staff at Exploris have many more happy tales to tell.

Since 1989, the Co Down aquarium has rescued 187 common seals, 253 grey seals and 10 loggerheads, with the vast majority returned to the wild in full health.

And they've come to the sanctuary from all over Ireland, with 1990 in particular being a big year for rescues of loggerhead turtles at Achill Island, Galway Bay and Brandon Bay, the aquarium's first.

There are some unusual rescue animals, too, such as a white lobster found in Carnlough in Co Antrim four years ago. The Belfast Telegraph has much more HERE.

#MarineWildlife - Leona the Loggerhead's last known whereabouts put her swimming south of the Canary Islands after her successful release last week, according to The Irish Times.

The female sea turtle jetted off with Aer Lingus to the warmer waters off northwest Africa after almost a year in rehabilitation at the Galway Atlantaquaria, following her lucky discovery on a beach at Quilty, Co Clare.

As the video of her release shows, Leona took to the water with ease - after a little human help - and is now likely looking for suitable feeding grounds of the coast of Morocco.

“She hasn’t swum north yet – but if she does head northeast, we would hope she would head for the Mediterranean, where there is a turtle colony,” said Joanna Casserley, who flew with Leona in economy class to Las Palmas a week ago.

#MarineWildlife - There's some great news for Leon - or Leona - the loggerhead turtle, who will finally be jetting off to her new home next week.

According to RTÉ News, the Irish Whale and Dolphin Group (IWDG) has arranged special transport with Aer Lingus for the turtle, who spent much of this year being nursed back to health by Galway Atlantaquaria staff after she was found beached at Quilty in Co Clare last November.

Plans were made to relocate her to the much more hospitable climes of the Canary Islands last month, but safe transport was a stumbling block, prompting the IWDG to put out a call earlier this month for berthage on a private jet.

But thanks to the intervention of Dublin Zoo, Galway Atlantaquaria and Rod Penrose of the UK Cetacean Strandings Investigation Programme, suitable travel arrangements have been made with Are Lingus to fly the turtle - with two carers - direct to Las Palmas, from where her future exploits in the wild can be followed online.

#MarineWildlife - Leon, the loggerhead turtle nursed back to health over the past year, has been ready to return to the wild since last month, as plans were made to relocate her to warmer waters off the Canary Islands.

But as RTÉ News reports, the Irish Whale and Dolphin Group (IWDG) – which recovered Leon from a beach near Quilty in Co Clare last November – has struggled to find transport to get the turtle to her new home.

According to the IWDG's Dr Simon Berrow, flying her there by commercial airline is out of the question "due to issues with transport of live animals [and] long overnights in the hold in Madrid with no access to her".

However, passage on a private jet might be the answer - provided an accommodating owner can be found.

#MarineWildlife - The Irish Times reports on a change of plans for Leon the loggerhead turtle, who was expected to be released back onto the wild last month but is now headed for much warmer climes off the Canaries.

Leon has spent almost a year in rehabilitation under the care of staff at the Galway Atlantaquaria after she was found washed up in critical condition on a beach near Quilty in Co Clare last November.

Nursed back to full health as the months progressed, it was expected she would be released into the sea with a celebration at the Salthill aquarium on 21 September.

But the warmer waters in the turtle breeding grounds off the Canary Islands was thought a more appropriate spot for her reintroduction to the wild, and she's set to jet off in the next few days. More on the story HERE.

#MarineWildlife - The Clare Herald reports that a loggerhead turtle who stranded on a beach near Quilty in November year will soon be fit for release back into the sea.

As previously reported on Afloat.ie, Leon the loggerhead – named after the famous Quilty shipwreck – was rushed to the Galway Atlantaquarium for rehabilitation after a local woman spotted the rare visitor to Ireland's shores.

After some 10 months of care at the hands of the aquarium's marine wildlife experts, Leon is now set to return to the wild, with a big celebration planned for her release at the Salthill aquarium this Sunday 21 September.

#MarineWildlife - BBC News reports on the sad story of a nine-metre long minke whale found dead on the beach at Magilligan Point in Derry.

According to the Irish Whale and Dolphin Group's (IWDG) Pádraig Whooley, minke whales have been "reported with increased frequency off the Antrim and Down coast" and there have been sightings in he past week off Donegal.

The incident marks the third whale stranding on the Northern Irish coast since September, when two died after beaching in North Antrim.

In more positive marine wildlife news, a loggerhead turtles is being cared for at the Galway Atlantaquarium after stranding in a bad condition in Co Clare during the week.

The Irish Independent reports that the turtle, named Leon after the famous Quilty shipwreck, was recovered after a local woman alerted marine wildlife experts.

“You might see a loggerhead turtle wash up every couple or three years but not very often at all," said Dr Simon Berrow of the IWDG, who said the turtle may need several months' rehab before its fit to return to the wild.

That's an issue that presents its own challenges due to its smaller size and distance from its usual tropical waters.

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.
