At the end of January 2013, over a one week period, 13 common dolphins were found dead along the Mayo coast. The situation was considered sufficiently unusual to warrant further investigation. The Department of Arts, Heritage and the Gaeltacht commissioned a specialist cetacean veterinarian team to carry out post-mortem examinations on five of the animals. This work was undertaken in Athlone at the Regional Veterinary Laboratories of the Department of Agriculture, Food and the Marine.

There was evidence consistent with entanglement in fishing gear apparent in each animal and the post-mortem findings in all five animals are thought to be most consistent with accidental bycatch in trawl type fishery gear. Common dolphins are plentiful in Irish waters and the Celtic Sea, but are at risk of accidental bycatch by trawling, as they may feed on fish shoals very close to boats.

They are one of twenty four species of cetacean that occur in Ireland and are subject to strict protection under national and international legislation. Minister Deenihan said "I am concerned by any killing of these species, even where accidental. A meeting has been agreed between my officials and the Department of Agriculture, Food and the Marine to examine what further actions may be taken to minimise the risks to dolphins". Minister Coveney shared the concerns of Minister Deenihan and acknowledged "In addition to our own boats, many other European fleets operate in Irish waters, an area that is intensely fished. On the basis of these examinations, it is not possible to determine which of these fleets might have been involved in this incident. The results of these post mortems certainly remind us of the need to further our efforts to reduce incidental by-catch to the lowest possible level across all EU and third country fleets fishing in waters around Ireland".

#MarineWildlife - The Irish Examiner reports on the extraordinary story of a bottlenose dolphin who turned to a group of divers for help to free it from a fishing line.

The video above captures the touching scene when the cetacean approached the divers as they filmed a group of manta rays in the Pacific waters near Kona in Hawaii.

As the footage shows, the dolphin positioned itself in such as way as to allow diver Keller Laros to cut the fishing tackle that was tangled tightly around its midsection and remove the hook from its left pectoral fin.

After the dolphin took to the surface for a quick breather, the divers were able to free it from the line and allow it to swim away unharmed.

#marinescience – Scientists from GMIT's Marine and Freshwater Research Centre will depart Galway today on board the RV Celtic Explorer to carry out the fourth dedicated survey of cetaceans on the continental shelf edge. The trip will determine if a distinct population or 'eco-type' of bottlenose dolphin exists in offshore waters, as suggested by DNA analysis, photo-identification and behavioural traits observed in previous surveys.

'Cetaceans on the Frontier,' an annual research cruise since 2008, lead jointly by Galway-Mayo Institute of Technology (GMIT) and the Irish Whale and Dolphin Group (IWDG) records the number and distribution of whales, dolphins and porpoises along the continental shelf edge. The region is an important habitat for cetaceans because of the rich food resources available from increased productivity caused by upwelling when nutrients are brought to the surface from the depths.

This project aims to identify particular areas of importance for cetaceans as well as other species such as seabirds, with this survey focusing in particular on the bottlenose dolphin.

GMIT Marine Scientist and lecturer Dr Joanne O'Brien, says: "While many people are familiar with coastal bottlenose dolphins that are resident in the Shannon Estuary, or those which occasionally venture into bays and harbours during summer months, little is known about their offshore counterparts."

Mr Conor Ryan, the chief scientist on this survey, and member of the Irish Whale and Dolphin Group, says, "The bottlenose dolphin is required to have strict protection under the EU Habitats Directive but this is difficult to achieve for animals living offshore as we know little about their ecology, movements and the threats that they may face."

"As in 2012, we will take skin samples from these dolphins by deploying a small boat from the Celtic Explorer using a biopsy darting system to collect skin samples for DNA analysis, under licence from the National Parks and Wildlife Service. We will photograph their uniquely marked dorsal fins and catalogue individuals' movements. We also hope to characterise their preferred habitat type, e.g. their preferred depth and distance from the shelf edge."

Cetaceans on the Frontier is an inter-disciplinary research cruise, and scientists specialising in seabird biology, plankton and micro-plastics will also be collecting data in order to determine how different species are interacting with their environment and with each other. Last year the bird team recorded a rare black-browed albatross, tens of thousands of kilometres from its native Southern Ocean.

The micro-plastics research team, based in GMIT, aims to investigate how prolific plastic pollution is in the ocean, particularly in deep waters far from the sources of dumping. Zooplankton (including jellyfish such as the mauve stinger) will be collected in small nets and analysed for chemical tracers called stable isotopes which help ecologists to model food-webs including the diets and even movements of larger predators such as fish, birds and cetaceans.

Scientists from GMIT, IWDG, BirdWatch Ireland, Queens University Belfast, National Oceanographic Centre Southampton, University College Cork and University of La Rochelle will spend two weeks at sea, zig-zagging along the shelf edge from Co. Donegal to Co. Cork. The survey is funded through the Marine Institute's National Research Vessel Ship –Time Programme 2013 supported by the Marine Research Sub-programme of the National Development Plan 2007–2013.

#FUNGIE - He was the subject of rumours of his demise earlier this week - but the people of Dingle say their most famous resident, Fungie the dolphin, is alive and flipping.

A spokeswoman for Dingle Dolphin Boat Tours confirmed to The Daily Edge that Fungie is "definitely alive", and that no dolphin remains had washed up on the beach, as had been claimed on Twitter last Monday morning.

The Co Kerry fishing village is celebrating 30 years of the bottlenose dolphin's residency in its harbour. It's unclear exactly how old Fungie is, but it's presumed he was born in the mid 1970s.

#FUNGIE - A new video posted to YouTube celebrates 30 years of Fungie the dolphin in Dingle.

The male bottlenose dolphin appeared from out of nowhere in the Co Kerry fishing village in 1983 and soon made it his home, quickly becoming an integral part of the local community.

Since his arrival Fungie has made friends and warmed hearts with people both local and across the world, such as Dutch couple Jeannine Masset and Rudi Schamhart who have been meeting him for more than 20 years.

Meanwhile, locals hope that new measures for harbour users proposed earlier this year won't bring an end to boat trips to meet Dingle's most famous resident.

#MARINE WILDLIFE - A hat-tip goes to WorldIrish for this video posted on Vimeo by Monty Cantson capturing the moment when a playful dolphin paid a visit to a group of divers in Bones Bay at Doolin, Co Clare recently.

According to Lahinch Surf Experience, the bottlenose dolphin goes by the name of Dusty, after the singer Dusty Springfield.

The female cetacean has been a fixture of the area for more than a decade, and while apparently less friendly than Dingle's famous Fungie - she doesn't like to be touched - she seems happy to swim beside swimmers and divers, and loves to play with anything you might have in the water with you!

#MARINE WILDLIFE - The body of a porpoise washed up on a beach near Dundalk recently is believed to be one of two 'dolphins' rescued from the area just days before.

The Dundalk Democrat reports that the porpoise carcass was discovered by Blackrock Tidy Towns supervisor Pat Rafferty while on a litter patrol of the beach on Tuesday 3 June.

“It must have beached on Monday night sometime, as we would have seen it the day before," he said. "Unfortunately it seems that gulls had got to it.”

Rafferty added: "“Maybe if it had beached during the day we would have been able to rescue it.”

It's thought that the porpoise is one of the two 'dolphins' that were rescued from the shallows by local people and the DunDalk Sub Aqua Team during the Blackrock Raft Race on 25 June.

Harbour porpoises - one of the most common forms of marine wildlife in Ireland - are very similar in apperance to dolphins but have a more triangular dorsal fin and lack the dolphin's beak-like snout.

#IRISH HARBOURS - "Draconian" new charges for harbour users could bring an end to boat trips to see Dingle's most famous resident, according to The Irish Times.

Fungie the dolphin has been a mainstay of Dingle harbour for almost 30 years, but boat trips to visit him could cease to operate "with immediate effect" if charges of up to €9,000 are imposed "in advance" of the season.

Currently operators in the Dingle Boatmen's Association pay around €2,500 to use the harbour at the end of each season.

Association chairman Jimmy Flannery called on anyone working in tourism in Ireland to make submissions to the public consultation before the deadline next Friday 20 April.

As previously reported on Afloat.ie, yacht owners are also up in arms over the new charges proposed by Marine Minister Simon Coveney that could see their rates hiked by an incredible 800 per cent.

And the news comes not long after fellow Kerry harbour users protested proposed new bylaws to regulate their activities and impose new charges.

#MARINE WILDLIFE - Fears are growing of an illegal cull of marine wildlife after a seal and dolphin were discovered dead on a Waterford beach - just hours after two seals were found dying from bullet wounds in the same location.

TheJournal.ie reports that the wounds on the two animals found on Tramore Beach on Thursday are also believed to be from gunshot.

Two grey seals were euthanised the previous evening after they were discovered gravely injured with "horrific" wounds on the same beach.

A spokesperson for the Irish Seal Sanctuacy (ISS) has called for a post-mortem of the animals to determine the exact cause of death - but pointed the finger at an illegal cull allegedly carried out by local fishermen.

"We’re not against a properly regulated cull," said the ISS's Johnny Woodlock, "but it’s the guy who goes out with a shotgun and takes potshots, that’s what we’re against.”

#MARINE WILDLIFE - The first recorded sighting of a dolphin in an Irish lake has been reported by the Irish Whale and Dolphin Group (IWDG), according to The Irish Times.

The dolphin was spotted in Lough Hyne, a saltwater lake near Baltimore in Co Cork by Skibbereen-based kayaking instructor Jim Kennedy, who filmed it over a number of days.

"To the best of my knowledge, and I’m open to correction, this is the first validated record of a cetacean using an Irish lake," said the IWDG's Pádraig Whooley.

Though there have been no further sightings since then, there is nothing to indicate that the dolphin has yet left the lough for the open sea.

As previously reported on Afloat.ie, Lough Hyne was also recently visited by a 13-metre fin whale that was sadly found beached in stormy conditions on the Sligo coast this week.

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.
