The carcass of a juvenile humpback whale washed ashore in West Cork is only the ninth such stranding of the species in Ireland, according to the Irish Whale and Dolphin Group (IWDG).

Sightings officer Pádraig Whooley confirmed from images of the marine wildlife specimen captured in Roaringwater Bay yesterday (Wednesday 24 February) that it was a juvenile male not previously recorded in Irish waters.

Such young whales are not unexpected close to our shores at this time of year, when adults of breeding age are either en route to or already at lower-latitude breeding sites such as Cabo Verde off West Africa.

“This is something that some young humpbacks can opt out of, as it’s a long track south to places like the Cabo Verde and with no hope of successfully breeding there is nothing much in it for them,” Whooley explains.

“So a cohort of young, independent humpbacks seem content to over winter at higher latitudes, where there is, or should be, plenty of food for them.”

In this case, however, Whooley says: “The images we’ve received so far suggest it is in rather thin condition and so it may not have fed for some time.

“There are no obvious signs of rope marks or net damage that may suggest entanglement in fishing gear, something that slow-swimming humpbacks that remain inshore are prone to. And there are no large traumas to suggest ship-strike. So as is so often the case, the circumstances underpinning this stranding are unclear.

“IWDG hope in the coming days to visit the site to take detailed measurements and get skin and blubber samples which can be used for genetics, contaminants and stable isotope analyses.”

Whooley adds that the IWDG is in liaison with the National Parks and Wildlife Service (NPWS) regarding examination of the carcass and its disposal, but suggests that because of its remote location “there is no strong case for removal”.

The Irish Whale and Dolphin Group (IWDG) has announced a new educational resource for young and aspiring marine science experts.

Ireland’s Blubber Book: Flukes Junior Vol 1 is a comprehensive workbook on cetaceans – the marine wildlife family comprising whales, dolphins and porpoise – found in Irish waters for primary school children aged between 9-12.

The new resource was created to support support the aims of the National Strategy on Education for Sustainable Development by IWDG education and outreach officer Sibéal Regan and illustrated by the talented John Joyce and Jim Wilson.⁠

“We believe that the first step in becoming an ocean literate and informed society, starts with our youngest citizens,” the IWDG says in its introduction to the resource.

It adds that the workbook “will motivate and empower them throughout their lives to become informed active citizens, who take action for a more sustainable blue future”.

Teachers can use Ireland’s Blubber Book in a classroom setting, by going through the content and worksheets themselves.

But the IWDG is also offering to facilitate virtual workshops “making the experience even more interactive and engaging”.

Interested schools can contact Sibéal Regan at [email protected] to enquire about using this new book in their classroom.

It will also be available from the IWDG shop and will have its official launch online on the IWDG Facebook page next Thursday 28 January at 11am.

The Irish Whale and Dolphin Group’s annual conference is moving online — and broadcasting live from West Clare next Saturday 12 December.

Whale Tales is the annual meeting of the IWDG, where members and people interested in whales, dolphins and porpoises in Ireland are invited to join in a shared appreciation and admiration of these charismatic examples of marine wildlife.

This year, due to coronavirus restrictions. Whale Tales 2020 will be a virtual meeting, with a panel of local speakers calling in from the IWDG head office in Kilrush as well as special guests from further afield.

Among them will be Joy Reidenberg, from the hit TV programme Inside Nature’s Giants, who will discuss the topic of large whale necropsies and what we can learn from them.

In the afternoon, Mags Daly of the Shannon Dolphin Project will tell tales of her favourite mammals and share some of her stories from the Shannon Estuary this summer.

Registration is free for all who want to join in, but donations are welcome to support the IWDG in its recording and conservation efforts.

The full programme of events, including details of how to book your virtual spot, can be found on the IWDG website HERE.

The first Irish and Scottish Humpback 'match' has been made from images taken on the Shetland Islands at the weekend and then matched to photographs of the same whale off Ireland in 2015 and seen again off Irish coastal waters as recently as June 2020.

In an exciting development for Irish marine wildlife fans, the Irish Whale and Dolphin Group (IWDG) confirmed on social media this morning (see below) that the Irish Humpback whale named #HBIRL38 was photographed on 7 November off Whalsay, Shetland. This whale has been recorded 16 times by the IWDG over four years since July 2015 and was last seen off West Cork on 2 June 2020.

“It’s better this way, rather than Fungie wash up dead on the shores of Dingle Bay, [that he] just disappear.”

That’s the message from the Irish Whale and Dolphin Group’s (IWDG) chief executive as nearly two weeks have passed since Dingle’s longtime resident dolphin was last seen in the Co Kerry village.

Writing on the IWDG website, Dr Simon Berrow reminisces about his own encounters with the friendly bottlenose since his own arrival in the West of Ireland in 1988.

And he believes that Fungie has been an inspiration some of the millions who have witnessed him over the years to pursue further interests in marine matters.

But Dr Berrow is also brutally honest about the region’s over-reliance on the marine wildlife singleton as a draw for visitors.

“Building an international tourism product on a single dolphin was never going to last,” he says. “It was unsustainable.”

The Irish Whale and Dolphin Group (IWDG) says it has recently documented evidence of a humpback whale scarred by entanglement in fishing gear in Irish waters.

Humpback IRL#HB43 was photographed in Dingle Bay on Sunday 11 October by IWDG member Nick Massett, who noted in his images some significant scarring on its tail fluke that was not present when the same whale was spotted off West Kerry two months prior.

The charity says this scarring is consistent with entanglement — and it’s believed, based on the marine wildlife giant’s known movements between August and this month, that the lesions were sustained off West Kerry.

Humpback whales regularly feed in Ireland’s inshore waters during the summer and autumn. But this activity also brings the whales into close proximity with active fisheries.

“It’s likely this animal got caught in the rising rope of a marker buoy to a string of lobster pots, or gill net,” Massett says.

Entanglement in fishing gear is an issue of emerging concern to the IWDG, which is working with Dr Charla Basran at the University of Iceland’s Husavik Research Centre to quantify the rate of entanglement of humpback whales in Irish waters.

Dr Basran recently published work showing that 24.8% of 379 individual humpback whales photographed in Iceland presented wrapping injuries and notches known to be indicative of entanglement.

Ireland shares a whale population with Iceland, and the IWDG says will be interesting to quantify the rate of these lesions on whales photographed in Ireland — and potentially reveal where along their journey to the North Atlantic from their southern breeding grounds they pick up their wounds.

The IWDG is planning a workshop on the issue supported by knife-maker Spyderco, which has provided knives customised for cutting ropes from live whales.

The Irish Whale and Dolphin Group has conformed the first validated sighting of a fin whale off Co Donegal.

Liz Morrow captured images of the solo large whale in Donegal Bay off Slieve League earlier this month, estimating it to be around 18 metres in length.

Fin whales are a common occurrence in Ireland’s South West and the Celtic Sea, but have never before been spotted in the inshore waters of the colder North West.

However, with the later sighting of a humpback whale breaching off Malin Beg, it could be a sign that larger marine wildlife are exploring new territory north of Sligo.

“Any large whales that simply look too large to be a minke or humpback and produce a powerful columnar ‘blow’ on surfacing, should be considered as likely candidates,” the IWDG suggests.

“They will often be accompanied by common dolphins who hunt the same sprat and herring shoals and they never lift their tails before diving.”

Suspected fin whales are best approached from the right side and photographed at the head and rostrum “which should reveal the diagnostic lower white right jaw”.

It has emerged that the deadly mass stranding of bottlenose whales in Donegal was preceded by two live strandings in the Faroe Islands two days prior.

And it’s led experts at the Irish Whale and Dolphin Group (IWDG) to suggest the marine wildlife incidents might be linked and “part of a much wider event”.

The group adds that images of two Northern bottlenose whales — of the same species that died in Donegal — were captured the next day in Scotland as far inshore as Greenock Harbour, on the Clyde west of Glasgow.

More recently, two of the deep water cetaceans have been seen in the North Sea off Norfolk, and two others were spotted at the Netherlands’ Eastern Scheldt.

“Clearly something is happening to this group of whales we know so little about,” the IWDG says, adding that the situation also “demonstrates the need for a response protocol” for similar strandings in Ireland.

One of the victims of a deadly mass stranding of bottlenose whales in Donegal last week has not reappeared, according to Highland Radio.

Seven of the marine mammals died in the biggest mass stranding of its kind on record in Ireland, as previously reported on Afloat.ie.

The eighth whale was refloated in the shallows when the tide came in, and hopes were that it would make to back to deeper waters on its own. However it was confirmed to have died the following morning, Thursdasy 20 August.

Local volunteers with the Irish Whale and Dolphin Group (IWDG) have appealed for the public to report any possible sightings, as they are keen to get samples which might reveal more details about the whale pod and its sudden demise.

Elsewhere, rare video has been captured of the humpback whale known as ‘Boomerang’ off West Cork, as RTÉ News reports.

The whale is the third humpback in the IWDG’s records. It was first identified in 2001 thanks to its unique dorsal fin, and has returned to feed in Irish waters regularly over the last two decades.

This story was updated on Monday 31 August to correct details about the refloated bottlenose whale, which was not presumed to have survived as the previous version stated.

The Army could be employed to euthanise beached whales and other marine wildlife that have no prospect of being refloated, the Irish Whale and Dolphin Group suggests in its draft protocol.

As the Irish Independent reports, the proposal is part of the charity’s push towards a more humane approach to whale strandings — a subject in focus since last week’s mass deaths of bottlenose whales in Co Donegal, the largest of its kind on record in Ireland.

Concerns were raised over crowds gathered on Rossnowlagh Beach last Wednesday (19 August) to take selfies or demand further rescue efforts, causing the animals additional distress in their final moments.

The IWDG’s chief Dr Simon Berrow said: “People are naturally curious and very well-meaning, but there was no possibility of refloating the whales, and we were trying to minimise their distress.”

Dr Berrow ruled out the use of drugs to euthanise stranded marine wildlife, but suggested that the Army could be trained for ‘humane shooting’ and called for inter-agency discussion of the matter.

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.
