The Irish Whale and Dolphin Group (IWDG) is bringing stories from the Celtic Mist’s historic marine wildlife survey voyage around Iceland to libraries and other venues nationwide.

Already the IWDG has visited 10 venues across eight counties in its ‘On the Trail of the Whale’ tour, which continues tonight (Tuesday 19 February) at 7pm in Killarney Library.

In May last year a crew of marine scientists and enthusiasts set sail on the IWDG’s research yacht for a weeks-long return passage to the edge of the Arctic Circle in search of humpback whales, building “strong links with Iceland and its people” along the way.

Last month, IWDG members began sharing their experiences from the rewarding mission in images, stories and video of the voyage to audiences in libraries and other venues across the island of Ireland — beginning on 14 January at DLR LexIcon and since visiting Galway, Tralee, Monaghan town and Arklow, as well as Bangor and Warrenpoint in Northern Ireland and Dublin’s Poolbeg Yacht Club.

“Through the tour, we want to encourage people to get involved,” IWDG’s chief science officer Dr Simon Berrow told the Irish Examiner. “If even one person at every event we do gets interested [in marine life] and gets motivated, that’s fantastic.”

The Irish Examiner has much more on the story HERE.

#MarineWildlife - Galway residents have a great opportunity to see a wild dolphin close to the city centre with the return of regular visitor to the Nimmo’s Pier area this week.

Nicknamed Nimmo, the solitary bottlenose dolphin was first sighted in the city in April 2015 and since then has become an annual fixture, appearing and staying longer each time.

The Irish Whale and Dolphin Group (IWDG) suggests this is a sign that the area around Galway city is now a “more important core feeding habitat for Nimmo”.

In other news, the IWDG’s research vessel Celtic Mist will embark on a series of week-long surveys this summer in search of humpback whales.

IWDG members are invited to join any of the nine legs, the first of which sets sail from 9-15 June (weather permitting) between Cork and Dingle/Fenit.

For details on how to book a place on any of these voyages and for further information, contact [email protected].

#MarineWildlife - Naval Service personnel on patrol with the LÉ Samuel Beckett encountered the carcass of a large whale some 50 nautical miles south-east of Ballycotton Lighthouse in the days after Christmas.

The “mystery whale” is neither a sighting (which only counts or living cetaceans) nor a stranding. But as the Irish Whale and Dolphin Group (IWDG) says, the encounter “serves to remind us that the animals that wash up on our shoreline may represent only a small percentage of the total number of cetaceans that expire at sea of presumably natural causes.”

IWDG sightings officer Pádraig Whooley said the location of these whale remains was “interesting as this area of the Celtic Sea has produced the most consistent large-whale sightings in recent months, with fairly regular sightings of fin whales from land-based sites between Ram Head, Ardmore extending east towards the Hook Head lighthouse.”

A dreary, stormy day in Dublin city centre was brightened with the appearance of a common dolphin swimming up the River Liffey as far as the Loopline Bridge.

The Irish Whale and Dolphin Group (IWDG) says it got its first reports early this morning (Wednesday 28 November) from the Jeanie Johnston, whose John O’Neill shot this video of the solo cetacean swimming loops in the river.

It was spotted swimming strongly as far west as Liberty Hall around lunchtime before heading back east and towards Dublin Bay.

Dolphins are known to develop kidney and skin problems on prolonged exposure to freshwater environments such as rivers.

However, the IWDG moved to assuage public concerns over this particular animal — saying that if it was swimming as strongly as sightings suggested, it would be more than able to swim back to sea.

It’s suggested that this short-beaked visitor may be one of a pod of some 20 dolphins known to be feeding off the East Coast this month.

#MarineWildlife - Video posted on social media over the weekend of two killer whales spotted off the Co Dublin coast has gone viral.

Trawlerman James Mac Cluskey used his phone to record a few seconds’ glimpse of the pair of male orcas, which came close to his boat some 8km off Rockabill on Saturday afternoon (17 November).

According to the Irish Whale and Dolphin Group (IWDG), it’s the second sighting of the largest species in the dolphin family off the East Coast in recent weeks, with another fisherman reporting an encounter some 22km off Skerries on 30 October.

And it’s believed the duo may be part of the Scottish West Coast Community Group, a unique orca pod long under threat of extinction owning to not having produced any calves for years.

Earlier this year, whales from this group were identified feeding off the Blasket Islands in Co Kerry, showing just how far their range extends.

#MarineWildlife - The Irish Whale and Dolphin Group’s (IWDG) datasets for cetacean sightings and strandings around the Irish coast are now back online after previous versions were corrupted in a cyber attack.

The launch coincided with the hosting in Kilkenny last week of the 25th meeting of the Global Biodiversity Information Facility (GBIF), an international network aimed at providing open access to data about life on Earth, marine wildlife included.

Twelve months of sighting and stranding data — including the recent ‘unusual mortality event’ of Cuvier’s beaked whales — can now be accessed, searchable by species, recorder, date and location, and all sightings are mappable.

Longer-term data is also available on request, for example for undergrad or postgraduate student projects.

All information in these datasets is provided by the IWDG’s loose network of volunteers around the island of Ireland, and is hailed by the group’s chief Dr Simon Berrow as “an excellent example of what can be achieved through citizen science.”

Dr Berrow adds: “Our recording schemes receive very little funding support. The sighting scheme gets no funding and currently the stranding scheme receives grant support of €10,000 from the NPWS, but it is not guaranteed and depends on other NPWS funding obligations.

“IWDG are committed to maintaining these recording schemes in the long term, as its only with time that we can identify trends; whether they are new threats to whale and dolphin populations or changing distributions driven by climate change and other large scale events.”

Both recording schemes have been run and supported by Pádraig Whooley and Mick O'Connell on behalf of the IWDG for over 20 years, and Dr Berrow says the information collected comprises “some of the most robust data in Europe to address key environmental issues and meet legal obligations.

“None of this would be possible without the IWDG members and non-members who go to great lengths to report strandings and sightings and take our calls to head out to the beaches and headlands all around Ireland to collect another data point. To them we offer our respect and thanks.”

Among the more recent sightings you’re likely to find is Boomerang, the humpback whale with the distinctive dorsal fin who’s made Ireland a regular stop since 2001.

He was spotted off the Clare and Kerry coast last month, as the Irish Mirror reports — and his return is a good omen for the quality of the ocean around Ireland, Dr Berrow suggests.

#MarineWildlife - The Department of Foreign Affairs will assist with an investigation into the extraordinary numbers of Cuvier’s beaked whale deaths in Irish waters over recent weeks.

Tánaiste and Foreign Affairs Minister Simon Coveney has “instructed his department, in consultation with the National Parks and Wildlife Service, to initiate discussions regarding these about large number of stranded Cuvier's beaked whales with the UK authorities,” according to the Irish Whale and Dolphin Group.

As previously reported on Afloat.ie, the IWDG had expressed concern over the large numbers of dead beaked whales washed up on Ireland’s North West coast last month.

The total of whale strandings since the beginning of August has now risen to 58 across Ireland and Scotland, many of them Cuvier’s or True’s beaked whales, as BBC News reports.

#MarineWildlife - The Papal visit brought numbers down for 2018’s Whale Watch Ireland last Saturday (25 August).

But some 950 wildlife enthusiasts still came out to 19 sites around the island of Ireland for the chance to spot some of the many whales, dolphins, porpoise and other wildlife in our waters.

Most sites reported a reduction in numbers, with only three seeing a modest increase. But it’s expected that next year’s turnout will be back to it regular size, coinciding as ever with events for Heritage Week.

Sightings were also lower this year — on average a 43% reduction on 2017’s records — with only three cetacean species spotted, namely harbour porpoise (50), common dolphins (40) and minke whales (5).

The success or otherwise of event is generally determined by the prevailing weather on the day, and thankfully most sites were treated to calm seas and clear skies which resulted in cetacean sightings at three-quarters of the sites covered at this year’s event.

Other species noted include grey seals, a basking shark and a sunfish.

Despite the lower attendance and sighting rates, the Irish Whale and Dolphin Group says it is “very pleased” with this year’s results.

“And we hope that among those who attended, there will be some new members for IWDG and dedicated whale watchers who are willing to volunteer some of their time and energy in furthering our understanding of the whales and dolphins that live in Irish coastal waters.”

The IWDG reports that usual there was a mix of both Irish and overseas visitors to the watches, and for many attending this was their first encounter with a cetacean in the wild in Irish waters.

#MarineWildlife - The Irish Whale and Dolphin Group (IWDG) has expressed concern in the wake of at least 16 Cuvier’s beaked whales washing up on the Irish coast this month.

Following the discovery of five beaked whales in a single day at the start of August, the IWDG says a minimum of 16 — a new Irish record — were recorded along the North West coast from Galway to Donegal between 3 and 22 August.

“During the same period, at least 13 were found in Scotland and two in Iceland,” said IWDG strandings officer Mick O’Connell.

“Previous studies have suggested that only a small number of dead animals actually get washed ashore and recorded, so the number of dead animals may be significantly higher.”

While no cause of death has been established, due to the poor condition of the carcasses, it appears that the animals all died around the same time, which “makes causes such as disease, plastic ingestion etc seem unlikely as these would tend to be spread out over a longer time period and perhaps geographical range,” O’Connell said.

“The behaviour and distribution of this species makes large-scale fisheries interaction also seem unlikely.”

Sonar use has been suspected as a cause in previous similar strandings. “Mass strandings of beaked whales coincidental with naval exercises have been recorded in Greece, the Canaries and the Bahamas,” O’Connell said.

According to TheJournal.ie, the Royal Navy denies its use of sonar in training exercises causes any harm to marine wildlife.

The Naval Service in Ireland does not use sonar on its vessels.

In more positive marine mammal news, Nuala Moore writes for Independent.ie about her experiences swimming in Dingle harbour with its longtime resident dolphin Fungie.

The open sea swimming enthusiast made headlines earlier this year for becoming the first Irish woman to swim off Cape Horn.

But in Dingle, she’s just another acquaintance for Fungie in his daily adventures.

#MarineWildlife - Ireland’s annual whale watch day takes place next Saturday 25 August — and the Irish Whale and Dolphin Group invites the public to join its land-based whale watches around the island of Ireland.

From 2pm to 5pm next Saturday, the IWDG’s volunteers will be raising awareness of the 25 species of cetaceans — porpoises, dolphins and whales — recorded to date in all Irish waters, and giving the public a great opportunity to look for and observe some of these wonderful marine mammals in their natural environment.

Whale Watch Ireland also provides IWDG researchers with a unique snapshot of whale and dolphin activity around the Irish coast on the day.

This annual, all-island citizen science event, organised by the IWDG in association with Inis the Energy of the Sea, is free and open to all as part of Heritage Week, co-ordinated by The Heritage Council.

All watches are land-based and will be led by experienced IWDG researchers and whale watchers, who will show you how to observe and identify some of the more commonly recorded cetacean species in Irish waters and who will be available to discuss the conservation work of the IWDG.

To make the most of the day, bring binoculars or a spotting scope, and dress appropriately for outdoor weather conditions. There are no boat trips involved and there is no guarantee that you will see whales or dolphins at your chosen site.

But at last year’s event, whales or dolphins were recorded at three-quarters of sites around the Irish coast.

The full list of watching locations, with watch leader contacts, is as follows:

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.
