O’Sullivan’s Marine have shared with us a photo of the surprise moment when a dolphin landed on the bow of one of their boats.

The sudden encounter was all the more startling as the marine mammal almost knocked a child out of the boat — but the youngster still managed to capture the cetacean on camera.

Elsewhere, BreakingNews.ie reports that a striped dolphin was found dead in a river near Lahinch despite the best efforts of local surfers after the animal live-stranded on the popular North Clare beach.

Dr Simon Berrow of the Irish Whale and Dolphin Group, who also joined the rescue effort, said: “We found a striped dolphin, quite a large animal, obviously in distress. We tried to push it out again [to sea] but it was very weak.”

The IWDG chief added: “The surfers did their best and we thank them for trying but sometimes a dolphin will live strand themselves … there’s very little you can do.”

Sixteen years after the Irish Whale and Dolphin Group’s (IWDG) first attempt to find the origins of Ireland’s humpback whales, a chance excursion on the latest expedition to Cape Verde has finally revealed the breeding grounds for these threatened marine wildlife visitors.

It was long suspected that the waters around the island chain off West Africa were the most likely breeding area for humpbacks that have been sighted nearly 1,000 times and photographed ever 100 times in Irish waters over the last two decades.

But that wasn’t confirmed until this April during a two-week expedition, when on a trip to a known breeding spot in Santa Monica off Boavista, IWDG chief Simon Berrow photographed two humpbacks that surfaced near his boat.

One of these whales was identified by the group’s international network of experts as an individual sighted by Nick Massett off Kerry four years ago. It was just the match they’d been searching for.

“What a fantastic outcome for the IWDG,” said Massett at the news. “It was born out of the belief that the Cape Verde islands was the breeding ground for the humpbacks we have documented here off Ireland. But it is down to the dogged persistence of the expedition teams that have returned there over the years to prove the theory.

“I am delighted for Simon Berrow that he finally got the definitive proof of this connection, and pleased to have played my part in documenting the animal here off Co Kerry.”

Also celebrating the achievement was IWDG sightings officer Pádraig Whooley, who had been beginning to doubt whether they had been looking in the right place all these years.

“We’ve finally found a really important missing piece of the jigsaw,” said Whooley, “but it’s a very large puzzle, which still has lots of missing pieces.”

The next steps for the IWDG are to determine how to use this information to enhance conservation for the endangered species, perhaps involving a greater level of co-operation between the Irish and Cape Verdean governments.

Meanwhile, the group will follow-up this find with another expedition to Cape Verde this coming September.

Sightings of an unusual looking bottlenose dolphin off the East Coast in recent weeks have turned out to be a Scottish scrapper named Spirtle.

Images of the dolphin seen off South Dublin and North Wicklow earlier this month showed what appeared to be heavy scarring and discolouration on its right flank.

That was enough for Dr Joanne O’Brien of the Irish Whale and Dolphin Group (IWDG) to identify the animal as the daughter of a dolphin well known in the Moray Firth.

Spirtle’s story is one of survival as almost three years ago to this day, she was found live stranded with significant injuries and suffering severe dehydration.

Since then she’s bounced right back from the brink of death, and it appears she’s now even at the lead of a group of bottlenose dolphins that’s made its way south along the Irish Sea beyond Dublin Bay.

A rare sighting of a different kind was made in West Cork this past week, where a charter boat operator witnessed what he believed was an attack on a pod of common dolphins by a killer whale.

David Edwards was 15 miles south of Galley Head last Tuesday (21 May) when he saw the orca chase after its fellow cetaceans for its lunch — and his images of the event have been confirmed by IWDG sightings officer Padraig Whooley.

A group of Ireland’s environmental NGOs are teaming up this spring for a rather unique education project lead by the Irish Whale and Dolphin Group. The exciting Floating Classroom initiative is combining ocean exploration with an educational schools programme which aims to raise awareness of Ireland’s marine biodiversity. Taking to the seas in the IWDG’s research vessel Celtic Mist, the team of marine biologists and ocean literacy experts will be making their way down Ireland’s south-east coast from Arklow to Cork, calling into coastal communities providing engaging workshops to schools along the way.

After an extensive refit during the winter in Grand Canal Docks, Dublin, the 56-foot ketch yacht will also be open to the public when docked at local marinas and harbours, giving the public an opportunity to see the workings of a dedicated whale and dolphin research vessel and how researchers live and work at sea.

Apart from raising awareness for Ireland’s rich marine wildlife, the team will be emphasising the importance of taking care of our seas and oceans. With challenges such as plastics pollution, climate change and biodiversity loss now frequently in the news, there is a pressing need for communities to work together to tackle environmental issues.

While pupils will be introduced to the wealth of marine and coastal wildlife on their doorstep, each school will be asked to come up with three ways in which they feel they can make a difference for their local blue environment.

The team of biologists will also be proposing ways in which the public can get involved, including citizen science projects that encourage people to report their sightings of whales, dolphins, seabirds and even shark eggs! Schools will be encouraged to get involved in other community-based initiatives too, such as beach cleans being run by organisations in their area.

Environmental NGOs involved in the Floating Classroom include the Irish Whale and Dolphin Group, Marine Dimensions, the Irish Wildlife Trust and the Irish Ocean Literacy Network. Funding for the Floating Classroom has been kindly received by the Irish Environmental Network through their Capacity Building Grant.

Whale watchers have captured spectacular aerial video of a group of humpback whales spotted “socialising” off West Cork.

The Irish Whale and Dolphin Group’s science officer Seán O’Callaghan filmed the remarkable scene last month just days after the first humpback whale sighing of the year was made in the same region, sailing out of Reen Pier.

“We had perfect sea conditions to search for cetaceans (whales, dolphins and porpoises) but our efforts to spot distant large whale blows were hampered by Saharan sand that caused a thick haze at sea,” the IWDG said.

“However, we did connect with up to six humpback whales feeding and socialising in offshore waters which allowed us to collect the first set of aerial images and video that will be used to estimate the length and body condition of these iconic giants.”

The video shows four of the humpback whales interacting with each other while common dolphins swim just ahead and among them.

And it marks the first significant contribution to WhaleTrack Ireland — the IWDG’s new drone-based citizen science project, supported by Ryanair, which aims to find out what these and other marine wildlife giants are doing within and beyond Irish waters.

#MarineWildlife - A team from the Irish Whale and Dolphin Group (IWDG) was on site at Streedagh Strand in Sligo yesterday (Thursday 4 April) to investigate the third sperm whale stranding in a matter of days along Ireland’s West Coast.

As reported yesterday on Afloat.ie, the discovery of a third such whale carcass made for an “increasingly unusual stranding pattern”.

While sperm whales are relatively abundant in Ireland’s deep ocean waters, they are rarely found above 300 metres — and male specimens are far more common than the female whale found in Sligo.

The IWDG confirmed that samples were taken from the 10.4m carcass, which showed “no obvious signs of ship collision [or] entanglement, nor was the whale emaciated”.

Examination of stomach contents found no plastic debris and few food remains.

“So as is so often the case with strandings, we know more about what didn’t kill the whale than what did kill it,” the IWDG stated — adding that it is liaising with Scottish colleges after a decomposed sperm whale was found on Uist in the Outer Hebrides, due north of Ireland, in recent days.

The group also notes that multiple warships and submarines are involved in Nato’s annual Joint Warrior exercise ongoing west of the Hebrides.

Sonar activity from military vessels has been suggested as a cause of whale strandings throughout Europe in recent years, including a major event across Scottish and Irish waters last year.

“However, these whales have been dead for one to two weeks so this can’t explain these strandings, unless some active equipment was tested offshore prior to the start of this exercise,” the IWDG says.

#MarineWildlife - A third sperm whale stranding on Ireland’s west coast within just a few days is now a cause for concern, the Irish Whale and Dolphin Group (IWDG) says.

Following the discovery of two sperm whale carcasses on the same day last week — in Donegal and west of the Aran Islands, the latter believed to have beached in Connemara — a third was found washed up on Streedagh beach in Sligo at the weekend.

Images of the latest stranding suggest it is an adult female, which the IWDG describes as “a little unusual” as “generally we get adult male sperm whales off the Irish coast”.

The close proximity of the strandings is also “now a concern”, though no cause of death has yet been determined, and plastic pollution is unlikely to be the culprit.

The IWDG added it “will explore some potential options regarding this increasingly unusual stranding pattern”.

Meanwhile, RTÉ News reports that the Galway council officials hope the sperm whale carcass washed ashore in Connemara will be taken out by high tides in the coming days.

#MarineWildlife - The UK’s Natural History Museum has made available for the first time a vast trove of whale and dolphin stranding records in British and Irish waters.

The data covers the years 1913 to 1989, filling in a significant gap before the Irish Whale and Dolphin Group’s stranding scheme began in 1991.

Over the years many entries were submitted by the coastguard, fishermen and members of the public — including a detailed record of a harbour porpoise found in Co Cork in 1913, the very first card in the data set.

PhD candidate Ellen Coombs is combing through the records to determine what picture “one of the longest systematic cetacean stranding data sets in the world” reveals for the status of cetacean species in our waters.

And already there have been some important finds, such as occasional records of deep-diving Cuvier’s beaked whales over the decades — not to mention a double stranding of narwhals in 1949.

The data also correlates with already known trends, such as the sharp decline in blue whale records with the expansion of commercial whaling in the early 20th century.

#MarineWildlife - The remains of two sperm whales have been spotted around Ireland in recent days.

The first was sighted in the Atlantic Ocean some 100km west of the Aran Islands on Monday (25 March) by an Air Corps airman.

Later that same day, samples were taken from a 43ft sperm whale carcass found washed ashore at Magheroarty in Co Donegal. Highland News says it it thought to have been dead for a number of weeks.

Sperm whales are the largest predator in Irish waters and are relatively abundant in deep ocean but are rarely found above 300 metres, according to the Irish Whale and Dolphin Group.

The IWDG adds that a recent study estimated there are 3.2 sperm whales per 1,000 square kilometres of Irish waters.

#MarineWildlife - Unusual weather for this time of year may be responsible for a recent spate of whale and dolphin strandings on the Cork coast in the past week.

The Irish Examiner reports that among the eight strandings were the carcass of a sperm whale on Long Strand in West Cork and a dolphin with fishing line around its beak in Schull.

However, the Irish Whale and Dolphin Group’s (IWDG) Mick O’Connell said that while the statistic was high within such a short timeframe, it was not necessarily a mystery.

“We normally get the same thing every year,” said the IWDG stranding officer. “It is usually more in the southwest and west, but this year, I suppose we have had more southeast winds, which probably explains it.”

O’Connell added that the strandings are “only a percentage of what is actually dead at sea” — and that post-mortems may “shed some light in their deaths”.

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.
