A rare sight was caught on camera this past week with the birth of a bottlenose dolphin in Glandore Harbour.

Following reports on Monday (15 April) to the Irish Whale and Dolphin Group (IWDG) of a large gathering near Mizen Head of some 25 bottlenoses — a dolphin species not frequently seen off West Cork — a second similar-sized group was spotted two days later some 60km to the east at Glandore.

Local IWDG member Heather Mahmood flew her drone over the Glandore pod to capture some footage and images, and upon reviewing the results with her daughter Ruá on Thursday evening, the pair were surprised to discover what appeared to be a dolphin giving birth.

After sending the footage and images to the IWDG, sightings officer Pádraig Whooley came to the same conclusion.

“[It appeared] that it was indeed a female either giving birth or in the process of, as the appendage [seen protruding from the dolphin] looked very similar to a tiny, floppy tail fluke,” Whooley said.

“It is known that to maximise the chance of a successful birth, which can be a long process for all mammal species, cetacean calves are born tail-first. This is an adaptation to living in an aquatic environment, as it gives the new born the maximum breathing time inside the birth canal — that first breath being the critical one.”

Whooley referred to the IWDG’s resident experts on bottlenose dolphins, Simon Berrow and Mags Daly of the Shannon Dolphin Project, who were just as astounded.

“Neither of them have ever witnessed the birth of a bottlenose dolphin, despite being involved in monitoring the resident Shannon population now for over 30 years,” Whooley said.

“In fairness, how could they have, as this behaviour could really only be detected from an aerial perspective, which we now have at our disposal.”

The IWDG shared their findings with Cromarty-based Dr Barbara J Chaney, who studies the Scottish bottlenose population that overlaps with our own, “and her thoughts mirrored ours, that this footage was unique, both in a British and Irish context, as this event has never before been seen, let alone recorded,” Whooley added.

The ESB has announced the completion of an industry-endorsed marine mammal observer (MMO) training programme to support those in the early stages of their careers in the marine environmental sector.

An additional key aim was to fill a gap in the Irish offshore wind industry’s local supply chain due to a lack of locally based MMOs on the island of Ireland.

Launched in 2023, the programme was open to recent graduates, final-year undergraduates and postgraduate students who studied or worked in the area of marine science or related disciplines.

The five successful applicants took part in industry-approved training courses including basic offshore safety induction and emergency training (BOSIET), the UK’s Joint Nature Conservation Committee (JNCC) MMO training certifications with additional Irish Guideline modules, and Offshore Energies UK (OEUK) approved medical and fit-to-train certifications.

Participants took part in MMO training provided by the Irish Whale and Dolphin Group (IWDG) and spent two nights onboard the research vessel Celtic Mist at Kilrush, Co Clare, followed by a half-day at sea.

All participants were also provided with one-year complimentary membership of the IWDG, the Marine Mammal Observer Association (MMOA) and the Institute of Marine Engineering, Science and Technology (IMarEST) with professional mentoring support and access to the Career Development Pathway.

Speaking on the completion of the programme, ESB’s Offshore Ecology Team said the programme represents a significant milestone.

“As of 2024, Ireland now has five newly trained and much-needed MMOs as a result of this initiative. Through this programme, ESB has demonstrated its commitment to supporting the marine mammal bbserver role in Ireland, nurturing local talent which will be essential in the delivery of ESB's Net Zero targets by 2040,” the team said.

“Our funding has facilitated opportunities to enhance skilled work readiness and has strengthened local talent in collaborating with local organisations such as the Irish Whale and Dolphin Group amid Ireland’s renewable energy expansion. At the heart of this Programme is the inspiration and support of young professionals seeking fulfilling careers in marine ecology and sustainable energy.”

Amy O’Reilly, one of the newly trained MMOs, shared her insights into the experience: “The ESB MMO training programme has been a wonderful opportunity and unforgettable experience for me. When I first applied, I had a history of volunteering with marine wildlife charities and was in the middle of a nine-month internship with the cetacean charity Manx Whale and Dolphin Watch. ESB recognised my passion and drive towards building a career in the marine science field.

“Some of my highlights from the programme included sleeping on board the Celtic Mist, undergoing training by the very wise and seasoned MMO Mr Patrick Lyne and, of course, escaping from a helicopter underwater in the BOSIET training.

“I am delighted to say that with this training as a foundation, I have been able to get my first MMO role with IWDG consulting, working on a short project in Dublin Port.”

Qualified MMOs are environmental professionals who specialise in monitoring marine megafauna species and ensuring the implementation of mitigation requirements during various industry operations, and they will be key components in the delivery of offshore wind projects over the coming decade.

Ireland has a unique capability given its prime location to take advantage of the potential of offshore wind, the ESB says.

ESB has announced plans to fund a marine mammal observer (MMO) training programme which is open to graduates, final-year undergraduates and postgraduate students who are studying or working in the area of marine science or related disciplines.

The aim of the programme is to assist in developing marine ecology education and skills to support successful applicants at the early stages of their careers in the marine environmental profession.

ESB will award up to five places on the MMO training programme. All applicants must be available to participate in person for training at Kilrush, Co Clare on 4-5 November. Application forms can be requested from ESB via [email protected]. The deadline for application submissions is next Thursday 12 October.

Industry-approved training courses and medicals will be funded to bring individuals up to the standard level of competency for offshore work. These courses include Basic Offshore Safety Induction and Emergency Training (BOSIET), the UK’s Joint Nature Conservation Committee (JNCC) MMO training with Irish Guideline certifications, and Offshore Energies UK (OEUK) approved medical and Fit-to-Train certifications.

The training programme is being endorsed by the Marine Mammal Observer Association, which will offer one-year complimentary affiliate membership to successful candidates and provide further advice and mentoring support for pursuing a career as an MMO.

The programme is also being endorsed by the Institute of Marine Engineering, Science and Technology (IMarEST), which will offer one-year complimentary associate membership and one-year access to its career development pathway.

The MMO training will be provided by the Irish Whale and Dolphin Group (IWDG) and will include classroom-based training, two nights’ accommodation and a half-day at-sea experience onboard the research vessel Celtic Mist. The IWDG will also offer one-year complimentary membership to programme participants.

The ESB’s Offshore Ecology Team said: “As we continue with our drive at ESB to deliver offshore wind projects as part of our Net Zero by 2040 strategy, we are committed to promoting the MMO role in Ireland, and increasing the number of qualified and experienced local professionals that will play such an important role in the future of the industry.

“Training programmes such as this will not only add to the creation of employment opportunities but will also contribute positively to help protect species as Ireland develops offshore renewable wind energy.”

Simon Berrow, chief executive of the IWDG said: “Over the last 30 years the IWDG has been at the forefront of whale and dolphin conservation in Irish waters. Now, with increasing pressures on our seas, especially the coastal zone, there is more demand than ever for trained and experienced marine mammal mitigation experts.

“The IWDG is delighted to be working in collaboration with the ESB to provide pathways to joining the offshore industry in an environmental capacity, to ensure the continued safeguarding of marine mammals in Irish waters.”

Ashleigh Kitchiner, chair of the Marine Mammal Observer Association said: “MMOA believes that investing in developing emerging professionals is vital for the growth and sustainability of our industry. We are confident that this MMO Training Programme coupled with our endorsement and support will contribute to the success of each candidate.”

Gwynne Lewis, chief executive of IMarEST said: “Nurturing the next generation of marine professionals and ensuring their access to the resources, networks and educational opportunities essential for their development is central to our work. It is vital that we inspire, encourage and support young people to want to have a rewarding career as marine professionals.”

Qualified MMOs are environmental professionals who specialise in monitoring marine megafauna species and ensure the implementation of mitigation requirements during various industry operations. Such roles will play an important part in the delivery of offshore wind projects over the coming decade.

The Shannon Estuary’s resident population of bottlenose dolphins could be under threat from plans to transform the area into a green energy hub, a conservation group fears.

Plans revealed last month in the final report of the Shannon Estuary Economic Taskforce envisage the delivery of up to 30GW of power from offshore wind energy projects in the estuary by the year 2015.

But according to the Irish Examiner, the news has prompted concern from the Irish Whale and Dolphin Group (IWDG) for the status of the estuary’s protected and unique dolphins.

Marine wildlife such as dolphins are especially sensitive to noise from human activity, such as that which would be involved in the construction and maintenance of offshore wind farms and other green energy infrastructure.

“We are lucky to have these dolphins, they are unique and it would be a tragedy if they were not there anymore in 30 years,” said the IWDG’s Dr Simon Berrow — who added that he has yet to receive a response after reaching out to Taoiseach Leo Varadkar, Environment Minister Eamon Ryan and the taskforce.

A fin whale found stranded near Ballinskelligs, Co Kerry at the weekend will not be subject to a post-mortem examination to determine its cause of death, the Irish Whale and Dolphin Group (IWDG) has said.

The whale was visited by IWDG strandings officer Stephanie Levesque under the Deep Diving and Rare species Investigation Programme (DDRIP).

DDRIP was initiated by the IWDG in 2022 in response to a well-documented increase in recent years in cetacean stranding records reported through the IWDG’s stranding scheme.

“Unfortunately this individual was too decomposed for a full post-mortem,” the IWDG said. “Stephanie collected a number of samples useful for biological studies but [was] not able to establish cause of death.

The whale was a male measuring 19 metres in length which would have made it not fully grown. Samples of skin, blubber and baleen were taken, the group added.

As for next steps, the IWDG says that Kerry County Council is intending to let the remains rest in situ as it is on private land in a secluded area.

The Nautical Institute is hosting a free webinar: Minimising Whale Strikes, Enhancing Mariners' Awareness of these Majestic Creatures which is to be held on Wednesday 15th February (9.00-10.30 GMT).

Seafarers have a love of the oceans and take great joy from sharing the environment with marine life. In fact mariners and shipping companies are often considered protectors of the oceans as can be seen by the huge efforts being made by individuals and the industry as a whole to prevent pollution at sea.

Sadly, despite our best efforts, strikes on marine mammals such as whales and dolphins continue to have an impact.

This Nautical Institute webinar seeks to explore the risk of whale strikes, help seafarers understand the nature of these mammals and identify how, with a bit of awareness, we can avoid striking them inadvertently and reduce harm against these magnificent animals which share our lives.

The following webinar Speakers are: MSC Vice President of Sustainability, MSC Mediterranean Shipping, Stefania Lallai; Dr Simon Berrow, Chief Science Officer and CEO of Irish Whale and Dolphin Group (IWDG); Sibéal Regan, IWDG Education and Outreach Officer; and National Geographic Explorer, Dr Rui Prieto, to discover the steps we can take to avoid whale strikes.

The free webinar from The Nautical Institute will be interactive, inviting feedback and questions from attendees and will provide a certificate of participation to all those who attend.

The Irish Whale and Dolphin Group (IWDG) has combed through years of accumulated images to make a start on its new photo identification catalogue for fin whales in Irish waters.

And the group is calling on anyone with good-resolution images of the often elusive cetaceans to submit them to the catalogue for appraisal and potential matching.

“It only takes one strong image to reveal an animal’s identity,” IWDG sighting officer Pádraig Whooley says, “and in time this citizen science resource should begin to tell us more about the life histories of the wider cohort that arrive annually along the Irish South Coast most years during May.”

Whooley explains that recording of fin whales in Ireland — historically the more dominant of Ireland’s two large baleen whale species — had taken a backseat to that of the larger, more easily photographed humpback whales which began arriving in greater numbers a decade ago.

Another reason for this shift in emphasis, Whooley says, was the “international significance” of Ireland’s rising numbers of a marine wildlife species, in humpbacks, that has been more susceptible to commercial exploitation.

In recent weeks, however, Whooley says the time was right to revisit the IWDG’s trove of fin whale images which he and Andrew Malcolm have “whittled them down” to a starting set of “53 well-marked individuals, several of whom have been recorded over multiple years”.

“As with the humpback catalogue, these animals have been allocated unique references with associated sightings histories and are stored on a Google drive for ease of matching new images and sharing with colleagues both at home and overseas,” Whooley adds.

It’s hoped to grow this collection with contributions to the public to [email protected]. The IWDG asks that submissions be of at least medium to high resolution, sharp and shot within 100 metres of the focal animal. Especially desired are photos that show “a well-marked dorsal fin or linear scars, blemishes, signs of ship-strike injuries, entanglement marks etc” that will ease identification.

“Given the nature of fin whales and what appears to be declining numbers in Irish waters, this catalogue will no doubt throw up many challenges in the years ahead, but we’re confident there will also be some fascinating discoveries that will help inform future management plans for the largest whale in our coastal waters,” Whooley says.

“As with the humpbacks, one of the first questions we’ll be hoping to answer is, where are their breeding grounds? It’s remarkable that thus far this vital piece of ecological information has eluded whale researchers… perhaps the Irish fin whale catalogue will help solve this mystery?”

An abridged version of the fin whale catalogue will be made available on the IWDG website for citizen scientists to try to match any fin whales they’re fortunate to encounter.

Despite lower attendance and a reduced sighting rate, the Irish Whale and Dolphin Group (IWDG) says it is “delighted” with the return of its All-Ireland Whale Watch Day last month.

Held on Saturday 20 August during Heritage Week and for the first time since 2019, on account of the COVID pandemic, this year’s event saw an overall decline in attendance (-38% on 2019) and fewer cetacean sightings (33% of sites compared to 58% in 2019).

IWDG sightings officer Pádraig Whooley, who organised the event, suggested that a confluence of factors — from windy conditions on the day to the legacy of the pandemic and even holidays abroad — may have affected the turnout.

In addition, the poor sea state at many watch sites would have affected the sighting rate, with the best results at Clogherhead in Co Louth (two dolphin species and four harbour porpoises) and Howth Head in north Co Dublin (10 harbour porpoises). No whales were recorded at any of the 18 sites.

But some 530 marine wildlife enthusiasts made a day of it around the Irish coast, and Whooley is optimistic about the future of the initiative.

“We hope that among those who attended, there will be some new members 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,” Whooley said.

“Our challenge, post-pandemic, is to find new and innovative ways to rebuild this important natural history event and so we may explore the potential for moving it to May in 2023 to coincide with Biodiversity 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.
