The Irish Whale and Dolphin Group (IWDG) has appealed for the public to keep a look-out after a spate of marine wildlife strandings reported in recent days.

Half of the six reports were live strandings, the group says, but only one animal was successfully returned to the water.

In Galway, a common dolphin live stranded with serious injuries but died shortly after IWDG members arrived at the scene.

Another common dolphin live stranded at Mulranny in Co Mayo. Local woman Catherine Hanley, who reported the stranding, managed to refloat this dolphin with her group and it has not been seen since.

In Co Donegal, a “very emaciated” Cuvier’s beaked whale live stranded at Dooey Beach in Downings, on the Rosguill peninsula, but died shortly after.

Elsewhere, the remains of three more cetaceans were reported around the coast in recent days.

In Rathmullen, Co Donegal, the carcass of a common dolphin appears to match video of a dolphin swimming in the area the previous day, suggesting a live stranding.

At Greenore in Co Louth, at the mouth of Carlingford Lough, a common dolphin in “very fresh condition” was reported to the local IWDG group.

And in Passage East, Co Waterford, a carcass in “very poor” condition has been logged as “dolphin species” as its advanced state of composition made further identification impossible.

The IWDG appeals for the public to report all strandings “so we respond immediately and monitor the status of our whales and dolphins”.

#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 - 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”.

#MarineWildlife - The Irish Whale and Dolphin Group (IWDG) has expressed its dismay at another record year for cetacean standings around the Irish coast.

The first eight months of 2017 alone have seen 201 recorded strandings - up 30% compared to the same period in the last two years.

“As in recent years, the numbers of dead common dolphins recorded are very high, with 78 records for this species to the end of August 2017 accounting for 39% of all strandings,” says IWDG strandings officer Mick O’Connell, who notes that the numbers of dead dolphins washing ashore in late winter and spring has grown unusually high.

“Even in a series of years with particularly high numbers of this species stranding since 2011, 2017 is well ahead of the previous two ‘record’ years by the end of August — 66 in 2016 and 53 in 2013.

“These are, of course, minimum numbers as we don't know how many dead animals go unrecorded and also many unidentified dolphins which aren't identifiable to species level are likely to be common dolphins,” he adds.

The IWDG is currently working with the Marine Institute, Department of Agriculture and National Parks and Wildlife service on a post-mortem scheme for common dolphins, striped dolphins and harbour porpoises which is hoped will shed new light on what might be causing this alarming rise in cetacean deaths.

Meanwhile, there was more positive news from the recent all-Ireland whale watch at the end of August, where three-quarters of the 20 sites around the island recorded sightings.

Around 1,300 whale watchers and wildlife enthusiasts spotted eight species of cetacean between them — with the busiest site at Loop Head in Co Kerry, where 120 lucky visitors got to see two humpback whales, five minke whales, six bottlenose and a whopping 50 common dolphins.

Other marine wildlife species spotted around the coast included Risso’s dolphins, blue fin tuna, ocean sunfish and grey seals.

More recently, the IWDG’s Celtic Mist embarked on a week-long survey of the waters around North and West Kerry, and its crew shared a video of some of their sightings.

#MarineWildlife - The Irish Whale and Dolphin Group (IWDG) has reiterated the need for localised stranding plans after the death of two common dolphins that stranded in Mayo's Blacksod Bay in late July.

Aoife Foley of the IWDG writes that the two dolphins were part of a pod of five that were spotted close to the shore at Mullaghroe Beach on Saturday 23 July.

A team from the Broadhaven Bay Marine Mammal Monitoring Programme joined local marine biologist Machiel Oudejans to move the dolphins, which did not appear to be injured or in obviously poor health, back into deeper waters and out to sea.

However, the following afternoon a member of the programme team saw that two of the marine mammals had stranded on the same stretch of beach, which Foley says is "notorious for common dolphin strandings in Blacksod Bay".

Despite best efforts, by Tuesday 26 July one of the animals had died and the other had to be put down by the National Parks and Wildlife Service.

#MarineWildlife - A number of dead minke whales found off the Dingle Peninsula in recent months have puzzled locals and experts alike, as TheJournal.ie reports.

The carcasses of three juvenile minkes have been spotted in the region since April, comprising 25% of all Irish minke whale standings since records began in 2000.

A fourth whale carcass was found on the shore at Killough in Co Down last week, according to BBC News.

But no one seems to know the reasons for these marine wildlife deaths, with the lack of a post-mortem scheme for whale strandings making matters even cloudier.

Mick O’Connell, strandings co-ordinator of the Irish Whale and Dolphin Group (IWDG), believes the phenomenon is localised to the Dingle Bay area.

Yet while the species is a regular visitor to the Blasket Islands and environs, O'Connell says it's "very unusual to have so many dead ones in the one small area, in the space of 10 or 12 weeks."

The same region also saw a number of unsubstantiated dolphin deaths in recent weeks, which one fishery expert suggested might be connected with the presence of so-called 'supertrawlers' fishing in the area.

Similar concerns were raised earlier in the year when a spike in common dolphin standings, primarily in the North West – totalling 28 for January and February alone – coincided with reports of supertrawler activity off the Dongeal, Sligo and Mayo coasts.

#MarineWildlife - Strandings of common dolphins for the first two months of the year are at their second highest since records began in 2002, says the Irish Whale and Dolphin Group (IWDG).

A total of 28 confirmed standings were recorded in the IWDG's strandings database in January and February of this year, just below 2013's worst figures so far when 31 were reported.

That compares to an average of fewer than six reports for the same period each year between 2002 and 2010.

The current decade has seen a significant jump in recorded figures, with 18 reports of dolphin standings in 2011 compared to just two in the same months in 2010.

Many of the dolphins found this year were recorded in the North West, a great number of them drowned according to post-mortem results, while others showed signs of being tangled in fishing gear, which suggests they were bycatch in the nets of supertrawlers that ply the seas off Donegal, Sligo and Mayo.

"While there is no conclusive proof of what vessels are involved, the evidence points to the presence of large (c.100m) foreign registered freezer trawlers fishing in Irish offshore waters."

That's according to the IWDG's strandings officer Mick O'Connell, who warns that "the number of bycaught dolphins that actually get washed ashore and recorded as stranded may be only a small percentage of the actual number of dead animals."

The IWDG reiterates the call for independent observers to be placed on supertrawlers in Irish waters, following controversy over the visit of one of the world's largest fishing boats last November.

In other news, Scotland's Press and Journal reports that a humpback whale was killed after getting trapped in fishing ropes in the Outer Hebrides.

The juvenile whale was found dead on the Isle of Barra this week with the "classic signs of having suffered entanglement."

#dolphinstrandings – As Afloat.ie reported earlier, a  County Mayo woman Ina Kruger successfully rescued a stranded dolphin at Easter on Keem beach, Achill. Originally rescued on Easter Sunday, the dolphin returned to the beach where the body of a second dolphin was discovered. Fortunately, the second rescue attempt was more successful and the dolphin hasn't been seen since.

#MarineWildlife - The Irish Whale and Dolphin Group (IWDG) has expressed its dismay at the continued rise in whale, dolphin and porpoise strandings around Ireland in 2013.

"The question was whether the numbers for 2012 were just a temporary ‘blip’ in the trend and would the figures for Ireland return to a more ‘normal’ 145 or so for 2013," writes IWDG strandings officer Mick O'Connell on the group's website.

"Well, as we head towards the start of winter, we can see that the answer is a most definite ‘no’."

O'Connell explains that by the end of the first week of October this year, the group had received validated reports for 175 cetacean stranding incidents - matching the total for the 12 months of 2012.

"With a good few weeks left until the years end, it’s likely that for the first time ever, the strandings database will receive 200-plus cetacean stranding records," he writes, adding that there is as yet "no explanation as to the cause or causes for the significant increase in figures" - though it's so far clear that the biggest increase is among common dolphins.

#MarineWildlife - The Guardian reports on new research which proves that military sonar has a direct effect on the behaviour of whales in our oceans - even leading to mass strandings.

The studies, part funded by the US Navy, found that beaked whales where particularly sensitive to sonar - and that even blue whales, the largest animals on earth, were distracted from feeding by the subsurface noise.

It's long been feared that the use of sonar is to blame for unusual behaviour among whales, who navigate and communicate with each other over long distances using sound.

As previously reported on Afloat.ie, the Irish Whale and Dolphin Group (IWDG) identified sonar activity by Royal Navy submarines as a possible cause of a the mass stranding of pilot whales in Donegal in November 2010, in which as many as 35 whales died.

Now for the first time, sonar has been proven to affect behaviour of cetaceans to a detrimental degree, confirming for many a connection between the use of sonar technology and recordings of whale and dolphin strandings identified since the 1950s. The Guardian has much more on the story HERE.

In more positive whale-related news, the IWDG reports that its next Cape Clear summer whalewatching course over the weekend of 26-28 July is "filling up nicely".

Places are still available but as it coincides with the tourism high season in West Cork, anyone interested is advised to book sooner than later to ensure they have someone to stay nearby.

The most recent weekend course over the June bank holiday witnessed numerous harbour porpoises and common dolphins, but its hoped the elusive whales will make an appearance next time round!

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.
