#MarineWildlife - Dusty the dolphin has injured yet another swimmer off Doolin Pier in Co Clare in the latest of a recent spate of incidents, as The Irish Times reports.

Last night a woman was hospitalised after being struck by the dolphin's nose in the kidney area, leaving her "badly bruised and shocked by the incident".

It's since emerged that this was the fourth such attack by the bottlenose dolphin in the past month.

The cetacean responsible - a 14-year-old female - has made Doolin her home after many years in the Fanore area, and has apparently been responsible for a number of attacks on swimmers over the last two years.

But visitors continue to swim with the dolphin despite warnings by the Irish Whale and Dolphin Group (IWDG), which discourages any interference with the protected species.

The Irish Times has more on the story HERE.

#MarineWildlife - The Irish Whale and Dolphin Group (IWDG) has welcomed the designation of a new special area of conservation (SAC) for marine wildlife in Dublin Bay.

As reported yesterday on Afloat.ie, Heritage Minister Jimmy Deenihan was on board the IWDG's research vessel Celtic Mist in Dun Laoghaire on Tuesday 16 July to lance the group's new atlas of marine mammal distribution in Irish waters - an event at which he also confirmed his extension of the protections already afforded to whales and dolphins over a number of coastal sites around Ireland.

The Dublin Bay SAC, running from Rockabill off Skerries to Dalkey Island, is one of the six new sites proposed by the minister's department late last year.

The list also features Blackwater Bank in Co Wexford, the West Connacht Coast, Hempton's Turbot Bank in Donegal, the Porcupine Bank Canyon off Kerry and the South-East Rockall Bank.

According to The Irish Times, the Dublin Bay conservation zone alone covers a sea area of 27,000 hectares and will extend protections under the 1992 EU Habitats Directive to the area's population of harbour porpoises.

#MarineWildlife - Minister for Arts, Heritage and the Gaeltacht Jimmy Deenihan was on board the Irish Whale and Dolphin Group's (IWDG) research vessel Celtic Mist yesterday 16 July to launch a new atlas of marine mammals in Ireland's coastal waters.

The Atlas of the Distribution and Relative Abundance of Marine Mammals in Irish Offshore Waters marks the culmination of six years of surveys involving more than 1,000 says at sea, and provides up to date information for 19 species of cetaceans: whales, dolphins and porpoises.

Ireland is home to a remarkable diversity of whales and dolphins, and the new atlas shows how common and widespread some of these species are - from the harbour porpoise and common dolphin to the much larger fin whale.

Not all Irish cetaceans are so common, however, and the atlas also highlights the importance of Irish waters for some of the Atlantic’s rarer deepwater species such as the sperm whale and several beaked whales.

These are species about which very little is known, the IWDG says more work will be required in the coming years to allow a better understanding of the conservation requirements of these animals.

Every six years, Ireland is obliged to report on the conservation status of all of its marine mammals as part of its commitments under the European Union’s Habitats Directive. The data from this atlas has already proved invaluable in underpinning Ireland’s 2013 report to the European Commission.

Speaking at the launch yesterday in Dun Laoghaire, Minister Deenihan commended the work undertaken to produce the atlas.

“This fine atlas is the culmination of many years of work by a large number of people and I’m happy to note that it was produced under a project funded over several years by my department in collaboration with the Marine Institute," he said.

"As minister, I have also extended the protection afforded to whales and dolphins through the designation of additional marine special areas of conservation. I would like to thank the Irish Whale and Dolphin Group for this excellent publication.”


The atlas is available as a PDF to download HERE.

#CelticMist - The Irish Whale and Dolphin Group's (IWDG) research yacht Celtic Mist is currently docked in Dun Laoghaire awaiting the start of The Gathering Cruise around Ireland.

As previously reported on Afloat.ie, the 19-day event will see some 100 cruising boats proceed along the east and south coasts of Ireland from Dublin to Cork and Kerry.

Along the way they will be recording any sightings of whales or dolphins along the way using forms supplied by the IWDG.

Celtic Mist will join the flotilla as it departs Dun Laoghaire Harbour on 18 July headed for Kinsale on 24 July, and a second leg from Kinsale to Dingle from 25 July to 1 August.

And the IWDG is currently offering places on board to all members for both week-long legs of the cruise.

The vessel has eight berths that will comfortably sleep a team of one skipper and seven crew - indeed, anyone taking up this offer will be expected to prepare meals and perform other sailing duties!

For more details on how to join The Gathering Cruise on board Celtic Mist, see the IWDG website HERE.

In the meantime, Celtic Mist is offering all IWDG members a chance to sail on day trips from Dun Laoghaire this week - email [email protected] for details.

#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!

#MarineWildlife - In a week that saw the Isle of Man's first sighting of a humpback whale for three years, BBC News reports on the strange discovery of a rare species of dolphin two miles inland from the shore in Co Donegal.

The carcass of an Atlantic white-sided dolphin was found on a hillside near Meenbanad with head injuries - but no one knows how it got there.

Pádraig Whooley of the Irish Whale and Dolphin Group (IWDG) said it's most likely that someone found the dead cetacean on the beach and took it to the hillside to decay so that its skeleton could later be retrieved.

The dolphin is thought to be one of a pod that beached at Traigheanna Bay in Dungloe on 21 June. The species is a rare sight in Irish coastal waters, said Whooley, because they tend to feed much further out at sea.

In other stranding news, the IWDG reports that a bottlenose dolphin who live stranded at Beal in Co Kerry last summer has been recorded in the Shannon Estuary with her calf on a number of occasions this month and last.

The Shannon Dolphin and Wildlife Foundation has more on the sightings of the dolphin they now call Sandy Salmon.

#MarineWildlife - The 21st year of dolphin research in the Shannon Estuary is off to an amazing start after the first ever dolphin recorded in the estuary was spotted on the Kerry coast.

As the Shannon Dolphin and Wildlife Foundation (SDWF) reports, the dolphin known as 'No 1' was sighted in Brandon Bay on Saturday 25 May swimming in a group of three.

No 1 is happily a familiar sight in the region, having been recorded most years since the project began in 1993.

"It has long been known that Shannon dolphins regularly use Tralee and Brandon Bays but how important the area is in not clear," says the SDWF on its blog. "If we are to protect the Shannon dolphins we need to ensure we identify all their important habitats and extend protection to these areas if necessary."

Meanwhile, its been confirmed that the trio of bottlenose dolphins who took up residence near Bunratty Castle in the spring have been observed in the mainstream of the Shannon Estuary.

The three were spotted on the first monitoring trip of the summer from Kilrush last week by SDWF researchers of Moneypoint.

"This demonstrates again the value of long term monitoring and the power of a photo ID catalogue to monitor the Shannon dolphins," says the SDWF blog.

In other cetacean news, an in-depth discussion of the Shannon's dolphins and the Irish Whale and Dolphin Group's (IWDG) research of bottlenose dolphins around the Irish coastline was broadcast on Derek Mooney's afternoon show on RTÉ Radio 1 recently.

A podcast of the 30-minute segment of Mooney Goes Wild from Friday 31 May is available to download HERE.

#MarineWildlife - Tonight's Nature on One on RTÉ Radio 1 joins the Irish Whale and Dolphin Group (IWDG) on a quest off Hook Head to find the majestic fin whale.

As TEN reports, Colin Stafford Jones was on board with the IEDG's Pádraig Whooley on a mission to track down the world's second largest animal - not only the biggest example of marine wildlife behind the incredible blue whale.

Their adventure will be broadcast tonight (Sunday 9 June) from 7pm on RTÉ Radio 1, and will be available to listen online afterwards via the Nature on One website HERE.

#MarineWildlife - Another beaked whale stranding has been recorded on the Irish coast just weeks after two of such creatures were found in Donegal.

A ranger with the National Parks and Wildlife Service (NPWS) made the discovery at Aillebrack in Co Galway on the evening of 27 May.

The 5m carcass of a female - like the female and juvenile found in the northwest - is thought to be either a True's or Sowerby's beaked whale.

Mick O'Connell, strandings officer with the Irish Whale and Dolphin Group (IWDG), says the latest stranding "raises new questions", with suspicion that its death may be linked to the face of the Donegal pair earlier this month.

As previously reported on Afloat.ie, beaked whales are a rare occurrence in Irish waters, with the last record before this month' stranding made in 2009.

#MarineWildlife - A gray whale has been sighted many thousands of miles from its usual Pacific swimming grounds in the South Atlantic.

As Pádraig Whooley writes on the Irish Whale and Dolphin Group (IWDG) website, the whale was spotted in the last week in Walvis Bay, Namibia - only the second ever confirmed sighting of the marine species in the Atlantic Ocean, and the first south of the equator, since records began.

Previously a solitary gray whale was tracked in the Mediterranean in May 2010 from the coast of Israel to Barcelona in north-eastern Spain.

That was the first time a gray whale had been seen anywhere east of the Pacific Ocean following the presumed extinction of the Atlantic gray whale in the 17th century.

Whooley calls the latest sighting "a fascinating discovery" and says it "points strongly towards a dramatic shift in distribution facilitated by climate change.

"This is a timely reminder that we should never assume to know what species occur in our local waters, especially when this species seems to have literally come back from the dead."

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.
