#Dolphins - It was a happy Easter for one young dolphin that was rescued from stranding on Achill Island by some quick-thinking coastguard volunteers.

As TheJournal.ie reports, the juvenile dolphin was one of two reported stranded on Keem Beach early on Sunday morning.

On arrival at the scene, the local Irish Coast Guard team found one of the two had died, but officer-in-charge Colin Honeyman leapt into action to save the remaining youngster.

Taking to the sea in his wetsuit, and with some help from a nearby fishing boat, he swam with the dolphin under his arm out to deeper water, where "he seemed to get a new lease of life and just swam off - he really went for it."

#Dusty - Renewed warnings have been made to the public to keep a wide berth from Doolin's dolphin Dusty as the Irish Examiner reports she's "more jumpy" than usual.

Last summer the female bottlenose earned a degree of infamy after attacking a number of bathers in the Co Clare town, one of whom suffered eight spinal fractures, two broken ribs and lung damage in their altercation.

As we get closer to this year's summer, it may be tempting to join Dusty in the water for typical dolphin frolics, but Vanessa Fagan-Vanhorn of Dolphin Day Ireland strongly advises against it.

“[Disty] is definitely more jumpy and easier to startle than she used to be," she says. "The incidents of last summer do seem to have had an effect and her behaviour has changed."

#Dolphins - Marine photographer Myles Carroll snapped some beautiful shots of a dolphin pup frolicking in the waves off Hook Head last weekend, as TheJournal.ie reports.

The baby was just one of a near 40-strong dolphin pod sighted off the Wexford coast in recent days, just in time for the Irish Whale and Dolphin Group's latest cetacean spotting trip this weekend on board the Celtic Mist.

#MarineWildlife - The dolphin death toll on America's Atlantic coast caused by a measels-like virus now exceeds 1,000 - and marine scientists have warned the Guardian that the epidemic shows now signs of slowing down.

As reported in August on Afloat.ie, more than 300 deaths of bottlenose dolphins found between New York and North Carolina - more than 10 times the average for the time of year - were connected with the presence of morbillivirus.

Researchers speculate that the marine mammals have somehow lost their natural immunity to the disease, which first appeared in the late 1980s when it killed a known 740 cetaceans - but factors due to climate change have also not been ruled out.

The previous outbreak of morbillivirus wiped out half of all of the Eastern Seaboard's coastal migratory dolphins, whose population currently stands at more than 39,000 thanks to conservation efforts since that last epidemic.

It's not believed there is any connection between the morbillivirus resurgence on the far side of the Atlantic and the continued rise in dolphin strandings around Ireland.

However, the Irish Whale and Dolphin Group (IWDG) has identified a different threat to Irish cetaceans, calling for a ban on pelagic fishing within Special Areas of Conservation in West Cork and the Shannon Estuary in order to preserve a key food source for local dolphins and porpoise.

"The removal of herring and sprat could have a significant impact on [cetaceans'] foraging efficiency and hence on the life histories of harbour porpoise and bottlenose dolphins, especially their reproductive fitness," says the IWDG's Dr Simon Berrow.

#MarineWildlife - The Irish Mirror says it's played a helping hand in granting a young boy's biggest Christmas wish after a marine conservation group reached out to his heartbreaking plea to swim with dolphins.

Conservation group Sea Shepherd read the 12-year-old's letter to Santa that was published in the Mirror earlier this week, in which he told of his abusive childhood and his "lifelong dream" to see Winter the dolphin in Florida.

While Sea Shepherd is not able to fly the boy to Florida, they have offered to take him to see dolphins in their natural habitat off West Cork and show him "that inspiration can come from the wild dolphins around our coast," according to the campaign group's Irish director Sue Anthony.

#MarineWildlife - The Irish Times has posted exclusive video of a dolphin pod enjoying the feeding bounty off Baltimore this week - just a sample of the intense marine wildlife activity around Ireland's coasts in recent days.

Pádraig Whooley of the Irish Whale and Dolphin Group (IWDG) told the IT that the current band of high pressure over Ireland "is making it much easier for us to spot them" as they stream to our shores along with various whale species to feed on migrating herring shoals.

But it hasn't been all good news, as the IWDG writes of a mass stranding of up to 13 common dolphins - mostly mother-and-calf pairs - on the Mullet Peninsula in Co Mayo last Sunday 24 November.

Those that were not able to refloat themselves were helped back into deeper water by locals. But a dead adult female was still found at Elly Bay the following day, with its calf in the water nearby - followed later by another stranded adult female and calf who had to be euthanised.

And the day after two more adult female and a male calf were found dead on the beach, while two more adults and calf were refloated and subsequently beached again.

IWDG records show 34 reports of live strandings on the Mayo coast, 17 alone on the Mullet Peninsula.

#DolphinSwim - Two children with disabilities from Northern Ireland recently enjoyed the trip of a lifetime to Florida where they got to swim with some friendly dolphins.

As the News Letter reports, 14-year-olds Ryan Shannon from Belfast and Michael Bowes from CO Tyrone became firm friends on the trip, organised by charity Dreamflight for youngsters with disabilities seriously ill children.

Their busy week of activities, which included visits to Walt Disney World and Universal Studios, included a 30-minute swim with dolphins at Discovery Cove in Orlando's SeaWorld marine wildlife park - a clip of which you can see above (c/o the Belfast Telegraph).

#MarineWildlife - Five Risso's dolphin calves spotted by researchers off the Isle of Man this summer point to the waters of the Irish Sea as a breeding ground for the gregarious marine mammals.

As BBC News reports, the five calves were seen north of the Calf of Man at the end of July.

And according to a spokesperson for the Manx Whale and Dolphin Watch: "It means Manx waters must be important to the breeding population of Risso's dolphins in the Irish Sea."

The waters between the east coast of Ireland and north-west England and Wales are known to be teeming with dolphins of different species, with video of a dolphin 'superpod' wowing ferry-goers earlier this year.

#DolphinDeaths - Hundreds of bottlenose dolphins have died in strandings along the east coast of the United States this summer - and a measles-like virus could be to blame.

As The Irish Times reports, the National Oceanic and Atmospheric Administration (NOAA) is currently investigating the extraordinary die-off, which has been tentatively connected to morbillivirus, an immune system suppressor similar to the virus that causes human measles.

In numbers not seen since the late 1980s, as many as 333 dolphin carcasses have been found on the shoreline between New York and North Carolina, more than 10 times the average for this time of year.

Researchers from universities and marine institutes are concentrating on the Virginia coastline, where the majority of the dead cetaceans have been found, and believe they have identified evidence of morbillivirus in nearly all sampled carcasses.

Wired Science says scientists do not yet know what caused the outbreak, though they speculate that dolphins may simply have lost their natural immunity to the virus since the last attack.

And according to the NOAA's Teri Rowles: “At this point, there isn’t anything to stop the virus.”

As of yet there are no indications if the virus could migrate to dolphin populations on this side of the Atlantic, particularly in the designated cetacean sanctuary of Irish waters.

#MarineWildlife - A humpback whale new to Irish waters has been confirmed by the Irish Whale and Dolphin Group (IWDG).

Photos of the humpback's fluke and dorsal fin captured by Nick Massett off Clogher and Sybil Heads in West Kerry at the weekend were examined by the IWDG's catalogue experts who have determined that the whale is a new arrival - and one with a fluke colouring that's rarely seen in Irish waters.

Details have since been sent to Allied Whale in the US state of Maine - which curates the North Atlantic humpback whale catalogue - to see if a match can be made among its database of more than 7,000 fluke images.

Meanwhile, Wildlife Extra reports that sailors in the Irish Sea are urged to keep a lookout for a large group of minke whales.

The group includes three juveniles and a calf previously spotted some 19 miles east of Ireland's Eye near Howth.

"Although sightings of Minke whale are to be expected in these waters, such a large group is a rare occurrence," said Danielle Gibas, sightings officer with the UK's Sea Watch Foundation, which is organising Britain's annual National Whale and Dolphin Watch this week till 3 August.

And in other cetacean news, scientists claim that dolphins call each other by name, calling back to the sound of their signature whistle but ignoring whistles that aren't theirs.

Herald.ie reports on the findings by marine scientists at the University of St Andrews, who studied a bottlenose dolphin group off the east coast of Scotland.

Using underwater speakers, they played synthesised versions of dolphin whistles they'd identified with particular dolphins to determine their reactions.

They were surprised to find that individuals called back after hearing their own 'name' but ignored others, whether they were for dolphins in the same group or strangers.

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.
