'Ireland's Ocean' is a major new four part ocean wildlife series for RTÉ One exploring the wonderful and diverse creatures that live in the seas around Ireland, from dolphins and sharks to plankton and the myriad of tiny colourful creatures that live in our shallow waters.

The series looks at the history of man's relationship with and response to the sea in Ireland, examining the common perception of creatures like dolphins and sharks ... are dolphins highly intelligent, sensitive creatures capable of healing sick children? Why are worrying numbers of dolphins washing up dead on our Atlantic coast? Are sharks terrifying animals waiting below the sea surface to eat us?

The truth transpires to be quite a surprise and leaves us with considerable food for thought. In other areas, the series takes us on a journey into wild and the colourful underwater world in the seas around Ireland, encountering an abundance of exotic creatures, many documented for the first time in this area.

Throughout the programmes, there is a strong sense of the interconnectedness of life, and natural balance within this world, as creatures depend on each other's presence to sustain life.

The first programme this Sunday takes a look at some of the 27,000 common dolphins living in Irish waters with scientists Dr Joanne O'Brien and Dr Simon Berrow.

The second programme, Sunday 29th June at 6.30pm gets up close with some of the 40 shark species and 30 ray species that live in Irish waters with Dr Maurice Clarke at the Marine Institute, as well as following the conservation efforts of Dr. Edward Farrell, Irish Elasmobranch Group, placing satellite tags on porbeagle sharks off Donegal, in a Marine Institute research programme.

Programme three focuses on life in the shallow seas around Ireland which are some of the most fertile on Earth. Storms churn up nutrients from the sea floor which combine with sunlight to create a fertile and abundant ecosystem.

The final programme looks at Ireland's ocean habitats.

Ireland's Ocean begins on Sunday June 22nd at 6:30pm on RTÉ One and runs for four weeks.

'Ireland's Ocean' was produced by Sea Fever Productions for RTÉ and financed under the Broadcasting Authority of Ireland's Sound & Vision scheme, and also by the Environmental Protection Agency.

#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 confirmed that a dead dolphin calf found washed up near Doolin in Co Clare almost three years ago was likely born to Dusty the dolphin, who's been the subject of much controversy over recent weeks.

Dr Simon Berrow of the IWDG writes that a sample was taken from the dead calf and stored for future genetic analysis. Similar samples were collected from Dusty by local diver and award winning photographer George Karbus, and these were sent to marine researcher Marie Louis at the Centre d’Etudes Biologiques de Chizé, France as part of her PhD project.

Louis recently analysed these samples and determined that Dusty and the calf shared the same haplotype, a genetic marker that points to a very likely relation between the two dolphins.

"Given the recent behaviour of Dusty in Doolin and suggestions locally that she gets more aggressive when she is pregnant, this latest analysis is relevant as it shows that Dusty is sexually mature, interacts and mates with other dolphins and has at least on one occasion had a calf," writes Berrow.

Last week the victim of an attack by the 14-year-old female bottlenose dolphin at Doolin has called for a total swimming ban in the area.

#MarineWildlife - A fantastic snapshot of a surfing dolphin has netted a Clare-based photographer the prestigious top prize at the British Wildlife Photographer of the Year awards, as the Mail Online reports.

Czech-born George Karbus captured the winning image, titled 'In the Living Room', while diving off Ballintoy in Co Antrim, when he encountered the "playful" bottlenose dolphin "that suddenly started to surf the deep tube inside the waves".

As reported by TheJournal.ie, Karbus added: “Water visibility is always very limited in Ireland, and I was very lucky to get a shot like this.”

The photographer also topped the coastal and marine category at this year's awards, and his prize photo will be featured in a book compiling the top entries.

Karbus was previously featured on Afloat.ie in 2011 for his stunning images of fin whales and dolphins feeding off Hook Head in Co Wexford.

#DolphinAttack - A woman who suffered serious injuries after being struck by the snout of Doolin's dolphin resident Dusty has criticised the lack of warning signs in the harbour at the time.

As RTÉ News reports via the Irish Independent, Valerie Ryan is calling for a total swimming ban in the area after suffering eight spinal fractures, two broken ribs and lung damage in the incident on 28 July last.

The self-employed osteopath has been forced out of work for six months due to her injuries.

Hers was the fourth such altercation with Dusty, a 14-year-old female bottlenose dolphin, recorded at that point this summer.

It has since emerged that the dolphin may have been acting aggressively in reaction to mistreatment by certain members of the public on various occasions.

Warning signs have since been erected in the area by Clare County Council, in line with advice from the Irish Whale and Dolphin Group that no one should swim with any of the whales or dolphins that frequent Ireland's waters - activity that puts both humans and cetaceans at risk.

"This dolphin is a wild animal and people should take serious account of that," said Liam Griffin, water safety officer with Clare County Council.

#MarineWildlife - A dolphin from the Irish Sea that became stranded on sandbanks in the River Dee in North Wales was safely transported back to deeper waters aboard Flint’s inshore RNLI lifeboat.

RNLI volunteers from Flint were called to Airbus UK’s loading facility, just downstream from Saltney Ferry, at around 11.30am on Thursday morning (22 August) to attend to the dolphin that was in difficulty in the shallows of the river estuary.

RNLI lifeboat operations manager Alan Forrester confirmed that the crew put the dolphin inside a stretcher for transfer to the lifeboat, and that a representative from the British Divers Marine Life Rescue was on board to monitor the cetacean's condition.

"The dolphin is a fair size, so we’ll go at a very slow pace until we reach deeper waters, where we will be met by the Rhyl all-weather RNLI lifeboat," said Forrester during the mission.

The dolphin, originally named 'Dave', has since been renamed 'Davina' after she was identified as being female.

Davina was released around the North Rhyl Flats as if she were set free in any shallow waters it's feared she would become stranded again.

#MarineWildlife - The coastguard were beaten to the punch by a group of children who helped a stranded dolphin back into open water in Co Clare, as TheJournal.ie reports.

Kilkee Coast Guard were dispatched after reports that the striped dolphin was trapped in the shallow rock pools at Kilkee Beach, but the unit arrived on scene just in time to see the cetacean swim away unscathed.

The Irish Whale and Dolphin Group's Dr Simon Berrow confirmed to TheJournal.ie that locals had seen a number of other dolphins swimming in the area, at least one of which almost became stranded in shallow water.

#MarineWildlife - The Irish Whale and Dolphin Group (IWDG) has urged people in Doolin to refrain from swimming with or even approaching Dusty the dolphin after it emerged the cetacean has been tormented by loutish visitors.

As reported on Afloat.ie last week, a woman was hospitalised after being struck by the dolphin's nose in what was just one of a spate of incidents involving the 14-year-old female bottlenose at the Co Clare town.

However the Irish Examiner reports that the marine mammal may only be reacting to antagonising behaviour such as fin grabbing by some swimmers and visitors in the Doolin area - with one group of campers allegedly trying to pour cider down her blowhole.

Speaking after the latest attack late last month, Dr Simon Berrow of the IWDG commented: "It is IWDG policy to discourage people swimming with whales and dolphins in Ireland. The risk is not only to humans but also to the dolphin as habituation to humans increases risk of injury or death to the dolphin.

"Around 80% of such interactions worldwide end up in the death or severe injury of the dolphins involved."

#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.

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.
