#MarineWildlife - Dolphin watchers around the UK and Ireland are keen to hear from anyone who may have spotted 'bad boy' dolphin Clet in recent weeks, as the Plymouth Herald reports.

Known as much for his distinctive dorsal fin and his aggression towards swimmers, the solo dolphin was first seen in Irish waters in the summer of 2014, and later befriended fellow 'dolphins-non-grata' Sandy, AKA Dusty, as his travels took him from West Cork to the Aran Islands.

By December that year he had moved on to the west coast of Scotland, and he was last sighted seven months ago off Portland, near Weymouth on Britain's south coast, where he had been spotted numerous times a year ago.

His disappearance since last August has worried marine wildlife observers including the Irish Whale and Dolphin Group, who have been tracking his progress since his first confirmed sightings in Brittany five years ago, though he was known to French fishermen since 2008.

#MarineWildlife - Cute by name, cute by nature: Sherkin, Buoy and Splash were returned to the wild after being nursed back to health by the volunteers at Seal Rescue Ireland.

As the Irish Examiner reports, the three young seals – rescued after tips from the public from locations in Cork and Kerry – were rehabilitated over the past three months at the new marine wildlife refuge in Courtown.

But they were finally fit to return to the open water last weekend at Fountainstown beach in Co Cork. The Irish Examiner has much more HERE.

As three return to Irish waters, another says adieu – as Clet the lone dolphin has now been spotted off the Dorset coast, according to the Bournemouth Echo.

Last spotted between Ireland and Scotland's west coast in December, the solitary cetacean first noted in French waters in 2008 appears to have completed a full loop around the island of Ireland.

Along the way he bypassed Dingle's famous resident Fungie and spent a few days in the company of fellow 'dolphina-non-grata' Sandy, also known as Dusty.

Now he's attracting the attention of locals at Portland, south of Weymouth, across the English Channel from his original splashing grounds.

Closer to home, conservationists in the the North West of England have released a video documenting the wealth of wildlife living in the Irish Sea as a reminder to political movers and shakers of the importance of its protection.

Groups such as the North West Wildlife Trusts have criticised Westminster for 'lack of ambition' over the past year since plans for a network of well over 100 Marine Conservation Zones (MCZs) were scaled back to just 27 approvals in November 2013.

More recently a further 23 MCZs were designated proposed, only two of which are out of out of seven proposals covering the waters between Britain's west coast and Ireland (updated Tuesday 17 March).

#MarineWildlife - Two months after striking up a friendship with fellow 'dolphina-non-grata' Dusty in his travels around Ireland, 'bad boy' bottlenose Clet has moved on again - this time to the west coast of Scotland.

According to the Island News & Advertiser, Clet appeared in the Sound of Mull in the Inner Hebrides during the week - his first confirmed sighting after he was seen frolicking with Dusty in Galway Bay - making for a rare sighting of a solitary dolphin in the area.

“To our knowledge, this is the first time that Clet has been recorded in Scotland, and in fact this is the furthest north he has been recorded to date,” said Dr Conor Ryan, sightings officer with the Hebridean Whale and Dolphin Trust.

Pádraig Whooley of the Irish Whale and Dolphin Group (IWDG) also hailed Clet's reappearance, saying: "The addition of Scotland after a two-month interval brings his known tally of passport stamps to five countries and counting, and shows the need for international collaboration when trying to monitor these highly mobile marine mammals.”

But Scottish dolphin-watchers be warned, as Clet may have been involved in an act of aggression towards swimmers near Galway city in early October.

#MarineWildlife - Clet the dolphin, previously spotted in West Cork after migrating across the Celtic Sea from France, has moved to the waters off Kerry in close proximity to Dingle's friendly resident Fungie.

As previously covered on Afloat.ie, the Irish Whale and Dolphin Group (IWDG) warned curious humans not to get too close to the bottlenose traveller after reports of aggression against swimmers.

But according to Sunday Independent, Fungie himself should have nothing to fear from Clet's visit should the two come into contact, as fighting among dolphins is only likely if competing for a mate.

"Fungie could be 40 to 50 years old at this stage and is unlikely to be interested in mating," said the IWDG's Padraig Whooley.

That's one of the only things experts do know about Fungie, who continues to baffle marine scientists with his general behaviour that's so atypical of his species. Independent.ie has more on the story HERE.

In other cetacean news, the IWDG reports "huge success" in its just-completed expedition to Cape Verde to survey the region's whale activity, recording humpbacks breaching for the first time off Ilhéu Branco in the West African archipelago.

#MarineWildlife - Late summer brings fin whales flocking to West Cork in big numbers, with the Irish Whale and Dolphin Group estimating at least 20 of the second-largest ocean species sighted between Seven Heads and Galley Head.

Indeed, as IWDG sightings officer Padraig Whooley writes, the gathering "is certainly the largest validated aggregation of this species so far this year" and comes some months ahead of the usual peak from October to December.

Recommended spots for watching these fin whale visitors - though you will need some decent binoculars to get the best views - are the aforementioned Galley Head and Seven Heads as eel as Cloghna Head, Dunworley and Sandscove.

Kerry has its own share of whale visitors, with a "lovely run" of humpbacks in recent weeks, while East Coast residents aren't left out, either, with a rare sighting of a minke whale in the Irish Sea some 20km off Bray Head over a week ago.

In other cetacean news, West Cork has become home to a new solitary dolphin in the form of Clet, a bottlenose who's been spotted in Glandore, Baltimore and Schull after time from Devon, Cornwall, South Wales and originally France.

Yet as IWDG welfare officer Paul Kiernan warns, Clet might appear cute but he's very much a wild animal, with reports claiming a swimmer off Sherkin Island was "aggressively pushed underwater by the dolphin".

Such stories, Kiernan writes, point "to the need for people to exercise common sense and extreme caution in how best to enjoy an interaction with this very large, apex predator."

He adds: "Bottlenose dolphins are not cute and cuddly, they are not our 'friends' and nor do they benefit in any meaningful or long term way from interacting with humans."

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.
