#MarineWildlife - Seven dolphins and two beaked whales have stranded on beaches in the northwest in events described as "unusual" by the Irish Whale and Dolphin Group (IWDG).

On the Mullet Peninsula, a group of seven common dolphins - comprising five adults and two juveniles - live stranded at Tarmon Beach on Sunday 12 May.

Though initial attempts to refloat them were successful, one of the juveniles was later found dead and the other was euthanised due to poor health.

Meanwhile in Donegal, the fresh carcass of a female True's or Sowerby's beaked whale was found on Sunday evening on Five Fingers Stand at Inishowen - some days after a reported live stranding of a Sowerby's beaked whale on the Welsh coast.

The Inishowen stranding was followed yesterday 14 May by the discovery of a dead beaked whale calf at Trawbreaga Bay, in what is believed to be a connected stranding.

Samples of the adult female were taken in order to confirm the species, either of which would mark a rare cetacean record for Ireland - the first since 2009.

#DolphinExhibition - Balbriggan Maritime Museum has opened a new public display in Balbriggan Tourist Office on Quay Street near Balbriggan Harbour.

On show is a Whale and Dolphin Exhibition, bones, models and general information to celebrate the biodiversity of sea mammals off the coast. This follows the previous popular 'Cannon Balls Exhibition'.

Appropriately, 'Water & Biodiversity' is the theme of the 2013 International Day for Biological Diversity which falls on Wednesday, 22nd May.

Balbriggan Maritime Museum volunteers have assembled bones from many sea animals, such as a vertebra from a Fin Whale, the second largest whale in the world growing to 88ft in length. No wonder this bone is too heavy for one person to lift!

The Humpback Whale model, in real life, is about half the length of a Fin Whale and weighs only 40 tonnes! Even so, Humpback Whales, which are seen in the Irish Sea, would be too big to fit into Balbriggan Courthouse!

Smaller skulls from Common Dolphin, Pilot Whale and Grey Seal, as well as a Minke Whale jawbone can also be examined during May when this Whale and Dolphin Exhibition will be on display from Tuesday to Sunday when the Balbriggan Tourist Office is open.

#MarineWildlife - The Northern Ireland Environment Minister says the new Marine Bill put before Stormont marks a "turning point" for the North.

As 4NI reports, this week saw the fourth stage of the Marine Bill in the NI Assembly as well as the launch of a consultation strategy for Marine Protection Areas (MPAs).

Should it be enacted in legislation, the Marine Bill - strongly supported by the RSPB among others - would give the Assembly powers to select and manage Marine Conservation Zones (MCZs) to safeguard the North's marine biodiversity.

Minister Alex Attwood commented: "Northern Ireland’s seas are home to some of the world's most spectacular wildlife and habitats, and have the potential to power our nation through wind and wave and create thousands of new jobs.

"We have reached a turning point and must modernise in order to meet increasing and competing demands on our seas."

The Marine Bill also provides for the creation of a National Maritime Plan which covers all aspects of the marine environment from wildlife to investment in tidal and offshore wind power.

#MarineWildlife - The Irish Whale and Dolphin Group (IWDG) is marking 20 years of researching the dolphins of the Shannon Estuary.

As the IWDG's Dr Simon Berrow relates, it was not an auspicious start on 2 May 1993 when the first research trip on the estuary returned after five hours without having seen a single cetacean.

But the following day brought a bounty, with 16 dolphins across three different groups located by the IWDG - the beginning of two decades of sightings and recordings for the Shannon Dolphin Project, which has identified around 230 individual dolphins to date.

Thanks to that project, we know today that at least six of those dolphins first seen in 1993 are still in the estuary as of last year.

The Shannon Dolphin Project now has a website explaining its achievements and the work of the Shannon Dolphin and Wildlife Foundation (SDWF) over the years.

Meanwhile, Afloat reader Karl Grabe has also produced a spectrogram and edit of hydrophone recordings captured by Dr Berrow of Shannon dolphins just a few weeks ago.

Grabe previously uploaded a wonderful snippet of dolphins vocalising in the estuary late last year.

#Fungie - An Irish marine expert suspects that Dingle's most famous resident may be an escapee from a British dolphinarium.

Dingle Oceanworld director Kevin Flannery told the Irish Independent that Fungie the dolphin could have slipped through the sluice gates of any one of a number of dolphinariums on the south coast of England amid "huge objections to holding marine animals in captivity".

As previously reported on Afloat.ie, the male bottlenose dolphin appeared out of nowhere in Dingle's harbour in 1983 and has made his home there ever since.

In the three decades from then he has been credited with having "rescued" the village as his frolics brings countless tourists to the peninsula every year, as Flannery told the Irish Examiner.

This week's Féile na Bealtaine in Dingle celebrates the 30th anniversary of the arrival of the Kerry village's cetacean mascot, and many visitors are expected to line up for boat trips out of the harbour to meet him face to face.

While the Irish Whale and Dolphin Group (IWDG) doesn't recommend swimming with a wild dolphin such as Fungie, the group's Nick Massett describes him as "friendly, intelligent, and very aware of where people [are] in the water".

Among the festival activities this week will be a film screening and exhibits paying tribute to Ireland's own 'Flipper'.

Féile na Bealtaine runs from 2-6 May with events throughout the Dingle Peninsula.

#MarineWildlife - Marine scientists have joined conservation groups in a chorus of opposition to the British government's apparent backtracking on plans to protect marine wildlife in the seas around the UK - including between Britain and Ireland.

As The Guardian reports, 86 academics have written to UK Environment Minister Richard Beynon, Environment Secretary Owen Paterson and Prime Minister David Cameron, urging them to rethink the neutering of proposals for Marine Protection Zones (MPZs) around the United Kingdom.

Earlier this month, as reported on Afloat.ie, environmentalists expressed disappointment over Westminster's slow progress on the issue, coming after news that just 31 of a potential 127 sites would be designated as protected.

It has since emerged that even these 31 sites so not include full protection for wildlife from destructive fishing and dredging activities.

Prof Callum Roberts of the University of York told The Guardian: "We have seen spectacular devastation in the Irish sea in the last 20 years, for example, due to scallop dredging and prawn trawling.

"As fish stocks get ever more squeezed, the use of ever more destructive gear is spreading. This is happening now and protection is long overdue."

He added: "Even if all 31 MPZs were established, it will fall far short of what is needed to recover and safeguard English seas."

#MarineWildlife - The trio of bottlenose dolphins who took up residence close to Bunratty Castle recently have apparently moved back out to deeper water after growing concerns for their well-being.

As previously reported on Afloat.ie, the dolphins had made their home opposite Durty Nellys pub in the Ratty River, which flows into the Shannon Estuary.

Simon Berrow of the Irish Whale and Dolphin Group (IWDG) explained that it's not unusual for dolphins to forage for food in waterways that feed into the estuary, though they usually return to the main catchment on their own shortly after.

With fears that their acoustic abilities were impaired, preventing them from navigating downstream past a series of bridges and concrete pillars between them and the main watercourse, a rescue attempt had been planned for late last week.

But as the Clare People reports, this was called off as the dolphins were spotted less and less frequently in the area.

Later hydrophone tracking by the IWDG led experts to discover that the cetaceans were able to come and go as they pleased.

Despite this, dolphins only have a limited ability to survive in fresh water, and can develop serious kidney and skin problems if exposed for a significant length of time.

#MarineWildlife - An upcoming research cruise by the Irish Whale and Dolphin Group (IWDG) is set to follow the path of a famous whaling voyage embarked on by an Irish Times journalist more than 100 years ago.

The paper reports on the pending mission by the marine wildlife charity's Celtic Mist research vessel that will retrace the movements of Crawford Hartnell from the site of what was then a Norwegian whaling station in the Inishkea Islands off the Mullet Peninsula in Mayo to a point 160km west where Hartnell report the harpooning of two whales.

Hartnell's accounts of his whaling adventure are remembered today for their blood-soaked vividness - but the IWDG's advances are altogether more friendly.

Rather than harpoon their quarry, the researchers on board the Celtic Mist will be on the lookout for baleen and beaked whales to count - and will also be teaching IWDG members how to identify species, how to carry out sea-bound surveys and how to use hydrophones to identify cetaceans by the sounds they make beneath the waves.

#MarineWildlife - Three bottlenose dolphins have made a new home close to a famous tourist watering hole in Co Clare.

According to the Irish Independent, the trio have taken up residence next to Durty Nellys pub in the Ratty River, which flows past Bunratty Castle into the Shannon Estuary.

The Irish Whale and Dolphin Group (IWDG), which has been tracking the group, believes they originated from a larger group populating the estuary.

As the IWDG's Simon Berrow explains, such dolphins are known to forage for food in rivers that feed into the estuary, and will return to the main catchment on their own.

While the risk of stranding in the shallower waters of rivers is unlikely, there is growing concern that the dolphins have been in the area for longer than expected.

"We can't rule out the possibility that their acoustic abilities may be impaired by the series of bridges and concrete pillars that span one of the bridges, and that they may be finding it difficult to navigate as a result of an 'acoustic trap'," says Berrow.

The IWDG says it is in discussion with the National Parks and Wildlife Service as to what options are available to step in to shepherd the trio back to the Shannon Estuary if necessary.

#MarineWildlife - UK environmentalists have expressed their disappointment at the British government's slow progress on developing its promised network of Marine Conservation Zones (MCZs), as the Belfast Telegraph reports.

The consultation period was for the proposals was set to end on Sunday 31 March - amid fears among conservation groups that were realised some months ago with the news that just 31 out of a potential 127 sites would be designated as protected for marine wildlife and plantlife by the end of this year.

It's being reported that Environment Minister Richard Beynon is blaming budget cuts and the high cost of scientific assessment for the slowdown in progress on the government's side.

"I want to do as many zones as we can for as little as we can," he told the BBC. "People have waited many years for this; we will designate the first tranche in September and will announce the next lot for consultation then."

The Royal Yachting Association (RYA) said in December that it was "encouraged" by the British government's "sensible" phased approach to the MCZ plans.

However, conservationists like Jolyon Chesworth from the Wildlife Trusts argue that their interests are being asked "to compromise on a compromise".

Chesworth added that the original 127 zones "were only nominated after very long discussions with anglers, sailors and the fishing industry".

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.
