#MarineWildlife - If you've ever wanted to get closer to Ireland's marine wildlife, a new series of weekend excursions in West Cork may be just the ticket.

The Southern Star reports on the 'Discover Wildlife Weekends' being run from Rosscarbery by local company Ireland's Wildlife starting this April, where those taking part will be led by expert guides to explore the coastal region and have the best opportunities to spot the many species of whales and dolphins that visit our shores.

Weather permitting, the weekends will also involve some offshore whale watching in the company of 'whale watch supremo' Colin Barnes and the Irish Whale and Dolphin Group's (IWDG) sightings co-ordinator Pádraig Whooley.

And birdwatching will also be a feature, as West Cork is a hotspot for our feathered friends - from merlins and peregrine falcons to coastal waders and more exotic fowl that skirt our coasts on their spring migrations.

The Southern Star has much more on the story HERE.

Meanwhile, marine sector stakeholders have expressed their concerns over the designation of six new offshore marine areas by the National Parks and Wildlife Service.

As previously reported on Afloat.ie, the six sites at Blackwater Bank in Wexford, the West Connacht coast, Hempton's Turbot Bank in Donegal, the Porcupine Bank Canyon off Kerry, the South-East Rockall Bank, and the stretch from Rockabill to Dalkey Island off Dublin have been proposed for designation as Special Areas of Conservation (SACs) to protect marine habitats and species listed on the 1992 EU Habitats Directive.

But at a recent meeting at the Irish Farm Centre in Dublin, a coalition of fish farmers, fishermen and marine energy stakeholders have hit out at what they characterise as "the appalling handling of inshore designations since the 1990s by the State", which they claim "has resulted in hundreds of job losses and a flight of serious investment" from Ireland's coastal areas.

“Our experience of the Irish Government’s application of the EU Habitats Directive has been a saga of mismanagement, foot dragging and buck-passing which has left over 500 fish farming licences in limbo for over 10 years and a backlog of red tape and bureaucracy which could see producers waiting until 2020 and beyond for simple renewals which are vital to underpin their businesses," said IFA aquaculture executive Richie Flynn.

"These new offshore SACs will have the same effect of preventing any fishing, marine energy or aquaculture being carried out in these areas if left in the hands of the same agencies to manage."

#MarineWildlife - The Irish Whale and Dolphin Group (IWDG) has described as "very unusual" a mass stranding of common dolphins on Achill Island last week - which was followed this week by the remains of cetaceans washed up in Kerry.

At least eight common dolphins were found dead on Keel Beach, Keem Beach and Dookinella on the Co Mayo island at the end of January.

And The Irish Times reports that two pilot whales and an "otherwise healthy" dolphin were found washed up at Cuas Croom near Cahirciveen in the last few days.

Commenting on the former incident, IWDG stranding officer Mick O'Connell said: "While there are occasionally live strandings involving groups of dolphins, it is very unusual in this country to see this number of dead dolphins washed ashore over a 10km area."

Strandings of deceased dolphins have also been reported in Donegal, and the IWDG's Simon Berrow suggests that the recent severe weather experienced around Ireland's coast may be a factor.

#MarineWildlife - Sperm whales and a killer whale were among the finds on the last big effort of this year's Cetaceans on the Frontier survey led jointly by the Galway-Mayo Institute of Technology (GMIT) and the Irish Whale and Dolphin Group (IWDG).

As previously reported on Afloat.ie, marine scientists from GMIT's Marine and Freshwater Research Centre are on board the RV Celtic Explorer to carry out the fourth dedicated survey of cetaceans on the continental shelf edge.

The ship was surveying a zig-zag pattern in the Atlantic yesterday 2 February, some 55 nautical miles west-by-northwest of Achill Island (visible on this map HERE) when the team encountered at least two sperm whales, though an elusive third may also have been present - as indicated by the hydrophone being towed 200m behind the vessel.

"The blows continued and as we got closer, more and more body of the surfacing whale could be seen until we were treated to some reasonable views of the steep nose, long flat back and stumpy dorsal fin on initial surfacing followed by a thick tail stock with ‘knuckles’ seen when flaking," writes Niall Keogh on the Cetaceans on the Frontier blog.

Soon after that, the researchers were treated to their first sight of a killer whale in Irish waters - followed by a number of pilot whales surfacing close to the ship.

Photos of the team's finds can be seen HERE.

#MarineWildlife - Here's a little something cheerful to brighten up this chilly, snowy Monday morning: some video footage from YouTube shot by Irish Whale and Dolphin Group (IWDG) member Karl Grabe of the first whales to visit Ireland's shores in 2013.

As previously reported on Afloat.ie, the first sightings were made last week on the maiden member whale-watching trip on board the IWDG's new marine wildlife research vessel Celtic Mist off the coast of Wexford.

In addition to these fin whales, the group also made the acquaintance of a group of frolicking dolphins from the 'superpod' spotted in the Irish Sea recently, as you can see from the clip below:

#MarineWildlife - The whale watching season is well under way off the coast of Wexford, as the Irish Whale and Dolphin Group (IWDG) reported its first sightings of 2013 this week.

Just an hour into the maiden cetacean spotting voyage of the IWDG's new research vessel Celtic Mist at the weekend, members of the group were treated to the sight of fin whales and minke whales feeding south of Hook Head - not to mention some of the 'superpod' of dolphins seen last week in the Irish Sea.

And as World Irish reports, local wildlife ranger Tony Murray spotted the first humpback whale of the year in the same area.

Murray suggested that "a large herring haul going on in the southeast at the moment" is the main attraction for the ocean giants and their smaller, more plentiful companions.

The IWDG's Facebook page has a photo gallery containing some stunning snapshots of the day's excursion HERE.

#MarineWildlife - BBC News has some incredible footage of a 'superpod' comprising hundreds of dolphins in the Irish Sea captured this week.

The video was shot by surprised researchers with the Wales-based Sea Trust on one of the groups routine survey expeditions between Fishguard and Rosslare on board the Stena Europe ferry.

Cliff Benson of the marine wildlife charity described the sea as "boiling" with dolphins just 10 miles off the Irish coast yesterday morning.

"They were just coming and coming. It was the last thing on earth I was expecting in the winter," he said. "We had at least 250 and that's a conservative estimate. I'm guessing there was as many as 500."

The incredible sight comes just a month after the researchers recorded what they called a "dolphin-fest" along the same route west of Tusker Rock, numbering more than a 100 dolphins and 26 porpoises.

BBC News has more on the story HERE - and more footage is available HERE via RTÉ News.

#MarineWildlife - Minister for Arts, Heritage and the Gaeltacht Jimmy Deenihan announced on Wednesday the proposal of six new marine sites for designation as Special Areas of Conservation (SACs) to protect marine habitats and species listed on the 1992 EU Habitats Directive.



The six sites around the Irish coast represent habitats (sandbanks and reefs) and/or marine wildlife (specifically dolphins and porpoises) identified as insufficiently represented in the list of Irish SACs at the EU Commission's Marine Atlantic Biogeographic Seminar in 2009. These sites are:

  • Blackwater Bank, Co Wexford (Sandbank)
  • West Connacht Coast (Bottlenose dolphin)
  • Hempton’s Turbot Bank, Co Donegal (Sandbank)
  • Rockabill to Dalkey Island, Co Dublin (Reefs and harbour porpoise)
  • Porcupine Bank Canyon, off Kerry (Reefs)
  • South-East Rockall Bank (Reefs)


The designation of marine SACs is scheduled for completion in Europe in 2012, and according to the minister, this list of six additional SACs will constitute Ireland’s contribution to that process. 



In a statement, the department said: "These six SAC sites will protect a range of habitats and species including sandbanks, deep sea coral reefs, dolphins off the Atlantic coast and harbour porpoises found in Dublin Bay.

"These sites are part of a European network of nature conservation sites known as Natura 2000 which was established with the aim of preserving our rich natural heritage for future generations."



Among the new designations are two offshore sites at the Porcupine Bank Canyon and the South East Rockall Bank "contain excellent examples of offshore fauna associated with geogenic reef (ie reef made of rock). Considering the extent of Ireland’s offshore maritime area alongside the value and vulnerability of deep sea biodiversity therein, these two sites represent a modest but highly significant contribution to the Irish SAC network."

Two new inshore areas are being proposed in the west of Ireland to protect the bottlenose dolphin. The department is currently co-funding a multi-annual research programme to further understand the ecology of this species in this coastal region.

Meanwhile, the inshore site off Dublin from Rockabill to Dalkey Island is also being proposed both for the harbour porpoise, and for geogenic reef to address a gap in the SAC network for this habitat type in the northern part of the Irish Sea.

As previously reported on Afloat.ie, the oil exploration company behind the Dalkey Island Prospect has spoken out over the Rockabill to Dalkey Island designation, claiming it had not been given advance information of the decision.

Providence Resources says maps provided by the department appear to show and overlap between the location for a seismic survey and the new SAC area, which would make any development for resource extraction "extremely problematic".

Last week the Irish Whale and Dolphin Group (IWDG) expressed concern over the potential impact of the 2D seismic survey at Dalkey Island on harbour porpoises in Dublin Bay.

#MARINE WILDLIFE - Large numbers of dolphins have been filmed in the Irish Sea off the Welsh coast by wildlife volunteers, as WalesOnline reports.

The conservationists with the Sea Trust charity, based in Pembrokeshire, recorded the "dolphin-fest" from the deck of the Stena Europe ferry en route from Fishguard to Rosslare.

Sea Trust director Cliff Benson confirmed the sighting of "a pod of eight Risso's dolphins, 40-plus common dolphins [and] four porpoises" among others as soon as the ferry headed west of Tusker Rock.

Altogether in the three-hour passage across the Irish Sea, the volunteer surveyors recorded a total of 99 common dolphins, 10 Risso's dolphins and 26 harbour porpoises. "That's not bad for a winter trip," said Benson.

He added that while there are threats to the Irish Sea's cetaceans from scallop dredging and the like, "to date our surveys show this area is teeming with life.

“This is Wales and Ireland we are talking about not Bermuda so get this amount of dolphin and porpoise activity with whales thrown in as well is incredible."

Stena has welcomed Sea Trust volunteers on board its vessels since 2004 to check on cetaceans and other marine wildlife in the waters between Ireland and the UK on a monthly basis.

And as reported previously on Afloat.ie, Seatruck Ferries has also been providing free passage to UK marine wildlife researchers to discover how many dolphins and seabirds make their home in the Irish Sea.

Meanwhile, BBC News reports that a pod of more than 100 bottlenose dolphins was recently spotted off the Isle of Man.

The Manx Whale and Dolphin Watch said it received a number of sightings from the east and west coasts of the island in the northern half of the Irish Sea, reporting a hive of activity.

"The group sizes tend to be relatively ginormous," said Tom Felce of the group. "So if they are here you can't miss them."

#MARINE WILDLIFE - Marine researchers off the coast of Donegal were recently treated to a rare dolphin dance by a 50-strong pod, as IrishCentral reports.

The video above captures the same pod witnessed by researchers with the Irish Basking Shark Project, who were in the area off Inishowen to observe basking sharks in the coastal waters when they were surprised by the gregarious dolphin congregation.

A spokesperson for the project confirmed to IrishCentral that such large groupings of dolphins are unusual for the area, which has welcomed more than its fair share of large marine wildlife over recent months.

As previously reported on Afloat.ie, one of the first confirmed sightings of killer whales on the Irish coastline was recorded earlier this summer when a family of orcas from the Scottish Hebrides visited the same waters at the mouth of Lough Swilly.

Meanwhile, WorldIrish reports on the heartwarming tale of a Dutch couple who have bonded with Dingle's most famous non-human resident, Fungie the dolphin.

Jeannine Masset and Rudi Schamhart, who now live in Annascaul, have visited the friendly cetacean for 21 years, and their connection has inspired a fanpage on Facebook that has received responses from Fungie fans around the world.

"Fungie has enriched our lives and we want to give something back to him by offering our friendship and companionship to him," said Jeannine, "and he lets us know over and over again that he really appreciates it."

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.
