#BowheadWhale - The search continues in tracking down the elusive bowhead whale that's excited marine wildlife experts since it was sighted in Carlingford Lough at the weekend.

One of a species never before recorded in Irish waters in the 25 years since the Irish Whale and Dolphin Group (IWDG) was formed, the 20ft juvenile whale was photographed from a pilot boat at the mouth of the lough at the Helly Hunter Rocks on Sunday 29 May.

It's thought that it may be the same individual from the arctic species spotted off Cornwall in mid May, following a previous bowhead sighting at the Scilly Isles in February.

The Celtic Mist joined the hunt yesterday (Tuesday 31 May) on its circumnavigation of Ireland and failed to make any sighting, though bowhead whales are known for being difficult to spot due to their lack of a dorsal fin.

The IWDG has much more on this story HERE.

#MarineWildlife - Places are going fast for a special cruise on board the Irish Whale and Dolphin Group's Celtic Mist to celebrate the 25th anniversary of Ireland's whale and dolphin sanctuary.

Celtic Mist will depart Fenit, Co Kerry next Saturday 7 May with a team of IWDG members and marine science experts on an almost three-month circumnavigation of Ireland, first heading north along the Wild Atlantic Way and around to the Irish Sea, calling on Dublin on 7 June to mark the 25th anniversary of the Irish Government's official declaration of this island's waters as a sanctuary for cetaceans.

The declaration came only three months after it was proposed by the then newly formed IWDG, and both have been instrumental in raising awareness of the bounty of marine wildlife in Irish waters.

Though berths on the voyage are filling fast, everyone will have the opportunity to participate by assisting in outreach events along the cruise route, or by tracking its progress online. Details on how to get involved can be found on the IWDG website HERE.

Along the way passengers on Celtic Mist may be treated to some of the incredible wildlife the sanctuary was created to protect, such as humpback whales – a number of which were spotted on an early visit to West Kerry earlier this month, likely attracted by schools of sand eels, as the IWDG reports.

In other marine wildlife news, locals near a beach close to Ballyshannon in Co Donegal have complained after a whale carcass was left rotting on rocks three days after it was reported to authorities.

According to the Irish Mirror, successive high tides had failed to shift the 25ft minke whale, though Donegal County Council says it is arranging for the animal's disposal.

#BaskingSharks - Conservationist Andrew Power was in the right place at the right time on Monday morning (11 April) when he witnessed a group of up to 20 basking sharks feeding off Kilkee, Co Clare.

"You could see the inside of their huge mouths very clearly under the water as they were feeding," Power told RTÉ News of the three-hour breakfast. "They swam close to the rocks going in circles. It was incredible."



The Irish Whale and Dolphin Group (IWDG) reports that another sighting was made at the same time off Slea Head in Co Kerry – adding to a list of inshore sightings along the South West coast since 31 March, when the first basking shark spotting of 2016 was reported off West Cork.

Regular visitors to our shores, the second largest fish in the ocean were last seen in numbers back in September, as previously reported on Afloat.ie.

And the sheer size of this group is surely a boost for the 'shark park' initiative mooted for the Wild Atlantic Way last summer.

#MarineWildlife - Whale sightings are on the increase in the South East this week as the season tapers off, according to the Irish Whale and Dolphin Group (IWDG).

"As large whales don't keep to our calendar year, this annual south east flurry of large whale sightings represents the tail-end our our large whale season," says the IWDG's sightings officer Pádraig Whooley.

"And what a season it has been, especially for the humpback whale, which have enjoyed a record year both in terms of frequency of sightings since they first appeared in early May off the Slea Head Peninsula."

The latest spots were made both on land – by Andrew Malcolm and Ann Trimble from Ardmore Co in Waterford at the weekend – and on a whale-watching trip with Martin Colfer's South Coast Charter Angling, recording a humpback whale and more than five fin whales between them.

And there might still be time to head down to the Sunny South East to catch a glimpse of these ocean giants before they depart for the spring.

Voyages out as far as the edge of the Continental Shelf on the Atlantic Ocean has produced rare sightings for the Irish Whale and Dolphin Group and this August there is a chance to see the join the crew and see the whales again writes Patrick Lyne

Back in 2012 when the Celtic Mist became available to the Irish Whale and Dolphin Group we were looking at ways the boat could be used to support the work the Group does and demonstrate to people in Ireland the wealth of life that exists in Irish waters. So for three years from 2012 to 2014 we took the Celtic Mist to the shelf edge in early September. Indeed we were blessed when first arriving on the shelf edge only to be greeted by two blue whales. It took several minutes in close proximity (200m) to the whales before we believed our eyes. We had expected large whales but not those to be waiting for us. They stayed around and passed either side of the boat moving from port to starboard for what seemed like an age, before moving further away. We could manage a top speed of maybe 8 knots while blue whales could travel at up to 25 knots approximately and there was no way we could keep pace with these animals if they decided to leave us behind.

Shortly afterwards the Irish Air Corps Casa (C253) appeared and called on the radio and managed to get some excellent shots of both the Celtic Mist and the blue whales.

In 2013 had some remarkable sightings of beaked whales again in the Porcupine Seabight and while unable to confirm that the animals that passed close to the vessel in 2013, were True’s beaked whales, it seems highly probable that they were. Beaked whales are particularly difficult to study being adverse to noise and spending large periods of time underwater. The Cuvier’s beaked whale holds the record for the longest recorded dive of any cetacean of 2 hours 17 minutes while attaining a depth of 2,992m. These animals are rarely seen close to shore and when they are, they often end up stranding and dying. The deep ocean off the shelf edge is their natural habitat.

Each year has produced it’s own spectcular moments and the humpback whales off Dingle have become more and more reliable and are a feature of our trips every year. Last year we were treated to one beautiful day on the shelf edge with calm weather. It is this calm weather that always produces the best results. While whales numbers wer not spectacular they were considerable and most if not all animals were engaged in feeding. We simply allowed the boat to drift while fin whales fed in close proimity to the boat and we could see the huge jaws opening to envelope the krill underwater.

Last year we changed vessels to Jessy of Adrigole a 37 ft–yacht, the Celtic Mist being unavailable and this year we have decided to continue using Jessy but for a longer trip. We propose starting in Castletownbere and sailing to Camaret in Brittany along the shelf edge. The shelf edge between here and Brittany is some of the most dramatic in the world with drop offs from 200m down to nearly 4000m. The EEZ of the UK is slowly squeezed such that French and Irish waters will eventually meet as boundaries extend.

It is more important than ever to record the variety and abundance of Ireland’s offshore environment. While oil exploration will suffer from the current over supply, exploration rights has been granted to both Russia and France by the International Seabed Authority (ISA – not the Irish Sailing Association but a UN body based in Jamaica) in the mid-Atlantic Ridge in the North Atlantic. The marine environment is constantly under greater and greater pressure. Protection for cetaceans is critical to mainting the entire marine habitat. Reduction in large whale numbers in the Southern Ocean due to whaling did not result in an increase in their favourite prey, krill, but rather reduced krill abundance. Whale faeces enriches the ocean with iron, producing plankton blooms which start the food chain and absorb excess carbon from the atmosphere. The South West in particualr sees large numbers of tuna arrive in August and September, follwoed by French and Spanish and Irish fishing vessel as well as whales. It is important for the whales that they are able to build blubber reserves at this time, especially for the females as without sufficient reserves to sustain them during pregnancy of 11 or 12 months, the whale will abort. Recovery rates are slow with these large whales and even with protection it will be manay many decades before fin and blue whale numbers reach pre-whaling levels.

In August we will embark again to try and find calm weather on the shelf edge and hope to add significantly to the picture of cetaceans in Irish waters in a time when they are at their most abundant. It is a unique opportunity for people to become involved with our marine mega fauna in a way not available elsewhere and to add to knowledge of the area. The charge to crew of €1310 allows the work to take place and is an enriching experience and an education. If interested contact Patrick Lyne by email ([email protected]).

#MarineWildlife - A research paper produced in a joint project by the Irish Whale and Dolphin Group (IWDG) and the Galway-Mayo Institute of Technology (GMIT) was cited by an expert panel that has struck down Japan's plans to resume whaling in the Southern Ocean.

As the Guardian reports, the International Whaling Committee (IWC) panel said Japan's revised programme did to have enough detail to determine whether it needed to hunt whales in order to, as per its reasons, measure population sizes ahead of any return to commercial whaling, or gain "a better understanding of the Antarctic marine ecosystem".

"The current proposal does not demonstrate the need for lethal sampling to achieve those objectives," said the IWC experts' report.

The IWDG-GMIT paper lead authored by Dr Conor Ryan and published in Marine Ecology Progress Series in 2013, which details the collection of relevant data from live biopsy tissue samples, was cited by the experts as evidence contrary to Japan's assertions.

Japan was forced to revise its whaling programme in the face of controversy last year after the International Court of Justice ruled it was not whaling for scientific research purposes.

The IWDG says that the IWC's report "endorses the internationally significant work being carried out in Ireland and shows how this information can be used to inform important management decisions such as that offered by the IWC Expert Panel."

Other recent research work conducted by the IWDG includes a visual and acoustic survey of cetaceans during the annual Marine Institute bus whiting survey, and a review of the National Parks and Wildlife Service's National Cetacean Protection Strategy.

#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.

#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.
