#MarineWildlife - The humpback whale known as Boomerang is back – and this time he may have found a mate, according to The Irish Times.

Last spotted almost exactly a year ago off the south coast at the Cork-Waterford border, as previously reported on Afloat.ie, the humpback formally known as HBIRL3 has been spotted by the Irish Whale and Dolphin Group's Andrew Malcolm in recent days in the same location.

But this time he wasn't alone, as another humpback – HBIRL6, a female who last visited Waterford in 2008, and was previously seen with a juvenile off Co Kerry – was keeping him good company. The irish Times has more on the story HERE.

In other cetacean news, the large whale carcass that washed up on Portstewart Strand earlier this month is believed to have died of natural causes.

Originally confirmed as the remains of an adult female sei whale, the 43-foot behemoth has now been identified as a fin whale, most likely a juvenile, as the Belfast Telegraph reports.

Though the cause of death is "inconclusive", it is thought that due to its peeling skin, thin blubber layer and reduced muscle mass, the whale was already dead for days and decomposing before it washed up on the North Coast beach on 4 October.

Fin whales are the second largest mammal in the world's oceans behind only the blue whale.

#MarineWildlife - Check out this wonderful video captured by the Irish Air Corps earlier this week featuring the uncommon sight of a fin whale breaching some 150 miles off Mizen Head in West Cork.

Fin whales, the second largest of the ocean's creatures after the giant blue whale, are a regular sight in Irish waters but are rarely seen breaching here.

According to the Irish Whale and Dolphin Group (IWDG): "The diagnostic white right lower jaw and tall blow confirms this to be a fin whale, although breaching is a behaviour typically associated with other species such as humpback and minke whales.

"There is however evidence that fin whales in the Mediterranean do breach occasionally, so it remains a mystery as to why this behaviour has never before been recorded here."

#MarineWildlife - Achill Island locals have proposed that the 20-metre fin whale beached on Keel Beach over Christmas - and buried just before the New Year - be preserved in some form as a heritage attraction for the region, as the Galway Advertiser reports.

The inspiration comes from the residents of West Cork village Kilbrittain, who were successful in securing permissions to recover the buried remains of a similarly sized whale in 2009. The whale skeleton was since put on display as a big tourism draw.

Similar proposals by Baltimore locals in 2012 after a fin whale became trapped in the town's harbour were scuppered when Cork County Council dumped its remains at sea.

Achill Islander and Irish Whale and Dolphin Group (IWDG) member John O'Shea says that making an attraction out of the whale skeleton would connect people with the area's whaling history, which has changed profoundly over the past century from one of slaughter to preservation.

#MarineWildlife - There's a "fantastic opportunity to witness the second largest animal on the planet close up" on Achill Island over the next few days after a male fin whale was stranded on Keel Beach on Christmas Eve.

The 20-metre-long marine giant live stranded on the beach but died some hours later, as the Irish Whale and Dolphin Group reports. It is as yet unknown what caused the fin whale to strand, but samples of skin, blubber, muscle and baleen have been taken for assessment.

TheJournal.ie repeats Achill Coast Guard's warning for anyone coming to see the whale to stay on the shore and not venture into the surf as the strongest storm in 15 years continues to sweep the country.

#MarineWildlife - Tonight's Nature on One on RTÉ Radio 1 joins the Irish Whale and Dolphin Group (IWDG) on a quest off Hook Head to find the majestic fin whale.

As TEN reports, Colin Stafford Jones was on board with the IEDG's Pádraig Whooley on a mission to track down the world's second largest animal - not only the biggest example of marine wildlife behind the incredible blue whale.

Their adventure will be broadcast tonight (Sunday 9 June) from 7pm on RTÉ Radio 1, and will be available to listen online afterwards via the Nature on One website HERE.

#MARINE WILDLIFE - The carcass of the fin whale that died after being trapped in Baltimore Harbour two months ago has been towed out to sea after its presence in a conservation area attracted complaints.

According to the Irish Examiner, disappointment has been expressed by a local group in Baltimore who hoped to salvage the skeleton of the 65ft female fin whale, the remains of which have now been towed out beyond Fastnet Rock for disposal.

Last week Afloat.ie reported on claims from local resident Tom McCarthy, among others from the Schull area, that the whale carcass was creating a "rancid oil slick" with a "horrendous smell" in Roaringwater Bay, a Special Area of Conservation for marine wildlife that houses a grey seal breeding ground.

However, the Irish Whale and Dolphin Group (IWDG) - which was working with Baltimore residents on their plan to retrieve the bones with a view to displaying the skeleton in the town - criticised the decision by Cork County Council to dump the remains.

IWDG sightings co-ordinator Pádraig Whooley pointed the finger at "vested interests" exaggerating claims about health hazards, arguing that "towing it out to sea raises the very real possibility that [it] could simply wash up on the coast again."

#BALTIMORE WHALE - Nine weeks after the tragic demise of the Baltimore Harbour fin whale, its carcass is still afloat off West Cork, creating a “rancid oil slick” in a special conservation area, according to a local resident.

Tom McCarthy contacted Afloat.ie with the above image of the 65ft whale carcass, which was towed out to the grey seal breeding ground off the Carthys Islands in Roaringwater Bay and has apparently been left to rot.

“It has been left here since the middle of August to decay,” says Tom. “The rancid oil slick is clearly visible and extends for over 1km on relatively still days, the smell is horrendous."

As previously reported on Afloat.ie, plans were afoot to sink the fin whale carcass that was trapped in Baltimore Harbour in mid-August and endured a harrowing few days trapped in Baltimore Harbour before it died from what's presumed to be a combination of illness and injury.

Tom McCarthy claims that the National Parks and Wildlife Service (NPWS) has washed its hands of the situation, considering the enormous marine mammal carcass to be a natural occurrence "even though the animal beached and died several miles [away and] was wrapped in a net and towed to its final resting position".

The location is in a Special Area of Conservation - yet according to Tom, no risk assessment appears to have been carried out beforehand.

"Ten minutes on the internet would show that whales are perhaps the most contaminated animals in the world," he says. "Their blubber is contaminated with persistent organic compounds such as PCBs, DDT, dioxins, etc and the internal organs such as the liver and kidneys are 'high', 'very high' or 'staggeringly high' in mercury, cadmium, chromium, etc.

"Some beached whales are found to be so contaminated the whale itself has to be considered as hazardous waste and disposed of as such."

Tom notes that the area is fished extensively for shrimp, crab, lobster and pollock, and that the rotting carcass is in close proximity to several mussel farms.

"It seems inevitable that as the whale continues to decay and is eaten whatever contaminants were present prior to death will re-enter the food chain."

He compares the current situation to a similar whale carcass disposal in Sligo last year, where the flesh was cut off and sent for incineration while the bones were marked for later skeletal recreation and sent for composting.

Regarding the West Cork whale carcass, Tom says: "Some estimates say it will take three years for the whale to completely decay."

Tom adds that he has been in contact with Cork County Council and hopes to hear on Monday about plans for a more appropriate method of disposal for the whale carcass.

#MARINE WILDLIFE - The Irish Examiner reports that samples from the fin whale that stranded and died in Baltimore Harbour last week have been sent to Dublin for analysis.

Samples of skin and blubber will be tested by marine science experts at the Irish Cetacean Tissue Bank in the Natural History Museum as well as at the Marine Institute, while a student studying for a PhD on the feeding ecology of fin whales will also examine the remains.

As reported yesterday on Afloat.ie, the whale carcass has been towed out of the inner harbour as preparations are made to sink it to the seabed, where marine life such as fish and crabs will quickly strip it down to a skeleton that locals hope to put on display in the West Cork town.

A post-mortem will not be carried out by the Irish Whale and Dolphin Group (IWDG) due to lack of funding for the specialised procedure. A previous necropsy of a fin whale stranded at Courtmacsherry was funded by the US-based magazine National Geographic.

#MARINE WILDLIFE - Plans are afoot to sink the carcass of the fin whale that died after being trapped in Baltimore Harbour last week, according to the Irish Independent.

It is being proposed that the whale's body can be wrapped in netting and sunk using old train wheels as weights.

"We're looking at putting it in the water and letting it sink to the seabed where the fish and crabs can do their work and strip the flesh from the carcass," said local diver Jerry Smith. "The end scenario would be to retrieve the skeleton from the sea bed."

It's hoped that the skeleton of the 65ft female juvenile fin whale could eventually be put on display as an educational aid and a tourist attraction for the West Cork town.

Cork County Council has taken responsibility for the disposal, as the Cork Independent reports, and the 30-tonne marine giant has already been towed to Oldcourt in the Ilen esturary.

As previously reported on Afloat.ie, calls have been made to introduce a new protocol to deal with large marine wildlife strandings.

The Irish Whale and Dolphin Group (IWDG) defended itself from criticism over the handing of the "unprecedented" incident, arguing that allowing the whale to die was the best option available under the circumstances.

#MARINE WILDLIFE - The Cork News reports that a new protocol will be introduced to deal with large marine wildlife strandings following the public backlash over the handling of the injured and malnourished fin whale in Baltimore Harbour this week.

The 30-tonne whale died on Thursday morning after being trapped in the harbour on Tuesday. As previously reported on Afloat.ie, the whale was left to die as it was found to be too ill to be assisted back into deeper water and was too large to be euthanised with drugs.

Members of the public have complained about the 'do nothing' approach taken by experts. But Dr Simon Berrow of the Irish Whale and Dolphin Group (IWDG) defended his organisation's handling of the affair, citing the lack of protocol for such an unforseen incident.

"We are recognised as the most confident group in Ireand in dealing with dolphins and whales but as a charity, it should not be our responsibility," he said. "I don't have the authority to tell someone to shoot a whale."

Dr Berrow said he had been in talks with the Defence Forces about arranging for the distressed whale to be shot before it died, most likely from wounds sustained on sharp rocks in the harbour.

Speaking with The Irish Times, the IWDG's Padraig Whooley said: "As humans, we always think we have to intervene but wildlife rarely does better when we do. In this particular case the ‘do nothing’ approach was the only option open to us."

Whooley also criticised the "fairly shocking" level of ignorance over the incident that saw crowds continue to gather at the harbour in Baltimore even after it became clear that the whale was in significant disgress.

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.
