#MarineWildlife - The Irish Sea is providing plenty of big game for sea angling enthusiasts as of late, with impressively sized porbeagle sharks among the recent catches.

As Angling Times reports, Dutch angler Robin Van Da Meer reeled in a 300lb beast off the Antrim Coast just days after Bangor man Brian Menary landed a 360lb specimen from the same boat, Predator 2, out of Red Bay.

But that's just the tip of the iceberg, as Wirral News remarks on the "flurry of exciting wildlife sightings" from the British side of the Irish Sea.

Experts say the warm weather that has mostly persisted since the end of the summer is largely responsible for the increase in sightings of such rare visitors as leatherback turtles, and the enormous ocean sunfish – two of which have been seen outside their usual haunts off the south of England.

According to Emily Baxter of the North West Wildlife Trusts, keen spotters on the Irish Sea coast – or even ferries crossing back and forth – "could be in for an exciting end to the summer".

#RNLI - Lifeboat volunteer crewmembers with Douglas RNLI on the Isle of Man were paged at 9.24pm on Thursday evening (11 September) to a report of a person in the Irish Sea off Victoria Pier.

The all-weather lifeboat Sir William Hillary was launched under the command of coxswain Neal Corran, who proceeded to the seaward side of the Victoria Pier where the person was successfully located.

The casualty was recovered to the lifeboat and taken immediately to the Liner Berth inside the harbour to a waiting ambulance.

The lifeboat then returned to the boathouse to be washed down, re-fuelled and was ready again for service at 10.15pm.

#Fishing - Salmon and cod numbers in the Irish Sea have continued to decline despite strict fishing and angling controls, according to BBC News.

The "rather poor" forecast for the important fish species comes from data collected by the Agri-Food and Biosciences Institute (AFBI) via its research vessel The Corystes, which sails the Irish Sea over 200 days a year and sets the standard for EU fishing quotas.

The AFBI's Walter Crozier said stocks had not "bounced back in the way that scientists expected. So we're now looking at other explanations because there isn't much more the fishing industry can do to reduce their catch of cod in the Irish Sea."

Such factors may include climate change causing a rise in sea temperatures, and increasing diversity of the marine ecosystem.

#IrishSea - One million cubic metres of radioactive waste at a dump site near Sellafield is at risk of contaminating the Irish Sea in the future, according to papers released by Britain's Environment Agency.

According to The Guardian, the internal report says it is "doubtful" whether the location of the Drigg Low-Level Waste Repository (LLWR) on the Cumbrian coast "would be chosen for a new facility for near-surface radioactive waste disposal if the choice were being made now."

Though the full effects of coastal erosion, weathering and flooding are not expected to be felt until "a few hundred to a few thousand years from now", the agency has expressed worry over the site's gradual exposure to the elements.

This is compounded by fears that past deposits at the site over the last 55 years have included higher-level radioactive waste than intended.

#coastguard – A vessel that first reported suffering steering problems off the south west of Scotland early this afternoon has now been found and towed to safety.
Liverpool Coastguard received a 999 call from one of the two people on board the vessel just after 1pm this afternoon, reporting they were having mechanical problems. They said they were was just south of Burrow Head, having set off from Oban and heading to Liverpool.
The Ramsey RNLI all-weather lifeboat was sent to the scene, but they could not track down the vessel. Liverpool Coastguard managed to get hold of those on board again and soon established they were in a different position near the Cumbrian coast. The Workington RNLI all-weather lifeboat joined the search, but again on arrival at this new position there was no sign of the vessel.
Further contact was made with the two on board the boat, who were told to set off their distress flares. These weren't spotted by those on scene. In light of the approaching darkness and misty conditions, the Whitehaven and Maryport Coastguard Rescue Teams were sent to carry out harbour and coastal searches. The search and rescue helicopter from RAF Valley was also sent to join in the search and a mayday relay broadcast was made asking for any other boats to report sightings.
The helicopter from RAF Valley finally located the vessel just before 6pm this evening off Harrington, Cumbria. The boat was then towed into Workington harbour and met by the Maryport Coastguard Rescue Team.
Lucy Hicks, Watch Manager at Liverpool Coastguard, said:
"This was a difficult rescue as we did not have the exact location of this vessel. They didn't have a VHF radio on board or an emergency beacon which could have sent a more accurate position of where they were.
"An extensive search continued for a number of hours, and with darkness fast approaching along with deteriorating weather conditions, we needed to find this boat. Luckily, they were spotted by the search and rescue helicopter and then taken to safety.
"We always recommend that boats are well equipped with all the necessary communications and navigation equipment on board. It's also useful to have an Emergency Position Indicating Radio Beacon (EPIRB) or a Personal Locator Beacon (PLB) with you, which can send an accurate position of where you are to the Coastguard."

#MarineWildlife - Five Risso's dolphin calves spotted by researchers off the Isle of Man this summer point to the waters of the Irish Sea as a breeding ground for the gregarious marine mammals.

As BBC News reports, the five calves were seen north of the Calf of Man at the end of July.

And according to a spokesperson for the Manx Whale and Dolphin Watch: "It means Manx waters must be important to the breeding population of Risso's dolphins in the Irish Sea."

The waters between the east coast of Ireland and north-west England and Wales are known to be teeming with dolphins of different species, with video of a dolphin 'superpod' wowing ferry-goers earlier this year.

#isora – Under not ideal weather and sea conditions yesterday's final ISORA race of 2013 was a battle of gargantuan proportions between the Series leader "Ruth" and close second "Sgrech". The two J109's, with "Sgrech" only giving 43 seconds in the expected 12 hour race "Ruth" writes ISORA chairman, Peter Ryan.

After a long season with many boats having races and sailed thousands of miles. With some boats with gear problems and others with crew fatigue after three consecutive weekends of offshore racing, only 13 boats out of an entry list of 22 came to the start line in Pwllheli. The PSC starter Richard Tudor sent the fleet of on a direct course from the start to the finish in Dun Laoghaire.

The weather forecast appeared to be very manageable with the winds of maximum 25 knots, north west backing south west over the day. Unfortunately the north west wind had been blowing strong for all the previous day producing overall conditions at Bardsey that were not pleasant. The first leg to Tudwals was a tight reach. After the warning signal "Sgrech" and "Ruth" commenced manouvers to get the better start. The two boats headed off in front of the fleet within a boat length of each other towards Tusdal's sound.

In Tudwal's sound more tussles arose between the tow boats in the form of a luffing match. This facilitate "Pipedreamer 6", "Mojito" and "Lula Belle" to pass them into the lead. Sea condition past Tudwal's sound warned of what was going to be met at Bardsey. It was a beat to Bardsey. While most of the fleet chose to go through the sound with the north going tide some boats including "Sarnia" ventured outside the island. The five lead boats arrived at Bardsey close together with "Ruth" and "Sgrech" exchanging tacks.

Conditions at Bardsey Sound were "pretty bad"!!!!. Huge and breaking seas met those who ventured through. "Sgrech" recorded a ground speed of 14.2k at one stage. "Windshift" suffered some slight gear damage with the pounding and retired. At the same time the life raft on "Sgrech" broke its fixings and was heading off the stern before the crew managed to retrieve it. "Poppy of Brighton" had retired earlier.

Exiting Bardsey "Ruth" and "Sgrech" were still within boats lengths of each other and leading the fleet with "Mojito" close behind and headed off north on a beat in the north going tide. The wind was still north west. Over the following few hours, the backing wind lifted the boats on the north leg of the beat to arrive north of the Bailey lighthouse. At all time "Ruth" and "Sgrech" were within 100m of each other with the boast being side by side "Ruth" being to weather. Felloe J109 "Mojito" was close behind.

It was only just approaching the Kish Light that "Sgrech" regained the advantage and set the scene of the tacking duel between the two boats across Dublin Bay to the finish at Dun Laoghaire Pier heads. "Sgrech" held the lead and finished just 1 minute 50 seconds ahead of "Ruth". "Mojito" finished approximately 10 minutes behind the leaders to give the J109's a 1st, 2nd and 3rd place overall and Class 1. "Sarnia", the oldest and lowest rated boat in the fleet took Class 2 and Silver Class Overall with "Lula Belle" taking 2nd Class 2 and "Yahtzee" taking 3rd Class 2 and 2nd Silver Class while Sigma 33 "Polished Manx" took 3rd Silver Class.

The result of the gargantuan battle between "Ruth" and "Sgrech" was that "Sgrech" retained the ISORA lynx metmAsts Offshore Series 2013 champion status, ahead of "Ruth". "Polished Manx" is the ISORA lynx metmAsts Offshore Silver Series 2013 champion. Full details are below.

The usual "dignified" end of series party took place in the NYC immediately after the race.

The progress of the race was recorded using the PredictWind tracker but some boats had technical problems. It can be viewed on the iPhone or smartphone app or on the website at http://forecast.predictwind.com/tracking/race/ISORA It is hoped to make the use of this tracker as mandatory for next years races however this will be discussed at the ISORA AGM in the NYC on the 16th November.

The prize giving will take place at the ISORA annual dinner to be held in the NYC on the 16th November. To avoid disappointment, it is vital that places are booked early with the club.

It was a fitting and exciting end to a very success offshore series where, with the possible exception of yesterday's race, all the races were sailed in great racing conditions. It is hoped that this close racing will attract new boats to enter and race "outside of the Bay".

#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.

#Kayaking - Derry Mayor Martin Reilly offered his congratulations to native son Jake King on taking the surf kayak world title in Australia earlier this month.

As the Derry Journal reports, 18-year-old King was crowned champion after topping three other reigning top dogs in the men's longboat, masters and junior short boat in the final of the competition at Maroochydore beach in Queensland.

According to his father Paddy, Jake King can now add his name to the list of five previous world champions from the Canoe Association of Northern Ireland (CANI) surf kayak club - which includes his brother Corin.

In other kayaking news, a London paddler has broken the record for circumnavigating the Isle of Man in the Irish Sea.

BBC News reports on the feat achieved by 39-year-old George Shaw, who completed the 115km route around the island in 11 hours 43 minutes - smashing the previous record by almost an hour.

#MarineWildlife - BBC News reports that whale watchers in the Isle of Man have spotted the first humpback whale in the waters around the island since 2010.

Tom Felce of Manx Whale and Dolphin Watch confirmed the "very rare" sighting in the Irish Sea two miles south of Castletown last week.

It's an unusual location to spot one of these ocean giants, who are a regular sight off West Cork - but even cetacean spotters there have been surprised by changes in their activity as of late.

The west coasts of Ireland and Scotland lie in the humpback's usual migratory path from the cold polar waters where it feeds in summer to subtropical climes off North Africa where it breeds in winter.

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.
