#Seaweed - Could breathing in the iodine released by seaweed on Ireland's coasts be improving our health?

The answer is quite possibly, according to new research as reported in The Irish Times this week.

Scientists at UCD and NUI Galway have concluded that iodine levels are highest among those regularly breathing coastal air rich in seaweed, which concentrates iodine from seawater.

Their paper in the Irish Medical Journal was informed by two decades of studies in three different environments in Ireland: coastal cities (Dublin, Belfast, Galway), inland areas (Mullingar and Dungannon) and seaweed-rich Carna in Co Galway, where almost half the population has iodine intake above the WHO recommended level.

#CoastalNotes - The rights of coastal communities involved in the likes of small-scale fishing and seaweed harvesting must be respected in any 'Blue Growth' strategy, a UN expert has said.

The Irish Times reports on comments made by UN fisheries chief Dr Rebecca Metzner upon her visit to Galway this week, where she heard the concerns of inshore fishermen who have protested against large-scale fish farming.

Local campaigners breathed relief in December when Bord Iascaigh Mhara (BIM) withdrew its application for what would have been the largest organic salmon farm in Europe, based off the Aran Islands in Galway Bay.

While recognising that aquaculture is required to "fill the gap" in the growing global demand for seafood, Dr Metzner emphasised that dialogue over shared access between local communities and larger commercial interests should be fundamental to any such plans.

She also heard from Connemara seaweed harvesters, who fear the loss of access to the coastline over legislation that may allow harvesting rights to be snapped up by much bigger State-owned enterprises – a situation the Government promised to review two years ago.

#Seaweed - Seaweed cultivation could be a big winner for jobs and the economy, according to a new report by Bord Iascaigh Mhara (BIM).

The Irish Times has more on the report commissioned for a conference held by the Irish sea fisheries board in Limerick yesterday (18 November), which recommends bumping up to commercial farming of two 'brown' seaweeds, Alaria esculenta and Laminaria saccharina, grown in West Cork and Dingle Bay.

That's in addition to targeting high value 'red' seaweeds used as nori in Japanese cuisine - as well as dulse or dilsk, of which Ireland is already the second largest producer.

These are just a tiny fraction of the 500 or so types of seaweed native to Irish waters, and alone could provide for as many as 200 new jobs between farming and processing, according to BIM.

The report comes after seaweed was promoted as the main theme of the Burren Slow Food Expo this summer, with the likes of Darina Allen singing the praises of the versatile foodstuff.

It also comes some months after the Government promised a review of seaweed harvesting rights over concerns along the Connemara coast at growing commercial interest in what's an established traditional coastal community activity.

#islandnation – Having written last week about the lack of national recognition for our maritime heritage I received a press release about the Central Bank honouring John Philip Holland, the Irish inventor of the submarine.

I am pleased to see that the Central Bank has taken such a step but, perusing the media releaseon the Central Bank website, I noted the quote from the Central Bank’s Director of Currency and Facilities Management, Paul Molumby:  “This is the first in a new series that the Central Bank will issue to honour Ireland’s impressive scientific and technological tradition.”

Not a single reference by the Central Bank to the great maritime tradition of Ireland in launching the coin about an invention, fundamental to which was the marine sphere.

Mr.Molumby is quoted further as saying that “John Philip Holland’s life and achievements were extraordinary. He played a significant role in the development of submarine navigation and following his emigration to the USA, he designed the first working submarine.”

Indeed, he did, but Mr.Molumby and the Central Bank omitted mention of the marine in the technological development they were honouring.

At least the Bank went to the Marine Institute in Galway to launch the coin.

The Institute issued a press release with the same quotation, but Dr. Peter Heffernan, the Institute’s CEO, did mention at the launch that Ireland has “a strong tradition of innovation and we at the Marine Institute are very proud to maintain that link with the history of marine technology. We named our remote operated vehicle (ROV) after John Philip Holland.”

This ROV honours the legacy of a man who used the maritime sphere for innovation, but the Central Bank in honouring him do not even use the word ‘marine.’ 

The Marine Institute is using the ROV on surveysof mid-Atlantic volcanic vent fields and new animal communities on the deep canyons of our Continental slope, as well as working on crucial fisheries, environmental and climate changes and assisting in the development of new marine sensor technologies.

The Central Bank is charging €44 for the €15 coin according to the press release.

Am I being tendentious in making this point?

Perhaps, but where there is neglect of the maritime sphere at the highest levels, it should be challenged and the more it is, the more those disregarding our maritime traditions and potential will be forced to change their attitude.

While the issuing of the coin (pictured above) is welcome, I respectfully suggest to the Central Bank that it acknowledge the maritime sphere and note that Holland’s invention relied fundamentally on the marine.

FISH GUTS AND DIESEL AND THE RESTLESS SEA

Have you ever wondered what it’s like to be a fisherman? With Autumn having arrived and Winter not far behind, life on the ocean wave can be tough, rolling and plunging as the boat hits heavy seas while fishermen struggle with lowering and hauling of nets to catch the fish which we can eat in more pleasant surroundings. 

Paul McDonald is a songwriter who wrote much of his work in the heart of Dublin, where he had a cottage in Copper Alley. But he also had experience as a fisherman out of Galway. The song, “Fish Guts and Diesel,” on his CD ‘Crazy Old World’ tells his story of life aboard a trawler many miles out to sea off the West Coast – on the Porcupine Bank. You can hear it on this month’s edition of THIS ISLAND NATION (above), my monthly maritime radio programme that is broadcast on a number of community radio stations.

“As long as I live I’ll never forget the smell of that combination of fish guts and diesel,” he said.

There are some beautiful lines in the song which anyone who has kept a night watch at sea will empathise with:

“Sometimes in the dark as you gaze in the night,

Your mind’s in the stars as your thoughts they take flight

And then a Force Seven brings you back down to earth

And you battle the elements for all that your worth.”

You can hear the song at the start of this month’s programme. As I broadcast it, I could almost see those dead fish eyes which he sings about, staring up at me from the catch hauled aboard. Having been on a few trawlers in my time, occasionally in not-too-pleasant conditions and even though I sail and have sailed in rough weather, I admire hugely those fishermen whose stomachs, I think, must be made of cast-iron to withstand the conditions in which they have to work. I think anyone with an interest in the sea will like the song.

FOREIGN BOATS COST IRELAND OVER A BILLION EUROS

Incidentally, the huge value of fish caught in Irish waters by fleets from France, Spain, Portugal, Holland and the UK, is shown by the figures which the Department of Agriculture, Food and the Marine has released for catches taken last year from around Ireland. The total value was €1.16 billion. That would be hugely valuable to this nation’s economy, but regrettably Ireland’s share of this catch was only 17 per cent in value.  The total catch taken from Irish waters 1,040,117 tonnes, but Irish boats were allowed by EU regulations to catch only 23 per cent of this tonnage. These figures prove just how much the EU gets in monetary value from Ireland. Little is heard about this from economic commentators or politicians who tell us how grateful we should be to the EU, but the reality is that the EU gets a lot of money from Irish waters. Our fishing industry, rather than shrinking in size, should be much bigger, with economic and employment benefit, if the riches of Irish waters had not been given away by Irish governments .Tellingly, the summary line in the figures compiled by the Department says that the economic value of €1.16 billion which they quote for fish caught in Irish waters “… represents a conservative estimate.”

BROADCASTING FROM THE COASTLINE

YOUGHAL_SEAFRONT.jpg

 Youghal seafront

THIS ISLAND NATION is broadcast from the studios of Community Radio Youghal on the coastline of East Cork and the banks of the River Blackwater. I mention on the programme W.M.Nixon’s story about the GP 14 sail up the Blackwater from Youghal, which was reported on Afloat last week. This has raised interest in the sport. The Kathleen and May will be remembered as the great schooner which linked Youghal with the UK and there are many other stories of Youghal seafarers in a town with a great maritime tradition.

Next month, following listener interest, the programme will increase its slot from monthly to fortnightly.

SEAWEED IS NOT JUST A WEED

SEAWEED_GARDENER_MARIE_POWER.jpg

Also on this month’s programme I talk to The Sea Gardener, Marie Power (pictured above), in Tramore. She grew up on what’s known as The Copper Coast of County Waterford, a fascinating part of the countryside and has been running seaweed workshops for several years on a voluntary basis, even though her professional background is in management and training consultancy. Seaweed is not just a weed she says – and she is very definite about that. Listen to hear more.

HALF THE COUNTER IS FARMED

Nearly half of the fish which the public sees on fishmonger’s counters has been farmed. So Richie Flynn, IFA Aquaculture Executive, told me when I interviewed him. “This is something which should be encouraged for the future of coastal communities right around the coast,” he said, but added that the Government’s attitude towards licensing “is still a problem for aquaculture development.”

#Seaweed - Minister of State Kathleen Lynch has promised to review legislation pertaining to right for harvesting seaweed in Connemara over recent local concerns over commercial interests in the region.

As previously reported on Afloat.ie, coastal communities north of Galway Bay fear their rights to the traditional activity would be threatened by allowing larger businesses - such as the State-owned Arramara Teoranta - to move in.

Now Galway Bay FM reports that the Department of Environment has admitted there is a conflict between the Foreshore Act and the rights of private landowners on the coastline. More on the story HERE.

#Seaweed - Galway Bay FM reports on some consternation over a new licensing regime for seaweed harvesting in Connemara to the north of Galway Bay.

Harvesting seaweed is an established tradition among coastal communities in the region, but locals fear their activity will be threatened by allowing larger businesses to move in.

Two public meetings have taken place this week to discuss the implications of various companies applying to the Department of the Marine for harvesting licenses - one of which, the State-owned Arramara Teoranta, wants rights on the coastline from Connemara to West Mayo.

#Tourism - How's this for a unique winter break in Ireland - a visit to a century-old seaweed bathhouse in Sligo, anyone?

That's what Guardian writer Nick Fisher did recently when he and his family spent a week in the north-west to partake of Kilcullen's Seaweed Baths, right next to the shore at Enniscrone beach.

Angling is the big tourism draw for the region, now that the salmon season is well underway, with the River Moy providing all the sport a caster could want at any level.

But it's the seaweed baths - fed with water and fresh seaweed from Enniscrone Bay - that put a unique stamp on the whole experience, according to Fisher.

"People with skin conditions... as well as sportsmen and women love these baths," he writes. "Many of the local pensioners have season tickets ('To warm their old bones in the winters') and I'm told it is a very popular hangover cure.

"After the hot silky seaweed soak, the stinging, cleansing, pins-and-needles of the cold seawater shower leaves a bather feeling newly minted."

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.
