#MarineWildlife - Concerns have been raised over the levels of plastic pollution at an important gannet colony on the smallest of the Skellig Islands.

As The Irish Times reports, discarded plastic waste – including parts of old fishing gear in the Atlantic for more than a decade – now comprises a large proportion of the material used by some 70,000 gannets to build their nests on Little Skellig.

And conservationists fear the problem is being ignored by authorities focused on marketing nearby Skellig Michael to tourists based on it appearance in recent Star Wars films.

“I film marine life underwater [and] it’s very difficult to get a frame without plastic in it, and that wasn’t an issue 15 years ago,” said local filmmaker Vincent Hyland, who added that plastic pollution levels had reached “frightening proportions” in the last year.

Sinn Féin MEP Liadh Ní Riada has warned there will be more plastic waste in our oceans than fish by 2050, according to a UN report.

The Ireland South MEP gave the stark warning as she addressed the European Parliament on the urgent need to tackle plastic pollution.

Ms Ní Riada, who sits on the EU Fisheries Committee, said we all had to take responsibility for the problem, citing Ireland as one of the worst polluting offenders.

“Plastic pollution is affecting marine life in even the most remote parts of the Atlantic Ocean,” she said.

“Almost three quarters of a sample of more than 230 deep water fish collected by NUI Galway scientists had ingested plastic particles.

“However, it's important we recognise that it is not the fisheries that are solely responsible for this but they are part of the answer. Indeed, fisheries were, in my view, the first environmentalists; they had to be in order to maintain and sustain a living.

“We have to tackle this issue now, as a matter of urgency. Already we have seen reports predicting that there will be more plastic waste than fish in our oceans by 2050.

“To treat this as anything other than an emergency is to condemn future generations to dying oceans and a corrupted environment.

“The issue, like the oceans it's affecting, can seem so vast that it is beyond our ability to act but there are practical solutions that we can apply.

“Education, for example, is key in this and the Polluter Pays Principle has to come into effect.

“Manufacturers must take responsibility and ownership of the fact that they are producing these vast amounts of plastic, be it nets or be it in the ordinary every day use of things like plastic bottles.

“We all use plastic on so many different levels and we all have to be individually responsible for our own use but if we are to begin undoing the damage that we have cause to our oceans then manufacturers must play a key role.

“Looking at the extension of initiatives such as the Litter Scheme may also help. Incentivising fisheries to grab in the ghost nets is a positive move but we should examine extending that a bit further and invest more in our fisheries to try and incentivise them to gather up plastic as they're fishing.

“We also need to look at plastic recycling and how that feeds into the circular economy.

“There are many positive things in today's report. I look forward to examining it and putting forward some of my own amendments.

“But let there be no doubt about how big this issue is and how crucial it is that we all accept our responsibility in having contributed to it.

“For example, I'm ashamed to say that Ireland is one of the top polluters and that's not a record that we're proud of.

“As an Irish person, as an Irish MEP I am more than willing to get stuck into this issue to see can we tackle it once and for all, both the existing problem and the future problems that its going to cause.”

#DublinBay - Litter in the water is a longstanding issue in Dun Laoghaire and Sandycove — but one local schoolgirl has taken it upon herself to do something about it.

Ten-year-old Flossie Donnelly started this past summer calling for volunteers to help clean up the sea shore at Sandycove every Friday evening, even designing her own poster to spread the word on social media and around the neighbourhood.

On her blog, Flossie writes that she was “really sad” that no one came to her first clean-up.

But a meeting at the Forty Foot the next day with county councillor Cormac Devlin led to the word spreading further in the local press.

“It’s very unusual that a child of her age approached an adult and a politician at that. That she is so environmentally aware is wonderful,” Cllr Devlin told the Dublin People in August.

By the end of the summer, Flossie was in charge of her own crew of volunteers helping to remove plastic debris that is dangerous to Dublin Bay’s marine life and local boaters alike.

Despite the shorter days and colder weather of late autumn and winter, Flossie is still leading regular coastal clean-ups and making friends along the way — including an Australian girl whose message she found in a bottle.

More recently, Flossie was out on a RIB in Dun Laoghaire Harbour to clean up the breakwaters — filling three boats with rubbish and doing “a week’s work in a day”, according to Dun Laoghaire Coast Guard, who praised the “inspirational” girl for her efforts.

But the ambitious youngster isn’t stopping there, with plans to raise money for the installation of a Seabin automated cleaning system for the harbour, in what would be a first for Ireland.

Previously highlighted during Afloat.ie’s Rio Olympics coverage last year, the Seabin device has the potential to collect as many as 83,000 plastic bags or 20,000 plastic bottles each year.

That amounts to half a tonne of plastic annually, from visible debris to micro-plastics that threaten our protected species.

Britain’s first Seabin was recently installed at the pontoon of America’s Cup team Land Rover BAR in Portsmouth as part of a project to restore populations of oysters in the Solent.

Flossie and her beach cleaning squad will be hosting a table quiz at Fitzgerald’s Pub in Sandycove next Thursday 30 November to raise funds towards Dublin Bay’s first Seabin. For details see Flossie’s website HERE.

The EU should review the materials used in plastic bag manufacture and encourage greater usage of biodegradable carrier bags to prevent further marine environmental damage, according to Jim Higgins MEP, following a vote by the European Parliament on the issue this week.

This week, MEPs backed ambitious targets which will oblige Member States to reduce their use of light plastic bags, first by half, and then up to 80 per cent as compared to the average EU consumption in 2010 within at least 5 years.

This is good news for the marine environment according to MEP Higgins: "60-80 per cent of all marine litter is plastic material, scattered across all the world's oceans. The seabed closest to coastal regions can be most contaminated, especially with debris from carrier bags.

"The sheer volume of plastic waste and its durability is causing havoc for marine life which gets entangled in it or ingests the debris. There is also some evidence to suggest that chemicals from the materials present a toxic hazard for marine life and seawater quality.

"The durability and hard-wearing nature of plastic that makes it so useful also makes it problematic for environmental reasons as it takes so long to degrade. While some initiatives to reduce our reliance on plastic and increase recycling are positive, such as the plastic bag charge and more reusable shopping bags, we need to review the actual materials being used by manufacturers," Mr Higgins continued.

"An in-depth study by the University of Plymouth on the degradation of plastic carrier bags in a realistic marine environment showed that compostable plastic disappeared between 16-24 weeks, whereas 98 per cent of all other plastic remained after 40 weeks. One possible remedy proposed by the scientists behind the study is increasing our use of biodegradable carrier bags."

The Midlands North West MEP highlighted a recent success story in Italy: "Thanks to the use of biodegradable-compostable bags combined with a restriction of other types of bags, Italy has halved its plastic bag consumption since 2011. This is a trend that could apply to the entire EU under the right conditions."

#MarineScience - A green cleaning brand plans to use science to recycle plastic waste from the sea in the production of a new type of sustainable plastic bottle.

The Guardian reports that Belgian firm Ecover is working with plastic manufacturer Logoplaste to combine plastic taken from the sea with recycled plastic and a type of plastic made from sugar cane known as Plantastic.

Chief executive Philip Malmberg said: "We won't have a definitive figure on the amount we will retrieve, we are just hoping to get as much as is possible and give fishermen an incentive to join the initiative and help clean the seas."

Plastic waste accounts for almost 60% of all litter on Britain's beaches, according to stats from the Marine Conservation Society - and can also cause great harm to marine wildlife, after recent reports that a sperm whale washed up dead in Spain had swallowed 17kg of plastic waste dumped by farmers growing vegetables for UK supermarkets.

It's hoped that boats can be outfitted with special equipment that will allow them to collect up to eight tonnes of plastic waste for recycling - and that fishermen can deposit any plastic they collect at designated points.

Taking my grandson to school in Crosshaven he showed me a page of homework which his teacher had said they would be talking about in class. It demonstrated the effect of debris on the oceans and what can happen when litter is thrown into a river or stream or left on the beach.

It was very topical, because this week the Fifth International Marine Debris Conference is taking place in Hawaii, organised jointly by the National Oceanic and Atmospheric Administration and the United Nations Environment Programme. This is an attempt to deal with the increasing problem of debris in the oceans of the world.

A United Nations report revealed some pretty frightening facts to the conference. Just two kinds of rubbish make up more than half the marine debris in the world. One is predictable enough – the horror of plastic choking sea life. The other came as more of a shock. The second most abundant kind of marine litter is smoking-related. Cigarette butts and packing account for nearly half of all sea rubbish in some parts of the world, according to the UN.

About 40 per cent of the litter in the Mediterranean Sea comes from this source. In Ecuador, smoking-related refuse accounted for more than half of coastal rubbish.

Ocean debris is a severe threat to the marine eco system. It kills at least 1 million sea birds and 100, 000 mammals each year, according to the United States National Oceanic and Atmospheric Association. The general prognosis at the conference in Hawaii has been pretty grim. Things are getting worse and it is the fault of humans on land using the oceans as rubbish dumps.

As my grandson's homework showed, it takes two weeks for a bit of fruit thrown into a river or the sea to bio-degrade. It will be two months before a piece of cardboard breaks down, three months for a milk carton and matters get worse where a cigarette butt is concerned. That will take ten years to disintegrate, a Styrofoam coffee cup 50 years, a plastic bag over a hundred and the six-pack ring so often tossed overboard from boats 400 years, with the plastic bottle even worse at 450 years.

The threat and impact of marine debris have long been ignored. Perhaps it is the perceived vastness of the ocean and lack of visibility of marine debris, but the teachers in Crosshaven national school, on the edge of Cork Harbour deserve praise for making their young pupils aware of what throwing litter into a river or dumping it on a beach does.

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.
