#Rio2016 - Antimicrobial suits could be an answer to Rio 2016's pollution issues. But are they all they're cracked up to be?

Headlines have made much of the microbe-resistant properties of the new costumes designed for the US Olympic rowing team, as Ars Technica reports.

Comprising two layers, one to wick water from the skin and the other with an antimicrobial finish, the fabric is being talked up for its properties of protection against the water-borne pathogens in Guanabara Bay and the Rodrigo de Freitas lagoon – the latter where rowers will compete next month.

But the textile engineer behind the design says any such claims are "overblown".

Speaking to Vocativ, Mark Sunderland of Philadelphia University confirmed that the antimicrobial finish was an "afterthought" and comparable to athletic wear already on the high street.

Indeed, the primary benefit to rowers is the suit's seamless fit, covering less than half of the body – designed for comfort in high-performance conditions, not for health reasons.

#Rio2016 - Olympics organisers in Rio have a new headache alongside Zika concerns and rising crime – the city's sailing waters are turning boats brown.



After Chilean 49erFX squad Team Gumucio posted the above video to Facebook, further reports have emerged of sailors getting caught in an oil slick on Guanabara Bay.

"We've never seen anything like this. It was all over the place," Finnish sailor Camilla Cedercreutz told the Associated Press after the slick stained the white hull of her boat brown.

It appears sailors training in Rio's waters ahead of next month's Games now have to add industrial pollution to their list of issues with the Olympic aquatic venue on top of floating debris and high levels of pathogens.

#Fishing - 'Money for old rope' is the pitch for a new initiative that aims to recycle old fishing nets that often end up littering the seas, as the Irish Examiner reports.

A number of Irish companies have been invited to Norway later this year to explore the possibility of collecting abandoned fishing nets and other ocean waste for repurposing in various industries – such as using the rope fibres in reinforced concrete.

They will be led by Macroom E, a company started by Cork County Council to help small and medium businesses make the most of recycling initiatives.

Macroom E is a partner with Circular Ocean, a Europe-wide project hosting a showcase this September on its work to remove waste from the ocean – where plastic and 'ghost nets' remain a hazard to marine wildlife – and turn it into a useful, and profitable, resource.

#Larne - Coastal wildlife in Co Antrim is under threat after a significant diesel spill from a Caterpillar plant in Larne at the weekend, as the News Letter reports.

The plant machinery firm faces likely enforcement action after 40,000 litres of red diesel leaked into Larne Lough via a storm drain – news of which was not made public till days later, according to the Belfast Telegraph.

As the Northern Ireland Environment Agency moved to assure that the spill's impact on marine life would be minimal, conservationists remain concerned as the diesel slick was seen drifting towards The Gobbins, home to many protected seabird species.

Spot checks of affected parts of the Antrim coast have as yet found no injured birds, but Ulster Wildlife maintains that the spill "could have potentially devastating impacts on breeding birds".

#Pollution - Inland Fisheries Ireland (IFI) has issued an appeal to all farmers to be vigilant when harvesting silage and spreading slurry to avoid water pollution.

Silage operations are ongoing all summer and silage effluent has the potential to cause devastating pollution in streams and rivers. Silage effluent is one of the most polluting substances to threaten the environment and can cause massive fish kills if it enters a watercourse.

Slurry spread on grassland over the summer months can also wipe out fish and invertebrate life if allowed to enter a stream. Water levels in streams and rivers are low in the summer months and have less dilution capacity, so are particularly vulnerable to pollution at this time.

“The fisheries service is appealing to all farmers and contractors to be careful that no silage effluent is allowed to run off into drains or watercourses," said Dr Greg Forde, head of operations at IFI.

"Round bales are the most environmentally friendly way to store silage. However, if a silage pit is used, it must be properly lined to prevent leakage.

“Good farmyard management will help to prevent accidental run-off and protect the local environment. Slurry spreading should only be carried out in dry weather, and not when heavy rain is forecast. It should never be spread close to a watercourse, and tanks should never be cleaned beside a stream or river.

Dr Forde addd that IFI “is grateful to the farming community for its co-operation at this busy time of year, and for its assistance in maintaining a clean and healthy environment in our lakes and rivers.”

IFI has a confidential hotline number to enable members of the general public to report incidents of water pollution, fish kills and illegal fishing or angling at 1890 34 74 24 or 1890 FISH 24.

#CleanCoasts - Almost 3,000 volunteers took to beaches around the country during Coca-Cola Clean Coasts Week 2015 to remove a staggering 10 tonnes of marine litter from the coastline.

With a target to remove a further 11 tonnes from beaches around the island of Ireland this year, Coca-Cola Clean Coast Week 2016 – which kicked off yesterday (Friday 6 May) and runs till next Sunday 15 May – is calling on volunteers across the island to once again get involved in the numerous coastal clean-ups and events taking place throughout the week.

Over 120 beach cleans are planned alongside more than 20 coastal celebration events across Ireland in celebration of the beautiful natural resource of the coastline and to raise awareness of the importance of keeping beaches clean from litter.

With the theme ‘Enjoy Your Beach, Enjoy Your Beach Clean’, the 2016 awareness week is run by the Environmental Education Unit of An Taisce in partnership with Coca-Cola and Keep Northern Ireland Beautiful.

The week sees range of fun and informative events with the aim of raising awareness of the importance of protecting our coastline. Coastal celebrations range from beach fitness activities that incorporate clean-ups, to a seal release in partnership with Seal Rescue Ireland at Curracloe Strand in Wexford, and talks on the role of marram grass planting in halting coastal erosion.

Other events include National #2MinuteBeachClean Day, the launch of Love Your Coast photography competition, and Beat the Microbead Day.

While all events throughout Coca-Cola Clean Coast Week 2016 are free, some are ticketed – visit www.cleancoasts.org for all the details.

At a sitting of Cavan District Court on 21st April 2016, Judge Denis McLaughlin convicted Irish Water in relation to a pollution incident arising from the wastewater treatment plant at Ballinagh, Co. Cavan.

Senior fisheries environmental officer Ailish Keane from Inland Fisheries Ireland (IFI) gave evidence that she had written to Irish Water on several occasions prior to the incident about failings at the treatment plant, but the company had not acted. On 20th June 2015, IFI staff noticed effluent entering the Ballinagh River and Ms Keane attended the scene and took samples. The samples showed very serious pollution of the river coming from the treatment plant, with levels of some pollutants almost 600 times higher than upstream.

In particular, the level of ammonia observed downstream was 17.9 milligrams per litre – 597 times the level of 0.03 milligrams per litre measured upstream, a level recognised as clean salmonid water. The level of suspended solids was 122 milligrams per litre, approximately 3.5 times higher than the plant’s allowed emission limit. The biological oxygen demand, a measure of bacterial growth in the water, was measured at 223.8 milligrams per litre downstream which is 45 times higher than what is expected in clean unpolluted water, and over 100 times higher than the level of two milligrams per litre observed upstream.

Judge Denis McLaughlin refused to consider a plea by defence counsel to consider a donation to charity, insisting that the delay in rectifying the issue by Irish Water, and the serious level of pollution, merited a conviction. He convicted and fined the company €2,500 in addition to costs amounting to €3,917.43.

Commenting on the case, Dr Ciaran Byrne, CEO of Inland Fisheries Ireland, said: “Protection of fish stocks and water quality is vital to maintaining an extremely valuable natural resource for the benefit of local and tourist anglers alike. Inland Fisheries Ireland is committed to protecting the most vital component of good habitat to fish – high water quality. Our staff will continue to monitor and enforce water quality legislation in order to maintain healthy fish stocks.”

Inland Fisheries Ireland (IFI) has a confidential hotline number to enable members of the general public to report incidents - 1890 34 74 24 or 1890 FISH 24. This phone line is designed to encourage the reporting of incidents of illegal fishing, water pollution and invasive species.

#Rio2016 - Rio's water 'will be ready' for sailors when the Olympic Games begin in August, according to China's Xinhua News Agency.

Speaking at an event to mark the lighting of the Olympic torch in Athens on Thursday (21 April), International Olympic Committee president (IOC) Thomas Bach told the media: "We are very confident that the competition area for the athletes will offer safe and fair conditions.

"The city, the state and the organising committee are undertaking many efforts and what we see now is that 60% of the surface is clean," he added. "Without the Games it would be zero."

However, Bach made no reference to concerns over viral contamination of the notoriously polluted Guanabara Bay, nor the risk posed to female sailors by the spread of the Zika virus.

#MarineWildlife - There's some good news for marine wildlife in Clare and around the Irish coast as a recent study on the health of whales and dolphins in Europe's oceans identified Ireland's population as among the world's healthiest.

As previously reported on Afloat.ie, the paper in journal Scientific Reports identified lingering traces of now banned chemicals called PCBs that are still affecting the reproductive rates of cetaceans in European waters, particularly killer whales.

Biopsy samples of dolphins from the Shannon Estuary were included in the global study – but all indications are that the whales and dolphins that populate the sanctuary of Irish waters are among the healthiest in the region, though they still face the threat of pollutants in the Shannon Estuary, as the Clare Champion reports.

#MarineWildlife - Toxic chemicals banned in Europe nearly 30 years ago are still polluting the seas off the continent.

And marine scientists fear their continued presence could spell the end for the killer whale and other species in European waters, as the Irish Examiner reports.

The warning comes from newly published research on concentrations of polychlorinated biphenyls, or PCBs, in marine wildlife – specifically orcas and other dolphins – in Irish, British and Mediterranean waters.

Co-authored by Dr Simon Berrow of GMIT and the Irish Whale and Dolphin Group, the paper in the latest issue of journal Scientific Reports claims that despite the outright ban on the use of PCBs since 1987, they persist in "dangerously high levels in European cetaceans".

High exposure to PCBs, once used in the manufacture of paints and electrical equipment, weakens the immune systems of cetaceans and has a severe effect on their breeding rates.

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.
