#Rio2016 - Brazil has hurried to squash growing fears over the safety of sailing waters for next summer's Rio Olympics – but one state official's dip in Guanabara Bay hasn't stemmed the backlash.

The Associated Press reports on the "televised stunt" last week that saw environmental secretary Andrea Correa dive into the waters where sailors are expected to race just over a year from now.

In the footage recorded for the news magazine show Fantastico – which previously aired a report highly critical of Rio's failure to fulfil its promises to clean up the notoriously polluted Guanabara Bay – Correa compared its waters to the popular beaches of "Ipanema or Barra".

But the PR exercise did not impress the Fantastico team, who stressed in their programme that the official selected the time and place for his dip, at high tide near the mouth of the bay in cleaner ocean water.

Commenting on the story at the Royal Cork YC website, Peter Webster – a chemist with the Environmental Protection Agency (EPA) – repeated concerns that Rio's sailing waters fall far short of European bathing water quality standards.

"For our Olympic competitors... these standards should be being demanded by the ISA or the relevant swimming national bodies," he says. "From the evidence I’ve seen of pollution in Guanabara Bay there is no way that water-sports of any kind should be being held there."

The ISAF has already suggested it could make a formal call to move Olympic sailing out of the city for the safety of athletes.

#Rio2016 - Annalise Murphy, James Espey, Ryan Seaton and Matt McGovern are already Rio-bound - but could their sailing venue at the 2016 Olympics be moved out of Guanabara Bay?

That's what the sport's world governing body has threatened to do if city authorities don't clean up their act, according to the Associated Press.

As previously reported on Afloat.ie, local Olympic officials have confirmed that the notoriously polluted waters of Brazil's largest city will not be fully cleaned as promised in time for next summer's Olympiad.

The sailing venue was slammed as "absolutely disgusting" by Irish Olympic sailing coach Ian Barker on a visit to Rio at the end of 2013.

Yet while hopes remained in the interim that city officials would make good on their assurances of safe and clean waters for sailors, those have been dashed in recent weeks – with safety concerns over floating rubbish and the discovery of a new 'super-bacteria' in one of the many sewage-filled rivers that flow into the bay.

That's not to mention similar worries over the venue for rowing and canoeing at the Rodrigo de Freitas Lagoon – recently the site of an extensive fish kill.

The situation has now prompted the ISAF to call on the International Olympic Committee (IOC) to step up the pressure on Brazil's politicians, with the sailing body's Alastair Fox claiming he and fellow officials were "frustrated with it all".

In a phone interview with the AP's Stephen Wade, Fox said: "We are going to review the situation and make some more recommendations – demands is probably the right word – to make sure things are done."

The ISAF's head of competitions also suggested that "if we have to race all the races outside the bay, if that's what it comes to, to ensure a fair regatta, then that's something we're going to explore and could do."

#CoastalNotes - Ireland gets an 'A' for seaside bathing, as 94% of beaches have met the EU's new stricter water quality standards.

And as RTÉ News reports, three out of every four Irish beaches have been rated as 'excellent' on the new scale for levels of microbiological contaminants, which is "twice as strict" as in previous years.

But seven out of 136 bathing places monitored by the Environmental Protection Agency (EPA) in 2014 still failed the test.

Youghal in Cork, Clifden and Ballyloughane in Galway, Rush's south beach in North Co Dublin, Duncannon in Wexford, Ardmore in Waterford and Liliput on Lough Ennell in the Midlands were all rated 'poor', for the most part due to wastewater discharges.

Ten other popular seaside spots – including Trá na mBan in Spiddal and the beaches at Merrion Strand, Loughshinny and Balbriggan's front strand in Co Dublin - were rated as 'sufficient' as they are still prone to periodic pollution episodes, according to The Irish Times.

But there was good news for the denizens of Trá Inis Oirr in Galway Bay, which scored an 'excellent' rating in its first year on the EPA's list.

The Aran Islands beach was added in the same year that nearby Trá gCaorach became a first-time winner in the National Green Coast Awards.

The EPA's Splash website maps out the latest bathing quality ratings for beaches around and throughout Ireland. The agency's report on bathing quality in 2014 can be found HERE.

#CoastalNotes - Is Connemara at risk of disappearing into the sea? According to one geologist, that's a distinct possibility.

As the Irish Mirror reports, Jonathon Wilkins noticed that the tide was flooding channels in a peat bog near NUI Galway – a tell-tale sign of 'post-glacial rebound'.

That's the process of the land recovering from the weight of glaciers during the Ice Age, and in most cases it means the level of the earth is rising, such as northern parts of the island of Ireland.

But Connemara is one of those that's dropping, and slowing slipping below sea level as the seawater effectively dissolves the bogs and granite bedrock.

Wales-based geological expert Wilkins described what he saw as "very powerful evidence that sea level, to my surprise, is rising in this area, and demonstrably over quite a short time scale."

Disappearing even faster into the sea is an old landfill site in Bray – and it's raised the ire of environmentalists.

According to the Belfast Telegraph, the disused rubbish tip north of the Co Wicklow seaside town continues to lose some of its 200,000 tonnes of refuse into the Irish Sea due to coastal erosion.

And that's despite the problem being identified more than 20 years ago, according to Coastwatch – which says some 200 metres of the face of the landfill site has been exposed by weathering, littering the cliffs below.

The pollution only adds to the 8.8 millions tonnes of plastic that's dumped into the world's oceans every year, according to the journal Science.

The Irish Times reports on these latest findings, which show that one third of this plastic waste is produced by China alone.

#Rio2016 - Rio is turning to Dutch researchers for help in combating its water pollution problems that continue to cause concern for the Olympic sailing fleet.

As the Associated Press reports, water research foundation Deltares has developed technology using data collected from both weather and water conditions to predict areas where litter accumulates, allowing Rio authorities to focus their clean-up efforts more efficiently.

It comes some days after a programme to retrieve floating rubbish from the sailing venue in Guanabara Bay was halted by city officials, reviving fears that Rio's 'dirty water problem' will not be solved in time for the 2016 Games.

Objects floating in the water have been cited as a major cause of concern by both Olympic and world sailing organisers, but water-borne contaminants have also been highlighted.

Last December news emerged of a newly discovered 'super-bacteria' that could pose a significant threat to health at next year's Summer Olympics for competitors like Annalise Murphy, James Espey, Ryan Seaton and Matt McGovern who have already nabbed their spots and will be training in Rio's "absolutely disgusting" waters ahead of the Olympics.

#InlandWaters - "An absolute disgrace" is how a judge branded a Longford farmer convicted of polluting a local lake near Lough Ree with slurry from his pig farm.

According to The Irish Times, Donal Connaughton of Newtowncashel was found to have caused or permitted effluent to fall from up to 25 slurry tanks containing a total of four million gallons from his property in March last year.

Longford District Court heard that many of the tanks were unauthorised structures and that Connaughton had removed their roofs to comply with a previous demolition order, only making the pollution problem worse by allowing overflow to enter local water courses.

Judge Séamus Hughes jailed Connaughton for 10 weeks and fined him €3,000 with €5,400 costs. The Irish Times has more on the story HERE.

#Rio2016 - A newly discovered 'super-bacteria' could pose a serious threat to the health of sailors competing at the next Summer Olympics in Rio.

According to Reuters, scientists in the Brazilian city have found a strain of bacteria that can cause any number of internal infections – but is resistant to antibiotics.

The bacteria was discovered in samples taken from a river that feeds into the main sailing grounds for Rio 2016 at Guanabara Bay.

The latest news will be of grave concern to sailors like Annalise Murphy, James Espey, Ryan Seaton and Matt McGovern who are already headed to Rio and will frequent the city for competitions and training camps over the next 18 months leading up to the games.

It also comes after the disappointing news earlier this year that pollution issues in Rio's waters will not be solved in time for the Olympiad - a year after Irish Olympic coach Ian Barker described the city's waters as "absolutely disgusting".

#MarineScience - The final report for Biological Effects and Chemical Measurements in Irish Marine Waters has just been published after four years of collaborative research led by Trinity College Dublin in partnership with the Marine Institute, Shannon Aquatic Toxicity Laboratory (Enterprise Ireland) and Dublin Institute of Technology.

The marine environment is affected by a complex mixture of man-made and naturally-occurring substances derived from a variety of sources such as shipping, sewage or industrial discharges or through accidental or historic spills of hazardous substances.

“Current monitoring and assessment of the pollution status of the marine environment in Ireland is mainly reliant on chemical measurements of contaminants in sediments, water and in 'bio-indicator' species," said Prof Jim Wilson of TCD. 

"The success of this pilot project is that it reports the first major Irish study that examined both pollutant levels in the coastal environment while concurrently assessing the potential for biological-based effects on organisms exposed to these often hazardous substances."

Drawing on diverse expertise provided by a number of Government and academic research institutions, the study completed testing of a variety of chemical and biological-based monitoring tools in diverse coastal locations in Dublin, Wexford, Cork, Kerry, Clare and Galway.

The project confirmed that Irish coastal water quality is generally good, with the most elevated pollutant levels detected typically at more populated locations subject to greater impacts and pressures.

Lower pollutant levels were generally evident in less populated areas where diffuse pollution rather than local sources are of greater relevance.

In isolation, chemical measurement studies do not always explain the potential of the pressures that affect the ecosystem as a whole. The findings of this report note that using a suite of biological effects as part of an integrated approach to support chemical measurements gives a better overview of the health of our marine ecosystem.

For example, chemical compounds and mixtures present in the environment in combination with natural changes in the ocean, such as salinity or temperature, can all work in synergy or against each other to elicit diverse effects on the marine environment and on resident marine species.

“Individual pollutants or a mix of chemicals can cause metabolic disorders, increases in diseases becoming more common, as well as having an adverse effect on population growth and on species reproduction potential," said Dr Michelle Giltrap of TCD. 

"An example of this is the reproductive effects on dog whelks, which were affected by the legacy of exposure to the biocide Tributyltin (TBT). TBT was widely used as an effective antifoulant on the hulls of ships and boats to prevent growth of aquatic organisms. Although use of TBT has been phased out internationally, the effects are still evident, but have been diminishing over time."

Dr Brian Donlon, who manages the Environmental Protection Agency's Research Programme, said “ongoing international commitments under the Marine Strategy Framework Directive require that member states monitor pollution in their marine waters by assessing both the level of chemical contamination and the effects of this contamination on organisms.

"Continued research and monitoring is required in order to further develop the dedicated chemical measurement and ecotoxicological response datasets.”

Dr Brendan McHugh of the Marine Institute added: “Integrated biological effects and chemical monitoring, including use of the novel tools, offer the potential for a more ecologically oriented approach to pollution monitoring and for further enhancing and supporting management actions in maintaining a sustainable marine environment."

The full report is available HERE on the Marine Institute’s Open Access Repository. The research project and was carried out under the Sea Change Strategy and the Marine Sub-Programme of the National Development Plan 2007-2013, and was jointly funded by the EPA and the Marine Institute.

#Rio - Rio de Janeiro's dirty water problem will not be solved by the time the Brazilian city hosts the next summer Olympic Games in 2016, as The New York Times reports.

Despite promises by city officials as far back as 2009 that Guanabara Bay and Rio's waterways would be cleaned of sewage and refuse by at least 80%, a recent letter obtained by the Associated Press news agency claims that at the current funding rate it would take a decade to reduce pollution to acceptable levels.

The letter from the office of Rio's state environment secretary to Sports Minister Aldo Rebelo is backed up by an AP analysis of national statistics which shows pollution in the city's waters is far above Brazil's national limits, which are themselves regarded as less stringent when compared to European standards.

As reported last December on Afloat.ie, Irish Olympic sailing coach branded the future Olympic waters of Rio as "absolutely disgusting", comparing Guanabara Bay to a "sewer" where training sailors had to repeatedly stop to disentangle refuse from their rudders.

State authorities are now asking for $70 million to build new river water treatment units to filter out waste before it reaches the bay, though it's expected to reduce current pollution levels by just 50% in time for the first sailing events.

#CoastalNotes - The vast majority of Irish beaches are fit for bathing, according to the latest figures from the Environmental Protection Agency (EPA).

But as The Irish Times reports, any bathing spots that fail to meet the EU's minimum requirements in future will be closed for an entire season.

Of the 135 bathing places assessed by the EPA over the past 12 months, just four were rated as 'poor' quality.

Two of these were in Co Galway - Ballyloughane in Galway city, which experienced two pollution incidents; and Clifden, which "continues to be subject to episodic pollution" after it was identified among 40 towns nationwide still discharging raw sewage, though work is ongoing to upgrade the local treatment plant.

Some 114 bathing spots were rated 'good', and would have been rated higher if not for low but persistent bacterial levels in some East Coast waters.

Nationwide, the EPA's verdict is that better wastewater management practices have resulted in improving standards, maintaining Ireland's position as "one of the best countries in northern Europe" for water quality.

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.
