#InlandWaters - The Heritage Bill 2016, including a raft of changes to the Canals Act, was presented to the Oireachtas on 4 January last.

Pages 5 to 13 and 22 of the Heritage Bill will be of particular interest to canal users as they detail the proposed amendments to bye-laws from the 1986 Act, many of which have come under scrutiny from inland boaters since they were first suggested in the summer of 2014.

The bye-law amendments include provisions for the "charging and fixing of fees, tolls and charges in respect of the use by boats of the canals (including the use of locks on the canals and mooring on the canals) and the taking of water from the canals".

Details of any such new bye-laws will be published on the Waterways Ireland website and in local newspapers, and users may submit objections during the 21 days from the first publication of notice.

The Heritage Bill is available as a PDF to read or download HERE.

#Flooding - Water levels on Lough Neagh are at a 30-year high, and business owners in the region are counting the cost of flooding on their livelihoods, as Belfast Live reports.

A number of traders are battling to stay open despite the deluge, which came after the wettest December on record.

And the rainy trend shows no sign of letting up, with showers forecast every day till early next week.

"We're still open but nobody can get in to us," said David Cochrane of Custom Covers NI, who is keeping his new Kinnego Marina unit open despite five inches of flood waters.

"It's a bit of a mess to say the least. The financial side of it has cost me a lot."

Yesterday BBC NI weatherman Barra Best posted video of the damaging flooding at the marina on the southern end of Ireland's largest lake.

#Pollution - The effects of diesel laundering over decades in South Armagh are being felt even greater today, say Dundalk anglers, as the New Year starts with the River Fane closed to all but catch-and-release fishing.

As Independent.ie reports, a 10-fold decrease in stocks of salmon as well as brown trout and sea trout in the river, which flows into Dundalk Bay from the Monaghan-Armagh border, is the direct result of diesel laundering operations by the IRA since at least the 1980s.

Waste from the process of converting subsidised agricultural 'green' diesel to 'white' diesel for general road use has reportedly been dumped openly into a tributary of Lough Ross, which feeds into the Fane – a river that supplies drinking water to Dundalk and much of North Louth.

A recent study found that these pollutants include polycyclic aromatic hydrocarbons or PAHs, the same chemicals that continue to affect spawning grounds in areas impacted by the Exxon Valdez oil spill in Alaska 26 years ago.

#Flooding - Moves to prevent flooding in the Shannon catchment may be in breach of EU habitats directives, as The Irish Times reports.

Next Tuesday (5 January) the Taoiseach is expected convene a meeting of all relevant State agencies to discuss flood measures along the River Shannon.

And according to Simon Harris, Minister of State for the OPW, some suggestions – such as dredging and flood barriers – "will breach the EU directives" as they pose a threat to fish and birdlife.

The Shannon and its catchment are home to a number of protected species from salmon to kingfishers.

But Minister Harris said flood prevention measures were a necessity when the river catchment faces "a humanitarian crisis in some areas" due to flooding that began with Storm Desmond nearly a month ago.

It's a situation that will only deteriorate over time, with Met Éireann indicating that climate models predict worsening winter floods further into this century.

#MarineScience - Climate change is rapidly warming lakes around the world, threatening freshwater supplies and ecosystems, according to a new study spanning six continents.

More than 60 scientists took part in the research, published in the journal Geophysical Research Letters and announced at the fall meeting of the American Geophysical Union on Wednesday 16 December.

The study – based on global analyses including unique long-term data from the Marine Institute's catchment research facility at Newport, Co Mayo – found that lakes are warming an average of 0.34C, or 0.61F, each decade.

That's greater than the warming rate of either the oceans or the atmosphere, and it can have profound effects, the scientists say.

At the current rate, algal blooms – which can ultimately rob water of oxygen – are projected to increase 20 percent in lakes over the next century. Algal blooms that are toxic to fish and animals would increase by five percent.

These rates imply that emissions of methane, a greenhouse gas 25 times more powerful than carbon dioxide, will increase four percent over the next decade.

"Lakes are important because society depends on surface water for the vast majority of human uses," said co-author Stephanie Hampton, director of Washington State University's Center for Environmental Research, Education and Outreach.

"Not just for drinking water, but manufacturing, for energy production, and for irrigation of our crops. Protein from freshwater fish is especially important in the developing world."

Temperature is one of the most fundamental and critical physical properties of water. It controls a host of other properties that include intricate living processes that have evolved within strict boundaries.

When the temperature swings quickly and widely from the norm, life forms in a lake can change dramatically and even disappear.

"These results suggest that large changes in our lakes are not only unavoidable, but are probably already happening," said lead author Catherine O'Reilly, associate professor of geology at Illinois State University.

Earlier research by O'Reilly has seen declining productivity in lakes with rising temperatures.

Funded in part by NASA and the National Science Foundation, the study is the largest of its kind and the first to use a combination of long-term hand measurements and temperature measurements made from satellites, offsetting the shortcomings of each method.

Study co-author Simon Hook, science division manager at the NASA Jet Propulsion Laboratory, said satellite measurements provide a broad view of lake temperatures over the entire globe. But they only measure surface temperature, while hand measurements can detect changes in temperature throughout a lake. Also, satellite measurements go back only 30 years while some lake measurements can go back more than a century.

Lough Feeagh in Co Mayo was one of 235 lakes in the study that have been monitored for at least 25 years. While that's a fraction of the world's lakes, they contain more than half the world's freshwater supply.

The Marine Institute measures the surface water temperature of Lough Feeagh as part of the long term ecological monitoring of the Burrishoole catchment. The Burrishoole research station is an internationally important index site for diadromous fish monitoring, and water temperature is a crucial variable controlling growth, migration and survival of salmon, trout and eel in the catchment.

"The inclusion of data from Lough Feeagh in this study highlights the value of collecting local environmental long term data to inform global analyses," said Dr Elvira de Eyto, a biologist at the Marine Institute facility in Burrishoole and one of the studies co-authors.

Marine Institute chief executive Dr Peter Heffernan added: "The sharing of such data with global scientific networks makes an important contribution to worldwide climate change analyses, and our understanding of how the warming climate will affect our valuable aquatic resources."

The surface water of Lough Feeagh has warmed at a rate of 0.35C per decade between 1985-2009, although the rate of warming was lower than some other northern hemisphere lakes.

"We want to be careful that we don't dismiss some of these lower rates of change," said Hampton. "In warmer lakes, those temperature changes can be really important. They can be just as important as a higher rate of change in a cooler lake."

The researchers said various climate factors are associated with the warming trend. In northern climates lakes are losing their ice cover earlier, and many areas of the world have less cloud cover, exposing their waters more to the sun's warming rays.

Many lake temperatures are rising faster than the average air temperatures. Some of the greatest warming is seen at northern latitudes, where rates can average 0.72C, or 1.3F, per decade.

Warm-water, tropical lakes may be seeing less dramatic temperature increases, but increased warming of these lakes can still have large negative impacts on fish. That can be particularly important in the African Great Lakes, home to one-fourth of the planet's freshwater supply and an important source of fish for food.

In general, the researchers write: "The pervasive and rapid warming observed here signals the urgent need to incorporate climate impacts into vulnerability assessments and adaptation efforts for lakes."

#Drones - Filmmakers have been using consumer-grade drones to capture some stunning footage in recent times, and this incredible video of Lough Eske is no exception.

Spanish video company eldrone.es launched from the grounds of Solis Lough Eske Hotel in Donegal to capture the breathtaking beauty of the lake in glorious 4K quality.

Meanwhile, Irish Rail released a similarly sweeping aerial view of the recently refurbished Drogheda Viaduct, after €6.1 million of EU-funded works that saw the installation of a new drainage system, waterproofing and state-of-the-art lighting.

It's a fitting facelift for Sir John MacNeill's engineering marvel that has spanned the River Boyne for 160 years.



Aerial photographer Dennis Horgan may not use a drone for his vistas, opting for helicopters and fixed-wing aircraft to get in position for the right shot, but his latest images captured over Dublin Bay are all the more impressive for it.

Indeed, a number of Dublin's waterfront landmarks appear in TheJournal.ie's gallery of his bird's eye view of the capital, many seen from unusual angles.

#Flooding - Flooding in the Shannon catchment is still "severe" according to the National Emergency Coordination Group,

As RTÉ News reports, waters have risen by 2.5cm in the Athlone area, where the Shannon breached its banks before the weekend.

And levels expected to peak on the Lower Shannon later today (Monday 14 December) between Lough Derg and Limerick, which experienced serious flooding in parts of the city not normally affected.

However, as rain persists over coming days, counties in the South and South West remain at risk, as heavy rainfalls "could cause flooding in areas have had no flooding so far".

Meanwhile, at the other end of the waterway, Lough Erne burst its banks in the Enniskillen area at the weekend – rendering a number of roads impassable, as the News Letter reports.

#Flooding - The Defence Forces have joined in flood relief efforts in Clare, Limerick and Westmeath as weekend rains risk significant flooding in the region.

As reported yesterday on Afloat.ie, the Shannon Catchment could see its worst flooding in two decades as spring tides exacerbate the effects of last weekend's Storm Desmond, which prompted a rare 'Status Red' warning for rainfall.

RTÉ News reports that the Shannon is already at dangerous levels, with a flood emergency response launched in Athlone after the waterway breached its banks in the Midlands town, threatening 100 homes.

Homes were also evacuated in Clonlara, Co Clare – between the Shannon and the Headache Canal – while the ESB was releasing water at its Inniscarra Dam facility in Cork to manage reservoir levels, warning of a subsequent risk downstream on the River Lee.

Meanwhile, Waterways Ireland has advised boaters to keep their vessels moored during this and other periods of stormy weather "and especially when national weather alerts are in place".

Even when the storms have passed, "users should be aware that the navigations will have changed significantly in nature and character" with the risk of strong currents, rising waters from flash flooding obscuring navigation markers, and falling trees weakened by storm-force winds.

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.
