As Cop26 continues to debate methane – with the US And EU having pledged to reduce agricultural methane outputs from ruminant livestock by upwards of 30% by 2030 – scientists at the Institute for Global Food Security (IGFS) at Queen’s University Belfast are to feed seaweed to farm animals in a bid to slash methane by at least 30%.

Seaweed has long been hailed a ‘superfood’ for humans but adding it to animal feed to reduce methane gas released into the atmosphere by ruminants' burping and flatulence is a relatively new idea. Early laboratory research at IGFS has shown promising results using native Irish and UK seaweeds.

Previous research in Australia and the USA generated headline results – up to 80% reductions in methane emissions from cattle given supplements from a red seaweed variety. These red seaweeds grow abundantly in warmer climates; however, they also contain high levels of bromoform – known to be damaging to the ozone layer. Seaweed indigenous to the UK and Ireland tends to be brown or green and does not contain bromoform.

UK and Irish seaweeds are also rich in active compounds called phlorotannins, found in red wine and berries, which are anti-bacterial and improve immunity so could have additional health benefits for animals.

Now the IGFS science is moving into the field, with trials on UK farms about to begin, using seaweed sourced from the Irish and North Seas as a feed supplement for cattle.

One 3-year project is in partnership with the UK supermarket Morrisons and its network of British beef farmers who will facilitate farm trials. The project also includes the Agrifood and Biosciences Institute (AFBI), in Northern Ireland, as a partner.

A second project sees IGFS and AFBI join a €2million, international project - led by Irish agency An Teagasc - to monitor the effects of seaweed in the diet of pasture-based livestock. Seaweed will be added to grass-based silage on farm trials involving dairy cows in NI from early 2022.

As well as assessing methane emissions of the beef and dairy cattle, these projects will assess the nutritional value of a variety of homegrown seaweeds, their effects on animal productivity and meat quality.

IGFS lead Sharon Huws, Professor of Animal Science and Microbiology within the School of Biological Sciences, said she expected the combined research to evidence a reduction in GHG emissions of at least 30%.

She said: “The science is there. It’s simply a matter of providing the necessary data and then implementing it. Using seaweed is a natural, sustainable way of reducing emissions and has great potential to be scaled up. There is no reason why we can’t be farming seaweed – this would also protect the biodiversity of our shorelines.

“If UK farmers are to meet a zero-carbon model, we really need to start putting this kind of research into practice. I hope IGFS and AFBI research can soon provide the necessary data and reassurance for governments to take forward.”

Agriculture accounts for around 10% of all UK GHG emissions. Within this, beef farming is the most carbon-intensive, with methane, which cows produce as they digest, a major component. At a NI level, methane accounts for almost a quarter of GHG emissions, with 80% of that from agriculture.

The above projects form part of the Queen's-AFBI Alliance – a strategic partnership between Queen’s University and AFBI to maximise science and innovation capacity in NI to meet global challenges, such as carbon-neutral farming.

Morrisons supermarket plans to be completely supplied by net-zero-carbon British farms by 2030. Sophie Throup, Head of Agriculture at Morrisons said: “As British farming's biggest customer, we’re very mindful of our role in supporting and inspiring the farmers we work with to help them achieve goals in sustainable farming.

“By supporting this research at Queen’s and AFBI, we are trialling this natural approach to reducing environmental emissions and improving the quality of beef products.”

New research at Queen’s University highlights the impact that microplastics are having on hermit crabs, which play an important role in balancing the marine ecosystem.

The research found that microplastics are affecting the behaviour of hermit crabs, namely their ability during shell fight contests, which are vital to their survival.

There is a strong association between hermit crabs and their shelters or shells, which are taken from marine snails to protect their soft abdomens. As the hermit crab grows over the years, it will need to find a succession of larger and larger shells to replace the ones that have become too small. They can achieve this through a contest, termed a shell fight, involving the ‘attacker’ rapping their shell against the ‘defender’ in an attempt to evict the opponent from its shell. In these contests, the hermit crabs will fight a competitor to secure the shell that they favour. These shells are vital in protecting and enabling hermit crabs to grow, reproduce and survive.

The new study builds on previous research by Queen’s University that showed hermit crabs were less likely to touch or enter high-quality shells when exposed to microplastics.

The new study, published in Royal Society Open Science, provides a more in-depth insight into how the hermit crabs behaviour is affected when exposed to microplastics. The microplastics impair both the attacking and defending behaviour of hermit crabs during contests, impeding their ability to secure the larger shell that is required for both their growth and survival.

The research involved keeping hermit crabs in two tanks: one which contained polyethylene spheres (a common microplastic pollutant) and one without plastic (control) for five days. The team simulated the environment to encourage a hermit crab contest through placing pairs of hermit crabs in an arena, giving the larger crab a shell that was too small and the smaller crab a shell that was too big. Plastic-exposed hermit crabs displayed weaker attacking behaviour (known as rapping) during fights than crabs that were not exposed to plastic. Microplastics also reduced the ability of defending crabs to properly assess their attackers during contests and impaired their decision to give up their shell earlier.

Hermit crabs are known as scavengers as they recycle energy back into the ecosystem through eating up decomposed sea-life and bacteria. As such they play a vital role in rebalancing the ecosystem and are an important part of marine life.

Manus Cunningham from Queen’s University and one of the lead researchers on the paper, said: “These findings are hugely significant as they illustrate how both the information-gathering and shell evaluations were impaired when exposed to microplastics.

“Although 10% of global plastic production ends up in the ocean, there is very limited research on how this can disrupt animal behaviour and cognition. This study shows how the microplastic pollution crisis is threatening biodiversity more than is currently recognised.”

Dr Gareth Arnott, the principal investigator of the project said: “This study provides an insight into the potential for microplastics to alter important aspects of animal behaviour that are critical for survival and reproduction. We need to further investigate how microplastics affect their behaviour and the consequences, armed with this knowledge to advocate for change to protect our ecosystem.”

The 1.5 metre unmanned mini sailboat called 'Seoltóir Na Gaillimhe – the Galway Sailor', that was deployed in June, was recently found stranded on the Bunes Beach above the Arctic Circle in the Lofoten Islands, in Norway.

After travelling over 3,000km from Irish waters in the Atlantic to Norway, the 'Seoltóir Na Gaillimhe – the Galway Sailor' was found by the Bjørnsen family and friends while on holidays on the Lofoten Island over the summer, the Marine Institute’s Explorers Education Programme has reported.

Mr Lars Bjørnsen said his daughters were thrilled to discover the mini boat washed up on the remote Bunes Beach, “our neighbour had found the boat and my three girls were so excited to join him to open the hatch of the boat to see the Irish messages and ‘treasures’ inside. We were able to read most of the letters that had been written by the students at Kilglass National School in Galway, although some were a little wet. The girls were also delighted with the Irish candy and crisps – which survived the voyage.”

“Bunes Beach is quite isolated on the western side of Reinefjorden on the Moskenesøya island, Norway. You can only get there by ferry and then have to walk 3km to the beach. It is a beautiful beach in a bay surrounded by mountains and steep ridges. However, not many people get to go there on a regular basis. Therefore, the fact that we found the Galway Sailor mini boat, that had made its way into the bay and then washed up on the shore with little structural damage is amazing for such a small boat,” Mr Bjørnsen further explained.

The 'Seoltóir Na Gaillimhe – the Galway Sailor' is a 1.5 metre unmanned mini sailboat that was provided to Kilglass National School in County Galway, as part of a collaborative school project, coordinated by the Marine Institute’s Explorers Education Programme and supported by the international Educational Passages programme in the USA. The project was also funded by EU Interreg iFADO (Innovation in the Framework of the Atlantic Deep Ocean) project, in which the Marine Institute are partners.

Welcoming the news of the boat being found, Mick Gillooly, Interim CEO said, "The Explorers mini-boat project is a great example of marine science literacy and engaging with the community at a local school level in Ireland as well as across the ocean in other countries. For school children, this project provides an exciting way of seeing real life examples of how the ocean has an influence on all our lives, how it connects us, as well as learning how the ocean influences our weather and climate, and the types of technology used at sea. The Marine Institute are delighted to have been involved with this project and look forward to supporting this collaboration involving the Explorers Education Programme team, Kilglass National school, the Research Infrastructures team at the Marine Institute, as well as Educational Passages in the USA with the ongoing mini boat adventures'.

The mini boat was equipped with a sail and a satellite tracker, which allowed the students at Kilglass NS to track it as it sailed across the ocean, using the international Educational Passages tracking system. Mr Peter Kane, who was the school teacher leading the project at Kilglass National School in Ahascragh, Co Galway was thrilled with the news from Norway and thanked the Bjørnsen family for their lovely message sent to the school children in Galway. “It is truly a mini-summer miracle! Everyone at Kilglass National School are so delighted with the news that our mini-boat 'Seoltóir na Gaillimhe' has been found in Norway. When the mini boats are found after their travels, this highlights how the ocean connects us all”.

The Explorers Education Programme’s marine project involved over 100 children taking part in science, geography and art activities learning about the ocean; as well as preparing the mini boat for its journey. The students painted and decorated the boat, created artwork and good luck messages, and named the boat 'Seoltóir Na Gaillimhe – the Galway Sailor', which recognises the tradition of fishing in Galway. The mini boat was launched by the Marine Institute’s RV Celtic Explorer near the M6 Data Buoy, in the Atlantic Ocean during a scientific survey in June.

Peter Kane also commented on the collaboration with the Marine Institute’s Explorers Education Programme, highlighting the importance of marine themes used on the curriculum in Ireland. “The Educational Passages mini boat programme brings children, schools and countries together in so many different ways, from building the boats, tracking them at sea, to finding them in new countries when they reach land.”

“When the 'Seoltóir Na Gaillimhe – the Galway Sailor' last reported its GPS location near the Faroe Islands in June, we didn’t know whether the boat had been damaged or was still drifting with the currents and winds. We were therefore thrilled to get a call from Cassie at Educational Passages to let us know that 'Seoltóir Na Gaillimhe – the Galway Sailor' made it back to land in Norway,” Mr Kane said

The Marine Institute’s ocean modellers have since provided a map showing the likely journey of the 'Seoltóir Na Gaillimhe – the Galway Sailor' after it lost its GPS tracking signal. Knowing the last coordinates, as well as where the boat was found, the team were able to produce a map showing the boats likely movement based on the currents and wind direction at the time. It was estimated that the boat travelled over 3000km from when it was deployed in the Atlantic.

Mr Kane further said, “we were also excited to find out that our boat had also set a new record for the most northern journey ever made by one of the unmanned mini-boats with Educational Passages. We now look forward to the next stage of working with the Explorers Education Programme and linking our students with the local Norwegian Primary School, who have taken over the boat’s next new adventure.”

Sea and sky, as in the marine and astronomy, were twin themes of this year’s “Young Hearts”, a field programme involving transition year students working with senior citizens in Galway.

Tutors Dr Noirin Burke of Galway Atlantaquaria, artist Vicky Smith and astronomy experts Prof Andy Shearer and Adriana Cardinot of NUI Galway drew up a curriculum involving marine biology, astronomy and art.

Prof Shearer explained that the “Sky and Earth” module was supported by a Royal Astronomical Society award, marking its bicentenary.

The overall aim of the intergenerational programme is to build relationships and solidarity, according to co-ordinator Loretta Needham of Croí na Gaillimhe.

In spite of Covid 19, “Young Hearts” continued on Zoom over the past year, with pupils from Our Lady’s College, Galway and older members of the community.

Needham explained that isolation has been an issue for senior citizens long before Covid-19, and the programme aims to “create a foundation for lifelong social responsibility and understanding among young people”.

Marine survival of salmon in the eastern North Atlantic has substantially declined in recent decades, yet little was known about the migratory behaviour and distribution of populations. A new genetic tagging study, just published in the international journal Fish & Fisheries, shows where young salmon gather and begin to migrate during their first summer at sea; migrating along the the continental shelves off Ireland, Scotland and Norway and subsequently aggregating to feed in the Norwegian Sea west of the Vøring Plateau in international waters (those waters outside national jurisdiction). Here they are exposed to potential mortality from major commercial fisheries for other pelagic species. 

The genetic analysis of fish caught at sea demonstrates that the salmon stocks that make up this feeding aggregation are unexpectedly not from neighbouring Norwegian rivers, but are predominantly from southern rivers such as those in Britain, Ireland, France and Spain.

This points to fundamental differences in migration behaviours (routes) and likely explains variation in how stocks from Northern and Southern European rivers have been responding to environmental change and critically to recent climate change, and may account for the differences that have been observed among stock groups in marine survival.

Joint senior author of the paper, Prof. Philip McGinnity of UCC and the Marine Institute said, “This report is the culmination of a major logistical and technical effort to synthesise the data from 385 marine cruises, 10,202 individual trawls, 9,269 captured post smolts, spanning three decades and approximately 4.75 million Km2 of ocean and 3,423 individuals assigned to their region of origin.” 

Further adding, “A post smolt salmon at 25cm is a very small and rare fish in a very large ocean and so to firstly catch and then assign a couple of thousand fish back to their region and even, potentially, their river of origin is a considerable feat.”

The sampling was largely carried out by research vessels, such as the Marine Institute’s RV Celtic Explorer (pictured), from several European countries and the laboratory analysis by many European labs.

In addition to the large team of international researchers from the UK, Norway, Faroes, Denmark, Russia, France, Spain, Finland, Irish scientists from University College Cork, the Marine Institute, Queen’s University Belfast, the Atlantic Salmon Trust, the Loughs Agency and the Agri-Food and the Biosciences Institute for Northern Ireland were centrally involved.

Professor Tom Quinn of the University of Washington’s School of Aquatic and Fishery Sciences, a leading world authority on salmon has welcomed the study, saying “This paper is the result of sampling efforts that were vast in space and time, and equally impressive collaboration including research agencies and universities from many nations. The scope of this study alone is most impressive, and the results are of great importance. These scientists have revealed rich variation in the early marine migrations of Atlantic salmon from different regions, and are entirely consistent with a growing body of research using similar genetic methods being conducted on Pacific salmon. It is clear that salmon migrate to distant, stock-specific locations at sea, despite never having been to these regions before, and having no older members of their cohort to lead them. The environmental conditions that they encounter in their respective locations will affect their access to food, hence growth, but also their exposure to predators and intercepting fisheries. Thus migratory routes are of great consequence for the persistence and recovery of salmon stocks, in addition to the marvel of animal orientation that they reflect.”

According to Dr Niall Ó Maoiléidigh of the Marine Institute and a co-author on the paper, “Precise information on migration routes and timing are crucial for research into highly migratory marine species especially as the main factors causing population declines may be unknown.”

Dr Ciaran Kelly, Director of Fisheries and Ecosystem Services at the Marine Institute said, "The Marine Institute is pleased to see the contribution of its scientists and infrastructure to this project come to fruition. The findings of this study are very important for the management and conservation of salmon in the pelagic marine ecosystem."

A flotilla is steaming up the river Liffey today in the next stage of a marine wildlife campaign to secure legal protection for basking sharks in these waters.

Over 7,000 people have already voiced support for the Save Our Sharks campaign, which aims to deliver a letter personally to Minister of State Malcolm Noonan.

The letter highlights the need for legal protection of the world’s second-largest shark and fish – known as Liabhán chor gréine, or the “great fish of the sun” – within Irish territorial waters.

In May of this year, Social Democrat TD and former marine biologist Jennifer Whitmore proposed amending the Wildlife Act (1976) to include the basking shark.

This would provide legal protection to the shark in Irish territorial waters.

Scientists signed an open letter to Government last month, explaining that Irish coastal waters are “one of the few places globally” where basking sharks “regularly and predictably occur on the surface close to shore”.

“This surface swimming behaviour is the root of its deep cultural connections with western Irish coastal and island communities,” the scientists said.

The number of breeding individuals has been estimated at approximately 8,000-10,000 worldwide, the majority of which are in the northeast Atlantic.

The scientists believe section 23 of the Wildlife Act should be amended to protect the endangered species.

Celebrating Irish sharks of all shapes and sizes for Shark Awareness Day

Today, 14th July, the Marine Institute is recognising sharks of all shapes and sizes for Shark Awareness Day. Irish waters are home to 71 species of shark, skates and rays, 58 of which have been studied in detail and listed on the Ireland Red List of Cartilaginous fish. Irish sharks range from small Sleeper sharks, Dogfish and Catsharks, to larger species like Frilled, Mackerel and Cow sharks, all the way to the second largest shark in the world, the Basking shark.

A HABscope, a microscope with an attached iPod using artificially intelligent software is currently being tested by scientists from the Marine Institute and the National University of Ireland, Galway to detect harmful algal bloom species (HABs) in Irish waters. The pilot study is part of an international collaboration with the National Oceanic and Atmospheric Administration NOAA in the USA.

The HABscope was recently used on board the Marine Institute’s RV Celtic Voyager as part of a dedicated harmful phytoplankton survey (DINO21) in the Celtic Sea led by Dr Robin Raine of NUI, Galway. Data collected from this pilot study will contribute to the PhD research being conducted by Catherine Jordan from NUI, Galway as part of the Marine Institute’s Cullen Scholarship Programme.

Ocean colour satellite imagery, combined with the HABscope system, provides scientists with a ‘bird’s eye view’ of the ocean and may provide early detection and monitoring of phytoplankton blooms. Daily imagery is used to track the bloom’s movement using specifically designed algorithms that calculate the reflectance of light off the ocean surface.

The HABscope, developed by NOAA with funding from NASA, consists of a microscope with an iPod attached, embedded with artificially intelligent software to identify the swimming pattern of the phytoplankton Karenia. Results are returned instantly on whether the genre of phytoplankton is present in the water sample.

Ms Catherine Jordan said, “When phytoplankton appears in high numbers, and depending on the type of phytoplankton, they can produce green and dark red hues in the water known as 'algal blooms'. As these blooms can sometimes be visible from space, satellites provide a useful tool in monitoring the location and extent of these blooms. In most cases, phytoplankton blooms are of benefit to the ecosystem, but a small proportion of phytoplankton species produce toxins which may affect other marine life.”

“This is the first time that the HABscope has been tested outside of the United States,” Ms Jordan added. “Using the HABscope alongside satellite technology may help to provide early wide-scale warnings of the presence of harmful algal blooms. HABS can have an impact on industries such as aquaculture, fisheries and tourism, so it is important to be able to detect, monitor, track and forecast the development and movement of HABs in real-time.”

Karenia mikimotoi is a naturally occurring phytoplankton species that occasionally can form dense blooms off the Irish coast. These “Red-Tides” can sometimes cause the seawater to discolour and can even result in localised mortality of a range of marine animals. The Marine Institute monitors our coastal waters for this species as part of the National Phytoplankton Monitoring Programme. It is thought Karenia overwinter in low numbers as motile cells and when favourable conditions arrive in early to late summer they can form these blooms.

As part of the recent survey on board the RV Celtic Voyager, Karenia was detected offshore in one area at a cell density of 250,000 cells per litre in a thin sub-surface layer, analogous to an underwater cloud. The HABscope was used successfully with samples from this layer and its performance is currently being evaluated.

Despite causing occasional impacts on marine animals, Karenia has no impact on human health and is a common species in Irish coastal waters at this time of the year. The Marine Institute programme analyses water samples from around the coast of Ireland to identify any harmful or nuisance phytoplankton, and to monitor their impact on shellfish and finfish in particular.

“Subterranean estuaries” may be critical in managing sustainable fishing and aquaculture, according to new research.

Subterranean estuaries may be invisible to the naked eye, but may be very important in the ecology of coastal systems, the research by Trinity College Dublin and the Marine Research Institute of the Spanish Research Council in Vigo, Galicia, Spain has found.

They may also filter pollutants – some of which have been slowly travelling to sea for decades having leached from agricultural soils.

The researchers uncovered subterranean estuaries in the Ria de Vigo in Galicia -one of the most productive coastal ecosystems in Europe and leader in bivalve production for human consumption.

They assessed their importance to the coastal environment, and estimated that almost 25% of the continental freshwater discharged to the Ria de Vigo comes from these subterranean sources.

“Bivalve aquaculture is a strategic, expanding sector in Irish sustainable development and features highly in the national plans to diversify food production”, Carlos Rocha, professor in environmental change at Trinity College, Dublin’s school of natural sciences said.

“While our work was conducted in the Ria de Vigo, this area was carefully selected because of its capability to support aquaculture and its biogeographic similarity to parts of the Irish coastline,” Prof Rocha said.

“These subterranean estuaries have a high capability to filter out pollutants, like fertilisers, from freshwater. Given the extent to which they supply large ecosystems with incoming freshwater, they have a much more important role to play than many would have believed,” he added.

NUI Galway has previously conducted research on subterranean streams in the limestone-rich Burren area of Co Clare and their influence on Galway Bay.

The new research has just been published in open access in Frontiers in Marine Science (https://doi.org/10.3389/fmars.2021.626813) and Limnology and Oceanography (https://doi.org/10.1002/lno.11733).

Most plastic and microplastic in the marine environment comes from the agriculture sector, shipping and the fishing industry, a report by Galway-Mayo Institute of Technology (GMIT) researchers says.

Plastic seed coatings; spreading of sludges from wastewater treatment plants and the use of plastic mulching are key pollutants, while the study recorded 1816 containers from ships lost at sea in 2020, along with abandoned, lost, and discarded fishing gear.

Some of the plastic pollution is also a contributor to greenhouse gases, as in low density polyethylene in plastic milk bottles and shopping bags when exposed to solar radiation.

Microplastics - mainly fibres from clothing - threaten the food chain from its plankton base to the largest marine mammals.

GMIT microplastic researchers Dr João FriasGMIT microplastic researcher Dr João Frias

Unless addressed, 99% of all seabirds will have plastic in their digestive systems by 2050, the study says. All marine turtle species are impacted by plastic pollution through ingestion and/or entanglement.

The report compiled by members of the marine microplastic research team in the Marine and Freshwater Research Centre (MFRC) at Galway-Mayo Institute of Technology (GMIT), and Mal Deegan Productions in Dublin makes a number of recommendations.

Dr Róisín NashDr Róisín Nash GMIT microplastic researcher

It points out that the plastic pollution problem is a "complex multi-stakeholder process with many cross-sector linkages which cannot be successfully addressed in isolation".

The Irish public believes more action needs to be taken to improve the health of the ocean, according to results from Ireland’s first Ocean Citizen Survey.

More than 1,000 people across the island of Ireland completed the Ocean Citizen Survey in 2020 and shared their views on current marine issues and priorities for the protection of the marine environment. The online survey was developed by the Marine Institute and the European Commission to encourage the people of Ireland to contribute to the EU Mission for Healthy Oceans, Seas, Coastal and Inland Waters.

92% of survey respondents strongly agreed that more action needs to be taken to improve the health of the ocean. The respondents strongly agreed (85%) that human actions are damaging the ocean and that the health of the ocean and their own health is connected (67%).

"89% thought the establishment of a European Ocean Agency was a good idea"

“The Irish public care strongly about the ocean and are important stakeholders in planning for its future,” said Dr Niall McDonough, Director of Policy, Innovation and Research Support at the Marine Institute. “It is valuable to have a current understanding of the Irish public’s perceptions and concerns which can be used to inform future research activities associated with these initiatives and policy developments in Ireland, and in Europe.”

The survey also asked the public which 15 marine environmental issues they were most concerned about, and ‘pollution at the coast or in the sea’ was the issue that was most frequently selected amongst the top three. From 14 suggested climate change and marine policy issues, the policy area that was selected the most frequently by the respondents amongst their top three for prioritisation by the European Union was ‘regulating the production, use and disposal of plastic to reduce marine plastic pollution’.

Survey results also indicate that 67% of respondents strongly agreed that economic growth and job generation can be supported by the ocean, seas and inland waters.

Outputs from the Ocean Citizen Survey will be used to inform the preparation of the next National Marine Research and Innovation Strategy, which will commence later this year. Citizen participation is also an important component of the forthcoming Horizon Europe Framework Programme, spanning 2021 to 2027. The information from this survey will feed into the further planning of the Mission on Healthy Oceans, Seas, Inland and Coastal Waters.

Dr McDonough added, “Citizens are crucial to the design and accomplishment of the EU Mission in helping to set objectives and targets and ensuring that missions like this one, make a real difference in everybody’s lives.”

Time Limits on Mooring in Public Harbours

On the Shannon Navigation and the Shannon-Erne Waterway craft may berth in public harbours for five consecutive days or a total of seven days in any one month.

On the Erne System, revised Bye Laws state that: No master or owner shall permit a vessel, boat or any floating or sunken object to remain moored at or in the vicinity of any public mooring, including mooring at any other public mooring within 3 kilometres of that location, for more than 3 consecutive days and shall not moor at that same mooring or any other public mooring within 3 kilometres of that location within the following 3 consecutive days without prior permission by an authorised official.

Winter Mooring on the Shannon Navigation and Shannon Erne Waterway

Winter mooring may be availed of by owners during the period 1 Nov to 31 Mar by prior arrangement and payment of a charge of €63.50 per craft. Craft not availing of Winter Mooring must continue to comply with the “5 Day Rule”. Winter Mooring applications should be completed online at : https://www.waterwaysireland.org/online-services/winter-moorings-booking

Owners should be aware that electricity supply and water supply to public moorings is disconnected for the winter months. This is to protect against frost damage, to reduce running costs and to minimise maintenance requirements during the winter months.

Vessel owners are advised that advance purchasing of electricity on the power bollards leading up to the disconnection date should be minimal. Electricity credit existing on the bollards will not be recoverable after the winter decommissioning date. Both services will be reinstated prior to the commencement of the next boating season.

Smart Cards

Waterways Ireland smart cards are used to operate locks on the Shannon Erne Waterway, to access the service blocks, to use the pump-outs along the navigations, to avail of electrical power at Waterways Ireland jetties.

Berthing in Public Harbours

Masters are reminded of the following:

  • Equip their vessel with mooring lines of appropriate length and strength and only secure their craft to mooring bollards and cleats provided for this purpose.
  • Ensure the available berth is suitable to the length of your vessel, do not overhang the mooring especially on finger moorings on floating pontoon moorings.
  • Ensure mooring lines, electric cables and fresh water hoses do not create a trip hazard on public jetties for others users.
  • Carry sufficient fenders to prevent damage to your own vessel, other vessels and WI property.
  • Allow sufficient space between your vessel and the vessel ahead /astern (c.1m) for fire safety purposes and /or to recover somebody from the water.
  • Do not berth more than two vessels side by side and ensure there is safe access/egress at all times between vessels and onto the harbour itself.
  • Do not berth in such a way to prevent use of harbour safety ladders, slipways or pump-outs.
  • Do not allow the bow of your vessel to overhang the walkway of a floating mooring thus creating a hazard for others with an overhanging anchor or bow fendering.
  • Animals are not allowed to be loose or stray at any time.
  • Harbour and jetty infrastructure such as railings, power pedestals, fresh water taps, electric light poles, safety bollards, ladders etc are not designed for the purpose of mooring craft , they will not bear the strain of a vessel and will be damaged.
  • At Carrybridge on the Erne System, Masters of vessels are not permitted to use stern on mooring. Masters of vessels must use the mooring fingers for mooring of vessels and for embarkation / disembarkation from vessels.

Passenger Vessel Berths

Masters of vessels should not berth on passenger vessel berths where it is indicated that an arrival is imminent. Passenger vessels plying the navigations generally only occupy the berths to embark and disembark passengers and rarely remain on the berths for extended periods or overnight.

Lock Lead-in Jetties

Lead-in jetties adjacent to the upstream and downstream gates at lock chambers are solely for the purpose of craft waiting to use the lock and should not be used for long term berthing.

Vessel Wake

Vessel wake, that is, the wave generated by the passage of the boat through the water, can sometimes be large, powerful and destructive depending on the hull shape and engine power of the vessel. This wake can be detrimental to other users of the navigation when it strikes their craft or inundates the shoreline or riverbank. Masters are requested to frequently look behind and check the effect of their wake / wash particularly when passing moored vessels, on entering harbours and approaching jetties and to be aware of people pursuing other activities such as fishing on the riverbank.

Speed Restriction

A vessel or boat shall not be navigated on the Shannon Navigation at a speed in excess of 5 kph when within 200 metres of a bridge, quay, jetty or wharf, when in a harbour or canal or when passing within 100 metres of a moored vessel or boat.

Vessels navigating the Shannon-Erne Waterway should observe the general 5 kph speed limit which applies along the waterway. This is necessary in order to prevent damage to the banks caused by excessive wash from vessels.

Vessels navigating the Erne System should observe the statutory 5kt / 6mph / 10kph speed limit areas.

A craft on the Royal and Grand canals shall not be navigated at a speed in excess of 6km per hour.

A craft on the Barrow Navigation shall not be navigated at a speed in excess of 11km per hour except as necessary for safe navigation in conditions of fast flow.

Bank Erosion

Narrow sections of all the navigations are particularly prone to bank erosion due to the large wash generated by some craft. Masters are requested to be vigilant and to slow down to a speed sufficient to maintain steerage when they observe the wash of their craft inundating the river banks.

Unusual Waterborne Activity

Unusual waterborne vessels may be encountered from time to time, such as, hovercraft or amphibious aircraft / seaplanes. Masters of such craft are reminded to apply the normal “Rule of the Road” when they meet conventional craft on the water and to allow extra room to manoeuvre in the interest of safety.

Sailing Activity

Mariners will encounter large numbers of sailing dinghies from late June to August in the vicinity of Lough Derg, Lough Ree and Lower Lough Erne. Sailing courses are marked by yellow buoys to suit weather conditions on the day. Vessels should proceed at slow speed and with due caution and observe the rules of navigation when passing these fleets, as many of the participants are junior sailors under training.

Rowing

Mariners should expect to meet canoes and vessels under oars on any part of the navigations, but more so in the vicinity of Athlone, Carrick-on-Shannon, Coleraine, Enniskillen and Limerick. Masters are reminded to proceed at slow speed and especially to reduce their wash to a minimum when passing these craft as they can be easily upset and swamped due to their very low freeboard and always be prepared to give way in any given traffic situation.

Canoeing

Canoeing is an adventure sport and participants are strongly recommended to seek the advice of the sport’s governing bodies i.e Canoeing Ireland and the Canoe Association of Northern Ireland, before venturing onto the navigations.

Persons in charge of canoes are reminded of the inherent danger to these craft associated with operating close to weirs, sluice gates, locks and other infrastructure particularly when rivers are in flood and large volumes of water are moving through the navigations due to general flood conditions or very heavy localised precipitation e.g. turbulent and broken water, stopper waves. Shooting weirs is prohibited without prior permission of Waterways Ireland.

Canoeists should check with lockkeepers prior entering a lock to ensure passage is done in a safe manner. Portage is required at all unmanned locks.

Canoe Trail Network – "Blueways"

Masters of powered craft are reminded that a canoe trail network is being developed across all navigations and to expect more organised canoeing along these trails necessitating slow speed and minimum wash when encountering canoeists, rowing boats etc

Rockingham and Drummans Island Canals – Lough Key

It is expected that work on Rockingham and Drummans Island Canals on Lough Key will be completed in 2021. Access to these canals will be for non-powered craft only, eg canoes, kayaks, rowing boats.

Fast Powerboats and Personal Watercraft (Jet Skis)

Masters of Fast Powerboats (speed greater than 17kts) and Personal Watercraft (i.e.Jet Skis) are reminded of the inherent dangers associated with high speed on the water and especially in the confines of small bays and narrow sections of the navigations. Keeping a proper look-out, making early alterations to course and /or reducing speed will avoid conflict with slower vessels using the navigation. Personal Watercraft are not permitted to be used on the canals.

Towing Waterskiers, Wakeboarders, Doughnuts etc

Masters of vessels engaged in any of these activities are reminded of the manoeuvring constraints imposed upon their vessel by the tow and of the added responsibilities that they have to the person(s) being towed. These activities should be conducted in areas which are clear of conflicting traffic. It is highly recommended that a person additional to the master be carried to act as a “look-out” to keep the tow under observation at all times.

Prohibition on Swimming

Swimming in the navigable channel, particularly at bridges, is dangerous and is prohibited due to the risk of being run over by a vessel underway in the navigation.

Age Restrictions on operating of powered craft

In the Republic of Ireland, Statutory Instrument 921 of 2005 provides the legal requirements regarding the minimum age for operating of powered craft. The Statutory Instrument contains the following requirements:

- The master or owner of a personal watercraft or a fast power craft shall take all reasonable steps to ensure that a person who has not attained the age of 16 years does not operate or control the craft

- The master or owner of a pleasure craft powered by an engine with a rating of more than 5 horse power or 3.7 kilowatts shall take all reasonable steps to ensure that a person who has not attained the age of 12 years does not operate or control the craft.

Lifejackets and Personal Flotation Devices (PFDs)

Lifejackets and PFD’s are the single most important items of personal protective equipment to be used on a vessel and should be worn especially when the vessel is being manoeuvred such as entering / departing a lock, anchoring, coming alongside or departing a jetty or quayside.

In the Republic of Ireland, Statutory Instrument 921 of 2005 provides the legal requirements regarding the wearing of Personal Flotation Devices. The Statutory Instrument contains the following requirements:

- The master or owner of a pleasure craft (other than a personal watercraft) shall ensure, that there are, at all times on board the craft, sufficient suitable personal flotation devices for each person on board.

- A person on a pleasure craft (other than a personal watercraft) of less than 7 metres length overall shall wear a suitable personal flotation device while on board an open craft or while on the deck of decked craft, other than when the craft is made fast to the shore or at anchor.

- The master or owner of a pleasure craft (other than a personal watercraft) shall take all reasonable steps to ensure that a person who has not attained the age of 16 years complies with paragraph above.

- The master or owner of a pleasure craft (other than a personal watercraft), shall take all reasonable steps to ensure that a person who has not attained the age of 16 years wears a suitable personal flotation device while on board an open craft or while on the deck of a decked craft other than when it is made fast to the shore or at anchor.

- The master or owner of a pleasure craft (other than a personal watercraft) shall take all reasonable steps to ensure that a person wears a suitable personal flotation device, at all times while – (a) being towed by the craft, (b) on board a vessel or object of any kind which is being towed by the craft.

Firing Range Danger Area – Lough Ree

The attention of mariners is drawn to the Irish Defence Forces Firing Range situated in the vicinity of buoys No’s 2 and 3, on Lough Ree on the Shannon Navigation. This range is used regularly for live firing exercises, throughout the year, all boats and vessels should stay clear of the area marked with yellow buoys showing a yellow "X" topmark and displaying the word "Danger".

Shannon Navigation, Portumna Swing Bridge Tolls

No attempt should be made by Masters’ of vessels to pay the bridge toll while making way through the bridge opening. Payment will only be taken by the Collector from Masters when they are secured alongside the jetties north and south of the bridge.

Navigating from Killaloe to Limerick on the Shannon Navigation

The navigation from Killaloe to Limerick involves passage through Ardnacrusha locks, the associated headrace and tailrace and the Abbey River into Limerick City. Careful passage planning is required to undertake this voyage. Considerations include: lock passage at Ardnacrusha, water flow in the navigation, airdraft under bridges on Abbey River in Limerick, state of tide in Limerick

Users are advised to contact the ESB Ardnacrusha hydroelectric power station (00353 (0)87 9970131) 48 hours in advance of commencing their journey to book passage through the locks at Ardnacrusha. It is NOT advised to undertake a voyage if more than one turbine is operating (20MW), due to the increased velocity of flow in the navigation channel, which can be dangerous. To ascertain automatically in real time how many turbines are running, users can phone +353 (0)87 6477229.

For safety reasons the ESB has advised that only powered craft with a capacity in excess of 5 knots are allowed to enter Ardnacrusha Headrace and Tailrace Canals.

Passage through Sarsfield Lock should be booked on +353-87-7972998, on the day prior to travel and it should be noted also that transit is not possible two hours either side of low water.

A Hydrographic survey in 2020 of the navigation channel revealed that the approach from Shannon Bridge to Sarsfield Lock and the Dock area has silted up. Masters of vessels and water users are advised to navigate to the Lock from Shannon bridge on a rising tide one or two hours before High Tide.

Lower Bann Navigation

The attention of all users is drawn to the “Users Code for the Lower Bann”, in particular to that section covering “Flow in the River” outlining the dangers for users both on the banks and in the navigation, associated with high flow rates when the river is in spate. Canoeists should consult and carry a copy of the “Lower Bann Canoe Trail” guide issued by the Canoe Association of Northern Ireland. Users should also contact the DfI Rivers Coleraine, who is responsible for regulating the flow rates on the river, for advisory information on the flow rates to be expected on any given day.

DfI Rivers Coleraine. Tel: 0044 28 7034 2357 Email: [email protected]

Lower Bann Navigation – Newferry – No wake zone

A No Wake Zone exists on the Lower Bann Navigation at Newferry. Masters of vessels are requested to proceed at a slow speed and create no wake while passing the jetties and slipways at Newferry.

Overhead Power Lines (OHPL) and Air draft

All Masters must be aware of the dangers associated with overhead power lines, in particular sailing vessels and workboats with cranes or large air drafts. Voyage planning is a necessity in order to identify the location of overhead lines crossing the navigation.

Overhead power line heights on the River Shannon are maintained at 12.6metres (40 feet) from Normal Summer level for that section of navigation, masters of vessels with a large air draft should proceed with caution and make additional allowances when water levels are high.

If a vessel or its equipment comes into contact with an OHPL the operator should NOT attempt to move the vessel or equipment. The conductor may still be alive or re-energise automatically. Maintain a safe distance and prevent third parties from approaching due to risk of arcing. Contact the emergency services for assistance.

Anglers are also reminded that a minimum ground distance of 30 metres should be maintained from overhead power lines when using a rod and line.

Submarine Cables and Pipes

Masters of vessels are reminded not to anchor their vessels in the vicinity of submarine cables or pipes in case they foul their anchor or damage the cables or pipes. Look to the river banks for signage indicating their presence.

Water Levels - Precautions

Low Water Levels:

When water levels fall below normal summer levels masters should be aware of:

Navigation

To reduce the risk of grounding masters should navigate on or near the centreline of the channel, avoid short cutting in dog-legged channels and navigating too close to navigation markers.

Proceeding at a slow speed will also reduce “squat” effect i.e. where the vessel tends to sit lower in the water as a consequence of higher speed.

Slipways

Reduced slipway length available under the water surface and the possibility of launching trailers dropping off the end of the concrete apron.

More slipway surface susceptible to weed growth requiring care while engaged in launching boats, from slipping and sliding on the slope. Note also that launching vehicles may not be able to get sufficient traction on the slipway once the craft is launched to get up the incline.

Bank Erosion

Very dry riverbanks are more susceptible to erosion from vessel wash.

Lock Share

Maximising on the number of vessels in a lock will ensure that the total volume of water moving downstream is decreased. Lock cycles should be used for vessels travelling each way.

High Water Levels:

When water levels rise above normal summer level masters should be aware of:

Navigation

Navigation marks will have reduced height above the water level or may disappear underwater altogether making the navigable channel difficult to discern.

In narrow sections of the navigations water levels will tend to rise more quickly than in main streams and air draft at bridges will likewise be reduced.

There will also be increased flow rates particularly in the vicinity of navigation infrastructure such as bridges, weirs, locks etc where extra care in manoeuvring vessels will be required.

Harbours and Jetties

Due care is required in harbours and at slipways when levels are at or near the same level as the harbour walkways' as the edge will be difficult to discern especially in reduced light conditions. It is advised that Personal Flotation Devices be worn if tending to craft in a harbour in these conditions.

Slipways

Slipways should only be used for the purpose of launching and recovering of water craft or other objects from the water. Before using a slipway it should be examined to ensure that the surface has sufficient traction/grip for the intended purpose such as launching a craft from a trailer using a vehicle, that there is sufficient depth of water on the slipway to float the craft off the trailer before the concrete apron ends and that the wheels of the trailer do not drop off the edge of the slipway. That life-saving appliances are available in the vicinity, that the vehicle is roadworthy and capable of coping with the weight of the trailer and boat on the incline. It is recommended that slipway operations are conducted by two persons.

Caution to be Used in Reliance upon Aids to Navigation

The aids to navigation depicted on the navigation guides comprise a system of fixed and floating aids to navigation. Prudent mariners will not rely solely on any single aid to navigation, particularly a floating aid to navigation. With respect to buoys, the buoy symbol is used to indicate the approximate position of the buoy body and the ground tackle which secures it to the lake or river bed. The approximate position is used because of the practical limitations in positioning and maintaining buoys in precise geographical locations. These limitations include, but are not limited to, prevailing atmospheric and lake/river conditions, the slope of and the material making up the lake/river bed, the fact that the buoys are moored to varying lengths of chain, and the fact that the buoy body and/or ground tackle positions are not under continuous surveillance. Due to the forces of nature, the position of the buoy body can be expected to shift inside and outside the charted symbol.

Buoys and perches are also moved out of position or pulled over by those mariners who use them to moor up to instead of anchoring. To this end, mariners should always monitor their passage by relating buoy/perch positions with the published navigation guide. Furthermore, a vessel attempting to pass close by always risks collision with a yawing buoy or with the obstruction that the buoy or beacon/perch marks.

Masters of Vessels are requested to use the most up to date Navigation guides when navigating on the Inland Waterways.
