The work of a marine scientist and conservationist who pioneered a response to the Torrey Canyon supertanker environmental disaster of 1967 has been marked by the Oxford Dictionary of National Biography.

The late Stella Turk, a leading expert on molluscs on the British and Irish coasts, is among 241 people to have been acknowledged as history “shapers” in the publication’s new edition.

Turk ( née Phillips) was born in St Mary’s on the Scilly isles in 1925, and developed an interest in natural history from a young age. After she married Frank Archibald Turk, a conchologist and marine life expert, she further developed her expertise on the Cornish coast.

The Oxford Dictionary of National Biography entry records how the Torrey Canyon disaster of March 1967 had an enormous influence on her work

The supertanker struck a reef between Cornwall and Scilly and leaked some 30 million gallons of crude oil into the sea, polluting a large section of the Cornish coast.

Turk observed that “the rock pools were stripped bare” , and pointed out that quantifying the losses was made difficult by a lack of records of the pre-existing flora and fauna.

“ This seems to have focused the Turks even more sharply on the task of surveying and compiling lists of biological records for the county, continuing their extensive fieldwork, and corresponding with numerous national experts for assistance in specialist groups,” the Oxford publication says.

Turk founded the Cornish Biological Records Unit, which for many years she ran from her home in Reskadinnick, and later worked closely with the Cornish Wildlife Trust.

From 1990, she pioneered what is now Cornwall Wildlife Trust's Marine Strandings Network, which is of international standing.

In 2019, two years after her death in 2017, a research facility at the University of Exeter's Penryn Campus was named after her.

The Oxford Dictionary of National Biography is the national record of men and women who have shaped British history, worldwide, from prehistory to the year 2017. From January 2021 the dictionary includes biographies of 64,071 individuals, written by over 14,000 contributors.

Irish cold-water corals can survive in extreme conditions within Ireland’s largest submarine canyon on the Porcupine Bank, a new study has found.

The coral even grows on precipices of high cliffs, and can withstand sea current speed of over 114 centimetres per second, according to the study published today in the science journal Nature.

This is the highest current speed ever recorded in a cold water habitat, according to University College Cork(UCC) scientist Dr Aaron Lim who led the research.

Dr Lim’s team used the Holland 1 remotely operated vehicle (ROV) on the State research ship Celtic Explorer to explore how coral are living in the Porcupine Bank Canyon which is 3,500 metres deep.

He was part of the 2018 expedition which explored and mapped the canyon some 320 km west of Kerry, finding it full of cold-water corals forming reefs and mounds which create a rim on the lip of the canyon.

This latest expedition found coral in a range of deep marine settings.

The scientists had to use deep marine monitoring stations and three-dimensional reconstructions as part of the work. .

“These cold-water corals are growing at the very edge of a near-vertical cliff face, in Ireland’s largest submarine canyon some 850 m below the surface in very intense conditions. They’re quite literally living on the edge,” Dr Lim said.

As he explained, cold-water corals help to form deep-water reefs and mounds which can range from as little as ten metres to over 100 m high.

Some coral mounds have existed offshore Ireland for 2.6 million years, he said. 

“Some of these habitats were predominantly alive, while others were mostly dead and so the aim of the study was to understand what is driving this?” Dr Lim said.

UCC marine geologist Luke O’Reilly described the canyon as “a strange-place; deep, dark and cold but full of life”.

“Together with the Marine Institute, we developed a monitoring system which could withstand these pressures and conditions for months at a time,” O’Reilly said.

Prof Andy Wheeler, head of UCC’s school of biological, earth and environmental sciences, noted that the coral can cope with the strong sea currents, but tend to feed when it slows down – such as when the tide turns. 

The team have recently deployed monitoring stations in the canyon to gather information on survival over longer time scales. 

The research was funded by Science Foundation Ireland and Horizon 2020, with co-funding by the Marine Institute and Geological Survey, Ireland. Shiptime was funded by the Marine Institute's National Shiptime Programme.

Two researchers from Trinity College, Dublin (TCD) are among leaders of a €10.4 million project to assess the significance of marine resource exploitation over the past 2,000 years.

Archaeology, history and environmental science experts will collaborate in the “4-Oceans” project, funded by the European Research Council.

It has been billed as the “first-ever globalised evaluation” of the role of marine resources on human societies over two millennia.

TCD professor of environmental history Poul Holm and assistant professor of medieval environmental history Francis Ludlow are among a four-strong team of principal investigators.

This project combines expertise in marine environmental history, climate history, natural history, geography, historical ecology and zooarchaeology - spanning the humanities, natural sciences and social sciences.

Working with Prof Holm and Prof Ludlow as project leaders will be University of Cambridge medieval archaeology expert James H Barrett and NOVA University, Lisbon assistant professor Cristina Brito.

Prof Holm said the €10.4 million grant would facilitate “an unparalleled understanding of humanity’s recent interactions with the oceans”.

“Specifically, combining history and archaeology with marine science and socioeconomics, the 4-Oceans team will examine when and where marine exploitation was of significance to human society,”he said.

It would also explore “how major socio-economic, cultural, and environmental forces variously constrained and enabled marine exploitation”.

It would also research “the consequences of marine resource exploitation for societal development”, he said.

His colleague, Prof Ludlow said that “long-term data and an understanding of changes in ecosystems and human behaviour over many centuries is critical to informing the continued development of the UN’s Sustainable Development Goals and the Decade for the Oceans”.

So far, the historical dimension has been missing from this, he said, and the 4-Oceans project would “introduce much-needed chronological depth... through the understanding of our past”, he said.

Professors Holm and Ludlow will oversee €5.4 million of the €10.4 million research funding total allocated to 4-Oceans.

So far, TCD researchers have secured 37 European Research Council investigator grants to the value of about 68 million euro during the course of the EU’s Horizon 2020 framework for research and innovation, which is worth nearly €80 billion in total over six years.

TCD Provost Dr Patrick Prendergast welcomed the securing of the latest award.

As hopes fade of Fungie’s return to Dingle, research suggests that “missing” dolphins are more likely to have migrated than died.

Dolphins in the Shannon estuary which were initially presumed to have perished had in fact moved to nearby bays, according to research published by the Irish Whale and Dolphin Group (IWDG).

The study by Kim Ellen Ludwig of Galway-Mayo Institute of Technology (GMIT) found that the “missing” dolphins had “emigrated” to Tralee and Brandon bays in Kerry, south of the Shannon estuary.

The Shannon estuary’s population of around 140 dolphins provided a good sample for the study, which Ms Ludwig conducted in collaboration with the IWDG.

The IWDG – a registered charity founded by Dr Simon Berrow in 1990 - has been monitoring the Shannon bottlenose dolphins since 1993. It constitutes the longest running whale or dolphin study in Ireland.

The group recently explored its 27-year old identification dataset to see if it could answer the question as to when to consider a dolphin as “dead” rather than missing.

Dolphins and whales are highly mobile, ranging thousands of kilometres.

Survival of young dolphins or calves is easier to monitor when they are dependent on their mothers for survival and is more difficult when calves are weaned.

The study with Ms Ludwig indicated that survival rate was 95.6% for “well-marked individual dolphins”- which means around 4.4% of adult dolphins die each year.

“For less well-marked individuals, survival increases to 5.8%, due to the higher chance a dolphin is “missed” during surveys,” it says.

The IWDG says that Ms Ludwig’s work highlights “a really important confounding factor, that of emigration outside the Shannon estuary to adjacent Tralee and Brandon bays”.

The dolphins had been presumed dead as these two bays are not routinely sampled during monitoring surveys.

Only by extending their surveys, did the IWDG realise that the dolphins were alive and well, and had extended their range.

Scientists with the IWDG are now recommending that the boundary of the lower river Shannon special area of conservation be extended to protect the important habitats of the bottlenose dolphins.

The group also suggests the area could be designated as a marine protected area as an alternative strategy.

In relation to Fungie, estimated to be 37 years old, the IWDG says that “as the time increases without a sighting and the search effort continues", it is "more likely" that he is dead rather than just simply missing.

However “his legacy will live on for years”, it says.

Minister for Agriculture, Food and the Marine, Charlie McConalogue T.D., has earmarked the purchase of a new marine research vessel for the State in his Department's 2021 Budget.

As Afloat previously reported, €25m was allocated in Tuesday's budget to progress the construction of the vessel.

In making the announcement Minister McConalogue said: "The budget provision will allow the Marine Institute to progress construction on the replacement of the 21-year-old Celtic Voyager with a new 54m modern research vessel that will provide critical national infrastructure to enable Ireland to address the considerable challenges of Brexit and the Common Fisheries Policy as well as climate-induced impacts on our oceans."

Welcoming the news Dr Paul Connolly, CEO Marine Institute said: "The Marine Institute is delighted that work can continue on the replacement for the Celtic Voyager. This new vessel will enable Ireland to develop the best scientific advice possible to maximise economic opportunities for our coastal industries and communities and ensure a sustainable resource for them".

The construction of the new national research vessel will continue in 2021 with the build process expected to be completed in summer 2022. Spanish shipyard Astilleros Armon Vigo S.A. were awarded the contract to build the new marine research vessel for Ireland last year, following an extensive EU tender process.

Set to be one of the most advanced marine research vessels in the world, Ireland's new marine research vessel will enable Ireland to undertake critical research work to deepen our understanding of our oceans and our natural resources.

The new vessel will be able to go to sea for at least 21 days at a time and will be designed to operate in harsh sea conditions. Based in Galway, the vessel will be used by the Marine Institute, other State agencies and universities to undertake fisheries research, oceanographic and environmental research, seabed mapping and other multidisciplinary surveys. It will also maintain and deploy weather buoys, observational infrastructure and our Remotely Operated Vehicle (ROV Holland I).

The new vessel will be a sister ship to the State's largest research ship, the 65m RV Celtic Explorer and will replace the RV Celtic Voyager. The two Marine Institute research vessels currently in operation (RV Celtic Explorer and RV Celtic Voyager) are among the most intensively used research vessels in the world. The Marine Institute's RV Celtic Voyager is Ireland's first purpose built research vessel. It has been utilised heavily since its delivery 21 years ago and has been vital in providing marine scientists, researchers and its crew members, with many years of valued experience at sea, expanding and strengthening marine science in Ireland to help inform decisions affecting our ocean.

According to Dr Connolly, "The significantly enhanced capabilities of the vessel will help our researchers, educators, students and the public gain a deeper understanding of the ocean. Most importantly it will facilitate work that will support many of the projects outlined in the Programme for Government including fisheries assessment, offshore renewable energy, marine spatial planning, marine protected areas and research in the area of blue carbon."

Capital funding of €1.5m has also been allocated to the Marine Institute in Budget 2021, and funding for national research investment in marine-related activities will align with the Programme for Government and the needs of decision-makers.

Speaking about the additional funding announced in Budget 2021 Dr Connolly, said that "Research investments will add value to the core services provided by the Marine Institute to their national and international clients, including the Department of Agriculture, Food and the Marine. This new research data and knowledge will strengthen our scientific and technical advice to better inform decision-making on the sustainable management of our ocean and seas".

In 2021, the Marine Institute plans to fund a call for a large-scale project for researchers to investigate the potential for carbon storage and sequestration in Irish waters. This was highlighted as an important priority area for the Marine Institute in the Programme for Government. The work will examine a range of potential carbon storage alternatives such as algal absorption, seagrass forestry, deep-sea sinks, seabed layering and shellfish farming.

In welcoming the research expenditure allocations announced in Budget 2021, The Minister of State at the Department of Agriculture, Food and the Marine, Martin Heydon, T.D. said that "If we are going to continue to deliver efficiency and sustainability in the years ahead, innovation will be critical". The Minister also pointed out that the combined investment in Research and Innovation by the Department, Teagasc and the Marine Institute is now over €60m annually.

The Irish Wildlife Trust (IWT) has called on Minister for Marine Charlie McConalogue and Minister of State for Biodiversity Pippa Hackett to “act swiftly” over a High Court decision that overturns a ban on fishing by vessels over 18 metres long inside the six nautical mile limit.

The Irish Whale and Dolphin Group (IWDG) has also called for a scientific study of species including sprat stocks in inshore waters.

A High Court judgment published last week found that the ban on trawling or fishing within seine nets by vessels over 18 metres in length inside the six-mile nautical limit has “no legal effect”.

Mr Justice Michael McGrath issued his judgment on foot of a judicial review of the ban which was introduced by former marine minister Michael Creed in March 2019.

The judicial review of the policy directive was taken by fishermen Tom Kennedy and Neil Minihane.

IWT campaign officer Pádraic Fogarty said that the original ban was initiated “after a public consultation in 2018 which was roundly supported by low-impact fishers in smaller boats, anglers, environmental groups and members of the public”.

“It was heralded at the time as the single most important move to protect fisheries and marine biodiversity that we have seen. There is consequently widespread anger and dismay that this has now been undone,” Mr Fogarty said in a statement.

“We’re urging ministers Hackett and McConalogue to act swiftly on this High Court decision and to tell us how the trawling ban can be reinstated on a permanent basis,” he said.

“ Until then we need to see all inshore trawling shut down so that any recovery in marine life which may have been underway is not completely undone,” Mr Fogarty said.

The IWT says that trawling for small fish such as sprat “removes the principle food source for sea life, whether its whales, dolphins or larger fish”.

“Bottom trawling, which scrapes a net across the seafloor, obliterates important habitats for fish spawning and should be phased out across our seas,” it says.

IWDG co-ordinator Dr Simon Berrow said that while he did not want to comment directly on the judgment, it was time for a “proper, robust scientific study” on sprat stocks.

“We know so little about sprat,” Dr Berrow told RTÉ Radio 1’s Seascapes on Friday night, pointing out how important the species is for whales.

The six-mile ban for larger vessels was introduced by Minister Michael Creed on 5th March 2019, and came into force on January 1st of this year.

The directive did give a derogation for fishing sprat within six nautical miles up to December 2021, “subject to any catch limits as may be determined by the minister from time to time”.

The Irish South and West Fish Producers Organisation (ISWFPO) has welcomed the judgment. Its chief executive Patrick Murphy said that “once again, we see flawed legislation being overturned in our High Court “.

“The view of IS&WFPO members remains that only a small proportion of fishing boats in our tiny Irish fishing fleet of 165 vessels of over 18 meters in length actually fish inside of the six-mile limit,” he said.

Mr Murphy concurred with the IWDG in calling for a scientific evaluation to calculate the biomass of all commercial stocks within the six-mile zone.

“Until this assessment is complete, we submit that no total allowable quota figure should be set for this important fishery,” he said.

The waters off the south coast of Ireland have been selected as the study location for Ireland’s first real-time acoustic monitoring project of large whales, with the aim to relay warning alerts to maritime traffic to reduce the risk of disturbance and ship strikes.

The Automated Cetacean Acoustics Project (ACAP) is being undertaken by Ocean Research & Conservation Ireland, a “for-impact” non-profit organisation based in Cork, in partnership with the Rainforest Connection and supported by Huawei Ireland.

Huawei Ireland is providing a research grant with technological support through its global TECH4ALL initiative. TECH4ALL is Huawei’s digital inclusion initiative, using technology, applications and skills to empower people and organisations everywhere.

90% of Ireland’s international trade travels by sea, with the South Coast of Ireland one of the busiest heavy ship shipping lanes in the world. Thousands of large container ships pass through it from Eastern Canada to Liverpool and other European ports annually, as well as additional pleasure boats, speed crafts and eco-tour operators.

The South Coast is also an important foraging, resting and reproductive habitat for 25 cetacean species (whales, dolphins and porpoise) and particularly for large Humpback, Fin and Minke whales. Heavy ship traffic places whales at an increased risk of ship strikes causing injury or even death, and also raises the ambient noise pollution affecting all the species present.

The new study will see the deployment of acoustic monitoring equipment in the Celtic Sea at locations where sightings of whales and other wildlife have been recorded. The equipment will be able to listen for movements of whales, and with the help of machine learning models to enhance data analysis, for the first time provide near real-time detection. This will provide multiple benefits - helping with the identifying and classification of species in Irish waters, their distribution and behaviour, and most importantly, the development of an early warning system that will enable ships to reduce their speed in time to lessen the considerable risk of ship strikes.

The project will see Ireland leading the way in the advancement of policy and programmes that respect and protect marine wildlife informed by near real-time data available for the first time, with the help of Rainforest Connection and Huawei Ireland. Not only will the detections be able to help inform policy and decision-makers in the establishment and management of potential marine protected areas (MPA’s), they will also be used for education and made available to the wider public to hear the symphony of cetacean sounds.

Commenting, lead researcher Emer Keaveney, Marine Mammal Ecologist, Ocean Research & Conservation Ireland said: “Recent advances in technology provide increasing opportunity to use these innovations for good and to enhance our understanding of the natural world. This is such an exciting time as now we have a chance to peer inside the secret world of whales in Irish waters, and directly improve their welfare and conservation”.

“We are a voluntary organisation that relies heavily on third party and private assistance, so we are delighted to have this opportunity to work with Huawei Ireland.”

Emer Keaveney will discuss the project via livestream as part of the annual Huawei Connect summit, which takes place in Shanghai and online between 23rd - 26th September. Emer Keaveney is the only Irish speaker at the summit, which focuses on AI, 5G and digital innovation.

Commenting on the announcement, Tony Yangxu, CEO Huawei Ireland said: “Huawei has been a trusted partner for over 16 years in Ireland, and we are excited to be supporting Ocean Conservation & Research Ireland as our very first fully funded TECH4ALL initiative in Ireland.”

“Huawei believes that no one should be left behind in the digital world and we have made it our mission to put digital inclusion front and centre of our business. Our TECH4ALL programme centers on developing digital inclusion and empowerment initiatives with measureable outcomes. One of its many purposes is to help accelerate the UN’s SDGs and we hope that this project with ORC Ireland can contribute to that.”

Ireland should have 75 per cent of its land territory mapped this year, according to the Geological Survey of Ireland (GSI).

A low-flying aircraft will gather geophysical date over counties Laois, Tipperary, Kilkenny and Waterford, and neighbouring parts of Offaly, Cork, Carlow and Kildare from September until the end of the year, weather permitting, the GSI says.

Based at Waterford airport, the survey plane will be flying at 60 metres over rural areas – about eight times the height of a two-storey house – and 240 metres over urban areas in the coming months, as approved by the Irish Aviation Authority.

The GSI is already involved in seabed mapping with the Marine Institute under the INFOMAR programme, and the Tellus Survey has been conducted on land over the last nine years.

Tellus collects geochemical and geophysical data on rocks, soil and water across Ireland. It involves airborne physical surveying using a low-flying aircraft, and ground-based geochemical surveying of soil, stream water and stream sediment.

It is currently funded under Project2040 - the National Development Plan – by the Department of Communications, Climate Action and Environment.

The department says it has “the potential to deliver positive economic, environmental and agricultural benefits by helping to assist in local environment understanding, soil management, and natural resource potential for these counties”.

Tellus project manager and senior geologist Dr James Hodgson describes it as “an important national project, providing valuable insights into the geological makeup of Ireland”.

“The data collected from the Tellus Survey helps us to sustainably manage our environment and natural resources as well as protecting public health,” he said.

The survey aircraft is a white, twin-propeller plane (as pictured), which is easily identified by its red tail and black stripe as well as the word ‘SURVEY’ and registration number C-GSGF written across both sides of the plane.

Data collected throughout the Tellus project is published and made freely available to all on the Tellus website (www.tellus.ie).

When Dr Kathy Sullivan (68) climbed out of a tiny submersible which had returned from the bottom of the Mariana Trench, none of the subsequent headlines were quite as clever as that “most vertical girl in the world” slogan coined by several of her friends.

It inspired a badge which she now wears -the first female US astronaut to walk in space and to reach the deepest known point of the world’s oceans has a sharp sense of humour. Some might say with her Irish lineage that she’d have to have – she has cousins on beautiful Beara peninsula.

Former Marine Institute chief executive Dr Peter Heffernan wisely developed that link through initiatives like the Atlantic Ocean Research Alliance when Dr Sullivan was US Under Secretary of Commerce for Oceans and Atmosphere and National Oceanic and Atmospheric Association Administrator (NOAA).

Dr Sullivan - an oceanographer and geologist - joins that panoply of individuals with Irish connections who have distinguished themselves over many centuries in the marine sphere, be it in fishing or trade, or in foreign navies, in exploration, or in technology and innovation.

The lives of many of these mostly male marine pioneers - from St Brendan to submarine designer John Philip Holland and explorers Sir Ernest Shackleton and Edward Bransfield - have been documented by late maritime historian Dr John de Courcy Ireland among others. He was often asked by colleagues at international conferences to explain why so many Irish mariners of note had to go abroad to make their name.

These academics were curious to know why there was not much more lasting “Viking influence” in Irish socio-economic activity, given that Ireland’s coastal state population was not dissimilar in size to that of Norway. The “real map of Ireland” is at least ten times the land size - as that clever Marine Institute postcard image depicts - and our Continental Shelf position on a northerly latitude is tempered by the influence of the Gulf Stream

The impact of colonisation, including deliberate efforts to suppress the Irish fishing fleet when it became too competitive, were among reasons given by Dr de Courcy Ireland during a debate on this question at a conference on “Ireland the Sea”. It was hosted by the Merriman Summer School and Bord Iascaigh Mhara in Co Clare back in 1983.

I came across the paperback record of that debate, and it was welcome distraction during a brief “Covid-19 lockdown” office tidy. Conference participant and founding Irish Skipper editor Arthur Reynolds pointed to the uneconomic reality of 900 different landing points around the coast. The fertility of this island’s soil always made agriculture a more attractive bet, he said.

Labour Party politician Justin Keating, a vet and RTÉ Head of Agricultural Programmes, posed a more complex answer. During his time as industry and commerce minister almost a decade earlier, he had attempted to set up a “Statoil” model for hydrocarbon development here. He noted that the sea provided this State with “almost an embarrassment of riches, and a superb national challenge”.

“The fact that this potential had not been realised was not due to “genetics” or “laziness”, but due in part to economics and the “horrendously expensive” costs of certain maritime development, Keating said. However, there was also a confidence factor, he argued; we were only beginning to recover from a “profound culture shock” which was “not unique to us”.

The colonial experience had touched “everywhere in the world where people were defeated by newer and superior technology, from South-East Asia to the homelands of the North American Indians,” Keating said. He outlined one First Nation response to this shock - the “ghost dance”, and suggested the Irish version of this was our “fascination with words and music.... based on their use in a magic sense, for altering consciousness and for making reality go away....”.

Magic being illusionary, the only possible “national therapy” was development of our marine potential, in his view. Without mobilisation of capital – which had fled these shores over previous centuries – we would not “mobilise technology”, he said.

That same year, a marine management system which has had devastating results for coastal states like this one was rubberstamped. Just two EU states – Ireland and Denmark - had a surplus of fish at the time of Common Fisheries Policy (CFP) formulation.

The CFP is subject to ten-yearly reviews, which now place much greater emphasis on sustainability. Brexit creates a really serious challenge, as industry organisations have outlined, yet there seems to be a reluctance here to seek a more equitable revision of the policy, based on proximity to a resource.

As the late Castletownbere fishermen and industry leader Donal O’Driscoll pointed out, the initial deal struck in favour of agricultural benefits and structural funds was never intended by our EU masters to be “cast in stone”.

EU directives on the environment have had a more positive influence, though sometimes failing to protect communities from the pressures of the market. A template for democratic planning published by the British Institution of Civil Engineers four years ago cited this State’s handling of the Corrib gas project as an example of “how not to undertake a development”.

The methodology known as Global Risk and Strategic Assessment Planning (GRASP) developed by British chartered surveyor Michael Ocock, organisational psychologist Prof Agi Oldfield and colleagues aims to avoid selective consultation or a domination of debates by “rogue stakeholders” and the “space shuttle syndrome” identified in large scale projects which have taken a wrong turn. Scottish islanders have also taught us that sustainability is not about ticking consultation boxes, but about genuine stakeholder engagement and community return.

Growing of seaweedGrowing of seaweed

Like the tide coming in and out twice a day, the sea still throws up endless opportunities for change – seaweed culture as one example, which the late British scientist Dr Eric Edwards once forecast would be far more lucrative for Ireland than salmon farming. Fascinating work by the Bantry Marine Research Station in west Cork is exploring how a type of red seaweed could also reduce methane emissions in cattle – a valuable case, if realised, of “blue meets green”.

That active Atlantic system which could turn Ireland into a “Green gulf” of renewable energy, in the words of one developer, could fuel home energy needs and bulk hydrogen exports. The 30-year strategy drawn up by the Eirwind consortium involving University College, Cork researchers Dr Val Cummins (now gone into private practice) and Dr Jimmy Murphy and industry cites the importance of prioritising the long-awaited marine planning framework and supporting legislation.

The reports by NUI Galway’s Socio-Economic Marine Research Unit which inform the government’s Harnessing Our Ocean Wealth strategy show a positive trend. It recently reported on the opportunities which coastal tourism could offer during this pandemic.

coastal tourism studyTotal expenditure by domestic tourists in coastal areas was estimated to be €698 million in 2018, which represents 35% of the total expenditure by domestic tourists that year, a new study says.

Complementing the research in third-level institutions and the efforts of the Marine Institute and BIM, there are also a plethora of individuals and non-governmental organisations who have helped to raise awareness of our maritime heritage and of our potential on the Atlantic margin.

Like Dr Sullivan, there are many women involved in the forefront of marine research, development, innovation, along with master mariners, harbourmasters, sailors like Olympic medallist Annalise Murphy and offshore yachtswoman Joan Mulloy. Yvonne Shields O’Connor, formerly of the Marine Institute, is chief executive of the Commissioners of Irish Lights, and Ireland’s first female master marine Capt Sinead Reen is in a senior role at the National Maritime College of Ireland.

And Irish people no longer have to leave to have an impact in that big blue field. Marine Institute chief executive Dr Paul Connolly has been at the helm of the prestigious International Council for the Exploration of the Seas (ICES), and his predecessor, Dr Heffernan, is one of 15 experts on the European Commission’s Mission Board for Healthy Oceans, Seas, Coastal and Inland Waters. And the unthinkable happened in 2015 when a former Naval Service flag officer, now Vice-Admiral Mark Mellett, became head of the Defence Forces.

A global pandemic can focus attention on the potential of the ocean environment and the rich waters around this island - as a vital source of protein, new medical treatments and a source of renewable energy. However, a pandemic might also distract attention from its fragility, and the fact that man-made rubbish has reached the remote Mariana Trench and microplastics are poisoning the deepest ocean creatures.

“We have taken for granted the fact that we have been fortunate to live in the Goldilocks zone – that sweet spot in relation to the Sun,” Dr Sullivan told me in a recent interview.

Ireland is in the sweetest “Goldilocks zone” when it comes to marine resources. We must be ready to manage that good fortune sensitively, and for both communities and individuals, when the gold rush comes.

For boat passage through the locks east of Lock 12 into / out of Dublin on either the Royal or Grand Canals, Masters are requested to contact the Waterways Ireland Eastern Regional Office (M-F 9.30am-4.30pm) on tel: +353(0)1 868 0148 or email [email protected] prior to making passage in order to plan the necessary lock-keeping assistance arrangements.

On the Grand Canal a minimum of two days notice prior to the planned passage should be given, masters should note that with the exception of pre-arranged events, a maximum of 2 boats per day will be taken through the locks, travelling either east or west.

Movements in or out of the city will be organised by prior arrangement to take place as a single movement in one day. Boaters will be facilitated to travel the system if their passage is considered to be safe by Waterways Ireland and they have the valid permit(s) for mooring and passage.

Newcomen Lifting Bridge

On the Royal Canal two weeks’ notice of bridge passage (Newcomen Lifting Bridge) is required for the pre-set lift date, and lock assistance will then also be arranged. A minimum of 2 boats is required for a bridge lift to go ahead.

Waterways Ireland Eastern Regional Office (Tel: +353(0)1 868 0148 or [email protected] ) is the point of contact for the bridge lift.

A maximum number of boats passing will be implemented to keep to the times given above for the planned lifts (16 for the Sat / Sun lifts & 8 for the weekday lifts). Priority will be given on a first come first served basis.

On day of lift, boaters and passengers must follow guidance from Waterways Ireland staff about sequence of passage under bridge & through Lock 1, and must remain within signed and designated areas.

Events Held on the Waterways

All organised events taking place on the waterways must have the prior approval of Waterways Ireland. This is a twelve week process and application forms must be accompanied with the appropriate insurance, signed indemnity and risk assessment. The application should be completed on the Waterways Ireland events page at :

https://www.waterwaysireland.org/online-services/event-approval

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.
