An hourly train service should be operating between major cities and at least one train every two hours between other urban centres, according to a new report that recommends the transformation of the current rail system including port rail freight.

At a launch (yesterday, 25 July), Minister for Transport Eamon Ryan will bring the draft report of the first All-Island Strategic Rail Review (AISRR). The review makes for 30 recommendations that will be brought to the Cabinet.

The AISRR wants to have faster speeds amd improved frequency in addition to new rail routes for people and those for freight. The latter is particularly aimed to be in place across the west and north regions of the country.

Recommendations in the report would take a timeframe beyond 25 years to achieve, however several of the proposals could be implemented beforehand by 2030.

Among the recommended proposals include reducing the level of trucks off the roads with the Limerick to Foynes Port railway reinstated for freight as Afloat previously reported and potentially for passengers returning on the Shannon estuary rail link.

In addition another rail-freight project is to start reopening the south Wexford railway line connecting Waterford and Rosslare Europort, operated by Irish Rail (Iarnród Éireann).

In addition there is a suggestion to develop a rail line around Dublin Port

For more on the AISRR recommendations including Northern Ireland, RTE News reports as well to coverage of matters maritime, as the Minister also highlighted issues facing lighthouse authorities on both sides of the Irish Sea.

General Lighthouse Authorities  

The Minister is seeking Cabinet approval for an international agreement between the General Lighthouse Authorities (GLA) in Ireland and Britain.

Responsibility for the navigation safety around the coasts of Ireland and the UK is overseen by the three lighthouse authorities as Afloat has featured notably of recent years given plans to replace ageing aids to navigation vessels with newbuilds.

The GLA's are the Commissioners of Irish Lights for Ireland and Northern Ireland, the Northern Lighthouse Board for Scotland and the Isle of Man, and Trinity House for England, Wales, the Channel Islands and Gibraltar.

All three GLA's have used joint procurement measures to benefit from the economies of scale and by having closer operational ties. This process was straightforward when all the three lighthouse authorities were under the same EU procurement regime.

However, given post-Brexit this has led to a new solution being required.

The Minister has been advised by the Attorney Gerneral that an international agreement be implemented so to enable the GLA's to achieve solutions.

Among them is the key contract to provide helicopter services needed to service lighthouses in offshore remote locations in particular on Ireland's western seaboard.

Great Lighthouses of Ireland (series two, programme three) continues this Sunday, May 22nd 2022 on RTÉ One TV at 6.30 pm

Lighthouse technology is constantly evolving, ensuring that lights are as bright as possible for the safety of the mariner at sea. This third episode explores the fascinating history of lighthouse optic engineering and ingenuity, from the basic oil burners and reflectors of the 1700s to the invention of the Fresnel lens which dramatically enhanced the power of the light; improvements to the light sources, and how lighthouses got their characteristic flashes. 

A short distance from Cromwell Point lighthouse, Valentia Island, Co Kerry, is the landing place for the first transatlantic cable: the most advanced communications technology in the world in the mid 19th century.

Mícheál Lyne, Kerry HistorianMícheál Lyne, Kerry Historian

Spanning 2,500 miles from Newfoundland to Valentia, across an ocean which is 2 miles deep in places, the successful laying of the cable has been described as the equivalent of the moon landings for the people of that era.

After two attempts, the third proved to be successful and in 1866 the entire cable was carried and laid by one ship, ‘The Great Eastern’, whose first officer was Robert Halpin from Wicklow Town, Co. Wicklow. The Valentia cable station had a huge economic and social impact on the island, and the last telegraphic message was sent in 1966 as radio wave technology took over.

Ireland’s lighthouses also played a part in the development of radio wave and wireless technology. Radio wave pioneer Guglielmo Marconi was born in 1874 to an Irish mother and an Italian father. Marconi was able to achieve what had previously been regarded as impossible, and prove that electrical waves could cross the Atlantic wirelessly and without the need for cables. By 1904, radio signalling technology had been installed on the Fastnet lighthouse meaning the keepers could be contacted quickly from the shore, and could also send danger signals and messages about the light. A new chapter in technology began as radio waves were used to save lives at sea.

Perhaps the most challenging job of all within the lighthouse service was that of a lightshipman.

Even tougher than living on a remote lighthouse station, lightships were anchored into place and truly at the mercy of the sea. For almost 250 years lightship men were stationed around the Irish coast, displaying incredible bravery, integrity and strength of mind. Former lightship men describe conditions on a lightship, including the psychological challenges, food shortages, overdue reliefs and the constant threat of being struck by another vessel.

The loss of the Puffin lightship near the Daunt Rock in 1896 illustrates just how dangerous it was to be a lightshipman. Despite being the height of technology, the Puffin was destroyed in a violent storm with the loss of all 8 crew who were never found. Using 19th-century diving technology, the wreck of the Puffin was found against all odds and brought to shore. Ireland’s lightships were gradually replaced by automatic buoys, and the last lightship ‘The Gannet’ was decommissioned in 2009 and removed from the Co. Down coast.

The hugely popular* Great Lighthouses of Ireland is back for a second series with more stories about the lighthouses around Ireland’s coast and the extraordinary men and women who lived and worked in them, including the lightship keepers whose working conditions were even tougher than those on the remotest of Ireland’s rock stations.

The series covers a wide range of topics designed to appeal, as the first series did, to all ages. Shipwrecks, the power of waves, the disastrous 1979 Fastnet Race, lighthouses in art, storms, engineers, lightships, Marconi, Admiral Beaufort, bird surveys, the Dingle lighthouse keeper who first spotted Fungie the dolphin, the importance of food and the tactics employed by lighthouse keepers to get on with the men they shared a very small space with, are just some of the topics explored.

Programme two on May 15th 2022 - RTÉ One, 6.30 pm

Ireland’s coastline is notoriously rugged and treacherous, and over 18,000 shipwrecks have been recorded in Irish waters. Many of these wrecks occurred during the 19th century when ships became larger and faster: the sinking of the Queen Victoria on the rocks below the Baily Lighthouse, Co. Dublin is an infamous example.

Admiral Francis Beaufort, originally from Navan, Co Meath, dedicated his life to making vital improvements to navigational charts mapping. As Chief Hydrographer to the Royal Navy, he created maritime maps and charts that were still in use until the 1970s.

Ireland’s marine territory is roughly ten times the area of the island of Ireland, making Ireland one of the largest territorial countries in Europe. This dramatic increase of territory was made official by the United Nations Convention on the Law of the Sea, and how it is illustrated in the ‘Real Map of Ireland’.

Over on the east coast, the seabed, largely comprising sand and mud, is constantly changing. This is very evident at the notorious Kish Bank off the coast of Dublin, a shallow and dangerous sandbank. Since 1810, a series of lightships, and eventually a lighthouse, have helped mariners passing Kish Bank (the lighthouse itself is an astounding feat of 20th century engineering).

Storms are one of the most lethal threats to mariners around the Irish coast. Admiral Beaufort devised the universally recognised method to describe wind strength, the Beaufort Wind Scale. Deadly Atlantic storms can erupt in a matter of hours.

In 2017 Storm Ophelia seriously damaged the lighthouse keepers’ cottages at Old Head Kinsale.

Although the lighthouse and cottages are perched 30 metres above sea level, waves smashed through windows destroying bedrooms, the sitting room and most of the downstairs, as we see in home videos made by Attendant Alan Boyer's wife Cathy Lennon. Despite being an experienced lighthouse keeper and attendant, Alan admits to being frightened as he and his family huddled at the top of the stairs.

Since the 19th century, Irish Lights has owned and run its own ships. The latest in a historic line of Irish Lights vessels is the Granuaile which plays a vital role in deploying and recovering buoys, hydrographic surveys, seabed sampling and mapping, search and rescue operations and helicopter support. Past and present crew members offer insights into life onboard Irish Lights’ ships which have served anyone who has sailed around the Irish coast for the past 200 years.

A lighthouse in Denmark that was first lit in 1900 has been moved further inland on special rails to protect it from coastal erosion.

TheJournal.ie reports on the 23-metre-tall Rubjerg Knude, which was deactivated in 1968 yet remains a popular landmark in the far north of Denmark.

However, the area is subject to shifting sands and coastal erosion that saw the lighthouse museum and coffee shop abandoned in 2002, and even led to the dismantling of 750-year old church close by in 2008.

Originally 200 metres from the shore, the lighthouse was just six metres from the edge when works began last week to move it some 70 metres inland on a set of specially built rails to accommodate its heavy masonry.

It’s now hoped that the future of the lighthouse, described by Danish environment minister Lea Wermelin as “a national treasure”, has been assured until 2060.

The new light on Fastnet Rock Lighthouse is scheduled to go into operation on schedule on the evening of Monday 2nd July, the Commissioners of Irish Lights has confirmed.

The new rotating lantern will have the same character as the existing light and a range of 18 nautical miles. The lighthouse will continue to provide an essential safety service for mariners as well as being visible along the Cork shoreline from Mizen Head to Castletownshend.

The switch to the new light will facilitate commencement of essential structural works which are required to renew the attachment of the lantern room to the masonry structure of the tower. Work will continue on Fastnet until late August 2018 and final completion works will take place in summer 2019. On completion, the outward appearance of Fastnet will be unchanged.

Irish Lights Director of Operations, Captain Robert McCabe, said: “The present works at Fastnet are part of the continuing investment programme of maintenance, upkeep and modernisation of the aids to navigation services provided by Irish Lights to the mariner. The project being undertaken at Fastnet involves important structural works to secure the station for the future, and the installation of a new light on a replacement platform above the dome. The works will improve safety and the environmental footprint at the station while having no impact on the outward appearance of the lighthouse.”

The public consultation process undertaken with the project has led to increased consideration of the international importance of Fastnet as a unique example of lighthouse heritage and the potential for the site to achieve UNESCO World Heritage List status.

Irish Lights responded to this interest and commissioned an independent expert report which concludes that the present works on Fastnet do not negatively impact on its potential for world heritage status. The report also found that the consideration of Fastnet for UNESCO status would best be progressed jointly with other countries operating similar towers.

Yvonne Shields Irish lights Irish Lights CEO, Yvonne Shields

Irish Lights CEO, Yvonne Shields, said: “Our discussions with the local community and interested parties raised the question of Fastnet qualifying for UNESCO World Heritage Status. In response, we commissioned a report from an international expert to explore the potential for Fastnet to be considered a world heritage site and to get a better understanding of the context within which this might be considered.

“The consultant confirmed the criteria under which he felt the Fastnet might qualify for UNESCO status and confirmed that the work underway at the site will not impact negatively on this ambition. The report notes that the World Heritage Committee specifically recognises the importance of continual renewal of internationally important industrial world heritage sites in the context of their sustained use as viable working entities. 

“Irish Lights will work with stakeholders and the community to determine the best way to advance the important heritage value of Fastnet as an international landmark.”

The Great Lighthouses of Ireland Partnership, the all-island tourism initiative developed by the Commissioners of Irish Lights, has announced Insomnia Chairman, Entrepreneur and TV and radio personality Bobby Kerr as the new Independent Chairperson to support the project’s development. A keen yachtsman with a passion for all things maritime, Bobby will chair the body which features twelve lighthouses in breath-taking coastal locations from Donegal to Cork and from Antrim to Wexford.

In his first act as Chairperson, Bobby attended Seafest 2017 national maritime festival in Galway where he met with GLI Partners, lighthouse operators, and representatives from the Commissioner of Irish Lights.

Bobby takes up the pro-bono role at an exciting time for Great Lighthouses of Ireland, with the Partnership having recently agreed a new marketing and development strategy up to 2020 with the aim of driving up visitor numbers and growing revenue. The GLI Partnership will benefit from Bobby’s business expertise and understanding of community projects to help in building the profile of the lighthouse properties.

With tourists offered the chance to both visit and stay in a lighthouse, the twelve GLI sites combined attracted some 135,000 visitors in 2016. There are over 19,000 bednights available across the various lighthouses; GLI Partnership is forecasting a 9% growth in visitor numbers and over 60% visitor occupancy in bednights in 2017. Both funding and resources have been committed to position the 12 lighthouses as must see, unique and high quality experiences for domestic and international visitors.

Welcoming Bobby Kerr’s appointment, Chief Executive of Irish Lights, Yvonne Shields commented: “Our maritime heritage is a great source of pride. Through Great Lighthouses of Ireland, Irish Lights has brought together a group of people who are deeply rooted in our coastal communities and hugely committed to our lighthouse heritage, and we are delighted that Bobby Kerr will be working with us to support this leading-edge project.”

“Given the success of this initiative to date, Bobby’s background and experience will be of huge value in guiding and informing the future work plans and objectives of the partnership and we look forward to developing exciting new collaborative initiatives with our lighthouse partners over the next phase of development of the project.”

Speaking as he accepted the invitation to act as Chairperson, Bobby Kerr said: “I’m incredibly excited to be given this unique opportunity to contribute to such a high-profile and imaginative tourism offering as the Great Lighthouses of Ireland.

I am committed to ensuring that this partnership adds value to the national tourism development agenda, partners and coastal communities in a manner that is sustainable and one that we are all proud to be associated with.”

#MewIslandOptic - Plans to install a rare lens from one of Ireland’s tallest lighthouses on Belfast’s waterfront have been given the green light.

As previously reported on Afloat.ie, plans were announced last summer to house the optic from Mew Island Lighthouse in Belfast Lough in a much more accessible structure designed by architects Hall McKnight.

Now the News Letter reports that planning permission has been granted to install the 130-year-old, seven-metre-tall optic in the Titanic Quarter as the centrepiece of the new Titanic Walkway in the coming months.

“We are now one step closer to helping save and restore one of the largest optics of its kind ever constructed, an artefact of national and international significance,” said Titanic Foundation chief executive Kerrie Sweeney.

“This will certainly create a legacy Belfast landmark which will inspire our future generations.”

#Exhibition - The Commissioners of Irish Lights and the Royal Irish Academy continues to tour an exhibition around our coastline that captures the history of Irish Lights.

Having first exhibited last year in Cobh as Afloat reported on the next venue will be Wexford at the town’s County Office HQ and is scheduled from 23 January-5 March. The location is at Carricklawn (close to Wexford General Hospital) on the (R769) road that leads west out of the town.

The history of the island of Ireland itself, its ever-changing coasts and shorelines, and the history of the people who lived along our island’s seaboard. Through the nineteenth century the number of Ireland’s lighthouses increased from fourteen to seventy-four, with eleven lightships placed around the east and south coasts.

The exhibition explores how Irish Lights, with its origins in the late-eighteenth century, and coming of age in the certainties of the nineteenth, faced the challenges of global and national uncertainty in the early twentieth century. Precisely, the exhibition details Irish Lights’ history between 1911 and 1923.

Also explored in the exhibition through these years are the incredible events, such as; the Easter Rising of 1916, the Anglo-Irish War of 1919–1921 and the Anglo-Irish Treaty.

What emerges is a never-before told story of devotion to duty, scientific, engineering and physical endeavour, world war, revolution and change.

It is also a deeply personal story of those who worked with and built up Irish Lights. Those who devoted their lives to protecting the coastline for the safety of all which remains to the present day and by keeping abreast of future technological developments.

For all you need on the Marine Environment - covering the latest news and updates on marine science and wildlife, weather and climate, power from the sea and Ireland's coastal regions and communities - the place to be is Afloat.ie.

Coastal Notes

The Coastal Notes category covers a broad range of stories, events and developments that have an impact on Ireland's coastal regions and communities, whose lives and livelihoods are directly linked with the sea and Ireland's coastal waters.

Topics covered in Coastal Notes can be as varied as the rare finding of sea-life creatures, an historic shipwreck with secrets to tell, or even a trawler's net caught hauling much more than just fish.

Other angles focusing the attention of Coastal Notes are Ireland's maritime museums, which are of national importance to maintaining access and knowledge of our nautical heritage, and those who harvest the sea using small boats based in harbours where infrastructure and safety pose an issue, plying their trade along the rugged wild western seaboard.

Coastal Notes tells the stories that are arguably as varied as the environment they come from, and which shape people's interaction with the natural world and our relationship with the sea.

Marine Wildlife

One of the greatest memories of any day spent boating around the Irish coast is an encounter with Marine Wildlife. It's a thrill for young and old to witness seabirds, seals, dolphins and whales right there in their own habitat. And as boaters fortunate enough to have experienced it will testify, even spotting a distant dorsal fin can be the highlight of any day afloat. Was that a porpoise? Was it a whale? No matter how brief the glimpse, it's a privilege to share the seas with Irish marine wildlife.

Thanks to our location in the North Atlantic, there appears to be no shortage of marine life to observe. From whales to dolphins, seals, sharks and other ocean animals, the Marine Wildlife category documents the most interesting accounts around our shores. And we're keen to receive your observations, your photos, links and video clips, too!

Also valuable is the unique perspective of all those who go afloat, from coastal sailing to sea angling to inshore kayaking to offshore yacht racing, as what they encounter can be of great importance to organisations such as the Irish Whale and Dolphin Group (IWDG). Thanks to their work we now know we share the seas with dozens of species who also call Ireland home. But as impressive as the list is, the experts believe there are still gaps in our knowledge. Next time you are out on the ocean waves, keep a sharp look out!

Weather

As an island in the North Atlantic, Ireland's fate is decided by Weather more so than many other European countries. When storm-force winds race across the Irish Sea, ferry and shipping services are cut off, disrupting our economy. When swollen waves crash on our shores, communities are flooded and fishermen brace for impact - both to their vessels and to their livelihoods.

Keeping abreast of the weather, therefore, is as important to leisure cruisers and fishing crews alike - for whom a small craft warning can mean the difference between life and death - as it is to the communities lining the coast, where timely weather alerts can help protect homes and lives.

Weather affects us all, and Afloat.ie will keep you informed on the hows and the whys.

Marine Science

Perhaps it's the work of the Irish research vessels RV Celtic Explorer and RV Celtic Voyager out in the Atlantic Ocean that best highlights the essential nature of Marine Science for the future growth of Ireland's emerging 'blue economy'.

From marine research to development and sustainable management, Ireland is developing a strong and well-deserved reputation as an emerging centre of excellence. Whether it's Wavebob ocean energy technology to aquaculture to weather buoys and oil exploration, the Marine Science category documents the work of Irish marine scientists and researchers and how they have secured prominent roles in many European and international marine science bodies.

Power From The Sea

The message from the experts is clear: offshore wind and wave energy is the future. And as Ireland looks towards the potential of the renewable energy sector, generating Power From The Sea will become a greater priority in the State's 'blue growth' strategy.

Developments and activities in existing and planned projects in the pipeline from the wind and wave renewables sector, and those of the energy exploration industry, point to the future of energy requirements for the whole world, not just in Ireland. And that's not to mention the supplementary industries that sea power projects can support in coastal communities.

Irish ports are already in a good position to capitalise on investments in offshore renewable energy services. And Power From The Sea can even be good for marine wildlife if done properly.

Aside from the green sector, our coastal waters also hold a wealth of oil and gas resources that numerous prospectors are hoping to exploit, even if people in coastal and island areas are as yet unsure of the potential benefits or pitfalls for their communities.

Changing Ocean Climate

Our ocean and climate are inextricably linked - the ocean plays a crucial role in the global climate system in a number of ways. These include absorbing excess heat from the atmosphere and absorbing 30 per cent of the carbon dioxide added to the atmosphere by human activity. But our marine ecosystems are coming under increasing pressure due to climate change.

The Marine Institute, with its national and international partners, works to observe and understand how our ocean is changing and analyses, models and projects the impacts of our changing oceans. Advice and forecasting projections of our changing oceans and climate are essential to create effective policies and management decisions to safeguard our ocean.

Dr Paul Connolly, CEO of the Marine Institute, said, “Our ocean is fundamental to life on earth and affects so many facets of our everyday activities. One of the greatest challenges we face as a society is that of our changing climate. The strong international collaborations that the Marine Institute has built up over decades facilitates a shared focusing on our changing ocean climate and developing new and enhanced ways of monitoring it and tracking changes over time.

“Our knowledge and services help us to observe these patterns of change and identify the steps to safeguard our marine ecosystems for future generations.”

The Marine Institute’s annual ocean climate research survey, which has been running since 2004, facilitates long term monitoring of the deep water environment to the west of Ireland. This repeat survey, which takes place on board RV Celtic Explorer, enables scientists to establish baseline oceanic conditions in Irish waters that can be used as a benchmark for future changes.

Scientists collect data on temperature, salinity, water currents, oxygen and carbon dioxide in the Atlantic Ocean. This high quality oceanographic data contributes to the Atlantic Ocean Observing System. Physical oceanographic data from the survey is submitted to the International Council for the Exploration of the Seas (ICES) and, in addition, the survey contributes to national research such as the VOCAB ocean acidification and biogeochemistry project, the ‘Clean Atlantic’ project on marine litter and the A4 marine climate change project.

Dr Caroline Cusack, who co-ordinates scientific activities on board the RV Celtic Explorer for the annual survey, said, “The generation of long-term series to monitor ocean climate is vital to allow us understand the likely impact of future changes in ocean climate on ecosystems and other marine resources.”

Other activities during the survey in 2019 included the deployment of oceanographic gliders, two Argo floats (Ireland’s contribution to EuroArgo) and four surface drifters (Interreg Atlantic Area Clean Atlantic project). The new Argo floats have the capacity to measure dissolved ocean and biogeochemical parameters from the ocean surface down to a depth of 2,000 metres continuously for up to four years, providing important information as to the health of our oceans.

During the 2019 survey, the RV Celtic Explorer retrieved a string of oceanographic sensors from the deep ocean at an adjacent subsurface moored station and deployed a replacement M6 weather buoy, as part of the Irish Marine Data Buoy Observation Network (IMDBON).

Funded by the Department of Agriculture, Food and the Marine, the IMDBON is managed by the Marine Institute in collaboration with Met Éireann and is designed to improve weather forecasts and safety at sea around Ireland. The data buoys have instruments which collect weather and ocean data including wind speed and direction, pressure, air and sea surface temperature and wave statistics. This data provides vital information for weather forecasts, shipping bulletins, gale and swell warnings as well as data for general public information and research.

“It is only in the last 20 years, meteorologists and climatologists have really began to understood the pivotal role the ocean plays in determining our climate and weather,” said Evelyn Cusack, Head of Forecasting at Met Éireann. “The real-time information provided by the Irish data buoy network is particularly important for our mariners and rescue services. The M6 data buoy in the Atlantic provides vital information on swell waves generated by Atlantic storms. Even though the weather and winds may be calm around our shores, there could be some very high swells coming in from Atlantic storms.”
