Tributes have been paid to Col Michael Moriarty, one of the pioneers of scuba diving in Ireland, who died earlier this month.

As The Sunday Independent reports, wetsuits were unheard of when he took up diving, and he once described how “we would just launch ourselves from the shore or rocks, wearing big lumpy woollen clothing, to give us the illusion of being warmer”.

Described by friends and colleagues as “big-hearted”, generous and full of both integrity and energy, the Army officer served on a number of UN peacekeeping missions until his retirement at the rank of colonel in 1992.

Born in Bandon, Co Cork, on December 21, 1931, Moriarty spent part of his childhood in Listowel, Co Kerry, where he was drawn to the sea from an early age.

He recalled his diving career in his first book, Submerged: a Lifetime of Diving, published by Comhairle Fo-Thuinn (CFT), the Irish Underwater Council, in 2001.

Close friend Ronnie Hurley, recalls how Moriarty introduced him to diving "in a lovely rocky cove" off Spanish Point in Co Clare.

Moriarty gave Hurley a loan of his latex drysuit and showed him how to use twin corrugated-rubber breathing hoses – for this was before development of the non-return valve.

In Submerged, Moriarty charted the revolution in the sport after a French gas company engineer, Émile Gagnan, was asked by the French underwater explorer and navy captain Jacques Cousteau if he could develop a better breathing device. Cousteau then refined the open circuit valve or diving regulator developed by Gagnan.

Moriarty described how The Silent World, which Cousteau co-wrote with Frederic Dumas, became his “Bible”. Spear fishing was popular at the time, and Moriarty and colleagues represented Ireland in several international competitions. After CFT was founded in the Curragh in 1963, Moriarty became honorary secretary from 1964 to 1972 and president in 1973.

Fellow CFT committee member and former Army officer Shane Gray, who was also taught to dive by Moriarty, recalled that he was a “man of integrity, a big hearted, generous man, honourable, honest and full of energy for his work and for his hobbies, chiefly photography and diving”.

Garda Commissioner Drew Harris has been asked to recognise the bravery of two gardai who played a key role in a harrowing cave rescue in north Mayo 25 years ago.

Retired chief superintendent Tony McNamara made the appeal at an event at Lacken pier in north Mayo at the weekend to mark the 25th anniversary of the death of diver Michael Heffernan.

Heffernan, a member of Mayo’s Grainne Uaile Sub Aqua Club, lost his life while trying to rescue three members of a family who were trapped in the back of a sea cave near Belderrig on October 25th, 1997.

German national Will Ernst von Below also died when his new currach capsized in a sea cave at Horse Island, throwing his friends, Tony and Carmel Murphy and their young daughter Eimear into the sea.

Up to 100 people, including Commissioner Harris, Heffernan’s widow Ann Marie and daughter Michelle, members of the Murphy family and Irish Coast Guard director Eugene Clonan attended the event, which was hosted by a Grainne Uaile Sub Aqua Club team, including diver and councillor Michael Loftus.

Five wreaths were laid, with one of the wreaths also remembering the Lacken drownings of 1927 in a storm which also claimed lives off Cleggan and the Inishkea islands.

Three Scott medals for bravery were awarded to Garda members Ciarán Doyle, David Mulhall and Sean O’Connor for their role in the Belderrig cave rescue, which was one of the longest in recent Coast Guard history and involved about 100 people attached to 21 different services.

National marine bravery awards were also given to the gardai, and to Grainne Uaile diver Josie Barrett, Killala Coast Guard members Séan McHale and Martin Kavanagh and fishermen Martin and Patrick O’ Donnell.

Garda divers Kieran Flynn and Joseph Mulligan were commended for their role, but were passed over for Scott medals at the time.

McNamara said he had recommended that all five Garda divers should receive Scott medals for their efforts, and it was still one of his regrets that the bravery of both men was “overlooked”.

Addressing Commissioner Harris, who travelled to the event in north Mayo at the weekend, McNamara asked him “respectfully” if he might “have someone look at it again”.

“It’s never too late to undo a wrong,” McNamara said.

McNamara recalled how he had just arrived in Achill for the weekend when he got a phone call from the Garda station that four people had failed to return to Belderrig harbour from a boat trip, and a search was underway.

He recalled how Grainne Uaile club members Michael Heffernan and Josie Barrett attempted a dive, on a safety line, into the cave where the Murphys were trapped, assisted by their club colleagues and members of the Killala Coast Guard unit. Both divers were separated in violent sea conditions, and Barrett managed to make it back out.

The Irish Coast Guard helicopter from Shannon was asked to fly to Dublin to collect the five Garda divers, and efforts were made to identify and illuminate a landing area near the pier at Belderrig.

McNamara recalled how helicopter pilot Capt Dave Courtney wrote about the incident in his book, Nine Lives, describing how the aircraft was “greeted by an amazing sight…the landing site was illuminated by huge standing floodlights positioned at each corner of a large field”.

“We could see firemen with extinguishers, ambulances, Coast Guard members and Gardai. And in the shadows beyond, we could see the others, the locals, the community, unknown people just trying to help,” Courtney wrote.

Three of the Garda team, Sean O’Connell, Dave Mulhall and Ciaran Doyle, attempted to enter the cave underwater with the assistance of Sean McHale and Martin Kavanagh on the Killala Coast Guard rib but were beaten back by swell and currents. The boat was swamped, and its engine was smashed on the rocks, meaning.

“Fortunately, all five men made it safely to the back of the cave where they discovered that the three members of the Murphy family had somehow survived their ordeal; they also, tragically, found that Michael Heffernan and another man, Will Van Below had not survived,” McNamara said.

He recalled the key role played by Garda Ciaran Doyle, who volunteered to swim from the back of the cave with a rope which would then tow seven people on board the Coast Guard rib to safety.

Mayo fishermen Pat, Martin and Tony O’Donnell and the RNLI Ballyglass lifeboat assisted with radio communications, and Pat O’Donnell took Ciaran Doyle on board when he emerged, exhausted, at the cave mouth.

“Taking the tow rope on his bow and to keep his propeller clear of the rocks, Pat O’Donnell proceeded astern, a most difficult manoeuvre, to steer a boat in a straight line going astern, to keep off the rocks close by,” McNamara said.

“He was assisted in this by his brother, Martin, establishing a tow line to his boat and going ahead to keep the main towline to the Coast Guard rib as straight as possible, as it was successfully pulled from the cave,”he said.#

Garda divers Kieran Flynn and Joe Finnegan were taken into the cave by fisheries inspector Michael Hughes to recover the bodies of Michael Heffernan and Will Von Below, McNamara said.

McNamara noted that the State subsequently named the highest marine gallantry awards after Michael Heffernan, and the diver, whose wife was expecting their second child when he died, was posthumously awarded the first gold medal.

After a long break due to COVID, recreational diving is back on Dublin Bay and divers were out over the past two weekends at Dalkey Island and other popular bay sites.

A class of open water students got back into the water after a long break for a snorkel.

Local boat bives are also now fully operational in Dublin Bay again with regular departures to favourite dive sites around Scotmans Bay, Dalkey Island and the Muglins Beacon.

Mullingar's Dave McGowan, known for his recent achievements in the sport of freediving, takes his place on the podium once more. Last week, at the Aida International Blue Ocean Freedivers Pool Competition in Dahab, Egypt, McGowan took the Male Honours in both disciplines that he participated in and also took the overall gold.

Day one of the competition did not necessarily go to plan, with a malfunctioning dive computer contributing to McGowan overshooting his target, coming very close to losing consciousness on the surface and ultimately receiving a red card and disqualifying his dive of 162m, which took approximately 2minutes and 45 seconds. McGowan was quoted saying, "This dive of 162m was huge for me, I had built up to a distance of 135m in training and was confident that I could do 10-15m more on the day of the competition but certainly not almost 30m extra. I had been relying on the computer to give me a good idea of when I could surface and when it didn't work it had me questioning the distance that I had already covered, trying to work this kind of thing out at the end of such a long swim on one breath is not an easy thing. The mind becomes foggy and basic tasks rely on an element of the subconscious to get you through it. I essentially got it wrong and ended up swimming almost another complete length of the pool. I was surprised to be told that I had covered 160m+ when in my head I had barely made 135m." Unfortunately, at the end of the dive, McGowan was not able to complete the 'Surface Protocol', which signals to the judges that he is ok and was subsequently shown a red card.

McGowan returned on Day 2 determined to set the record straight. He completed his dive of 150m (equivalent to 6 lengths of a standard 25m pool) in the DYNb discipline (distance swam in pool on one breath using freediving fins) in a time of 2minutes and 35 seconds. This time he made a clean surface protocol, receiving a white card from the judges, legitimising his performance and confirming this dive as his 4th Irish National Record. "I wasn't really nervous leading into day one of this competition as I had approached my training in a conservative way and knew what I was capable of, however, arriving here on day 2 after what had happened on the first day I was feeling the nerves creep into the pit of my stomach. This sport is so psychological, it takes such mental strength, you really need to be able to control your thoughts and feelings and at times like these, in the moments before a record dive you have to be able to focus and get rid of any thoughts of negativity or doubts in your abilities. I feel like I handled it quite well and managed to complete what I had set as an upper limit for myself. I would have walked away satisfied with my performance and also with the record in anything above 132m, so to have been able to do 150m I really am over the moon – it was a difficult dive for me and for sure it will be difficult for anyone to beat in the future."

Day 3 saw McGowan return to finish off the competition with a 'fun' dive in the DNF or 'No-fins' discipline, (distance swam underwater on one breath in a style similar to the breast-stroke). In both depth and pool, this discipline is usually considered the most pure, and most original of all of the freediving disciplines, it is graceful to watch and more-so with the right training and technique, enjoyable to compete in. McGowan's swim of 116m in 2mins 19 secs places him 3rd of all time in the Irish rankings for this discipline.

“We’ll always give our best, treat every incident as if it is one of our own.... and try our utmost to get a missing family member back to their loved one.....”

The words of Lieut Stephen Stack, head of the Naval Service diving unit, speaking about what keeps his colleague “motivated and driven to succeed”.

Last year, Sub-Lieut Tahlia Britton from Rossnowlagh, Co Donegal, became the first female to qualify for the Naval Service diving unit. A former champion surfer, she studied podiatry at NUI Galway but always wanted to join the military.

She has described the mental and physical challenges of being a Navy diver in an interview recorded for RTÉ Seascapes, the full version of which is on a Wavelengths podcast this week (below).

Search and recovery is just one aspect of the work of Navy divers, which is, as Stack says “not glamorous...”

One of the team’s recent challenging operations was the three-week-long search after the 12-metre steel-hulled boat, Alize, fishing out of Duncannon, Co Wexford, went down some 6½ miles off Hook Head, Co Wexford just over a year ago on January 4th, 2020.

Joe Sinnott (65) from Kilmore Quay was recovered off Duncannon by the Irish Coast Guard Waterford-based Rescue 117 helicopter.

The body of skipper Willie Whelan (41), recently married and from Fethard-on-Sea, was located by the Hook Sub Aqua Club, and it was taken from the wreck of the new vessel by the Naval Service diving team.

“It was in very deep water, it was very complex, the weather wasn’t great, “Lieut Stack said, describing it as technically the most challenging operation he had been involved in recently.

He has paid tribute to the Garda Water Unit and the voluntary search and recovery groups that the Navy divers also work with in their aid to civil power role.

Norwegian divers have discovered a 300-year-old shipwreck of an Irish sailing ship on the sea bottom outside Mandal in Southern Norway.

The Irish ship, named "The Providentz", sunk in November 1720.

It is reported by the Norwegian NRK journalist, Siv Kristin Sællmann, that all crew members were saved, but the ship was left at the sea bottom. Divers and archaeologists are astonished by how well-preserved the ship and its possessions are.

The ship and most of the possessions will be left on the sea bottom for divers to explore freely.

Dublin Bay diver Rory Golden will join the 2021 Titanic Survey Expedition starting in May going back to the wreck after a gap of 16 years, and taking part in a “sea bed” breaking scientific expedition.

Golden has over 44 years of dive experience and played key roles in Titanic expeditions and dives in 2000 and 2005.

Citizen explorers, known as Mission Specialists, will work hand-in-hand with Golden and other scientific, archaeological, and oceanographic experts throughout the expedition.

“I will never forget the first time I saw the Titanic. We were travelling along the flat ocean floor towards the ship and we came upon a wall of mud,” recalls Rory Golden. “We were at the forward section, near the bow, and we slowly rose up a steel wall that was covered in rivets and rusticles. Eventually we ascended over the top and there she was. It was a rush of emotion. She is massive and awe-inspiring. You are excited, amazed, and, at the same time, you feel a deep sadness for all those lost. It is unlike anything else I have experienced in over 40 years of diving. In the five short years between my dives to the Titanic the changes were dramatic. I’m anxious to bear witness to the deep ocean’s impact on this historic sight,” says Golden.

Rory is highly regarded in the dive and Titanic communities. As a member of the Explorers Club and Vice Chair of the Great Britain and Ireland Chapter, he has been an active explorer, diver, and researcher dedicated to the preservation of Titanic history. We are proud and excited to welcome him to our expeditionary team for the 2021 Titanic Survey Expedition,” says Stockton Rush, President, OceanGate Expeditions. “His knowledge and previous documentation of this revered shipwreck will help us navigate the features of the wreck site and assess how quickly the wreck is decaying,” continues Rush.

Six missions scheduled for Summer 2021 will mark the inaugural expedition of a multi-year effort to preserve Titanic history for future generations and document the rate of decay of the important site. Using an array of high-resolution 4K cameras, a laser scanner, and sonar equipment, OceanGate Expeditions’ team will create a fully explorable photorealistic virtual 3-D model of the site.

Each participating citizen scientist will embark on 8-days at sea as a Mission Specialist crewmember and make one untethered 8 to 10-hour submersible dive as part of a 5-person team (sub pilot, subject matter expert, three mission specialists).

Each submersible dive team will spend several hours exploring the renowned Titanic wreck-site. The Summer 2021 Expedition schedule runs late-May through mid-July.

Irish deep-sea diver Rory Golden is providing expertise to a new expedition to the Titanic which aims to recover the Marconi radio from the wreck, The Sunday Times reports.

The wireless Marconi telegraph was instrumental in saving more than 705 passengers from freezing Atlantic waters when the ship sank after striking an iceberg off Newfoundland in April 1912 with the loss of almost 1500 lives.

As Afloat reported previously, the ambitious project to retrieve the most famous marine radio in the world from 2.5 miles down in the Atlantic has finally secured legal approval.

The new expedition planned by RMS Titanic Inc, the salvor-in-possession, will be led by Dr David Gallo and French former naval officer Paul Henri Nargeolet.

Dublin-based Golden, who was the first Irish diver to visit the wreck site in almost 4,000 metres of water, has been engaged as a consultant to the company which has recovered over 5,500 artefacts in eight previous expeditions.

The former managing director of Virgin Records Ireland was dive safety operations manager for the Operation Titanic 2000 project which recovered 800 items - including the main ship’s wheel which he spotted. He returned in 2005 for a second dive, which was recorded in a BBC documentary.

In March 2013 he was a member of the team sponsored by Amazon.com founder Jeff Bezos which salvaged five Apollo F-1 rocket engines from 4200 metres in the North Atlantic, including one from Apollo 11 which launched a man to the moon in 1969.

Golden’s participation is one of several Irish connections to the new diving expedition which is expected to cost at least 10 million US dollars.

A Mayo community’s support for the new venture also helped to secure recently approved US Admiralty Court permission for it.

A letter to the US Admiralty Court from Addergoole Titanic Society director Toss Gibbons, secretary Mary Rowland and public relations officer Frank Gibbons urged that it would “give its blessing” to RMS Titanic Inc to undertake the expedition. The society remembers 11 of the ship’s fatalities from the Mayo village of Laherdane and surrounding area.

“We spent a lot of time in Ireland, in Belfast and with the folks in Addergoole to put a plan together which would satisfy the court,” RMS Titanic Inc president Bretton Hunchak said.

The recovery of the Marconi telegraph is crucial to understanding “the story of all of the survivors”, Hunchak explained.

“Ultimately, the Marconi radio system remains an unsung hero, responsible for countless generations of families that exist only because the radio cried out on behalf of their ancestors,” he said.

“ For that reason, we must recover this incredible piece of history, to rescue the radio that saved 705 lives from being taken from the world that fateful night."

Hunchak said the original plan for the expedition was within a weather window between June and August of this year, and that might still take place.

“Obviously, with the Covid-19 pandemic, we have questions now and will make a decision on timing very shortly,” he said.

“The Marconi telegraph is recognisable, from our underwater photography, but if we recover it there will be considerable conservation required before we can take it around the world as part of our exhibition of artefacts,” he said.

Golden said the project was “fraught with a lot of unknown and known variables, such as the condition of the roof area, the wreck itself, currents, visibility” and other factors, but has “a very good chance of succeeding”.

The wreck of the Titanic was discovered by Dr Robert Ballard and Jean Louis Michel in a joint US/ French expedition on September 1st, 1985, some 963 miles northeast of New York and 453 miles southeast of the Newfoundland coastline.

Divers of the Naval Service which form an elite unit in the force is operating at less than a quarter of its intended capacity as a result of the Defence Force’s retention crisis.

Naval Service Diving Section according to The Irish Times, is the only dive team in Ireland capable of carrying out deep sea operations. It has a wide variety of roles but its most prominent function is carrying out search and recovery operations for missing persons.

It carries out an average of 15 missing person searches every year, some of which last for up to two weeks at a time.

The diving section has an establishment strength of 27 divers but is operating with just six as a result of highly trained personnel leaving for the private sector. Moreover, the problem is compounded by a lack of replacements coming through.

The diving section has not been at full strength since before the reorganisation of the Defence Forces in 2012 which was marked by significant cuts to resources and a new manpower limit of 9,500.

Last Sunday, Wexford Sub Aqua Club, presented the Kilmore Quay branch of the RNLI, with a cheque for €1,000. The presentation was done just before the crew went out for their scheduled morning training exercise.

This money was raised by members and friends of the club at their annual Christmas Swim.

This year’s swim was noticeable due to the temperature of the water, which swimmers commented on as being the coldest since the club started to do the event.

Swim organiser, Ivan Donoghue said that “it was so cold, that while swimmers walked to the waters edge, the sand was cracking under their feet. We braved the water for a few minutes, but the members of all the RNLI face such conditions on every call they go on. We thank everyone who took part, those who sponsored the swimmers and the Kilmore Quay RNLI for being there to protect the people who use the waters around the Saltee Islands” 

The club’s next event is on Sunday April 22nd at 10.30am. It is a 5 mile fun run/walk around the scenic Kilmore Quay village and registration is at our clubhouse overlooking the Saltee islands. €10 entry for adults.

The club are currently in the process of teaching our five new members how to dive.

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.”
