Displaying items by tag: Bluefin Tuna

Applications have opened for experienced angling skippers to catch and release Atlantic bluefin tuna as part of a collaborative scientific survey.

The initiative targets Atlantic bluefin tuna — the world’s largest tuna species — to collect information on their sizes, and where and when they occur in Irish waters.

The programme saw recaptures for the first time in 2023 as well as changes in the size of the fish encountered, providing useful and positive data on this iconic and tightly managed species.

Recreational angling for Atlantic bluefin tuna is technically prohibited in Ireland.

Unauthorised vessels are not permitted to target or catch bluefin tuna and any unauthorised person found to be targeting bluefin tuna is liable to prosecution.

However, under the Tuna CHART (CatcH And Release Tagging) programme, authorised charter vessel skippers can catch, tag and release bluefin during the open season, with the help of anglers on board.

Skippers will be required to have high-specification rods, reels and lines to ensure that each bluefin tuna is brought alongside the vessel for tagging in a timely manner, prior to their subsequent release.

In previous years all tuna were carefully managed, subject to strict guidelines set by the Tuna CHART programme, and all were released alive. In 2023, the programme recorded:

  • Two recaptures of tagged Atlantic bluefin tuna for the first time
  • A total of 381 bluefin tagged
  • 239 bluefin tuna angling trips undertaken
  • 4.5 bluefin caught per trip in the most successful week

In 2024, a maximum of 25 authorisations may be granted to qualifying angling charter vessel skippers around the Irish coast. This fishery will open on 1 July and close on 12 November.

Experienced charter skippers can apply to join the 2024 Tuna CHART programme until this Wednesday 8 May by completing the online application form.

Inland Fisheries Ireland (IFI) has recorded two rare recaptures of tagged Atlantic bluefin tuna as the angling season for these fish nears its closure on Sunday 12 November.

The first recaptured bluefin was tagged and released originally by skipper Adrian Molloy on 2 October 2020 in Donegal Bay. Three years later, the same fish was caught again on 11 September this year off the north-east coast of Spain.

The second bluefin was originally tagged and released by skipper Tony Santry on 23 August this year off the Kerry coast and recaptured just 22 days later on 14 September off the west French coast. This Atlantic bluefin tuna had travelled a distance of 750km in three weeks, data showed.

Dr William Roche of IFI said: “Atlantic bluefin tuna are leviathans of the sea, and a bucket list species for many anglers.

“For the first time in the five years of this programme, two recaptures have been recorded — that’s two from over 1,600 fish tagged.

One of the first two Atlantic bluefin tuna caught of the 2023 Tuna CHART season, captured, tagged and released off the Irish coast in late JulyOne of the first two Atlantic bluefin tuna caught of the 2023 Tuna CHART season, captured, tagged and released off the Irish coast in late July

“To date, 1,619 bluefin tuna have been tagged by skippers along the north west, west and south coast of Ireland since the Tuna CHART programme, an inter-agency Government research initiative started in 2019.”

Recreational angling for Atlantic bluefin tuna is technically prohibited in Ireland. However, under the Tuna CHART programme, authorised charter skippers can catch, tag and release bluefin during the open season with the help of anglers as ‘citizen scientists’ on board.

This scientific tuna fishery targets the largest tuna species to collect information on their sizes, and where and when they occur in Irish waters.

The largest tuna tagged to date in the programme was 2.75m long, and weighed an estimated 372kg.

In 2022, 382 Atlantic bluefin tuna were caught, tagged, and released around the Irish coast by authorised skippers.

Skippers willingly provide their expertise to the programme and can charge anglers for bluefin tuna trips on their vessels.

Measuring, tagging and releasing bluefin tuna is carried out in the water alongside the boat, which progresses slowly at speeds of 2-3 knots, to ensure the fish remains in the best possible condition.

Bluefin are caught in area that extends from approximately 1km from the shore out to a maximum of about 20km.

Marine Minister Charlie McConalogue attended the Agriculture and Fisheries Council in Luxembourg on Monday (23 October) where there were a number of important fisheries items on the agenda.

Among those were an exchange of views on the EU priorities for the upcoming ICCAT (International Commission for the Conservation of Atlantic Tuna) meeting in Cairo.

Minister McConalogue welcomed the positive stock assessment for northern albacore tuna and the significant increase on the current total allowable catch.

He added that Ireland “calls to reopen a discussion within the EU on internal reallocation of the EU’s bluefin tuna quota in light of the new management plan and the recent adjustment to the ICCAT sharing arrangements”.

Another important aspect of the meeting were contributions from member states on the ongoing negotiations in respect of the Baltic Sea 2024 Fishing Opportunities Regulation.

The minister welcomed the progress that had been made by participating member states on the Baltic Sea 2024 Fishing Opportunities Regulation.

Minister McConalogue will attend the Joint Oireachtas Committee on Agriculture Food and the Marine later this Wednesday (25 October) to present the Sustainability Impact Assessment in relation to 2024 fishing opportunities for Ireland.

This is an important step in Ireland’s preparation for the annual fisheries negotiations and is an opportunity for the minister to hear the views of the Oireachtas Committee before the negotiations commence later this month.

A Co Meath angler has been found guilty of two breaches of fisheries legislation for illegal fishing in an area around the Blasket Islands.

Joseph Foley from Trim, Co Meath was observed trolling for protected bluefin tuna off the Kerry coastline using specialist gear including spreader bars, squid lures and game fishing reels.

Fisheries officers boarded his vessel, the Evie Rose, at the mouth of Valentia Harbour on 27 August 2022 and located the equipment stored throughout the boat.

Foley pleaded guilty to two charges: surface trolling from a vessel used for sea angling targeting or catching any species fish under Bye-Law No 981 of 2020 (Control of Sea Angling Method for Certain Species of Fish); and using a boat as an aid to the commission of an offence, contrary to the Fisheries (Consolidation) Act 1959 as amended.

He was convicted at Caherciveen District Court on Thursday 8 June and fined €400 for the breach of Bye-Law No 981/2020. The second charge was marked “taken into consideration”.

An order of forfeiture was made of the fishing gear seized and Foley was ordered to pay €200 costs.

The court was informed of the seriousness of the offences and that recreational fishing for Atlantic bluefin tuna in Irish waters is prohibited unless licensed as part of a limited and tightly controlled ongoing research project.

The court heard that Foley had no previous convictions and had cooperated with fisheries officers.

Commenting after the case, Sean Long, director of the South-Western River Basin District at Inland Fisheries Ireland (IFI) said: “Recreational fishing for Atlantic bluefin tuna in all Irish waters is strictly prohibited.

“This was an intelligence-led operation. It enabled officers to detect and intercept the Evie Rose and ensure that these important species are protected from illegal fishing.

A tightly controlled licensed research project, studying the movements and abundance of Atlantic bluefin tuna (Tuna CHART) has been underway between July and November annually since 2019. Such illegal angling jeopardises the potential for a viable recreational fishery in the future.

“I wish to acknowledge the vigilance and perseverance of IFI local fisheries officers in this instance.

“Inland Fisheries Ireland continues to encourage members of the public and anglers to report illegal fishing, water pollution, fish kills, or fish in distress, to its confidential 24/7 phone number, 0818 34 74 24.”

Three men have been found guilty of illegally fishing for Atlantic bluefin tuna off Baltimore Harbour in West Cork.

Brian Hassett from Monkstown, Co Cork; Barry Keohane from Blackrock, Co Cork; and Conor Jones of Kildinan, Co Cork were found guilty of illegally fishing for Atlantic bluefin tuna in waters south of Baltimore Harbour on 10 October 2022.

All three entered guilty pleas at Skibbereen District Court at a hearing on Tuesday 14 March.

The court heard evidence from Inland Fisheries Ireland (IFI) officer David Lordan, who said he observed the men using a spreader-bar lure system for around 70 minutes before their vessel entered Baltimore Harbour.

Despite an application for a return of the seized fishing gear, the court granted Forfeiture Orders in respect of all items seized.

Details were also presented of the importance of protecting Atlantic bluefin tuna and the research programme Tuna CHART, a catch-and-release tagging programme gathering scientific data through licensed recreational charters since 2019.

Hassett was found guilty of a breach of Section 285(a) of the Fisheries (Consolidation) Act 1959 and fined €1,000. He was also found guilty of breaches of Article 4 (a) and 4 (b) of Bye Law 981 of 2020, which were taken into consideration.

Keohane and Jones were found guilty of breaches of Article 4 (a) and 4 (b) of the 2020 Bye Law, and both men received the benefit of the Probation of Offenders Act on bonds of €5,000 each for a period of three years.

Commenting after the case, Sean Long, director of the South-Western River Basin District at IFI said: “I want to praise the vigilance of the fisheries officers involved in this operation.

“Illegal fishing for Atlantic bluefin tuna jeopardises the potential future for sustainable catch-and-release angling fishery, currently valued at €1 million annually, for professional skippers and for rural coastal communities.

“I continue to encourage members of the public to report incidents of illegal fishing, water pollution and fish kills, to Inland Fisheries Ireland’s 24-hour confidential hotline number on 0818 34 74 24.”

Ireland’s Tuna CHART bluefin tuna sea angling survey programme for 2023 has opened for charter skippers to apply.

Anglers in Ireland will once again have the opportunity to catch and release bluefin tuna in 2023 through the continuation of the Tuna CHART (CatcH And Release Tagging) programme that has been in operation around our coast since 2019.

Experienced charter skippers are now invited to apply to take part in this year’s Atlantic bluefin tuna scientific survey programme of Irish waters.

Building on the successes of the Tuna CHART programmes of 2019-2022, this scientific data collection catch-and-release fishery for Ireland will again operate in 2023.

A maximum of 25 authorisations may be granted to qualifying angling charter vessel skippers around the Irish coast for this fishery, which opens on 1 July and closes on 12 November.

The Tuna CHART programme is a collaborative scientific programme between Inland Fisheries Ireland (IFI) and the Marine Institute in partnership with the Sea Fisheries Protection Authority, Department of Agriculture, Food and the Marine (DAFM) and Department of Environment, Climate and Communications (DECC).

Between 2019 and 2022, some 1,500 Atlantic bluefin tuna were caught, tagged, measured and released off the Irish coast by authorised charter skippers. The largest tuna tagged to date in the programme was 2.75 metres, weighing an estimated 372kg.

All tuna were carefully managed in the water alongside the charter vessel, subject to strict guidelines set by the Tuna CHART programme, and all were released alive.

Data from the tagging programme have been collated by the partnership for reporting to the International Commission for the Conservation of Atlantic Tuna (ICCAT).

The core aim of the Tuna CHART programme is to collect data and tag these large fish, which is underpinned by ensuring good fish welfare, leading to successful release of the bluefin tuna.

Authorised skippers will be required to collect data on every bluefin trip undertaken and each bluefin tuna they catch, tag and release and their angling and data recording expertise is an important part of the overall survey programme. They will also be required to have high specification rods, reels and line in advance of the open season in order to ensure that the fish is brought alongside the vessel to be measured and tagged in the water in a timely manner.

Anglers will have an opportunity to participate in this fishery and contribute to this important scientific study by chartering and fishing from authorised vessels only.

Unauthorised vessels are not permitted to target or catch Bluefin tuna and any unauthorised person found to be targeting Bluefin tuna is liable to prosecution.

Experienced charter skippers are being invited to apply to join the 2023 Tuna CHART programme between Tuesday 21 March and Tuesday 4 April by filling out an application form online at www.fisheriesireland.ie/bluefin.

Minister for Marine Charlie McConalogue has promised to seek a quota of bluefin tuna for Ireland at the December EU fisheries council.

Large numbers of bluefin tuna have been reported by fishermen off the Irish west coast in recent years, but Ireland has no quota to catch the species- apart from a licensed catch and release programme for deep sea angling.

The tuna shoals have attracted Japanese and Korean vessels to the Irish coast outside the 200-mile EEZ, while Croatia, Cyprus, France, Greece, Italy, Malta, Portugal, and Spain are among EU member states which have quotas.

Britain has now been awarded a quota of 63 tonnes of bluefin tuna for 2023-2025

Mr McConalogue noted that an increased total allowable catch of bluefin tuna has been agreed as part of a new management plan adopted at the recent International Commission for the Conservation of Atlantic Tunas (ICCAT) meeting.

“Following discussions on this new management plan, the UK was granted an additional 15 tonne of bluefin quota and now has a quota of 63 tonnes of bluefin tuna for 2023-2025,” he said.

He said that Ireland had made clear to EU member states and the European Commission at EU internal meetings that Ireland considers that there is a case for an allocation of part of the increase in the bluefin tuna quota to be made available to Ireland for a targeted fishery.

“Given the prevalence of bluefin tuna in Ireland's EEZ, this is a request that we wish to be considered at council,” he said.

“I have therefore requested the opening of discussions at EU level to progress our case and I will be making a formal statement to this effect at next week's December Agrifish Council,” he said.

The EU share of global bluefin quota has increased in recent years to almost 20,000 tonnes.

The lack of a quota for Ireland was recently raised at Kerry County Council where Fianna Fáil councillor Michael Cahill said that not having a share of the bluefin quota is "a major missed opportunity for our fishing industry, including deep sea anglers".

An Atlantic bluefin tuna hooked off the Pembrokeshire coast recently is believed to be the biggest fish ever caught in Welsh waters.

As Wales Online reports, the 900lb (408kg) monster catch was made by Simon Batey and Jason Nott while returning from an angling trip in the Irish Sea.

Keeping the tuna in the water, they recorded a measurement of 111 inches (2.82 metres) from nose to tail before releasing it back into the sea.

The anglers were on a boat from White Water Charters which is licensed to catch, tag and release Atlantic bluefin tuna as part of a Welsh government programme similar to the Tuna CHART scheme in Ireland.

Experienced charter skippers can now apply for Ireland’s 2022 bluefin tuna scientific survey programme, as scientists confirm that over 1,100 of the largest tuna in the world have been successfully tagged and released through the programme in the last three years.

Building on the successes of the Tuna CHART (CatcH And Release Tagging) programmes of 2019-2021, this scientific data collection catch and release fishery for Ireland will operate again this year, subject to Covid-19 restrictions.

A maximum of 25 authorisations may be granted to qualifying angling charter vessel skippers around the Irish coast for the fishery, which will open on 1 July and close on 12 November.

The Tuna CHART programme is a collaborative scientific programme between Inland Fisheries Ireland and the Marine Institute in partnership with the Sea Fisheries Protection Authority, Department of Agriculture, Food and the Marine (DAFM) and Department of Environment, Climate and Communications (DECC).

Between 2019 and 2021, some 1,136 Atlantic bluefin tuna were caught, tagged, measured and released off the Irish coast by authorised charter skippers. The largest tuna tagged to date in the programme was 2.75 metres, weighing an estimated 372kg.

Anglers in Ireland are taking part in a unique ‘catch, tag and release’ programme to help Irish and international scientists learn more about the largest tuna in the world — the Atlantic bluefin tuna.

Under the Tuna CHART (CatcH And Release Tagging) programme, recreational anglers on board 22 authorised charter vessels the successfully applied to join the scheme this year will catch bluefin tuna and skippers will be tagging and releasing them back into the sea, alive, from this month to mid November.

The data collected on board authorised vessels will then be used for scientific assessment to improve knowledge of population structures, fish size and how bluefin tuna is distributed in Irish waters and throughout the North Atlantic.

Migrating through North Atlantic waters, bluefin tuna frequent Irish coastal waters to feed. Bluefin is an iconic sports-angling species and can grow up to 1,500lbs (around 680kg).

Under strictly controlled conditions, 685 bluefin tuna were caught, tagged, measured and released through the Tuna CHART programme in 2020. All bluefin tuna were caught by anglers in Irish coastal waters and then tagged by skippers. The fish is always kept in the water to ensure correct handling and tagging.

The largest tuna tagged in Ireland in 2020 was 2.75 metres long, estimated to weigh over 800 lbs (approximately 360 kgs).

Now in its third year, Tuna CHART is a collaborative scientific programme between Inland Fisheries Ireland and the Marine Institute in partnership with the Sea-Fisheries Protection Authority, the Department of Agriculture, Food and the Marine and the Department for Environment, Climate and Communications.

Environment Minister Eamon Ryan said: “The 22 angling vessels authorised by my department will contribute substantially to essential Bluefin tuna data collection as they migrate along the Irish coastline.

“The recreational fisheries sector is crucial in the delivery of this data collection programme and we look forward to continue working with all the State agencies involved.

“I want to acknowledge the key role of the authorised charter skippers and their crews who are bringing their unique expertise to bear on providing valuable data for scientific purposes, and the ‘citizen scientist’ anglers who will catch the fish. The fact that 685 fish were tagged last year with no mortalities recorded is a great achievement by the skippers.”

‘This programme also provides our coastal communities with access to a highly desired angling market that will bring a new demographic of tourists to our spectacular Wild Atlantic Way’

Marine Minister Charlie McConalogue welcomed the continuation of the programme for 2021.

“As a Donegal man, I have a keen interest in the bluefin tuna data collection programme,” he said. “I am delighted at the ongoing success of this programme as it allows our scientific partners in the Marine Institute and Inland Fisheries Ireland to collect valuable data and improve our understanding of the migratory patterns of bluefin tuna in Irish waters in a tightly controlled environment.

“This programme also provides our coastal communities with access to a highly desired angling market that will bring a new demographic of tourists to our spectacular Wild Atlantic Way.

“I am particularly pleased with the large increase in data collected in 2020, despite the restriction in place as a result of Covid and am anticipating an even more successful season this year thanks to our experienced skippers who have received authorisations for 2021.”

This year’s authorised vessels will operate out of ports in Donegal (Killybegs and Bundoran), Sligo (Rosses Point and Mullaghmore), Galway (Cleggan and Rossaveal), Clare (Carrigaholt and Kilrush), Cork (Courtmacsherry, Kinsale, Ballycotton, Union Hall, Great Island in Cobh, Baltimore and Youghal) and Waterford (Dungarvan).

All skippers have been fully trained while vessels have been fitted with a customised GPS device. Data is collected by skippers digitally by means of a specifically designed app.

Anglers looking to fish for bluefin tuna in Irish waters may only do so from an authorised charter vessel from now until 12 November 2021. The Sea Fisheries Protection Authority and Inland Fisheries Ireland are undertaking inspections and patrols around the coast to ensure that no unauthorised vessels are targeting or catching bluefin tuna.

Both organisations have also confirmed that any person engaging in fishing for bluefin tuna on a vessel which is not appropriately authorised, would be in breach of the Sea-Fisheries and Maritime Jurisdiction (Bluefin Tuna) Regulations 2019 (SI No 265 of 2019) and would face prosecution.

Like last season, skippers will have to adhere to any local or national COVID-19 public health guidelines that may be put in place. A full list of authorised skippers and vessels for the Tuna CHART programme in 2021 can be found at www.fisheriesireland.ie/bluefin.

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.”
