Displaying items by tag: Tuna CHART

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.

“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.

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.

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.

Building on the success of pilot programmes in 2019 and 2020, the Tuna CHART (CatcH And Release Tagging) fishery to collect scientific data on bluefin tuna will return in 2021, subject to COVID-19 restrictions.

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 (DAFM) and the Department of Environment, Climate and Communications (DECC).

In 2020, the Tuna CHART programme authorised 22 charter skippers to operate a scientific fishery — in which anglers participated fully — to catch, tag and release bluefin tuna. These professional skippers were trained to tag, measure and record bluefin data.

Despite the limitations of the pandemic, 685 bluefin tuna were caught, tagged and released around the Irish coast — a 230% increase in bluefin tagged on the previous year.

The most productive sites were the North-West and the South coast, mainly the waters of the Cork coastline. As many as 11 bluefin were tagged on one angling trip, a new Irish record. The largest tuna tagged was 275cm, weighing an estimated 822lbs.

All tuna were carefully handled subject to strict guidelines set by the Tuna CHART programme and all were released alive. Data from the tagging programme has been collated by the partnership for reporting to the International Commission for the Conservation of Atlantic Tuna (ICCAT).

This year a maximum of 25 authorisations may be granted to qualifying vessels and skippers around the Irish coast for fishing between 1 July and 12 November. Applications are now open and will be accepted until 1pm on Friday 9 April.

Depending on the successful operation and review of this year’s fishery, it is intended that a scientific catch-and-release fishery may also operate in 2022.

The partnership says a core aspect of the Tuna CHART programme is the welfare and successful release of the bluefin tuna. Authorised skippers will 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.

Data collection for scientific assessment is the primary purpose of the fishery and will continue to be a key requirement for skipper participation in this scientific catch-and-release fishery, the partnership adds.

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.

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 will be prosecuted. Applications for authorisations are open to charter skippers only.

Twenty-two charter angling vessels have been granted authorisation to participate in a bluefin tuna data collection programme after a successful pilot last year.

The Tuna CHART (CatcH And Release Tagging) programme will see skippers catch, tag, measure and release Atlantic bluefin tuna for data collection purposes off the Irish coast.

The authorised vessels, which are located in Cork, Clare, Galway, Sligo and Donegal, will support an international scientific programme to increase knowledge of the behaviour and abundance of bluefin tuna in Irish waters and across its distribution generally.

Atlantic bluefin tuna, the largest tuna in the world, frequent Irish coastal waters to feed during the species’ annual migration through North Atlantic waters.

The bluefin tuna is prized by sea anglers for its power and fighting ability and is a very valuable commercial species, though there is currently no sport or commercial fishery for bluefin tuna in Ireland.

The new programme, which has been developed by Inland Fisheries Ireland and the Marine Institute in partnership with the Sea Fisheries Protection Authority and the former Departments of Agriculture, Food and the Marine, and Communications, Climate Action and Environment, will operate again in 2020 having commenced on a pilot basis in 2019.

Eamon Ryan TD, minister with responsibility for inland fisheries, said: “The 22 angling vessels authorised by my department, increased from 15 last year, 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 research 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 209 fish were tagged last year with no mortalities is a great achievement by the skippers.”

The Sea Fisheries Protection Authority and Inland Fisheries Ireland will undertake inspections and patrols around the coast to ensure this remains a strictly controlled programme.

Building on the success of last year’s Tuna CHART (CatcH And Release Tagging) pilot programme, a bluefin tuna research catch-and-release fishery for Ireland will operate in 2020.

A maximum of 25 authorisations may be granted to qualifying angling charter vessel skippers around the Irish coast for this fishery which will open on Wednesday 1 July and close on Thursday 12 November, without exception.

And depending on the successful operation and review of this year’s fishery, it is intended that a scientific catch and release fishery may also operate in 2021 and 2022.

Atlantic bluefin tuna, the largest tuna in the world, frequent Irish coastal waters to feed during its annual migration through North Atlantic waters. The bluefin tuna is prized by sea anglers for its power and fighting ability and is a very valuable commercial species.

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, the Department of Agriculture, Food and the Marine (DAFM) and the Department of Communications, Climate Action and Environment (DCCAE).

In 2019, the Tuna CHART pilot programme authorised 15 charter skippers to operate a scientific fishery, in which anglers participated fully, to catch, tag and release bluefin tuna.

These professional skippers were trained to tag, measure and record bluefin data and over the course of the 2019 three month season, 219 bluefin tuna were caught, tagged and released. As many as eight bluefin were tagged on one fishing trip.

All tuna were carefully handled subject to strict guidelines set by the Tuna CHART programme and all were released alive. Data from the tagging programme are being collated by the partnership for reporting to the International Commission for the Conservation of Atlantic Tuna (ICCAT).

As with the pilot programme, this year’s authorised skippers will be required to have high specification rods, reels and line in advance of the open season in order to bring the fish alongside in a timely manner. Skippers will be required to collect data on every bluefin trip undertaken and each bluefin tuna they catch, tag and release.

A call for applications for the 2020 fishing season will be announced next Tuesday 18 February and the last date for the receipt of a completed application will be 1pm on Friday 6 March.

Fifteen angling vessels will soon be granted authorisation to participate in Tuna CHART (Catch and Release Tagging), a pilot Bluefin Tuna Data Collection Programme.

As previously reported for Afloat.ie by Lorna Siggins, the programme will see the 15 authorised vessels catch, tag and release Atlantic bluefin tuna for data collection purposes off the Irish coast.

These vessels, which are located in Cork, Clare, Galway, Sligo and Donegal, will support scientific work to increase knowledge of the behaviour and abundance of bluefin tuna in Irish waters — which currently do not host a sport or commercial fishery for the species.

The new programme, which has been developed by Inland Fisheries Ireland (IFI) and the Marine Institute in partnership with the Sea Fisheries Protection Authority (SFPA), the Department of Agriculture, Food and the Marine and the Department for Communications, Climate Action and Environment (DCCAE), will operate on a pilot basis this year.

Authorisations will be granted from mid-August until mid-October, and all skippers and trained crew have participated in training with guidance provided around fish handling, welfare, tagging and data recording.

Participants in the programme will catch, tag and release bluefin tuna while adhering to strict fish safety and handling procedures at all times.

Marine Minister Michael Creed has welcomed the initiative. “My department has been working on this project for two years at both EU and domestic levels and I am happy to announce the commencement of the project this month,” he said.

“This initiative will allow the Marine Institute and Inland Fisheries Ireland to collect valuable data on the migratory patterns of bluefin tuna in Irish waters in a tightly controlled environment.

“This project has been a wonderful example of co-operation between my department, DCCAE, SFPA, IFI and the Marine Institute and I am looking forward to the continued development of this relationship.”

Sean Canney, Minister with responsibility for inland fisheries, added: “The angling vessels which will be receiving authorisation from my department will contribute in a very tangible way to important data collection around Bluefin tuna as they migrate past the Irish coastline.

“The recreational fisheries sector is crucial in the delivery of this pilot programme and we look forward to working with all the State agencies involved and critically with the skippers and their crews who have received authorisations in providing valuable data for scientific purposes.”

The SFPA and IFI will undertake inspections and patrols around the coast to ensure this remains a strictly controlled fishery.

Anglers wishing to engage in this fishery must only do so on a sea angling vessel specifically authorised to participate in the pilot programme. Any person engaging in this fishery on any vessel which is not appropriately authorised will be in breach of the Sea-Fisheries and Maritime Jurisdiction (Bluefin Tuna) Regulations 2019 (SI No 265 of 2019).

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.”
