#FERRY NEWS-A month from today sees the resumption of fast-ferry sailings on the Dun Laoghaire-Holyhead route, operated by Stena Line's HSS Stena Explorer, writes Jehan Ashmore.

The 120 minute central-corridor route closed in mid-September due to consistent high operating costs in recent years. This led to the withdrawal of the fuel-thirsty HSS craft which is powered by four gas-turbine engines.

In addition most of the route's turnover was generated in the high season months, leaving the remaining months unsustainable. As such the company decided to make the service as a seasonal-only operation. To read a previous report of the closure click HERE.

The ending of the year-round-service was the first major break to the route since the introduction of the pioneering HSS Stena Explorer in 1996 which in turn had replaced conventional tonnage. The Finnish built craft was the first of a trio of sisters commissioned for Stena Line and only this vessel remains in service for the operator.

Also operating on the route in recent years was the smaller fast-ferry craft Stena Lynx III which had served several high and low seasons, though she  will not be joining her larger fleetmate. The Tasmanian built Incat fastcraft was sold last year to South Korean interests as previously reported on Afloat. ie

Meanwhile the company's Dublin-Holyhead route is maintained by conventional tonnage vessels, Stena Adventurer and Stena Nordica which operate the 3 hour 15 minute service.

Irish Sea fast-ferry Stena Lynx III (1996/4,113grt) which has been laid-up in Dun Laoghaire Harbour since last month has been sold to interests in South Korea. Renamed Sunflower 2 and flying the flag of the Far-Eastern nation, she departed yesterday afternoon on a delivery voyage expected to take around twenty-five days, writes Jehan Ashmore.
The Dublin Port pilot cutter Camac was in attendance as the 650 passenger/153 vehicle fast-ferry departed at 16.20hrs. She is re-registered in Busan, South Korea's second largest city, located in the south-east, where she is to operate to the island of Jeju off the country's south-west coast.

Sunflower 2 is to make bunker calls on the repositioning voyage, firstly in Valletta, Malta before she transits the Suez Canal to the Red Sea port of Jeddah, Saudi Arabia and Columbo, Sri Lanka. From there she transits the Strait of Malacca then through the South China Sea followed by the East China Sea before finally entering the Strait of Korea to her homeport of Busan.

Since 1999 she has served Stena Line's fast-ferry high-season Rosslare-Fishguard route sailings taking 1 hour 50 minutes in tandem with conventional ferry Stena Europe (1981/24,828grt) which currently maintains the year-round 3 hours 30 minutes route. It is believed that Stena Line will not be operating high-season fast-ferry services in 2012.

Prior to her Dun Laoghaire departure, her South Korean crew have been preparing the craft over the last three weeks. Notably there was the removal of all Stena Line corporate livery markings on the hull. Her new name and port of registry were painted at the stern though she retained her original name at the bow which included both symbols of an Irish shamrock aptly to starboard (green) and the Welsh dragon to port (red) to reflect her Irish Sea southern corridor route.

Stena Lynx III departing Dun Laoghaire last year, note her starboard 'Shamrock' at the bow.

In recent years on the St. Georges Channel route she was marketed as the Stena 'Express'. Her final sailing this year was 4 September and three days later she docked Dun Laoghaire at St. Michaels Pier. On the adjacent berth which is designed specifically for and only capable of accommodating the HSS 1500 class fast-ferries.

Stena Lynx III also ran several shoulder season stints on the Dun Laoghaire-Holyhead route with the HSS Stena Explorer (1996/19,638grt) only running during the busier summer months. During this summer all sailings were maintained by HSS Stena Explorer until the route became a seasonal-only service for the first time this year when the last sailing took place in mid-September. The HSS remains in layover for the winter in Holyhead at her dedicated berth. The route is due to re-open in April or May.

The 35 knot Stena Lynx III was launched from fast-ferry catamaran specialists InCAT Pty based in the Tasmanian capital of Hobart. Early in her career the 81m wave-piercing catamaran (WPC) craft served Dover-Calais followed by two seasons between Newhaven-Dieppe when renamed P&O Elite for joint operators P&O Stena Line.

Her predecessors the WPC InCat 74m Stena Sea Lynx, became the first car-carrying catamaran to operate Dun Laoghaire-Holyhead sailings in 1993. The pioneering water-jet propelled craft was replaced in subsequent years by the larger InCAT 78m Stena Lynx II.

She was replaced in 1996 when the revolutionary four gas-turbine engine water-jet propelled HSS Stena Explorer was introduced. A further two sisters of the HSS 1500 class (High-speed Sea Service) were completed by Finnyards in Rauma.

At 13.07hrs Stena Line's HSS 1500 fast-craft ferry HSS Stena Explorer pulled away from her berth for the last time this year on the Dun Laoghaire Harbour-Holyhead route, as she headed for the harbour mouth several crew members waved from the stern to shore-based colleagues on the link-span, writes Jehan Ashmore.
Only yesterday, sailings on the daily single-round trip operated route had to be cancelled due to adverse weather conditions on the Irish Sea caused by the tail end of Hurricane Katia. The decision with today's closure was made well in advance and comes as no surprise as the Stena Explorer (1996/19,638grt) "has traded at a financial loss for several years" according to her owners Stena Line. Around 53 staff in Dun Laoghaire will be affected by the decision.

The core reason to withdraw the HSS on the 120-minute route which is not to re-open until the 2012 season, rests with the high operating costs of the fuel-thirsty fast-ferry which is powered by four gas-turbine engines. In addition the route's generated most of its turnover during the period May-September, leaving the remaining months unsustainable, as such the company wants the route to be seasonal-only in the long-term.

Passengers and freight customers will instead need to use the company's other Dublin Bay route between Dublin Port and Holyhead. The 3 hour 15-minute central corridor route is served by two ro-pax vessels, Stena Adventurer (2004/43,532 grt) and Stena Nordica (2000/24,206 grt) which operate to a year-round schedule, for times click HERE.

What is not certain is the precise date for resumption of Dun Laoghaire-Holyhead services as Stena Line have only indicated that they hope to reopen in April or May nor it is outlined as to what type of fast-craft would operate the route next year.

With today's break in service for at least the next six months, this is the most significant absence of the revolutionary HSS (High Speed Sea Service) 1500 fast-ferry which made her official maiden voyage on the route from Dun Laoghaire on 10th April 1996. The only other notable occasions when the HSS was off-service was for the short spells to allow for annual dry-docking, refit, repairs or when the route in recent years was partially operated by Stena Lynx III.

The 1500 referred to the number of passengers the Stena Explorer could accommodate. She was the first of the three Finish-built HSS 1500 catamaran vehicle capable carrying craft to enter service on three routes from the UK. The next sister completed HSS Stena Discovery entered service in the same year between Harwich-Hook van Holland and the final of the trio HSS Stena Voyager entered the Belfast-Stranraer route in 1997. Several years ago the HSS ceased operating on the Dutch route and the HSS currently serving on the North Channel is due to be replaced by conventional ferries in mid-November as previously reported on Afloat.ie, to read more click HERE.

On the Dun Laoghaire-Holyhead service the HSS enjoyed the boom years, and at its peak there were five daily round trips. From 2006 onwards the routes fortunes began to decline due to the ending of duty-free sales, competition from low-cost airlines, and the increasing cost of fuel.

In order to stave off further losses, a series of cost cutting measures were implemented over the next five years. Firstly the sailing frequency was reduced then the passage times were increased to reduce fuel consumption at the expense of faster crossings. In addition the company resorted to withdrawing the Stena Explorer during the shoulder months surrounding the summer and as previously mentioned these sailings were covered by the Stena Lynx III.

When the Stena Explorer returned for the summer months, the Stena Lynx III switched to her normal high-season spell on Rosslare-Fishguard sailings in tandem with regular route vessel Stena Europe. This year she served as usual on the St. Georges Channel route with the last high-season sailing completed on 4 September.

Stena Lynx III remained initially at Fishguard until making a repositioning voyage to Dun Laoghaire via the Kish Lighthouse last Wednesday. She berthed adjacent to the now disused HSS berth link-span on St. Michaels Wharf. The Tasmanian built craft has spent previous winter layover periods in Dublin and last year in Dun Laoghaire whereas the Stena Explorer is expected to do so in her home port of Holyhead.

At the neighbouring Carlisle Pier, the former terminal where numerous steam-packets, 'mailboats' and the conventional Sealink/British Rail car-ferries served (the last being the Stena Adventurer better known as St. Columba built in 1977) there are plans for a national diaspora museum.

The centrepiece landmark building would form as part of the masterplan proposed by the Dun Laoghaire Harbour Company as part of a concerted effort to offset the reduced role of ferry operations. The masterplan is also to attract cruiseship business amongst other proposals envisaged.

Holidaymakers now have the added option of  fast-ferry sailings on Stena Line's Rosslare-Fishguard port route which is to resume tomorrow, writes Jehan Ashmore.
The high season service is operated by the fast-ferry Stena Lynx III which is marketed as the Stena 'Express' . The summertime service runs between 1 July - 4 September and the fast-ferry is scheduled to take 120 minutes for the crossing.
Stena Lynx III has a capacity for over 600 passengers and 120-cars, to see a virtual tour of the wave-piercing catamaran craft click HERE. Measuring 81m long the 4,113 gross tonnes craft was built in 1996 by fast-ferry specialists InCat in Hobart, Tasmania. In recent years she maintained sailings between Dun Laoghaire-Holyhead when the HSS Stena Explorer was temporily taken off service.

In addition to the 'Express' service the St. Georges Channel route is served by the year-round operated conventional ferry, Stena Europe (1981/24,828 grt). The 1,386 passenger / 564-vehicle ferry recently underwent a £2m refurbishment and takes a more leisurely passage time of 3 hours 30 minutes.

Fast-ferry Stena Lynx III departed Dun Laoghaire for Fishguard Harbour on a repositioning voyage today, writes Jehan Ashmore.

The 80m craft built in Hobart, Tasmania is due to dock at the Pembrokeshire port this afternoon in advance of seasonal sailings on Stena Line's Fishguard-Rosslare.The Stena 'Express' fast-ferry service is to resume in just over a fortnight's time. Sailings are scheduled to a daily single round trip between 1 July-4 September.

The 627 passenger / 120 car capacity fast-ferry will operate in tandem with the year-round operated conventional ferry-service served by the Stena Europe. Passage times are 120 minutes for the fast-ferry service while the Stena Europe takes 3 hours 30 minutes to sail across the St. Georges Channel.

In the same week that the fast-ferry takes up summer sailings from Fishguard, the small French flagged cruiseship Le Diament is to make the first of three calls in July and once in August.

The motoryacht-like vessel which can accommodate 226 passengers is the first cruise caller of the season and is run by the only French-owned cruise operator Compagnie De Iles Du Ponant.

Stena's Southern Sailings

Sailings on Stena Line's Rosslare-Fishguard port route remain for freight-users only until the passenger ferry returns from essential maintenance this week, writes Jehan Ashmore.
The passenger ferry Stena Europe is currently in dry-dock at the A&P Group's Falmouth facility and is scheduled to resume normal service with the first sailing at 14.30hrs from Fishguard on Thursday 7th April. The corresponding first outbound sailing from Rosslare is on the same day with the 21.15hrs sailing.

In the meantime freight-only ferry Stena Seafarer is operating the St. Georges Channel route having arrived at Rosslare on a repositioning voyage from Belfast on 29th March.

Stena Seafarer (1975 / 10,957grt) was one of a trio of freight-ferry sisters that served the Larne-Fleetwood port route until its closure in December. Like her sisters Stena Leader (1975 / 12,879grt) and Stena Pioneer (1975 / 14,426grt) they were built at the West German shipyard of J.J. Sietas in Hamburg.

Stena Seafarer's sisters remain laid-up in Belfast and with each vessel over 35 years in service it would seem likely there are nearing the end of their careers, at least on the Irish Sea.  

To provide additional passenger capacity the Stena 'Express' fast-ferry service will return to the southern corridor route between 1 July-4 September. The high-season sailings as usual will be operated by the InCat built Stena Lynx III which is to operate a daily single round trip in tandem with Stena Europe.

HSS Sailings Resumed

This year's first ferry sailing of the HSS Stena Explorer from Dun Laoghaire to Holyhead was disrupted yesterday due to 'technical reasons'.
The HSS (High Speed Service) fastcraft was scheduled to depart Dun Laoghaire at 13.15hrs but the sailing was cancelled. Passengers booked on the 19,638 tonnes fastcraft were transferred to Stena Line's neighbouring Dublin-Holyhead route, to take last night's sailing instead.

The Stena Explorer had completed her first sailing from Holyhead yesterday morning, the fastcraft having departed the Welsh port at 10.00hrs.

Due to the technical difficulties, the Stena Explorer was not in a position to accommodate passengers on the return crossing, though the fastcraft did depart Dun Laoghaire 'light' (without passengers) at 18.45hrs for Holyhead.

The Stena Explorer resumed service with this morning's 10.00hrs sailing from Holyhead to Dun Laoghaire.

The re-introduction of the Stena Explorer is to provide greater capacity during the summer season compared to the smaller Stena Lynx III, which previously served the route until early January. The HSS will operate the two-hour route with a daily single round trip up to 13 Setember.

Stena Line's HSS fast-ferry the Stena Explorer will be re-introduced on its Dun Laoghaire to Holyhead route this Friday, writes Jehan Ashmore.

The HSS (High Speed Service) operated 19,638 tonnes craft will run between 1 April to 13 September to cope with the additional demand over the summer period.

A single daily round trip is scheduled with a 10.00 hours sailing from Holyhead and a 13.15 hours sailing from Dun Laoghaire. Passage time is 120 minutes (2 hours).

The HSS can 350 vehicles and with 1500 passengers, the craft can handle higher volumes of seasonal summer foot passengers compared to the last route serving vessel, the 4,113 tonnes Stena Lynx III. The return of the HSS service links in with those intending to make onward journeys from Dun Laoghaire's DART commuter rail service to Dublin city centre and beyond on the national rail network.

Up to early January the route had been served by the Stena Lynx III which remains moored alongside Dun Laoghaire's St. Michaels Wharf. The craft which can take 627 passengers and 120 cars and marketed as the Stena 'Express' is to resume high season sailings starting in July between Rosslare-Fishguard.

In total the company carries over two million passengers on its four Irish Sea routes each year. An additional route between Belfast-Liverpool (Birkenhead) was taken over by the Swedish owned ferry company from DFDS Seaways late last year, is subject to regulatory clearance.

Until such clearance has been granted, this route will be operated separately from all other Stena Line routes. In the meantime the company advise until further notice to make bookings which will remain acceptable through the use of the DFDS website.

With just over a fortnight to go to resumption of Stena Line's Dun Laoghaire-Holyhead fast-craft sailings on 1 April, the route to Wales is to see the larger HSS Stena Explorer return instead of Stena Lynx III, writes Jehan Ashmore.
It was originally planned that the 4,113grt 'Lynx' craft would start the season while the 19,638grt HSS (High Speed Service) fast-craft would take over in June for the summer months.

According to Stena Line over 70% of its passengers business is carried by the HSS Stena Explorer in the high season. It is felt that the 1996 Finnish built fast-craft is better suited for the service due to a loyal customer base which was reflected by repeat bookings and their preference of the HSS craft on the 120 minute (2 hour) route.

A daily single round trip is scheduled with sailings from Dun Laoghaire to Holyhead departing at 13:15hrs. The corresponding sailing from the Anglesey port departs at 10.00hrs and arrives at the Irish port at 12 noon. Sailings will operate through the summer until 13 September.

From there on Stena will make a decision as to its continuing schedule, though it is widely believed that the prospects of the fuel-thirsty, expensive to run HSS fast-craft service are likely to be at an end of an era.

Last month negotiations over the core issue of harbour fees were held between Stena Line and Dun Laoghaire Harbour Company. It is understood that the annual fee of €6.5m was dropped to €2m. The board of the harbour company has given a 'conditional green light' of a new ferry contract to Stena Line to run the service for the next two years with an option of a third year.

The service closed for its seasonal break earlier this year on 5 January with the 'Lynx' going into temporary lay-up at Holyhead's inner harbour to join the HSS Stena Explorer. The HSS had been 'wintering' at the port since September sailings were taken over by the Lynx.

Earlier this month the Stena Lynx III came to Dun Laoghaire to continue her lay-up period. The 1996 Tasmanian built craft will stay there before resuming seasonal sailings between Rosslare-Fishguard in tandem with the conventional ferry Stena Europe.

In the meantime the craft is berthed at the harbour's two-berth ferry terminal at St. Michaels Wharf. The HSS berth is only designed for this type of fast-craft whereas the other berth now occupied by the Lynx was built originally for conventional ferries but was re-configured last year to suit the fast-craft.

Fast-ferry catamaran Stena Lynx III is to resume offpeak sailings on Wednesday (15 September)
on the Dun Laoghaire-Holyhead route, writes Jehan Ashmore.
The 'Lynx' had spent the high-season on St. Georges Channel in tandem with conventional
ferry Stena Europe on the Rosslare-Fishguard route. Prior to then the Lynx craft also served Spring
sailings on the Dun Laoghaire-Holyhead service as a replacement vessel of the HSS Stena Explorer.

The reasoning for the change of vessels on the central Irish Sea route during the Spring and
forthcoming Autumn /Winter seasons is a cost-cutting measure on behalf of operators Stena Line.
The larger HSS craft is becoming increasingly more expensive to run using fuel thirsty gas-
turbine engines, compared to the smaller capacity Stena Lynx III, which can be used instead
during the quieter months.

Stena Explorer is to be withdrawn with the last round trip sailing tomorrow (14 September)
departing Holyhead at 10.00hrs and arriving at Dun Laoghaire at noon. Correspondingly the HSS departs
the Irish port at 13.15hrs and returns to the Welsh port two hours later.

On the following day (15 September) the Stena Lynx III will make her first outbound departure
from Holyhead at 10.00hrs arriving Dun Laoghaire at 11.50hrs. After a turn-around period in the Irish port
the Lynx departs at 13.15hrs with an arrival to the Anglesey port at 15.05hrs.

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.”
