“Substantial progress” is being made in the recovery of gold bullion from a ship wrecked off Donegal nearly 80 years ago, as RTÉ News reports.

Atlantic Subsea Ventures is involved in the salvage operation at the Empress of Britain, a luxury ocean liner that was requisitioned for the war effort in 1939 and targeted by the Nazis the following year.

A number of such vessels are believed to lie in the depts around Ireland, with one in recent years — the SS Gairsoppa off Galway — giving up a record 48 tonnes of silver bullion seven years ago.

The Empress of Britain, which is believed to hold as much as €500 million in gold bullion, was found in 1995 but its location in deep waters precluded any salvage expedition, until now — thanks to remote-operated technology used in the oil and gas industry.

What’s proving a bigger stumbling block for the salvage company, it says, is Ireland’s 7.5% levy on recovered cargo which must also be held for a year and a day before it can be moved on.

#CostaConcordia - There were celebrations all round on the Tuscan island of Giglio early yesterday as the operation to raise the capsized cruise liner Costa Concordia was successful in lifting the ship upright, The Irish Times reports.

The video above captures in time lapse the dangerous and difficult 'parbuckling' operation that involved tying a sling of cables around the hull of the vessel in order to lift her bit by bit from the shallows off the Italian coast.

“This is the first visible sign of a job well done," said Franco Gabrielli, head of the authority co-ordinating the salvage operation. "We’ve taken a decisive step towards the moment when the ship can be towed away from the island.”

The Irish Times also quoted Titan Salvage MD Captain Rich Habib, who said: “This was a perfect job, it don’t get better than this...and sure, this will be part of shipping history because this was one of the most difficult salvage jobs of recent times...”

The next step in the salvage of the ill-fated Costa Concordia is to repair some of the severe damage to the side of the ship that has spent more than 18 months submerged, in order to get her seaworthy enough for transport to the port town of Piombino where she will be scrapped.

#CostaConcordia - The salvage master charged with righting the ill-fated cruise liner Costa Concordia has spoken of the risks involved in the task.

Still lying in her side on the Italian coast off Tuscany after grounding in the shallows on the night of 13 January 2012, the Costa Concordia is set to be lifted from the water by a specialised team headed by Captain Nick Sloan.

According to The Irish Times, their job goes by the name of the Parbuckling Project, and involves tying a sort of sling around the vessel using cables in order to raise her from the sea bed - a delicate operation due to the size of the vessel, and its resting place among jagged rocks.

Speaking candidly with The Guardian after a press conference in Rome on Thursday to discuss the operation scheduled for this coming week, South African salvage expert Capt Sloan said there is a "90% plus" chance the plan will work.

"The more we found out about the ship the more scared we got," he added, referring to the major clean-up operation in and around the shipwreck in the 18 months following the tragedy that claimed 32 lives and saw thousands of passengers - including an Irish couple - brought to safety in a major rescue operation.

Francesco Schettino, the Italian captain of the Costa Concordia, will face trial on charges of manslaughter and causing the loss of his ship after failing to reach a plea deal with prosecutors.

#Astrid - The Irish Times reports that marine salvage experts met on Friday with insurers of the Dutch tall ship Astrid to determine a wreck removal plan for the sunken vessel.

The sail training ship, which was taking part in The Gathering Cruise around Ireland, capsized after hitting rocks inside the Sovereign Islands near Kinsale in Co Cork on the afternoon of Wednesday 24 July.

All 30 crew on board - including a number of teenage sail trainees - were brought to safety by RNLI lifeboats from Kinsale and Courtmacsherry in a major rescue operation.

As previously reported on Afloat.ie, investigations got under way last Thursday 25 July to determine what caused the 42-metre brig to run aground at the mouth of Oysterhaven harbour.

Despite strong winds and rough seas at the time of her foundering, the Astrid remains largely intact apart from rips along the hull.

And according to expert salvage diver Colm Harrington, the 95-year-old ship will be salvageable - using slings to lift the vessel from the water.

However, the severity of the damage sustained means that it's unlikely the Astrid will be restored to her former glory.

The Irish Times has much more on the story HERE.

#TITANIC - The Titanic is for sale - if you have a spare $189 million to spend, according to the Los Angeles Times.

The single-lot auction, which will take place in April on the 100th anniversary of the Belfast-built ocean liner's tragic demise, includes more than 5,000 items salvaged from the wreck, from gold coins and clothing to parts of the ship's hull itself.

But casual buyers need not apply, as aside from the multi-million-dollar outlay, the prospective purchases must also take on stewardship over the collection, preserving it for future generations and exhibiting parts of it to the public.

Arlan Ettinger, president of Guernsey's Auctioneers & Brokers in New York, commented: "It's like getting a puppy. When you bring it home, you don't think of all the responsibilities and the time and investment that will be required... But it takes great care."

Images of the items up for auction are available HERE.

Last night, Lough Derg RNLI lifeboat, Toshiba Wave Warrior, was requested by Valentia Coast Guard to go to the assistance of 1 person, on board a 33ft cruiser on rocks after suffering engine failure, and which was now taking on considerable amounts of water. Mathew Gallagher, skipper of Aftermath was standing by, but was unable to get close to the casualty.

At 17.54hrs the lifeboat, with helm Eleanor Hooker, Colin Knight and Ger Egan was launched. The lifeboat carried its salvage pump, and in addition, Lifeboat Operations Manager, Charles Stanley-Smith made contact with Fergal Kerney, Lifeboat Deputy Launching Authority, who agreed to take a second salvage pump to Portumna by road.

At 18.15hrs the lifeboat was alongside the casualty vessel which was listing to port and on rocks. There were two persons on board (the skipper has been joined by a friend, a marine mechanic). The lifeboat transferred an RNLI crew member and the salvage pump to the casualty vessel and the lifeboat salvage pump was immediately put to work. The cruiser Aftermath met Fergal Kerney and took him to the scene. At 18.21hrs the lifeboat transferred the second salvage pump to the casualty vessel, set up a tow and held off head to weather.

At 19.25, (it was now dusk) and with two pumps running, the vessel was not floated. At 19.34hrs, RNLI Lifeboat helm agreed one last attempt to float the vessel before taking all persons off. Eamon Egan, Marine Engineer, brought a third, larger pump to the vessel from Portumna. At 19:45hrs, when the boat was not floated with three pumps running, the lifeboat made the decision to take all persons off and advised Valentia Coast Guard of same. At 20.15hrs, the two persons from the casualty vessel were transferred onto Aftermath, who had offered to take them back to Portumna. The owner will attempt to refloat his vessel in daylight tomorrow. The lifeboat returned to station and was ready for service again at 21.10hrs.

Diving Asgard II

In September 2008 an iconic part of maritime Ireland silently and tacitly slipped beneath the surface of the Bay of Biscay near the idyllic island of Belle Isle writes Timmy Carey.

Asgard II was on a journey from Falmouth to La Rochelle for routine maintenance when it would succumb to its fate of a watery grave, thankfully captain Colm Newport was able to safely abandon the ship with the entire crew of 25.

Since 1981 Asgard II a beautiful brigantine designed by Jack Tyrell and built in Arklow had served the Irish nation with distinction all over the globe, providing sail training for over 10,000 people; the image of the bright green hull and white sails becoming synonymous with Irish sailing.

In addition to such a proud history, Asgard II also carried on the name and traditions of Asgard; which played such a pivotal role in Irish history and in the foundation of the state. In Norse religion Asgard was the home of the Norse gods and it is fitting that a vessel with such an auspicious name would later be called "the harbinger of Irish freedom" by the President of Ireland Eamonn De Valera.

Asgard was built in 1905 in larvik and was a wedding gift from Dr and Mrs Hamilton Osgood of Boston to their daughter Mary and her husband Erskine Childers (the father of the future president of Ireland). In a magnificent feat of seamanship (which was reminiscent of his famous novel the riddle of the sands) Erskine Childers in the company of his wife and others expertly collected arms from Hamburg and landed them in Howth on the 26th of July 1914 for the Irish volunteers. In one of the great ironies of Anglo-Irish history Erskine Childers a decorated British war veteran would become an avowed Irish republican and would play a crucial role in the struggle for independence as minister for propaganda (being very highly thought of by both Eamonn De Valera and Michael Collins); before being executed in the Irish civil war.

In 1961 the Irish government purchased the vessel for sail training and in 1968 Coiste and Asgard was founded and was assigned responsibility for the vessel. With the launch of Asgard II, the original Asgard was transferred to the national museum where it has been expertly restored to its original glory and will in the future be available for general viewing.

With such a rich maritime heritage and being so deeply engrossed in Irish history popular view in late 2008 was that the Irish government would salvage Asgard II as a symbol of Irish pride; alas it would later be decided by the Irish government to abandon Asgard II with the uniquely Irish bowsprit of Grainne Uaile condemned to a permanent watery grave on foreign shores.

As with many diving expeditions, they often begin with a simple conversation and one late night a phone call from Eoin McGarry would begin with "what do you think of diving the Asgard II next year". Soon the idea generated its own momentum and a small team of Irish trimix divers (all of whom are CFT members) was assembled and preliminary plans were made for July 2010.

Despite the fact that no permission was necessary to dive the vessel under Irish or French law, it was decided to notify the Irish government of dive teams intentions to video the wreck and recover some of the artefacts for the Irish people. On contacting Coiste an Asgard the reaction of the board was very negative indicating that the artefacts were of little value and that due to the depth involved they were not in favour of any dives taking place.

A little disillusioned it was decided to make representations directly to the Minister for Defence and soon a government TD with a real interest in Irish history discussed the idea with the Minister for Defence Willie O Dea.

asgard_name

The ships name looming out from the darkness

In early February the dive team would receive a personal letter from the minister indicating that "enquiries are being made into the matter and I will write to you again shortly". In addition a TD had also confirmed to the dive team that the minister had indicated that he thought it was a great idea and wished the dive team well. Unfortunately within a very short time period the minister had to resign and the dive team received no further correspondence.

With the Irish government engrossed in an economic recession of epic proportions, the dive team decided to proceed before the ships artefacts were removed by foreign dive teams and lost to the state forever.

With time ticking by the final team of Eoin Mc Garry as expedition organiser, Brendan Flanagan of Longford Sub Aqua club, Phil Murphy and Frank McKenna both of Kilkenny Sub Aqua and myself were assembled as the bottom divers. With an emphasis on keeping the costs down as the divers would be financing the trip, the decision would eventually be made to have one cover diver to help the divers kit up and look after all the surface logistics; this would also allow all the dive team travel together in the one vehicle and reduce the travel costs. Being a qualified mixed diver as well as native of Brittany; Stephane Portrait of Blackwater Sub Aqua Club would become an essential member of the dive team without whom the trip could not have been successful.

Over the coming months Stephane and Eoin would work tirelessly on the logistics, which would be vastly more onerous and detailed than an expedition to the Lusitania. As well as the small issues of organising ferries, accommodation, a dive centre and a dive boat; the dive team would also notify in writing the local mayor of Belle Isle, the local tourist office, the local lifeboat and the admiral of the French national lifeboat institution in Paris, the local council and the head admiral of the Atlantic fleet of the French navy of the dive teams intentions.

Our dive boat skipper Yann Quere being the secretary of the French national sailing organisation and a Moniteur 3 with FFESSM (the French equivalent of CFT in CMAS), would be of huge assistance and confirmed to the dive team that there were no restrictions in diving the wreck. In addition the Irish government had not even requested an exclusion order be placed on the site to preserve the Asgard II, meaning it could be legally dived by any dive team at any time.

During the last few weeks endless hours would be spent reviewing the vessels plans, photographs and video clips; trying to decide what obstacles could lay ahead in trying to video and photograph the wreck as well as removing the bell, helm and compass. Eoin would even go so far as contacting Tyrell's to get the specifications of how the wheel was fitted and what size bolts were used to bolt the bell on.

A specialist dive tool bag was then assembled with all anticipated tools colour coded and placed into the bag in the order of their anticipated use; to try and eliminate wasting any precious bottom time. Only a few weeks to go and word came that a French technical dive team also had their eyes set on the Asgard II, would we arrive to late and would all the artefacts have disappeared into the possession of French or British divers; only time would tell.

Being Jury president of the CFT Moniteur 3 test on Inisboffin the day before the trip to France, my preparation time was hardly ideal; getting home after 10 pm on Friday then having to blend several mixes and assemble camera and rebreather equipment; grab a precious five hours sleep and head for the ferry. Seeing familiar faces of friends and dive buddies all thoughts of fatigue soon evaporated in anticipation of a good weeks diving. During the last week Paddy Agnew also joined the group and would assist Stephane on the surface during the course of the week.

Arriving in the idyllic harbour of Belle Isle the sight of the Irish Tricolour flying from the tourist office on our behalf was a good omen. That evening our skipper told us the water would be warm, the sea flat calm and visibility would be at least 10 meters with ambient light at depth; and we headed to bed in good spirits for an early start. Leaving the harbour with a strengthening breeze we would soon be greeted by a stiff force five and with cylinders rolling around at the stern of our dive boat; conditions were marginal as a small blob at 84 meters showed up on the screen of the GPS.

Our next concern would be the number of prawn trawlers that were fishing quite close by in the direction we anticipated our decompression station moving. With the Bay of Biscay having notoriously unpredictable weather it seemed that we would be treated to diving conditions more reminiscent of the south coast of Ireland. After an arduous time kitting up in a pitching sea in a dive boat, which doesn't normally cater for technical divers; the cooling effect of the sea came as welcome relief as Eoin Mc Garry and I dived first. Eoin would be taking video footage and I would be taking stills with my Ikelite camera housing rated to 60 meters, hopefully it would not leak at 84 metres! (at least the strobe was rated to 90 meters).

Dropping through layers of water the temperature soon dropped from 19 on the surface to 9 degrees Celsius at depth, the biggest surprise however being the visibility. Beyond 60 meters ambient light disappeared and visibility reduced to less than 1.5 meters; Irish diving conditions indeed. Landing on the Asgard II we could immediately see that our anchor line was perilously attached to the wreck and in danger of coming loose: something that was soon rectified. After adapting ourselves to the conditions it was good to see that my camera was surviving at 9 bar (at least for the moment) and we soon set off taking footage with Eoin taking video. Dropping down past the stern came the worm encrusted letters of Asgard II and swimming the length of the vessel it was soon apparent that she was in a sorry state. Both masts had collapsed and she had been badly damaged by trawlers; with one mast landing on the compass binnacle and the roof of the chart completely missing and almanacs aplenty neatly stacked in the shelves.

Amid the books and almanacs and nestled with a menacing grimace a large conger eel now stood sentinel in its new citadel. At the bow area it was a sorry sight to see the bowsprit of Grainne Uaile partially hidden by old sail, doomed forever to the seafloor. Swimming astern the sight of the ships helm still lashed was an amazing image that would cause all divers to become exuberant and all too soon our precious bottom time had elapsed and it was time for the mandatory 2 hours of decompression. Passing the second dive team who were also taking video footage the warm thermo clime was a welcome change from Irish diving conditions, but a strong surface current soon tempered that dramatically.

Back at the decompression station it was a strange sight to see that the strength of the current had orientated the decompression station at a 45-degree angle and instantly knew that the first hours decompression would be far from comfortable (until the second dive team had set the decompression station free in the current). Looking across at Eoin I could see the sight of the ships compass nestled safely in a bag, eliminating one of the objectives for day two. Surfacing to warm sunshine and with greatly moderated sea conditions we were soon planning dive objectives for day 2, pondering the difficulties of removing the ships bell and helm.

On unloading the boat back at Belle Isle we would have two groups of visitors, both unexpected. The first group were survivors of the sinking who had returned to Belle Isle sailing aboard the magnificent Le Belem and soon we were showing them the footage of the vessel they so hastily had to abandon.

The sight of two gendarmes taking to Stephane had the rest of us wondering what was happening, when it quickly emerged that a complaint had been received by the French police from an Irish government agency asking for the diving to be halted. While the rest of us blended gas and organised logistics for day two, Eoin and Stephane had very cordial discussion with French gendarmes who said we might not be able to dive the wreck later in the week.

The next morning with a 6 am start we were soon heading for the wreck site (with the Irish tricolour again flying from our dive boats mast) and were soon onsite. With the possibility of only one dive left on the Asgard II, dive objectives had to be reassigned and all divers were again assigned to two dive teams and we were soon descending a shot line in strong currents.

Approaching the ships hull seeing bubbles coming from my cameras strobe were not a welcome sight and I wondered would it work filled with seawater and found it did. The camera housing rated to 60m meters survived both dives unscathed; with the expert advice I had received on underwater photography earlier in the year from Ivan Donoghue, Simon Carolan and Nigel Moyter proving invaluable on the trip.

During this dive the dive team would again get video footage, which was given to the marine casualty investigation board for their report as well as getting more stills footage. Frank Mc Kenna soon had the ships bell and bracket removed and soon it was attached to a lifting bag and heading for the surface 84 meters above. Eoins' huge amount of prior research was soon hugely rewarded when the ships helm was also heading to the surface where Stephane Portrait was waiting to recover them.

The final act of the dive team would be to leave an Irish tricolour on a vessel whose name has such symbolism in Irish history, when Irish men and women overcame impossible odds to defeat the greatest empire on the globe to establish an Irish state after 700 years of struggle. The tricolour left draped on the wreck had been a gift from an ex member of the Irish Defence Forces and had last flown over and Irish Military Establishment and would serve as a fitting tribute to a vessel that had so eloquently represented Ireland in a maritime setting. Back aboard our dive vessel it was good to see that everyone had completed their decompression safely and that all objectives had been completed, with Stephane doing Trojan work for the bottom divers.

Once back ashore we would be astounded to hear of sensationalist newspaper headlines back home; giving a completely inaccurate version of events. That evening Eoin and Stephane would declare the artefacts to the equivalent of the French receiver of wrecks and would be told that the matter had been referred to the commodore of the local French naval base in Brest.

The following day the gendarmes would give the dive team a copy of a fax from the French naval base which confirmed that the dive team had broken no laws French or otherwise as we had known all along and the French gendarmes apologised for any inconvenience caused (that they had been acting on a fax from an Irish government body which was furnished to the dive team) and wished the dive team well.

Over the next few days of pleasure diving shallower wrecks two surprises would arise; the first that the visibility at the other end of the island was in stark contrast to that where the Asgard II lies and was typically twenty meters at depth!!! and secondly that the artefacts that we had previously been told were valueless were now suddenly of huge interest to Coiste an Asgard. Indeed it would puzzle everyone on the dive team at how helpful the French authorities were which was in stark contrast to their Irish counterparts; whom it would seem would have preferred to see these items disappear into the hands of continental or British dive teams. In the interim Eoin had got expert archaeological opinion in how best to preserve the wheel and spent a considerable sum of his own money in making a specialist box to ensure we could transport it in a wet condition back to Ireland.

Once back home the huge cascade of congratulatory messages to the dive team was a nice boost and made all the financial and personal sacrifice very worthwhile, as the volume of people with an interest in Irish maritime affairs soon became apparent. Back on Irish soil, the artefacts were registered with the Irish receiver of wrecks and handed over to him in custody as per maritime and salvage law. Hopefully in time these symbols of Irish maritime history and pride will be put on permanent display in a fitting venue such as the national museum next to the original Asgard or in Dun Laoghaire at the national maritime museum; where the 10,000 trainees who first learned to sail a tall ship aboard Asgard II can again hold that famous wheel or ring the bell.

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.”
