#MarineScience - Research vessel RV Celtic Explorer of the Marine Institute, is off to a renewed start in 2018, after undergoing a major refit.
The Romanian-Dutch built ship is ready to accommodate 18 scientific surveys throughout the year.
The five-year refit included an overhaul of the bow thruster and an upgrade of its DC propulsion system. The vessel's original fishing sonar was removed and a new Simrad SU92 fisheries sonar installed. The new sonar will have an increased range and resolution and a decreased noise level, which will be a huge advantage for the Marine Institute's fisheries research.
The vessel's accommodation also received an upgrade after 15 years of service with cabin floors refurbished and a new accommodation layout in the scientists cabins. The RV Celtic Explorer's refit also included painting and antifouling of the hull and complete painting of the superstructure as well as a major 60,000 hour overhaul of one of its main diesel generators .
The 65.5m vessel was in A&P yard in Falmouth, United Kingdom for the refit which started in mid in December 2017 and works were completed this month.
The RV Celtic Explorer came into service in 2003 and is designed for fisheries acoustic research, oceanographic, hydrographic and geological investigations as well as buoy/deep water mooring and ROV Operations.
Several deepwater ROV surveys will be undertaken in 2018, one led by Dr Louise Allcock from the National University of Ireland, Galway will investigate deep sea corals and sponges from a diversity of deep-water habitats.
Professor Andrew Wheeler from the University College Cork will explore and monitor cold water corals in the submarine canyons in the deep ocean and determine their sensitivity to climate change, fisheries and oil industry impacts.
A survey led by Professor Sergei Lebedev from the Dublin Institute for Advanced Studies will investigate the structure, evolution and seismic hazard of Ireland's offshore territory. Professor Lebedev's team will for the first time, deploy an array of ocean-bottom, broadband seismometers offshore, which together with existing arrays onshore will cover the entire Irish territory.
Dr Aggeliki Georgiopoulou from the University College Dublin will survey the structure and composition of the lower crust and mantle, as well as any hydrothermal activity RV Celtic Explorer off to a renewed start in 2018 at the Charlie Gibbs Fracture Zone, the largest geological fault in the northern Mid-Atlantic Range.
In 2018 the Marine Institute will also undertake acoustic surveys of Anglerfish and Megrim, Blue Whiting, Celtic Sea Herring and Boarfish on the RV Celtic Explorer. An INFOMAR-led survey will also map the physical features of the seabed in the Celtic Sea, using hydrographic techniques.

#MarineNotice - The Marine Institute advises that the annual Irish Groundfish Survey (IGFS2017) is being carried out off the South and West coasts of Ireland till Saturday 9 December in fulfilment of Ireland's Common Fisheries Policy obligations.
The IGFS is a demersal trawl survey consisting of approximately 125 fishing hauls of 30 min duration each in ICES area VIIb, VIIg and VIIj.
The vessel is displaying all appropriate lights and signals during the survey and is also listening on VHF Channel 16. It is towing a high headline GOV 36/47 demersal trawl during fishing operations.
Commercial fishing and other marine operators are requested keep a two nautical mile area around the tow points clear of any gear or apparatus during the survey period.
#MarineNotice - The Marine Institute advises that the annual Irish Groundfish Survey (IGFS2017) will be carried out off the North West Coast of Ireland between Tuesday 3 and Saturday 14 October, in fulfilment of Ireland’s Common Fisheries Policy obligations.
The IGFS is a demersal trawl survey consisting of approximately 45 fishing hauls of 30 minutes duration each in ICES area VIa. Fishing in 2017 will take place within a two nautical mile radius of these 45 positions, the approximate locations of which are noted in Marine Notice No 39 of 2017.
The survey will be conducted by the RV Celtic Explorer (Callsign: EIGB), which will display all appropriate lights and signals during the survey and will also be listening on VHF Channel 16. The vessel will be towing a high headline GOV 36/47 demersal trawl during fishing operations.
This survey is to determine the relative annual abundance and distribution of commercially exploited fish stocks, in particular assessment of recent recruitment. In addition, other species of national importance are sampled along with physical and chemical oceanographic parameters.
The Marine Institute requests that commercial fishing and other marine operators keep a two nautical mile area around the tow points clear of any gear or apparatus during the survey period outlined above.
While there is no statutory provision for the loss of gear at sea, the Marine Institute will make every effort to avoid gear, adequately marked according to legislation, that may be encountered in the notified areas. In the event that an operator has static gear or other obstructions within 2nm of the trawl points, it is the responsibility of the owner to notify the survey managers or vessel directly.
This should be communicated by identifying specifically which ‘Prime Station’ is of concern using the appendix and contact details provided in Marine Notice No 39 of 2017, a PDF of which is available to read or download HERE.
It is not required to provide positional details of commercial operations beyond 3-4nm of the survey points provided. Specifics of any fishing gear or other obstructions that are known and cannot be kept clear of these survey haul locations can be notified using the contact details provided in the above Marine Notice.
#SeaFest - Students from fourth class at Cregmore NS recently visited the RV Celtic Explorer in Galway Docks as part of their marine science and art project building up to SeaFest, Ireland’s national maritime festival.
Afloat.ie previously reported on the project, which places art, marine science and technology in the heart of the classroom in a re-enactment of the discovery of the Moytirra deep-sea hydrothermal vents in 2011.
On board the RV Celtic Explorer, up to 20 pupils experienced what it might be like to participate in an expedition at sea, as well as witness first-hand some of the equipment used in deep-sea exploration.
During the tour, led by Rosemarie Butler and Cushla Dromgool-Regan of the Marine Institute, the children learned about the recent climate survey of the mid-Atlantic and met with marine scientist Dr Louise Allcock of NUI Galway, who is studying cold water corals and sponges off the Irish continental shelf.
The students were also introduced to Paddy O’Driscoll, pilot of the unmanned ROV Holland I, who gave a live demonstration of how parts of the remotely operated submersible work.
“The enthusiasm the children showed about the ocean during their tour of the Celtic Explorer highlighted the importance of how school projects adopting different disciplines can be used in class in a very real and exciting way,” said Dromgool-Regan.
“The children’s high level of understanding about the ocean gained through the art and marine science project, where they discussed the geology of the ocean floor, concepts of climate change, along with deep sea creatures rarely seen by humans is a testament to the artists, scientists and teachers involved.”
Cregmore NS’s fourth class project, entitled Build Your Own Unknown, culminates with a film recreating the Moytirra vent discovery that will be premiered in the Kids Zone at Seafest 2017 before touring various education outreach centres around Ireland.
The RV Celtic Explorer will also be in Galway Docks for SeaFest with free tours available over the weekend from Friday 30 June to Sunday 2 July.
Visitors can keep track of all the activities taking place over the three-day festival with he new SeaFest Festival Guide app for iOS and Android devices.

#MarineScience - Marine scientist and researcher Dr Louise Allcock from NUI Galway is leading a team of 10 university researchers and students on a two-week deep-sea expedition researching cold water corals and sponges.
The team — who can be followed on the [email protected] blog – are currently exploring the Whittard Canyon, located 200 nautical miles south-west of Ireland at the edge of the continental shelf in the Atlantic Ocean aboard the Marine Institute’s RV Celtic Explorer, which recently returned from a climate change ‘health check’ of the Atlantic.
And the researchers are making extensive use of the Marine Institute’s ROV Holland I, deployed into areas where the sea floor rapidly drops from around 300m down to 3,000m.
“The researchers and students are seeing for the first time corals and sponges covering an area around the Whittard Canyon, Porcupine Seabight, Gollum Channel and the Belgica Mounds in Irish waters,” said Dr Olivier Thomas, a professor of marine biodiscovery at NUI Galway and co-ordinator of the National Marine Biodiscovery Laboratory located at the Marine Institute.
Dr Allcock added: “Using the ROV’s robotic and lighting capabilities, we are able to manoeuvre the Holland I, which is comparable to the size of a mini-van, through the water, and use its arms and clasps, which are like hands, to take small samples of corals, sponges and other specimens from extremely hostile parts of the ocean floor where there is no natural light and tremendous ocean pressure.”
By analysing past research relating to sponges and corals, Dr Allcock explained that her team “are able to see that some species are better target groups than others in having antimicrobial or anti-cancer properties.
“Based on this information we are building mathematical models to predict the likelihood of any given species yielding a novel natural product, along with developing species distribution maps of corals and sponges on the deep-sea floor, so that we know the best places to go searching.”
When the research team returns from sea, they work with the national marine biodiscovery lab at the Marine Institute. The chemists at NUI Galway extract the chemical compounds from all of the samples of sponges and corals to see if they have drug-like characteristics such as anti-cancer or antimicrobial properties that can be used for novel drugs to combat human illnesses.
“Chemists involved in biodiscovery research only need small quantities of any organism to develop a new drug, because once a suitable compound is identified, it can be synthesised in the lab, which can then be used in drugs to combat human diseases,” said Dr Thomas.
The ROV Holland I provides high definition continuous video footage of the deep seafloor as it is being used to collect samples.
“Going back through footage after the expedition enables us to further analyse the location recording of all the corals and sponges,” said Dr Allcock. “This improves future predictions of where else we might find similar specimens and also allows us to provide data to inform conservation policy so that we make sure that important ‘hotspots’ rich in corals and sponges are preserved.”
Marine Institute chief executive Dr Peter Heffernan was enthusiastic about the mission’s prospects.
“These are exciting times to be a marine researcher as marine scientists around the world have discovered more species in the ocean in the last ten years than ever before, with an average of 2,000 new discoveries each year,” he said.
“In Ireland we are contributing to building on this wealth of valuable information and sharing the best available science and knowledge to inform decisions affecting the Atlantic Ocean.”
This survey is being undertaken as part of a five-year project on ‘Exploiting and conserving deep-sea genetic resources’ at NUI Galway, co-funded by the Science Foundation Ireland and Marine Institute.
The National Marine Biodiscovery Laboratory project brings together six of the country’s leading marine researchers across a range of disciplines from NUI Galway, University of Limerick and University College Cork to study how marine substances might in future be used to make ingredients for cosmetics, pharmaceuticals and functional foods.
#RVCelticExplorer - Pay a visit on board Ireland’s national marine research vessel wherever you are, thanks to a new immersive 360-degree virtual tour of the RV Celtic Explorer courtesy of the Marine Institute.
Conor Purcell writes in New Scientist on the top attractions aboard the busy marine science vessel, including its wet and dry labs, the tech-filled bridge, its sensor-studded drop keel and even the chief scientist’s cabin.
The RV Celtic Explorer most recently returned from its ‘health check’ of the Atlantic Ocean, which suggests a greater penetration of CFCs in the deeper ocean since the late 1990s.
If this tour whets your appetite, you can still pay a virtual visit to Hook Lighthouse among other coastal locations in Ireland.
#ClimateChange - Preliminary results from the recent ‘health check’ of the Atlantic Ocean suggest a greater penetration of manmade chlorofluorocarbons (CFCs) further into the deeper ocean since 20 years ago.
As previously reported on Afloat.ie, an Irish-led international team of marine scientists from six countries set out from Newfoundland on 27 April on board the RV Celtic Explorer, to survey a transect of the Atlantic last measured two decades ago and investigate the impact of climate change on the deep ocean.
Explaining the team’s findings, Dr Evin McGovern of the Marine Institute and principal investigator on the GO-SHIP A02 survey said: “Although these chemicals have been phased out, they remain in the atmosphere and enter the ocean, where over time, they travel to the deep ocean.
“We measure the CFCs to tell the age of the water masses in the deep ocean and this helps us assess the uptake of fossil fuel carbon from the atmosphere and penetration into the deep ocean.”
The survey formed part of the Global Oceans Ship-Based Hydrographic Investigations Programme (GO-SHIP), which carries out systematic and global surveys of select hydrographic sections, through an international consortium of 16 countries and laboratories.
This was the first GO-SHIP survey to involve such a level of collaboration, with scientists from 10 leading universities and research institutes representing six countries.
Canadian Ambassador to Ireland Kevin Vickers visited the RV Celtic Explorer to meet the team in Galway following their arrival on Monday 22 May.
“This survey is a wonderful example of the Galway Statement in action as well as the longstanding collaboration on marine research between Ireland and Canada,” he said.
Marine Institute chief executive Dr Peter Heffernan added that the expedition’s scientists “are contributing to addressing some of the biggest questions for society and our interaction with our planet.”

#MarineScience - An international team of marine scientists from six countries are currently sailing on Ireland’s national research vessel RV Celtic Explorer on a transatlantic voyage to study the impact of climate change on the ocean.
Departing from St John’s in Newfoundland on Thursday 27 April — after launching the miniature yacht Lancer a few days previously — and due to arrive in Galway on 23 May, the Marine Institute-led team of experts are surveying a transect of the Atlantic Ocean last surveyed 20 years ago to investigate carbon dioxide levels in the ocean.
The survey is essential to understand and project how carbon dioxide emissions are accumulated in the oceans and the atmosphere, as well as its effects on the acidification of the ocean.
The survey is part of the Global Oceans Ship-Based Hydrographic Investigations Program (GO-SHIP), which carries out systematic and global surveys of select hydrographic sections, through an international consortium of 16 countries and laboratories.
This is the first GO-SHIP survey to involve this level of collaboration with scientists from ten leading universities and research institutes representing six countries joining the survey.
Marine Institute chief executive Dr Peter Heffernan said: “The Marine Institute is proud to lead this truly international collaboration. This GO-SHIP A02 survey is a very real example of the Galway Statement in action: working together to better understand and increase our knowledge of the Atlantic Ocean and its dynamic systems, and promoting the sustainable management of its resources.”
The Galway Statement, signed at the Marine Institute 24 May 2013, launched the Atlantic Ocean Research Alliance between the EU, Canada and the USA.
The survey is co-ordinated by the Marine Institute and NUI Galway with research partners in Dalhousie University and Fisheries and Oceans, Canada; University of Exeter, United Kingdom; GEOMAR, Germany; Woods Hole Oceanographic Institution and Columbia University, USA; and Aarhus University, Denmark.
“Ship-based surveys are still the only way to collect the best quality measurements of fundamental physical, chemical and biological properties known as Essential Ocean Variables,” said Dr Evin McGovern of the Marine Institute and principal investigator on the GO-SHIP A02 survey.
“Although technology has provided many new methods to collect ocean measurements, there’s really no substitute for going out on the ocean on a research vessel.
“We can use satellite technology to look at certain properties the ocean surface and can deploy autonomous argo floats to take some measurements to depths of 2000, but we need to carry out ocean surveys that can measure to get a complete picture of the chemistry of the ocean at different depths up to 5,000m.
“The transect we are surveying is a really dynamic area of the Atlantic for heat transport and carbon uptake and is hugely important to informing our understanding of our global climate and how the ocean regulates our climate,” added Dr McGovern.
“The Northwest Atlantic is one of the world’s largest sinks of carbon dioxide and despite progress in our understanding there’s still a huge lack of data as it relates to climate change’s impact on the ocean and what that means for the economy and society,” said Brad de Young, a professor of physics and physical oceanography at Memorial University, Newfoundland and an Ocean Frontier Institute researcher.
“Improving our scientific understanding and developing strategic and effective solutions for safe and sustainable ocean development requires sharing of expertise, international co-operation and exchange of data and best practices. And that’s what this voyage is all about,” adds Doug Wallace, Canada Excellence research chair at Dalhousie University.
#Lancer - The Marine Institute has posted video of the successful launch of the unmanned yacht Lancer in the Atlantic this past weekend.
The miniature marine research vessel was released from the RV Celtic Explorer on Saturday 22 April in the middle of the Atlantic, in the hopes of it catching either the Irminger current (to take it north towards Greenland) or the Canary current (to carry it southwards towards Africa).
According to the most recent fix via the online GPS tracker, Lancer indeed appears to be headed north to continue its mission.
As previously reported on Afloat.ie, the boat was seen off from Galway by Méabh Ní Ghionnáin, who found the vessel beached near her home in Connemara last September.
The eight-year-old since met with Kaitlyn Dow, the Connecticut high schooler who launched the vessel as part of a year-long science project studying ocean winds and currents.
