#MarineScience - The Marine Institute’s RV Celtic Voyager returned to Cork Harbour last week after the first of six INFOMAR seabed mapping surveys planned for 2017.

The two-week seabed survey carried out its operations in the Celtic Sea south of the Waterford and Wexford coastlines.

The research team — involving geophysicists, geologists, marine biologists and data processors Kevin Sheehan, David O'Sullivan, Oisin McManus, Nicola O'Brien and Michael Arrigan — were tasked to accurately map the physical, chemical and biological features of the seabed area.

INFOMAR survey operations are conducted by a fleet of research vessels — including the RV Celtic Voyager, which is used for mapping seabed terrain in water depths between 20m and 100m.

The vessels are equipped with advanced mapping technologies including state-of-the-art acoustic sonars, geophysical instrumentation and ground-truthing capabilities, as well as geophysical equipment and precise satellite positioning.

“This helps to ensure data collection is of the highest possible quality across a wide range of water depths, conditions and environments, providing us with full coverage mapping of the shape and type of the seabed below,” says David O'Sullivan.

The INFOMAR survey around Ireland is one of the largest civilian seabed mapping projects in the world and aims to gather high resolution seabed data that contributes to the sustainable development of Ireland's marine resource.

As an island nation, Ireland is responsible for the sustainable management of its marine resources and it is important that accurate seabed maps are created to enable effective governance.

“Gathering up-to-date information about our ocean is cognisant of ensuring we have the best available science and knowledge to inform decisions affecting our ocean, particularly in relation to fisheries management and the development of ocean energy,” added O’Sullivan.

The INtegrated Mapping FOr the Sustainable Development of Ireland's MArine Resource (INFOMAR) programme is a joint venture between the Geological Survey of Ireland and the Marine Institute, funded by the Department of Communications, Climate Action and Environment.

#SeabedMapping - The Atlantic Ocean Research Alliance's fifth transatlantic seabed mapping survey launched last Friday 22 July from eastern Canada.

Sailing on the Canadian Coast Guard Ship Louis S St-Laurent, the team will map the seafloor across the North Atlantic between Halifax in Nova Scotia and Tromso in Norway till next Tuesday 2 August.

The marine science team led by Paola Travaglini of Fisheries and Oceans Canada's Hydrographic Service are using state-of-the-art deep-water multibeam sonar technology to survey the seabed and study the physical characteristics of the seafloor, as well as other oceanographic data such as temperature and salinity, to better understand little-known areas of the North Atlantic and build on the work done last summer.

These surveys support the Galway Statement on Atlantic Ocean Co-operation, the goals of which are to join resources of its three signatories to better understand the North Atlantic, to promote sustainable management of its resources, and to promote citizens' understanding of the Atlantic through ocean literacy.

Participants in the survey include Fisheries and Oceans Canada's Hydrographic Service, the University of New Hampshire's Center for Coastal and Ocean Mapping Joint Hydrographic Center, and the Fisheries and Marine Institute of Memorial University of Newfoundland.

Students and early-career scientists representing Canada and the United States sailing on board the CCGS Louis S St-Laurent are writing daily blog posts to chronicle the mission. The team comprises:

  • David Thornhill, Hydrographer, Fisheries and Oceans Canada Canadian Hydrographer Service
  • Danielle Roche, Marine Institute of Memorial University of Newfoundland
  • Darren Hiltz, Hydrographer, Fisheries and Oceans Canada Canadian Hydrographer Service
  • Elizabeth Weindren, University of New Hampshire's Center for Coastal and Ocean Mapping Joint Hydrographic Center Fisheries
  • Chris Hemmingway, National Director of UNCLOS, Fisheries and Oceans Canada Canadian Hydrographer Service
  • David Levy, Electrical Technician, Fisheries and Oceans Canada Canadian Hydrographer Service
  • Paola Travaglini, Hydrographer–In–Charge, Fisheries and Oceans Canada Canadian Hydrographer Service

Seabed mapping was one of the ocean research priorities and challenged discussed by the Marine Institute's CEO Dr Peter Heffernan with other heads of European marine science institutes in Ostend earlier this month, which followed a previous consultation that identified such mapping as crucial for managing human activities in our seas.

#MarineScience - Marine Institute chief executive Dr Peter Heffernan was among the heads of European marine science institutes meeting with Karmenu Vella, EU Commissioner for Environment, Maritime Affairs and Fisheries, at the European Marine Board offices in Ostend, Belgium yesterday (Friday 8 July) to discuss ocean research priorities and challenges.

The meeting with Commissioner Vella follows a previous consultation attended by Dr Heffernan in March, which identified ocean observation and seabed mapping as crucial for managing human activities in European seas and across the global ocean.

The European Marine Board said the latest meeting will advance the discussion on ocean observing and seabed mapping in Europe, set within a global context, by identifying critical gaps in our capability, investment needs and potential funding sources for the future.

“Ocean observation and seabed mapping are essential for managing human activities in the ocean," said Dr Heffernan. "With better observation and prediction capability, we can de-risk investment; we can have well informed licensing and regulation for sustainable economic developments; and we can protect ocean ecosystems and the essential services they provide, like food, medicine, and providing half of the oxygen we breathe.”

The Marine Institute CEO added: “Ireland has much to contribute to these consultations as we have significant seabed mapping expertise through INFOMAR, the national seabed mapping programme led by the Geological Survey of Ireland and the Marine Institute.

"And we are developing key ocean observation and marine research infrastructure in Ireland to advance our understanding of the ocean and to underpin innovation in the ocean."

Mapping, observing and predicting changes in the ocean were the focus of discussion at the Our Ocean Wealth conference in Galway last week, at which Ireland’s first ocean observatory was officially launched.

The meeting with Commissioner Vella in Ostend marks the second in a series and is an important platform for the ocean research community to communicate directly with the commissioner on ocean research issues.

#MarineScience - Three Transition Year students recently completed placements hosted by INFOMAR at the Marine Institute.

Jack Lillis, Aoife Muldoon and Emily Egan learned how seabed mapping can improve safety at sea, how it relates to the fishing industry, and how it can help the development of sectors like ocean energy.

Each student spent a week visiting the various Marine Institute facilities and learning about the different activities of the institute.

At the end of their experience, each created a 'story map' and PowerPoint presentation to show what they achieved during their placements.

"We really enjoyed our week at the Marine Institute and we now know a lot more about what a career in marine science really means," said Muldoon and Egan, from St Brigid's Vocational School in Loughrea. "It's a hugely interesting area of science that we don't learn about in school.

"We especially enjoyed our visit to the Celtic Explorer, seeing the multibeam system, learning about seabed mapping and how this information improves the admiralty charts so that vessels like the Celtic Explorer can safely visit ports. We also learnt about how seabed mapping relates to the fishing industry and helps sectors like ccean energy, this was of particular interest to us.

"We would like to thank Vera and all the Advanced Mapping Services and Marine Institute staff for teaching us so much about seabed mapping, fisheries, the laboratories and how all the different areas interlink. We now have a much better idea of what subjects to pick for the Leaving Cert."

Lillis, of Gort Community School, also had "a fantastic week, all the areas I worked in were really enjoyable. I was particularly interested with the laboratory work. Everybody knew what they were talking about and nobody shied away from any questions in fact they encouraged them. Everybody had something lined up for me to do so I was kept really busy, which was great.

"Overall I really enjoyed my week in the Marine Institute and I'm a glad I chose it for my first week of work experience. It was both a good way to see a working environment but also has encouraged me to pursue a career in marine related chemistry. Thanks so much to Tommy, Vera, the Advanced Mapping Services team and staff at the Marine Institute for taking time out of their busy day to facilitate me."


The Marine Institute will run its Transition Year course placements on a pilot basis at the end of April for up to 20 students.

Ireland's offshore islands

Around 30 of Ireland's offshore islands are inhabited and hold a wealth of cultural heritage.

A central Government objective is to ensure that sustainable vibrant communities continue to live on the islands.

Irish offshore islands FAQs

Technically, it is Ireland itself, as the third largest island in Europe.

Ireland is surrounded by approximately 80 islands of significant size, of which only about 20 are inhabited.

Achill island is the largest of the Irish isles with a coastline of almost 80 miles and has a population of 2,569.

The smallest inhabited offshore island is Inishfree, off Donegal.

The total voting population in the Republic's inhabited islands is just over 2,600 people, according to the Department of Housing.

Starting with west Cork, and giving voting register numbers as of 2020, here you go - Bere island (177), Cape Clear island (131),Dursey island (6), Hare island (29), Whiddy island (26), Long island, Schull (16), Sherkin island (95). The Galway islands are Inis Mór (675), Inis Meáin (148), Inis Oírr (210), Inishbofin (183). The Donegal islands are Arranmore (513), Gola (30), Inishboffin (63), Inishfree (4), Tory (140). The Mayo islands, apart from Achill which is connected by a bridge, are Clare island (116), Inishbiggle (25) and Inishturk (52).

No, the Gaeltacht islands are the Donegal islands, three of the four Galway islands (Inishbofin, like Clifden, is English-speaking primarily), and Cape Clear or Oileán Chléire in west Cork.

Lack of a pier was one of the main factors in the evacuation of a number of islands, the best known being the Blasket islands off Kerry, which were evacuated in November 1953. There are now three cottages available to rent on the Great Blasket island.

In the early 20th century, scholars visited the Great Blasket to learn Irish and to collect folklore and they encouraged the islanders to record their life stories in their native tongue. The three best known island books are An tOileánach (The Islandman) by Tomás Ó Criomhthain, Peig by Peig Sayers, and Fiche Blian ag Fás (Twenty Years A-Growing) by Muiris Ó Súilleabháin. Former taoiseach Charles J Haughey also kept a residence on his island, Inishvickillaune, which is one of the smaller and less accessible Blasket islands.

Charles J Haughey, as above, or late Beatle musician, John Lennon. Lennon bought Dorinish island in Clew Bay, south Mayo, in 1967 for a reported £1,700 sterling. Vendor was Westport Harbour Board which had used it for marine pilots. Lennon reportedly planned to spend his retirement there, and The Guardian newspaper quoted local estate agent Andrew Crowley as saying he was "besotted with the place by all accounts". He did lodge a planning application for a house, but never built on the 19 acres. He offered it to Sid Rawle, founder of the Digger Action Movement and known as the "King of the Hippies". Rawle and 30 others lived there until 1972 when their tents were burned by an oil lamp. Lennon and Yoko Ono visited it once more before his death in 1980. Ono sold the island for £30,000 in 1984, and it is widely reported that she donated the proceeds of the sale to an Irish orphanage

 

Yes, Rathlin island, off Co Antrim's Causeway Coast, is Ireland's most northerly inhabited island. As a special area of conservation, it is home to tens of thousands of sea birds, including puffins, kittiwakes, razorbills and guillemots. It is known for its Rathlin golden hare. It is almost famous for the fact that Robert the Bruce, King of Scots, retreated after being defeated by the English at Perth and hid in a sea cave where he was so inspired by a spider's tenacity that he returned to defeat his enemy.

No. The Aran islands have a regular ferry and plane service, with ferries from Ros-a-Mhíl, south Connemara all year round and from Doolin, Co Clare in the tourist season. The plane service flies from Indreabhán to all three islands. Inishbofin is connected by ferry from Cleggan, Co Galway, while Clare island and Inishturk are connected from Roonagh pier, outside Louisburgh. The Donegal islands of Arranmore and Tory island also have ferry services, as has Bere island, Cape Clear and Sherkin off Cork. How are the island transport services financed? The Government subsidises transport services to and from the islands. The Irish Coast Guard carries out medical evacuations, as to the RNLI lifeboats. Former Fianna Fáíl minister Éamon Ó Cuív is widely credited with improving transport services to and from offshore islands, earning his department the nickname "Craggy island".

Craggy Island is an bleak, isolated community located of the west coast, inhabited by Irish, a Chinese community and one Maori. Three priests and housekeeper Mrs Doyle live in a parochial house There is a pub, a very small golf course, a McDonald's fast food restaurant and a Chinatown... Actually, that is all fiction. Craggy island is a figment of the imagination of the Father Ted series writers Graham Linehan and Arthur Mathews, for the highly successful Channel 4 television series, and the Georgian style parochial house on the "island" is actually Glenquin House in Co Clare.

Yes, that is of the Plassey, a freighter which was washed up on Inis Oírr in bad weather in 1960.

There are some small privately owned islands,and islands like Inishlyre in Co Mayo with only a small number of residents providing their own transport. Several Connemara islands such as Turbot and Inishturk South have a growing summer population, with some residents extending their stay during Covid-19. Turbot island off Eyrephort is one such example – the island, which was first spotted by Alcock and Brown as they approached Ireland during their epic transatlantic flight in 1919, was evacuated in 1978, four years after three of its fishermen drowned on the way home from watching an All Ireland final in Clifden. However, it is slowly being repopulated

Responsibility for the islands was taking over by the Department of Rural and Community Development . It was previously with the Gaeltacht section in the Department of Media, Tourism, Arts, Culture, Sport and the Gaeltacht.

It is a periodic bone of contention, as Ireland does not have the same approach to its islands as Norway, which believes in right of access. However, many improvements were made during Fianna Fáíl Galway West TD Éamon Ó Cuív's time as minister. The Irish Island Federation, Comdháil Oileáin na hÉireann, represents island issues at national and international level.

The 12 offshore islands with registered voters have long argued that having to cast their vote early puts them at a disadvantage – especially as improved transport links mean that ballot boxes can be transported to the mainland in most weather conditions, bar the winter months. Legislation allowing them to vote on the same day as the rest of the State wasn't passed in time for the February 2020 general election.

Yes, but check tide tables ! Omey island off north Connemara is accessible at low tide and also runs a summer race meeting on the strand. In Sligo, 14 pillars mark the way to Coney island – one of several islands bearing this name off the Irish coast.

Cape Clear or Oileán Chléire is the country's most southerly inhabited island, eight miles off the west Cork coast, and within sight of the Fastnet Rock lighthouse, also known as the "teardrop of Ireland".
Skellig Michael off the Kerry coast, which has a monastic site dating from the 6th century. It is accessible by boat – prebooking essential – from Portmagee, Co Kerry. However, due to Covid-19 restrictions, it was not open to visitors in 2020.
All islands have bird life, but puffins and gannets and kittiwakes are synonymous with Skellig Michael and Little Skellig. Rathlin island off Antrim and Cape Clear off west Cork have bird observatories. The Saltee islands off the Wexford coast are privately owned by the O'Neill family, but day visitors are permitted access to the Great Saltee during certain hours. The Saltees have gannets, gulls, puffins and Manx shearwaters.
Vikings used Dublin as a European slaving capital, and one of their bases was on Dalkey island, which can be viewed from Killiney's Vico road. Boat trips available from Coliemore harbour in Dalkey. Birdwatch Ireland has set up nestboxes here for roseate terns. Keep an eye out also for feral goats.
Plenty! There are regular boat trips in summer to Inchagoill island on Lough Corrib, while the best known Irish inshore island might be the lake isle of Innisfree on Sligo's Lough Gill, immortalised by WB Yeats in his poem of the same name. Roscommon's Lough Key has several islands, the most prominent being the privately-owned Castle Island. Trinity island is more accessible to the public - it was once occupied by Cistercian monks from Boyle Abbey.
