Ireland should have 75 per cent of its land territory mapped this year, according to the Geological Survey of Ireland (GSI).

A low-flying aircraft will gather geophysical date over counties Laois, Tipperary, Kilkenny and Waterford, and neighbouring parts of Offaly, Cork, Carlow and Kildare from September until the end of the year, weather permitting, the GSI says.

Based at Waterford airport, the survey plane will be flying at 60 metres over rural areas – about eight times the height of a two-storey house – and 240 metres over urban areas in the coming months, as approved by the Irish Aviation Authority.

The GSI is already involved in seabed mapping with the Marine Institute under the INFOMAR programme, and the Tellus Survey has been conducted on land over the last nine years.

Tellus collects geochemical and geophysical data on rocks, soil and water across Ireland. It involves airborne physical surveying using a low-flying aircraft, and ground-based geochemical surveying of soil, stream water and stream sediment.

It is currently funded under Project2040 - the National Development Plan – by the Department of Communications, Climate Action and Environment.

The department says it has “the potential to deliver positive economic, environmental and agricultural benefits by helping to assist in local environment understanding, soil management, and natural resource potential for these counties”.

Tellus project manager and senior geologist Dr James Hodgson describes it as “an important national project, providing valuable insights into the geological makeup of Ireland”.

“The data collected from the Tellus Survey helps us to sustainably manage our environment and natural resources as well as protecting public health,” he said.

The survey aircraft is a white, twin-propeller plane (as pictured), which is easily identified by its red tail and black stripe as well as the word ‘SURVEY’ and registration number C-GSGF written across both sides of the plane.

Data collected throughout the Tellus project is published and made freely available to all on the Tellus website (www.tellus.ie).

When Dr Kathy Sullivan (68) climbed out of a tiny submersible which had returned from the bottom of the Mariana Trench, none of the subsequent headlines were quite as clever as that “most vertical girl in the world” slogan coined by several of her friends.

It inspired a badge which she now wears -the first female US astronaut to walk in space and to reach the deepest known point of the world’s oceans has a sharp sense of humour. Some might say with her Irish lineage that she’d have to have – she has cousins on beautiful Beara peninsula.

Former Marine Institute chief executive Dr Peter Heffernan wisely developed that link through initiatives like the Atlantic Ocean Research Alliance when Dr Sullivan was US Under Secretary of Commerce for Oceans and Atmosphere and National Oceanic and Atmospheric Association Administrator (NOAA).

Dr Sullivan - an oceanographer and geologist - joins that panoply of individuals with Irish connections who have distinguished themselves over many centuries in the marine sphere, be it in fishing or trade, or in foreign navies, in exploration, or in technology and innovation.

The lives of many of these mostly male marine pioneers - from St Brendan to submarine designer John Philip Holland and explorers Sir Ernest Shackleton and Edward Bransfield - have been documented by late maritime historian Dr John de Courcy Ireland among others. He was often asked by colleagues at international conferences to explain why so many Irish mariners of note had to go abroad to make their name.

These academics were curious to know why there was not much more lasting “Viking influence” in Irish socio-economic activity, given that Ireland’s coastal state population was not dissimilar in size to that of Norway. The “real map of Ireland” is at least ten times the land size - as that clever Marine Institute postcard image depicts - and our Continental Shelf position on a northerly latitude is tempered by the influence of the Gulf Stream

The impact of colonisation, including deliberate efforts to suppress the Irish fishing fleet when it became too competitive, were among reasons given by Dr de Courcy Ireland during a debate on this question at a conference on “Ireland the Sea”. It was hosted by the Merriman Summer School and Bord Iascaigh Mhara in Co Clare back in 1983.

I came across the paperback record of that debate, and it was welcome distraction during a brief “Covid-19 lockdown” office tidy. Conference participant and founding Irish Skipper editor Arthur Reynolds pointed to the uneconomic reality of 900 different landing points around the coast. The fertility of this island’s soil always made agriculture a more attractive bet, he said.

Labour Party politician Justin Keating, a vet and RTÉ Head of Agricultural Programmes, posed a more complex answer. During his time as industry and commerce minister almost a decade earlier, he had attempted to set up a “Statoil” model for hydrocarbon development here. He noted that the sea provided this State with “almost an embarrassment of riches, and a superb national challenge”.

“The fact that this potential had not been realised was not due to “genetics” or “laziness”, but due in part to economics and the “horrendously expensive” costs of certain maritime development, Keating said. However, there was also a confidence factor, he argued; we were only beginning to recover from a “profound culture shock” which was “not unique to us”.

The colonial experience had touched “everywhere in the world where people were defeated by newer and superior technology, from South-East Asia to the homelands of the North American Indians,” Keating said. He outlined one First Nation response to this shock - the “ghost dance”, and suggested the Irish version of this was our “fascination with words and music.... based on their use in a magic sense, for altering consciousness and for making reality go away....”.

Magic being illusionary, the only possible “national therapy” was development of our marine potential, in his view. Without mobilisation of capital – which had fled these shores over previous centuries – we would not “mobilise technology”, he said.

That same year, a marine management system which has had devastating results for coastal states like this one was rubberstamped. Just two EU states – Ireland and Denmark - had a surplus of fish at the time of Common Fisheries Policy (CFP) formulation.

The CFP is subject to ten-yearly reviews, which now place much greater emphasis on sustainability. Brexit creates a really serious challenge, as industry organisations have outlined, yet there seems to be a reluctance here to seek a more equitable revision of the policy, based on proximity to a resource.

As the late Castletownbere fishermen and industry leader Donal O’Driscoll pointed out, the initial deal struck in favour of agricultural benefits and structural funds was never intended by our EU masters to be “cast in stone”.

EU directives on the environment have had a more positive influence, though sometimes failing to protect communities from the pressures of the market. A template for democratic planning published by the British Institution of Civil Engineers four years ago cited this State’s handling of the Corrib gas project as an example of “how not to undertake a development”.

The methodology known as Global Risk and Strategic Assessment Planning (GRASP) developed by British chartered surveyor Michael Ocock, organisational psychologist Prof Agi Oldfield and colleagues aims to avoid selective consultation or a domination of debates by “rogue stakeholders” and the “space shuttle syndrome” identified in large scale projects which have taken a wrong turn. Scottish islanders have also taught us that sustainability is not about ticking consultation boxes, but about genuine stakeholder engagement and community return.

Growing of seaweedGrowing of seaweed

Like the tide coming in and out twice a day, the sea still throws up endless opportunities for change – seaweed culture as one example, which the late British scientist Dr Eric Edwards once forecast would be far more lucrative for Ireland than salmon farming. Fascinating work by the Bantry Marine Research Station in west Cork is exploring how a type of red seaweed could also reduce methane emissions in cattle – a valuable case, if realised, of “blue meets green”.

That active Atlantic system which could turn Ireland into a “Green gulf” of renewable energy, in the words of one developer, could fuel home energy needs and bulk hydrogen exports. The 30-year strategy drawn up by the Eirwind consortium involving University College, Cork researchers Dr Val Cummins (now gone into private practice) and Dr Jimmy Murphy and industry cites the importance of prioritising the long-awaited marine planning framework and supporting legislation.

The reports by NUI Galway’s Socio-Economic Marine Research Unit which inform the government’s Harnessing Our Ocean Wealth strategy show a positive trend. It recently reported on the opportunities which coastal tourism could offer during this pandemic.

coastal tourism studyTotal expenditure by domestic tourists in coastal areas was estimated to be €698 million in 2018, which represents 35% of the total expenditure by domestic tourists that year, a new study says.

Complementing the research in third-level institutions and the efforts of the Marine Institute and BIM, there are also a plethora of individuals and non-governmental organisations who have helped to raise awareness of our maritime heritage and of our potential on the Atlantic margin.

Like Dr Sullivan, there are many women involved in the forefront of marine research, development, innovation, along with master mariners, harbourmasters, sailors like Olympic medallist Annalise Murphy and offshore yachtswoman Joan Mulloy. Yvonne Shields O’Connor, formerly of the Marine Institute, is chief executive of the Commissioners of Irish Lights, and Ireland’s first female master marine Capt Sinead Reen is in a senior role at the National Maritime College of Ireland.

And Irish people no longer have to leave to have an impact in that big blue field. Marine Institute chief executive Dr Paul Connolly has been at the helm of the prestigious International Council for the Exploration of the Seas (ICES), and his predecessor, Dr Heffernan, is one of 15 experts on the European Commission’s Mission Board for Healthy Oceans, Seas, Coastal and Inland Waters. And the unthinkable happened in 2015 when a former Naval Service flag officer, now Vice-Admiral Mark Mellett, became head of the Defence Forces.

A global pandemic can focus attention on the potential of the ocean environment and the rich waters around this island - as a vital source of protein, new medical treatments and a source of renewable energy. However, a pandemic might also distract attention from its fragility, and the fact that man-made rubbish has reached the remote Mariana Trench and microplastics are poisoning the deepest ocean creatures.

“We have taken for granted the fact that we have been fortunate to live in the Goldilocks zone – that sweet spot in relation to the Sun,” Dr Sullivan told me in a recent interview.

Ireland is in the sweetest “Goldilocks zone” when it comes to marine resources. We must be ready to manage that good fortune sensitively, and for both communities and individuals, when the gold rush comes.

US astronaut and oceanographer Dr Kathryn Sullivan has compared the current global situation to being in the midst of a severe storm on a sailing boat in mid-ocean.

In an interview with The Sunday Times, Dr Sullivan, who has Irish roots, said that although she was an optimist, it was “the most uncertain time I have witnessed in my lifetime”.

“You couldn’t even think of putting a sail back up, let alone trimming it, or trying to steer..only to ride it out as best one can...” she said.

“ It’s a bit like watching the circus performer twirling plates on the end of a stick, relying on gyroscopic forces – but if the twirling slows down any, the plates start to wobble like crazy,” she said

A global pandemic can focus attention on the potential of the ocean environment as a vital source of protein and new medical treatments, she notes.

However, she cautions that the oceans are under considerable pressure, thanks to “we two-footed critters” allowing rubbish to reach the very bottom of the remote Mariana Trench and microplastics to poison the deepest ocean creatures.

“So there is no part of this planet that is disconnected,” she says.

Dr Sullivan, who developed close links with the Marine Institute here during her term as US Under Secretary of Commerce for Oceans and Atmosphere and National Oceanic and Atmospheric Association Administrator (NOAA), has been invited by the institute to give a public “virtual” interview.

The Most Vertical Girl in the World. The woman who's made history in sea and space; The astronaut, oceanographer, explorer, author and the first person to ever experience travelling to both deep space and the oceans deep.

Kathy Sullivan is already in the history books as the first American woman to walk in space in 1984, the 68-year-old found herself making history again just last month.

On June 6, the oceanographer and former NASA astronaut became the first woman to reach Challenger Deep, the deepest known location in the ocean.

The 35,810-foot dive, which was undertaken on the DSV Limiting Factor and co-piloted by Victor Vescovo, now makes Sullivan the first person to both walk-in space and descend to the deepest point in the ocean.

The two missions, total opposites in the minds of many, for Sullivan, come from her one simple desire: to understand the world around her as much as possible.

Join Kathy Sullivan in an exclusive Irish Interview with broadcaster Pat Kenny where she will share her remarkable history-making story, offering unique insights into her exploration at the extreme frontiers, recalling the experiences of walking in space and charting oceans.

You can tune into the Kathy Sullivan in Conversation Livestream on any one of the Marine Institute's social media channels on Thursday, 23 July at 2 pm IST  and read Lorna Siggins' interview with Sullivan in The Sunday Times, this week, July 19th.

The Marine Institute says that its fish health inspection and monitoring activities in 2018 and 2019 indicate that there is a high level of compliance with EU and national legislation, and as a result, Ireland continues to maintain its high health status for aquatic animals.

As the Competent Authority, the Marine Institute is legally responsible for implementing EU and national regulation relating to aquatic animal health in Ireland. In this role, the Marine Institute aims to ensure that the existing high health status of aquatic animals in Ireland is maintained.

A new report published by the Marine Institute's Fish Health Unit (FHU) outlines the activities of the FHU in 2018 and 2019 and highlights that there was a high level of compliance with regulatory fish health requirements. A total of 384 health surveillance inspections of aquaculture production businesses were undertaken during this period, and 98% of the 384 sites inspected had no compliance issues or compliance issues that were categorised as minor.

Bill Doré, Manager of the Marine Institute's Fish Health Unit said, "As the Competent Authority in Ireland, the Marine Institute makes an important contribution to preventing and controlling aquatic animal diseases. By working closely with other state agencies to implement aquatic animal health regulations, Ireland is able to maintain its high health status for aquatic animals."

All Aquaculture Production Businesses in Ireland, such as finfish farms, shellfish farms, and put and take fisheries, must obtain a Fish Health Authorisation from the Marine Institute. To receive a Fish Health Authorisation, Aquaculture Production Businesses submit a Fish Health Management Plan for approval. This plan addresses how aquatic animal health will be maintained, and how diseases are controlled, as well as the mandatory conditions for record keeping and reporting to the Competent Authority.

The Marine Institute's Fish Health Unit, working with colleagues in the Department of Agriculture, food and the Marine veterinary services conducts regular health surveillance of fish and shellfish farms in Ireland, and is responsible for regulating the movement of aquatic animals within Ireland and during import or export to and from the state. In the 2018 and 2019 reporting period, over 3,000 movements of aquatic animals were approved.

The Fish Health Unit also hosts the National Reference Laboratories for finfish, mollusc and crustacean health for Ireland. The laboratories undertake testing and applied research to support fish health activities in Ireland. During the reporting period, the laboratories analysed over 1,500 shellfish and 5,000 fish for diagnostic, statutory and research purposes.

Coastal Communities are the focus this week on the Marine Institute’s Oceans of Learning series. The Marine Institute and partners are celebrating our world’s shared ocean and our connection to the sea in a 10-week series, sharing news and offering online interactive activities, videos and downloadable resources on a new marine topic each week

A series of watercolour illustrations and interviews have captured the importance of the ocean to coastal communities in Ireland and Wales as part of BlueFish, an EU-funded project. Through engaging with coastal communities using art, BlueFish links knowledge and understanding of the marine resources and the potential impacts of climate change on the Irish and Celtic Sea ecosystem

"Without the ocean, we wouldn't have a living: it's our only source of income in this rural part of Ireland. Climate change is definitely happening: growth periods are longer than they ever were. But higher water temperatures and higher rainfall could be catastrophic for our business," according to Oyster and mussel fishermen, Cromane, Co. Kerry.

The marine science research project BlueFish is a partnership between six organisations in Ireland and Wales including the Marine Institute, University College Cork, Bord Iascaigh Mhara, Bangor University, Aberystwyth University and Swansea University.

Urban sketcher Róisín Curé and a scientist from the Marine Institute visited coastal communities in Ireland and Wales. Róisín created watercolour illustrations showing the people whose livelihoods are dependent on the ocean and who have a profound and immediate interest in the effects of climate change. Also interviewed were fishermen, restaurateurs, shellfish producers, operators in the tourism sector and seafarers to gather an understanding about how they benefit from the ocean and their thoughts on climate change. The results of the interviews and art through watercolour illustrations created an accessible way for the public to understand the importance the ocean has on livelihoods in coastal communities.

By bringing artists and marine scientists together and working closely with project partners and coastal communities, the Marine Institute has developed a structured portfolio of artwork that is intended to promote a better understanding of the impacts of climate change on ecosystem goods and services; to demonstrate how climate change may impact these; and to highlight the wider societal benefits of healthy ecosystems in Irish and Welsh coastal communities that border the Irish and Celtic Sea(s). The artwork produced as part of the BlueFish project can be viewed in this video.

Dr Paul Connolly, CEO of the Marine Institute explained that "a central part of the project was listening to people living and working in coastal communities, and gathering their opinions about climate change and learning about how it might affect their livelihoods. This was a unique opportunity to talk directly to coastal communities and capture their perspectives through art," Dr Connolly said.

By engaging with people and industries dependant on the sea, the information gathered highlighted how they benefit from the ocean, their thoughts on climate change, and particularly how it was going to affect their lives and businesses.

"Many of the stories reaffirmed the importance of the age-old relationship between people and the sea, noting that the sea is the life-blood which sustains these communities. The general consensus in both Ireland and Wales coastal communities was that climate change is happening. There was an acknowledgement and a realisation amongst the people interviewed that there was a real looming threat to their livelihoods," said Dr Connolly.

Many people commented on how they were seeing changes to their climate in their local communications. A local businessman from the Isle of Anglesey commented, 'in the 38 years I've been working here, the road would have flooded twice a year. Now it floods much more often.'

The Marine Institute’s Oceans of Learning series this week highlights Ireland’s Coastal Communities. Oceans of Learning offers videos, interactive activities and downloadable resources on our coasts and seashore. Commissioners of Irish Lights offers videos on the work they do to ensure safe navigation around our coast and a colouring book on the Great Lighthouses of Ireland. Find out more about Údarás na Gaeltachta and marine businesses in coastal communities through a series of videos. Discover the animals, seaweeds, plants and creatures along the seashore with the Explorers Education Programme’s Seashore Guide Work Book, and explore the habitats of Galway Bay with activities from Galway City Museum. There are also videos on the Marine Institute's shellfish safety programme and our coastal economy, posters and colouring activities about the marine life found along Ireland's coast.

Scientists in West Cork are reporting significant results in use of a type of red seaweed to reduce methane emissions in cattle.

Cuts of between 40 and 98 per cent in emissions have already been achieved in trials in the US, Australia and New Zealand, Bantry Marine Research Station has told The Farmers’ Journal and The Irish Independent.

The West Cork research station, which is now owned by veterinary pharmaceuticals company Bimeda, has been testing effectiveness of red seaweed species Asparagopsis armata in animal feed here.

Canadian scientist Dr Rob Kinley, who pioneered research on its use with the Australian Common Scientific and Industrial Research Organisation (CSIRO), has been collaborating with the Bantry station, managed by David O’Neill.

Asparagopsis armata which was discovered in Irish waters about 60 years ago and cultivated in the late 1990s in Ard Bay, Co Galway by research company Taighde Mara Teo, would have to be farmed here to meet sufficient quantities, O’Neill points out.

Asparagopsis armata was discovered in Irish waters about 60 years ago

He estimates animals fed with the constituent here could reduce emissions by 50 to 60 per cent.

The marine research company is co-operating with Udaras na Gaeltachta and Teagasc, and hopes to raise funds for more animal trials.

Údaras na Gaeltachta director of enterprise, employment and property Dr Mark White said there could be a double benefit for both farmers and climate change targets if the Bantry station’s work on the red seaweed additive does prove fruitful.

Teagasc principal research officer Prof Sinead Waters, who is also adjunct professor at the Ryan Institute, NUI Galway, said that while initial results from Australia and elsewhere are positive, “further research is warranted”.

Prof Waters and Teagasc colleague Dr Maria Hayes, are involved in two projects testing various feed additives to reduce methane - “Meth-Abate” funded by the Department of Agriculture, Food and Marine, and “SeaSolutions” an EU- funded project with other Irish, EU and Canadian partners.

“There are a lot of caveats, such as bromoform, a compound within seaweed which is a known to reduce methane emissions but is also a known carcinogen. We need to ensure that if seaweed is fed to ruminants that no bromoform or other residues appear in the end meat and milk products,” Prof Waters said.

Celebrating World Oceans Day and this year’s theme of ‘Innovation for a Sustainable Ocean’ is the focus of the Marine Institute’s Oceans of Learning series this week.

As Afloat reported earlier, the Institute and partners celebrate our world’s shared ocean and our connection to the sea throughout the 10-week series, sharing news and offering online interactive activities, videos and downloadable resources on a new marine topic each week.

World Oceans Day (#worldoceansday) takes place on Monday 8 June and connects people globally in celebrating the ocean, its importance to our lives and focusing on how each of us can protect the ocean, no matter where we live. This year, the day particularly focuses on the role that innovation has in making our interactions with the ocean sustainable.

The latest report on the ocean economy from the Organisation for Economic Co-operation and Development (OECD) emphasises the growing importance of science and technologies in improving the sustainable economic development of our seas and oceans. Marine ecosystems sit at the heart of many of the world’s global challenges: food, health and wellbeing, new sources of clean energy, climate change, job creation and inclusive growth.

We need to safeguard and improve the health of marine ecosystems to support our ever-growing use of marine resources. As the challenges to our ocean continue to grow, so too does our need for innovative solutions to address them.

Minister for Agriculture, Food and the Marine, Michael Creed, stated, “Ensuring a sustainable future for our oceans will require stakeholders to focus on innovative mechanisms for addressing both current and future challenges. The Oceans of Learning campaign – One Shared Ocean, One Shared Future - will continue to showcase positive developments across the marine sector in recent years and examples of innovation in action as we approach and celebrate World Oceans Day 2020.”

Dr Paul Connolly, CEO of the Marine Institute, said, “Our ocean is our greatest natural resource and we see that most directly in Ireland with the vital importance that the Atlantic Ocean plays in our daily lives – from facilitating our trade through shipping to influencing the weather and providing seafood to support a healthy diet.

“This year’s theme for World Oceans Day is especially relevant in the lead-up to the UN Decade of Ocean Science for Sustainable Development, which will run from 2021 to 2030, and is born out of the recognition that much more needs to be done to create improved conditions for the sustainable development of our oceans, seas and coasts and to reverse the decline in ocean health.”

Oceans of Learning is marking World Oceans Day by featuring projects that use innovative ways to learn more about our oceans and feed back information that is helping to make a positive impact on our daily lives.

With the aim of driving innovation in the marine sector and accelerating renewable energy breakthroughs, the Marine Institute has provided funding to a number of marine enterprises in Ireland. For example, seven renewable energy projects are benefitting from a significant funding injection following investment by the Institute’s industry-led awards, launched in 2018. From research on the impact of floating platform technology, to subsea micro piling to hybrid solar and wind energy devices, the commercial and scientific potential of these new innovations are very exciting.

Exceedence and Technology from Ideas (TFI) are developing an offshore hybrid system, which will benefit the aquaculture sector. Offshore aquaculture farms, where it is too far to reach with electricity cables from shore, currently use diesel as their main source of energy to operate feed barges and other equipment. This brings concerns of ever growing emissions and the climate impact but also increased risk of oil spillages when transporting diesel to the feed barges.

Energy from the waves is a very attractive alternative energy source. TFI and Exceedence are developing an offshore hybrid power system that harnesses the natural power of the waves by converting the motion of the fish cage into electricity.

Ray Alcorn, CEO at Exceedence said, “Our full hybrid off grid power system technology produces clean blue electricity by harnessing the power of the waves, mitigating the fossil fuel requirements on fish cages, which in turn reduces the overall carbon footprint, improving both environmental and climate impacts.”

Ocean data service company XOCEAN, also received funding from the Institute’s industry-led awards to transform marine monitoring and data collection. The company uses innovative robotics, particularly unmanned surface vessels, to monitor and collect fisheries data at sea. As fish are highly mobile, this brings limitations in using single sonar surveys. XOCEAN is researching and developing a cost-effective way of deploying and using unmanned technology with multiple sonar devices simultaneously to survey for fish in an area, in what’s known as a ‘swarm’ formation.

“XOCEAN is delighted to be working with the Marine Institute on this important project,” said James Ives, CEO of XOCEAN. “Sustainability of fish stocks is of critical importance and management of this depends on high quality data. Unmanned systems, such as XOCEAN’s XO-450 USV have an important role to play in delivering safe, high quality and ultra-low carbon ocean data.”

World Oceans Day encourages us to make a difference in our life, in our community, and in our world, by taking action to protect our ocean – for present and future generations. By working together and thinking creatively, we can achieve a healthier ocean that will provide for the billions of humans, plants and animals which depend on it every day.

Celebrating the United Nations International Day for biological diversity (22nd May), the Marine Institute's Explorers Education Programme has published My Explorers Seashore Guide Work Book with support from the National Biodiversity Data Centre's Explore Your Shore! project, to raise awareness about our seashore's marine biodiversity in Ireland.

Congratulating the Explorers Education Programme on their collaboration with The Explore Your Shore! project, funded by the EPA, Dr Paul Connolly, CEO Marine Institute said, "The United Nations International Day for biological diversity promotes 'our solutions are in nature' and places an emphasises on solidarity and working together to build a future in harmony with nature. We welcome, therefore, the support of citizen science projects such as this with primary school children."

Leading into the UN Decade of Ocean Science for Sustainable Development and the UN Decade on Ecosystem Restoration (2021-2030), there is an emphasis on a global movement to transform ocean science for a better world. "Taking the time to enjoy and learn more about our seashore, at a local level provides an important opportunity to examine our relationship with our abundant marine environment, creating ocean champions of the future." Dr Connolly added.

"We are delighted to collaborate with the Explore Your Shore! project team and publish an early online version of My Explorers Seashore Guide Work Book that is free to download on www.explorers.ie. The workbook provides a range of activities encouraging children to explore the shore, take photos, draw and write about their discoveries. It also encourages children to become citizen scientists for the day and load snapshots of the species they find to www.ExploreYourShore.ie to help document marine seashore species in Ireland," said Cushla Dromgool-Regan, author of the book and Explorers Education Strategic Manager, Camden Education Trust.

Ireland has 3,171 km of coastline and there are relatively few records of intertidal and coastal marine species. As an island nation, with over half of Ireland's population living 5km from the ocean, the seashore provides a unique opportunity to learn more about the incredible biodiversity that is on our doorsteps.

"With the Explorers Education Programme reaching over 12,000 children in schools annually, we are delighted to feature in the book that will be used later this year in schools. The book supports our efforts to record and increase our knowledge about the distribution of our intertidal species around the Irish coastline. By releasing this fun resource now, we hope that many more children will get the opportunity to start their seashore exploration through their stay at home learning over the summer months," said David Wall, Citizen Science Officer, National Biodiversity Data Centre.

Teachers taking part in the Explorers Education Programme Seashore Safari modules next term will all receive copies of the books for their students in their class. As an early release, the book is now available online at www.explorers.ie for parents to use at home over the next month before homeschooling breaks up.

Marine Scientists on the RV Celtic Explorer have collected a network of seismometers recording valuable data over the past 19 months in Irish, British and Icelandic waters.

The 18 seismometers had been deployed in 2018 over a 1500 kilometre area from north to south and over 1,000 km of sea from east to west as part of a project run by the Dublin Institute of Advanced Studies (DIAS).

As Afloat previously reported, a “skeleton” team of six scientists and a small crew on the Marine Institute research vessel went to sea last month to retrieve them and returned to Galway this week after three weeks at sea.

Team leader Dr Sergei Lebedev, DIAS seismologist, said the data captured by the seismometers would “shed light on the nature, occurrence, and frequency of earthquakes off our coast, and is fundamental to our understanding of them”.

“The current nature and history of the ocean floor along Ireland's coast is key to our understanding of how the Atlantic evolved and is evolving, and this is important for better understanding both the natural hazards and natural resources offshore," he said.

"For example, slope failures triggered by earthquakes can generate tsunamis in the Irish offshore territory – the data will give us new insights into this hazard,” he said.

The expedition was “time-critical”, as there were fears the data would be lost if the sensors were not retrieved. Physical distancing measures as part of HSE guidelines on the Covid-19 pandemic were in place for the expedition, according to the DIAS team.

"The seismometers have waterproof memory sticks with recordings of earthquakes off the coast of Ireland. To date, these have been poorly understood, but we know they are generally larger than the ones Ireland has onshore. The new data will give us much greater insights into earthquake mechanisms and, also, into the structure of the Earth's interior,” Dr Lebedev said.

"The instruments have made continuous recordings from the last 19 months of the songs of the great baleen whales, including the blue, fin, humpback and North Atlantic right whales. These unique recordings will build our understanding of the migration patterns of the Earth's largest animals and their acoustic environment, known to be crucially important for them,” he said.

Before the seismometers were deployed in 2018, DIAS ran a competition inviting secondary school students to name each one. Suggestions included “The Dude”, “Gráinne”, “Luigi” and “The Loch Ness Mometer”.

During the retrieval expedition, the research team hosted live video links with school classes from St Francis National School in Wicklow, along with St Joseph's College in Tipperary, and a school in Calabria, Italy.

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.”
