The IMTA Impaqt pilot site at Lehanagh Pool, in Connemara
Seafood is a popular and healthy food product in Ireland with the average Irish person consuming about 22kg of fish per year. People recognise the health benefits with fish being low-fat and a good source of omega-3 fats, which are…
Marine science researcher Silvia Blanco with Red seaweed Asparagopsis armata tests at Bantry marine research station, Co Cork, which may help to reduce methane emissions in cattle if added to animal feed
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…
A biodiversity dive
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…
Marine scientist working in a residue lab
The Marine Institute has announced a call for proposals from academic institutions to host Cullen Scholars and provide research training opportunities for scientists in marine and related disciplines leading to the acquisition of a doctorate. The Cullen Scholars will be…
My Explorers Seashore Guide Work Book Published on International Biological Diversity 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…
Ireland Marine Sector Collaborates to Celebrate European Maritime Day Virtually
In recognition of European Maritime Day on 20th May and World Oceans Day on 8th June, the Marine Institute and partners will celebrate our seas, our world’s shared ocean and our connection to the sea through our Oceans of Learning…
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)
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…
To investigate the impact of microplastic exposure, the research team divided hermit crabs between experimental tanks, half containing microplastics while the other half had no plastic
New marine research from Queen’s University Belfast and Liverpool John Moores University reveals how the microplastic pollution crisis is threatening biodiversity. Currently up to 10 per cent of global plastic production ends up in the sea although the understanding of…
These photos from the previous expedition in 2018 show the scientists going out to lay the sensors which they are now heading out to sea to collect
A team of scientists who have been self-isolating like astronauts for the past fortnight set sail from Galway at the weekend on an unusual mission. Six researchers from the Dublin Institute for Advanced Studies (DIAS) and 15 crew on Marine…
Students taking part in the offshore practical portion of the new MSc seabed mapping module
A new Master’s course specialising in remote sensing and the principles of seabed mapping has been successfully delivered by a joint partnership between the Department of Geography at the Maynooth University and Ireland’s marine mapping programme INFOMAR. The level 9…
Professor Dearbháile Morris, School of Medicine, NUI Galway
More than 90% of samples taken from Irish rivers show the presence of E. coli, according to a new study from NUI Galway. And researchers found that the toxic bacteria was also present in bathing waters which pass muster with…
Authors of the study hold up the square mesh panel, inserted into the otter-trawl net with LEDs attached. Lights help to increase escapement of fish through the large square mesh in the panel
Illuminated exits are as useful to fish as to humans in a tight spot. Newly published research has found that artificial light on square mesh panels in nets can help to reduce unwanted bycatch of fish. The study, published in…
A clownfish and a passing motorboat overhead
Everyone who has ever seen the Pixar film Finding Nemo knows what a clownfish looks like, but a new study gives some alarming insight into their response to human behaviour. A study by international scientists on the impact of motorboat…
Marine chemist Ken Buesseler (right) deploys a sediment trap from the research vessel Roger Revelle during a 2018 expedition in the Gulf of Alaska. Buesseler's research focuses on how carbon moves through the ocean. Buesseler and co-authors of a new study found that the ocean's biological carbon pump may be twice as efficient as previously estimated, with implications for future climate assessments.
The ocean’s biological “carbon pump” has been “drastically underestimated in its ability to capture carbon from the atmosphere, a new study has found writes Lorna Siggins Scientists with the US Woods Hole Oceanographic Institution (WHOI) have found that the depth of…
Dive Deep Into ‘Oceans Of Learning’ Online Resources
Dive deep into the oceans of learning resources available on the Marine Institute’s website via the Oceans of Learning series, which offers downloadable resources, videos and interactive activities exploring our marine resource and marine scientists’ vital work. As the institute’s…

Marine Science Perhaps it is the work of the Irish research vessel RV Celtic Explorer out in the Atlantic Ocean that best highlights the essential nature of marine research, development and sustainable management, through which Ireland is developing a strong and well-deserved reputation as an emerging centre of excellence. From Wavebob Ocean energy technology to aquaculture to weather buoys and oil exploration these pages document the work of Irish marine science and how Irish scientists have secured prominent roles in many European and international marine science bodies.

 

At A Glance – Ocean Facts

  • 71% of the earth’s surface is covered by the ocean
  • The ocean is responsible for the water cycle, which affects our weather
  • The ocean absorbs 30% of the carbon dioxide added to the atmosphere by human activity
  • The real map of Ireland has a seabed territory ten times the size of its land area
  • The ocean is the support system of our planet.
  • Over half of the oxygen we breathe was produced in the ocean
  • The global market for seaweed is valued at approximately €5.4 billion
  • · Coral reefs are among the oldest ecosystems in the world — at 230 million years
  • 1.9 million people live within 5km of the coast in Ireland
  • Ocean waters hold nearly 20 million tons of gold. If we could mine all of the gold from the ocean, we would have enough to give every person on earth 9lbs of the precious metal!
  • Aquaculture is the fastest growing food sector in the world – Ireland is ranked 7th largest aquaculture producer in the EU
  • The Atlantic Ocean is the second largest ocean in the world, covering 20% of the earth’s surface. Out of all the oceans, the Atlantic Ocean is the saltiest
  • The Pacific Ocean is the largest ocean in the world. It’s bigger than all the continents put together
  • Ireland is surrounded by some of the most productive fishing grounds in Europe, with Irish commercial fish landings worth around €200 million annually
  • 97% of the earth’s water is in the ocean
  • The ocean provides the greatest amount of the world’s protein consumed by humans
  • Plastic affects 700 species in the oceans from plankton to whales.
  • Only 10% of the oceans have been explored.
  • 8 million tonnes of plastic enter the ocean each year, equal to dumping a garbage truck of plastic into the ocean every minute.
  • 12 humans have walked on the moon but only 3 humans have been to the deepest part of the ocean.
