Visualising the amount of freshwater released from Antarctic Iceberg A-68A
A giant iceberg that snapped off Antarctica’s Larsen-C ice shelf some three and a half years ago shrank towards the end of its drift across the Southern Ocean, but released 152 billion tonnes of freshwater. The European Space Agency (ESA)…
The Great Pacific Garbage Patch as modelled in 2017
Plastic pollution in the world’s oceans has changed ecosystems so much that now marine wildlife and plantlife are using it as the foundation of new habitats, it’s being claimed. Marine Industry News reports on research conducted on the so-called Great…
Lightweight microplastics can be trapped in freshwater sediment and stay longest at “headwaters” or sources of rivers and streams, a new study has found. It can then take up to seven years for such pollutants to travel just a kilometre…
Fionnán Ó Baoill (13) built a wave energy tank out of containers in his back garden to test out his theory that fin design could influence optimum use of energy generated by the sea
A Dublin student whose love of sailing inspired him to research wave energy has won second prize in his category at this year’s BT Young Scientist and Technology Exhibition. Fionnán Ó Baoighill built a wave energy tank out of containers in…
Dara McGee's - ' Coconuts with and without husks, along with Sea Heart (Entada gigas) Fanore, Co Clare, 20.07.2019

The latest Marine Notice from the Department of Transport advises that the Informing and Mapping the Offshore Renewable Environment (I-MORE) Survey will be carried out in the North Irish Sea from early in the New Year. From 4-13 January 2022,…
Map showing microplastic data captured during The Ocean Race Europe
New research from The Ocean Race Europe has found microplastics, and in particular microfibres, to be prevalent across the length and breadth of Europe. All 36 water samples collected around the continent — including in the Baltic Sea, the English…
New research from Queen’s University Belfast has led to 184 deep-sea species being added to the global “Red List” of threatened species. The International Union for Conservation of Nature (IUCN) is the world’s foremost conservation authority, and its “red list”…
Athy museum said it was particularly fitting in the approach to the centenary of Ernest Shackleton’s death in January 2022
The Shackleton Museum in Co Kildare has welcomed a commitment by Minister for Foreign Affairs Simon Coveney to ensure Ireland signs up to the Antarctic Treaty. The Athy museum said it was particularly fitting in the approach to the centenary…
Dr Ciaran Kelly, Director of Fisheries Ecosystem Advisory Services at the Marine Institute with the 2021 Stock Book
The Marine Institute has today launched the 2021 Stock Book, the annual publication which provides the latest impartial scientific advice on the status of 74 key fish stocks of interest to Ireland. It is available for download or through an…

Two shellfish projects will benefit among the awards made under the Department of Agriculture, Food and the Marine’s 2021 call for research proposals. Marine Minister Charlie McConalogue and Minster of State Martin Heydon jointly announced the awards today (Monday 6…
Sea angling off the coast of Co Wexford
The State agency responsible for the conservation and protection of sea angling resources has developed an important new tool that captures anglers’ knowledge and hands-on experience to help track changes in stocks of marine fish. According to Inland Fisheries Ireland…
LAUNCH: The hull of Ireland’s new marine research vessel RV Tom Crean makes its first splash at Astilleros Armon shipyard in Vigo, Spain. A significant milestone in the build process, with the vessel on schedule for the Marine Institute and to be completed in summer 2022.
Ireland's new state-of-the-art marine research vessel, RV Tom Crean, was today launched as the hull went into the water for the first time from the Astilleros Armon shipyard in Vigo, Spain. The launch of the hull is a significant milestone…
A Kerry councillor's call is to have the Marine Institute's newbuild research vessel (RV) Tom Crean be named in the south-west county in honour of the Annascaul-born Antartic explorer.
A Kerry county councillor says it's appropriate that a vessel to be named after Kerry's Antarctic explorer would officially take place in the county. The Marine Institute has commissioned a new research vessel, which is to be named the RV…
UK and Irish seaweeds may significantly reduce GHG agricultural emissions and provide extra health benefits when used as a supplement for farm animals
As Cop26 continues to debate methane – with the US And EU having pledged to reduce agricultural methane outputs from ruminant livestock by upwards of 30% by 2030 – scientists at the Institute for Global Food Security (IGFS) at Queen’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
