Irish Research Marine Glider Deployed In North Atlantic On New Project

The Marine Institute’s marine glider has been deployed in the North Atlantic as part of a deep ocean marine science research project.

Laochra na Mara can reach depths of 1,000m and collects oceanographic data on conductivity, temperature, depth, fluorescence, turbidity and dissolved oxygen.

The glider was deployed from the RV Águas Vivas as part of the fifth project meeting for the Innovation in the Framework of the Atlantic Deep Ocean (iFADO) project recently held in The Azores, Portugal.

Prior to deployment, the glider was exhibited to the public at the Horta Maritime Terminal where local school students met iFADO team members and viewed several videos about glider operations and missions.

The school students also wrote messages on the glider before it was launched.

“Equipped with a wide variety of sensors, the glider can gather information about ocean temperature, salinity and currents, and transmits this information to shore via satellite,” Thomas Dabrowski of the Marine Institute said.

“Gliders are able to provide real-time data, and provide a better assessment and understanding of our ocean environment.”

Gliders are programmed to surface at designated times and transmit the data collected while at the same time downloading new mission instructions. This two-way communication allows gliders to continually gather information about the most important and diverse regions of our ocean basins 24 hours a day.

Similar to a glider from the United States that was found off Baltimore in 2017, the Slocum glider was recently recovered in the North Atlantic Ocean after 15 days at sea — during which it covered over 250km and performed over 40 deep dives.

The fifth iFADO project meeting gathered 50 participants and partner leads to hear the latest results and discuss future co-operation and follow-up action.

The iFADO project aims to create marine services at regional and sub-regional scale using the EU’s Atlantic waters as a case study. It combines traditional monitoring with cost-effective state-of-the-art technologies such as remote sensing, numerical modelling and emerging observation platforms such as gliders and oceanic buoys.

The Marine Institute is one of 20 partners from Ireland, the UK, France, Portugal and Spain involved in the iFADO project. The project has received funding from the European Union’s Interreg Atlantic Area Programme.

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.
