Atlantic Climate Change Survey Finds Deeper Ocean Penetration Of CFCs

#ClimateChange - Preliminary results from the recent ‘health check’ of the Atlantic Ocean suggest a greater penetration of manmade chlorofluorocarbons (CFCs) further into the deeper ocean since 20 years ago.

As previously reported on Afloat.ie, an Irish-led international team of marine scientists from six countries set out from Newfoundland on 27 April on board the RV Celtic Explorer, to survey a transect of the Atlantic last measured two decades ago and investigate the impact of climate change on the deep ocean.

Explaining the team’s findings, Dr Evin McGovern of the Marine Institute and principal investigator on the GO-SHIP A02 survey said: “Although these chemicals have been phased out, they remain in the atmosphere and enter the ocean, where over time, they travel to the deep ocean.

“We measure the CFCs to tell the age of the water masses in the deep ocean and this helps us assess the uptake of fossil fuel carbon from the atmosphere and penetration into the deep ocean.”

The survey formed part of the Global Oceans Ship-Based Hydrographic Investigations Programme (GO-SHIP), which carries out systematic and global surveys of select hydrographic sections, through an international consortium of 16 countries and laboratories.

This was the first GO-SHIP survey to involve such a level of collaboration, with scientists from 10 leading universities and research institutes representing six countries.

Canadian Ambassador to Ireland Kevin Vickers visited the RV Celtic Explorer to meet the team in Galway following their arrival on Monday 22 May.

“This survey is a wonderful example of the Galway Statement in action as well as the longstanding collaboration on marine research between Ireland and Canada,” he said.

Marine Institute chief executive Dr Peter Heffernan added that the expedition’s scientists “are contributing to addressing some of the biggest questions for society and our interaction with our planet.”

We've got a favour to ask

More people are reading Afloat.ie than ever thanks to the power of the internet but we're in stormy seas because advertising revenues across the media are falling fast. Unlike many news sites, we haven’t put up a paywall because we want to keep our marine journalism open.

Afloat.ie is Ireland's only full–time marine journalism team and it takes time, money and hard work to produce our content.

So you can see why we need to ask for your help.

If everyone chipped in, we can enhance our coverage and our future would be more secure. You can help us through a small donation. Thank you.

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.
