Geophysical Research Survey Off North West Coast In May

#MarineNotice - Maynooth University will carry out a geophysical research survey off the North West Coast of Ireland from next weekend. 

Work is expected to commence on Sunday 6 May and last for approximately nine days, subject to weather conditions.

The Marine Institute’s research vessel RV Celtic Voyager (Callsign EIQN) is scheduled to carry out the works for the Mara survey, undertaken by researchers in Maynooth University to collect geophysical acoustic survey data as well as sediment grab and core samples.

The survey will use relatively low amplitude sound sources to image into the seabed including an echosounder and a sparker system, which will allow for the characterisation of seabed type to inform the deglacial dynamics of the climatically driven British Irish Ice Sheet.

The vessel will, on occasion, be towing a hydrophone cable and other equipment, up to a maximum of 50 metres behind the vessel. The vessel will be restricted in its movements when towing a cable astern.

All other vessels are requested to give the operation a wide berth. The vessel will be listening on VHF Channel 16 throughout the project.

Details of the survey area, relevant co-ordinates and contact information are included in Marine Notice  No 19 of 2018, a PDF of which is available to read or download HERE.

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.
