#MarineScience - Marine Institute's RV Celtic Explorer departed Galway yesterday for the first deepwater INFOMAR survey of 2018 to map the seabed in the region of the Labadie and Cockburn Banks, south of the Celtic Sea.

These areas are of ecological and economic value to the Irish fishing fleet and the data collected will allow better fisheries management decisions.

INFOMAR, the national seabed mapping programme, is a joint programme between the Geological Survey of Ireland (GSI) and Marine Institute. INFOMAR creates bathymetric charts and products for Ireland's coastal and deeper offshore waters using acoustic sonars called multi-beams. The survey team will be led by Vera Quinlan, and include four INFOMAR surveyors / scientists and four marine science students.

Three multi-beam echo sounders on the marine research vessel will transmit beams of sound towards the sea floor. These 'beams of sound' are reflected off the sea floor and both the time it takes to receive the returned signal and the intensity are captured by the on-board systems. This process provides a very clear picture of the shape and texture of the seafloor, such as the bathymetry, and the geological characteristics of the area.

Further studies include the analysis of the radiation patterns of the sonars resulting in increased precision and improved data. This is part of a long-running collaboration between INFOMAR and Professor John Hughes Clarke at the Centre for Coastal and Ocean Mapping at the University of NewINFOMAR survey to map the Celtic Sea seabed Hampshire.

The survey team includes two students from the United States of America, Alexandra Dawson and Treyson Gillespie, from the BEAMS (BEnthic Acoustic Mapping and Survey) Program. BEAMS is an undergraduate-focused training and research program from the College of Charleston's Department of Geology and Environmental Geosciences, and aims to develop a strong and qualified workforce of ocean surveyors in support of the academic, research and operational marine communities.

INFOMAR also welcomes Becky Cronin and Rachel O' Mahoney from the Training Through Research Surveys (TTRS), a collaboration with the Marine Institute. The programme aims to increase national capacity in offshore marine research by offering seagoing placements for students of marine related sciences and technologies on the national research vessels, RV Celtic Explorer and RV Celtic Voyager.

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.

At A Glance – Figaro Race

  • It starts in June or July from a French port.
  • The race is split into four stages varying from year to year, from the length of the French coast and making up a total of around 1,500 to 2,000 nautical miles (1,700 to 2,300 mi; 2,800 to 3,700 km) on average.
  • Over the years the race has lasted between 10 and 13 days at sea.
  • The competitor is alone in the boat, participation is mixed.
  • Since 1990, all boats are of one design.
