INFOMAR, a joint venture by the Geological Survey Ireland and the Marine Institute, has launched a collection of 18 high-resolution bathymetric maps of Ireland’s coastal waters. The Blue Scale Map Series is the culmination of over a decade of work and highlights the unique and intricate landscapes lying beneath the waves. 

Each week, INFOMAR will release a new map of a different section of the Irish coastline. The latest in the series is the blue scale bathymetric map of Loop Head, County Clare on the Shannon Estuary. 

The area was first surveyed in 2009 on board the RV Celtic Voyager, with the INFOMAR team mapping a total of 162km2 of seabed along the River Shannon and west of Loop Head. Mapping continued in the region on board the RV Celtic Voyager, RV Keary, RV Geo & MV Cosantóir Bradán between 2011 – 2014, resulting in an area of over 2000km2 of previously unmapped Clare coastal waters being surveyed in high resolution.

Earlier this year, INFOMAR’s inshore team, on board the RV Galtee, continued mapping shallower waters beneath the Iconic Cliffs of Moher, Liscannor Bay and Kilstiffin Reef.

The Blue Scale Map Series offers a new and unique way not only to showcase the mapping effort to date but also to visualize and communicate complex scientific information to the wider public. As with all INFOMAR data, these high-resolution maps are available for free to download and have huge potential to communicate with local coastal communities and raise awareness of the importance of maintaining the health and integrity of our marine environment.

Ireland’s coastline is approximately 3,171km in length and boasts some of the most unique and dynamic marine environments in Europe. Since 2006, INFOMAR’s seabed mapping efforts have been instrumental in enhancing our understanding of Ireland's underwater landscape. The Blue Scale Map Series not only highlights the topography of the coast in remarkable detail but also paves the way for the future management of Ireland’s marine resource.

An underwater survey of Dublin Bay is expected to commence this Friday, (1st October 2010). It is part of a Dublin City Council (DCC) project to upgrade the Ringsend Wastewater Treatment Plant. Preliminary works will include a Bathymetric Survey of Dublin Bay and its approaches and last for a period of approximately one month. The area to be surveyed is attached in a Notice to Mariners issued by Dublin Port Company. The survey will be carried out by a 12 metre yellow hull catamaran "Xplorer". The "Xplorer" is fitted with A.I.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
  • 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.
