Living Beyond Our Means

That is not a title referring to the current economic situation, though it is certainly apt in that regard. I am using it to refer to the fact that as humans we live on relatively small pockets of land on this planet that is dominated by the oceans upon which we depend for life. So much damage is being done to those oceans that 600 marine scientists this week issued a sombre warning:

"It is well past the time to get serious about measuring what is happening to the seas around us."

I was looking this week at an interesting sight, an image of the Earth taken from outer space in which our planet appears as a globe, dominated by a huge drape of blue hues broken up by irregular patches of brown and green, with swirls of grey and white above them. The blue are the oceans, the patches of brown and green the land and the swirls of grey and white the clouds. It made me think that, if life had evolved on another planet and scientists from there were looking at Earth, they would see it as a water planet, dominated by the oceans which cover over 70 per cent of its outer surface.
The oceans are what set Earth apart from other planets in the solar system. They contain over 324,126 cubic miles of water, an enormous quantity of liquid upon which life on the planet depends. We humans, who lack the ability to live totally in water, who do not possess the gills with which marine life is equipped, who are land-bound, air-breathing organisms, have forgotten how unrepresentative is our perspective of land in relation to the oceans. They occupy two-thirds of the world on which we humans live and which we believe was made for us. Yet, there is much more life in the seas. Isn't that an interesting thought, particularly as human life continues to abuse the oceans?

POGO is an organisation linking 80 per cent of the world's institutions studying the oceans. The "Partnership for Observation of the Global Oceans" was created by leaders of the world's major oceanographic institutions. One of its major aims is to reach out to the public, creating more awareness of the seas. It has now established 'Oceans United,' an international forum intended to become 'The Voice of the Oceans,' sharing observations, knowledge and information for the benefit of humanity which depends for its continued existence on the survival of the oceans.

The 600 marine scientists who issued that sombre warning are members of 'Oceans United.' They have called for an integrated global ocean observation system which would monitor the entire ocean surface:

"The situation is that serious. Every country in the world needs to unite, irrespective of their differences, because the ocean surface is now more acidic than ever before and this will affect life on our planet."

The danger from this rising trend is that it will affect the basis of life in the sea – the plankton which are at the base of the global marine food chain. This is not a remote, ethereal issue. Scientists are concerned that the origins of recent world catastrophes such as the floods in Pakistan and summer heat waves and forest fires could be traceable to effects on the oceans as they grow saltier, hotter, more acidic and thus less biologically diverse.

Marine Institute Research Vessel Tom Crean

Ireland’s new marine research vessel will be named the RV Tom Crean after the renowned County Kerry seaman and explorer who undertook three major groundbreaking expeditions to the Antarctic in the early years of the 20th Century which sought to increase scientific knowledge and to explore unreached areas of the world, at that time.

Ireland's new multi-purpose marine research vessel RV Tom Crean, was delivered in July 2022 and will be used by the Marine Institute and other State agencies and universities to undertake fisheries research, oceanographic and environmental research, seabed mapping surveys; as well as maintaining and deploying weather buoys, observational infrastructure and Remotely Operated Vehicles.

The RV Tom Crean will also enable the Marine Institute to continue to lead and support high-quality scientific surveys that contribute to Ireland's position as a leader in marine science. The research vessel is a modern, multipurpose, silent vessel (designed to meet the stringent criteria of the ICES 209 noise standard for fisheries research), capable of operating in the Irish Exclusive Economic Zone (EEZ). The Tom Crean is able to go to sea for at least 21 days at a time and is designed to operate in harsh sea conditions.

Irish Marine Research activities

The new state-of-the-art multi-purpose marine research vessel will carry out a wide range of marine research activities, including vital fisheries, climate change-related research, seabed mapping and oceanography.

The new 52.8-metre modern research vessel, which will replace the 31-metre RV Celtic Voyager, has been commissioned with funding provided by the Department of Agriculture, Food and the Marine approved by the Government of Ireland.

According to Aodhán FitzGerald, Research Vessel Manager of the MI, the RV Tom Crean will feature an articulated boom crane aft (6t@ 10m, 3T@ 15m), located on the aft-gantry. This will be largely used for loading science equipment and net and equipment handling offshore.

Mounted at the stern is a 10T A-frame aft which can articulate through 170 degrees which are for deploying and recovering large science equipment such as a remotely operated vehicle (ROV’s), towed sleds and for fishing operations.

In addition the fitting of an 8 Ton starboard side T Frame for deploying grabs and corers to 4000m which is the same depth applicable to when the vessel is heaving but is compensated by a CTD system consisting of a winch and frame during such operations.

The vessel will have the regulation MOB boat on a dedicated davit and the facility to carry a 6.5m Rigid Inflatable tender on the port side.

Also at the aft deck is where the 'Holland 1' Work class ROV and the University of Limericks 'Etain' sub-Atlantic ROV will be positioned. In addition up to 3 x 20’ (TEU) containers can be carried.

The newbuild has been engineered to endure increasing harsher conditions and the punishing weather systems encountered in the North-East Atlantic where deployments of RV Tom Crean on surveys spent up to 21 days duration.

In addition, RV Tom Crean will be able to operate in an ultra silent-mode, which is crucial to meet the stringent criteria of the ICES 209 noise standard for fisheries research purposes.

The classification of the newbuild as been appointed to Lloyds and below is a list of the main capabilities and duties to be tasked by RV Tom Crean:

  • Oceanographic surveys, incl. CTD water sampling
  • Fishery research operations
  • Acoustic research operations
  • Environmental research and sampling operation incl. coring
  • ROV and AUV/ASV Surveys
  • Buoy/Mooring operations
