Minister for Natural Resources, Conor Lenihan, T.D., has joined 4th class pupils from St. Pius X Girls national school, Terenure on a field trip of the River Dodder. The purpose of the field trip was to analyse the water quality of the River Dodder, a river that is very important in south Dublin.

In preparation for the field trip Des Chew, Project Manager of the Dublin Angling Initiative visited the school and gave the pupils a talk on water quality, the lifecycle of trout and the art of fly-fishing. The pupils then participated in a field trip along the River Dodder, starting at Rathfarnham shopping centre and finishing at the confluence of the Dodder and Owendore rivers at Bushy Park. Minister Lenihan was joined by TV celebrity and angler Derek Davis.

Fisheries staff from Dublin Angling Initiative and Inland Fisheries Ireland took kick samples and were ably assisted by Gerry Heaslip and Brian McDonagh of the Dodder Angling Club. The children identified invertebrates and their delight could be heard far and wide as they found many different species of stonefly and caddis fly! Looking at water pollution indicators, the children could establish that the presence of these different types of invertebrates indicated the good water quality in the river. This is not surprising given the very healthy stock of wild brown trout in the river.

Minister Lenihan, remarked:

'It is wonderful today to see the young people out learning about their local river. The River Dodder is a very important river in south Dublin, it has good water quality, contains a healthy population of wild brown trout and is a wonderful angling resource.

This is in no small part due to the excellent relationship that the Dublin Angling Initiative and Inland Fisheries Ireland have with the Dodder Angling Club'.

Following this the children were given information packs on fish species, invertebrates and fish species posters. St. Pius X School has participated in Inland Fisheries Ireland's 'Something Fishy' programme in previous years and were thrilled to take part in such an exciting field trip of their local river.

The 'Something Fishy' project was developed by Inland Fisheries Ireland (formerly the Central and Regional Fisheries Boards) in association with Blackrock Education Centre and has proved a highly successful way of encouraging young people to take an interest in Irish fish species, their local environment and habitat. In 2010 almost 1,000 young people participated in the Something Fishy programme within the Eastern River Basin District.

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
