Extreme marine events such as marine heat waves are increasingly threatening to degrade ocean ecosystems and seafood security with potential devastating consequences to aquatic related businesses.

In order to prepare for such events, the Marine Institute, with colleagues in the Horizon 2020 Innovation Action EuroSea project, has developed a new marine observatory specifically designed to address the needs of the aquaculture sector.

The observatory web platform provides an early warning system that can be accessed at eurosea.marine.ie with a help-desk service for end users to provide suggestions or comments on their user experience.

Frequent end-user interaction was essential from the beginning of the project to ensure the service was in agreement with the needs of the industry.

This observatory integrates data from multiple ocean observing platforms (in-situ databuoys; satellites; numerical models) and provides easy access to information about the oceanographic processes affecting the fish farm facilities and its neighbouring waters.

During the EuroSea project, two oceanographic moorings with sensors developed by Xylem were deployed at the pilot sites at Deenish Island in Co Kerry and El Campello on the Costa Blanca in south-eastern Spain.

For the Irish site, satellite observations of ocean colour and sea surface temperature are provided together with information on the occurrence of marine heat waves.

The web portal also provides access to sea surface temperature historical data, starting from 1982, for any site within the Irish Exclusive Economic Zone (EEZ) selected by the user in an interactive application.

Modelled forecasts (eg water temperature, significant wave heights) are linked to the warning system for the EuroSea demonstration sites with a facility for end users to receive notifications on their phone. The thresholds that trigger these warnings were agreed with the end-users when the system was developed.

Finally, best practice guidelines were developed for other partners around the world who plan to develop similar marine observatories. As such, the software is open-access and a scientific paper was recently published in Frontiers in Marine Science.

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
