Celtic Explorer
The RV Celtic Explorer is a 65.5m multi-purpose research vessel. The vessel can accommodate 35 personnel including 20-22 scientists. The Celtic Explorer is suitable for fisheries acoustic research, oceanographic, hydrographic and geological investigations and can also accommodate the ROV Holland I as well as other ROVs. The Celtic Explorer can spend up to 35 consecutive days at sea.

Celtic Voyager
The RV Celtic Voyager is the smaller of our two research vessels at 31.4m in length and can accommodate 6-8 scientists. Maximum number of consecutive days at sea is 14. The Celtic Voyager is suitable for coastal research and offshore survey operations and is used for a variety of applications including fisheries research, environmental monitoring, seabed mapping, oceanographic work, buoy maintenance and student training.

Deepwater ROV
The Marine Institute’s Remotely Operated Vehicle (ROV) Holland I is named after John Phillip Holland from Co. Clare, Ireland who was an early inventor and builder of submarines. Purchased in 2008 with the support of the European Regional Development Fund (ERDF) the Holland I can reach depths of up to 3000 metres and is fitted with high definition video and stills cameras. It is capable of picking up delicate samples from the seabed and is also able to accommodate a wide variety of scientific equipment.
Glider Laochra Na Mara
The Marine Institute operates two 1000m rated Teledyne Webb Slocum G3 gliders, Laochra na Mara and Aisling na Mara. The gliders are part of EirOOS – the Irish Ocean Observing System which is a component of the European Ocean Observing System (EOOS).

Foreign Vessel Surveys
Foreign vessels conduct a number of marine scientific research programmes in Irish waters each year. The Foreign Vessel Observer Scheme (FVOS) is a Marine Institute programme whereby Irish marine researchers can be placed on-board the vessels for the duration of the survey. Further information and summary details of the surveys are available here.
