Ireland has two marine research vessels, the RV Celtic Explorer and the RV Celtic Voyager. These vessels are used for fisheries and oceanographic research, seabed mapping and climate studies. The RV Celtic Explorer can stay at sea for up to 35 consecutive days and is at sea for about 300 days every year.
