Water deeper than 20 m is surveyed by the Marine Institute using the R.V. Celtic Explorer and the R.V. Celtic Voyager. For shallower areas less than 20 metres the Geological Survey manage a fleet of smaller vessels.
The vessels vary in size and specification but all have a Multi-beam Echosounder (MBES) to transmit and receive acoustic pings and measure depth under the boat. This is the basis of our work. The fleet also facilitates shallow seismic surveys, ground-truthing, side scan sonar and ROV operations using state-of-the-art technology and equipment.
Vessels, equipment and survey know-how are explained in this section.
