CE20007 INFOMAR hydrographical and geophysical survey took place in March/April 2020 in the North East Atlantic Ocean, off the coast of Ireland and in the Celtic Sea on board the RV Celtic Explorer. The aims of the survey were to undertake a Multibeam Echo Sounder (MBES) hydrographic survey, acquire Sub Bottom Profiler (SBP) data of the shallow (up to 30 m) and to acquire magnetometer data. INFOMAR is a Irish Department of Communications, Climate Action and the Environment (DCCAE) funded joint programme between the Geological Survey Ireland and the Marine Institute, surveying our unmapped marine territory and creating a range of integrated mapping products of the physical, chemical and biological features of the seabed.
