    AbstractThis area was surveyed by INFOMAR on board survey vessel RV Celtic Explorer during cruise CE17_02 Celtic Sea between 22/09/2017 and 02/10/2017. The scientific aims of the survey were to: (i) Undertake a Multibeam Echo Sounder (MBES) hydrographic survey to International Hydrographic Organisation (IHO) Order 1a standard in water depths of less than 100 metres and to Order 2 in water depths greater than 100 metres.(ii) Produce bathymetry, shaded relief and backscatter mosaic products to provide depth, seabed features and seabed hardness information. (iii) Acquire Sub Bottom Profiler/Chirp data of the shallow (up to 30 metres) sub seabed to determine the existence of buried objects and ascertain the sub-seabed character. (iv) Acquire sediment cores (vibrocorer) and a few cross seismic lines (sparker) over geological or glacially related features observed during previous survey legs on the SW coast of Ireland. Primary hydrographical and geophysical permanently mounted equipment consist of two MBES (hull mounted EM302 and drop keel mounted EM2040), a EA600 Singlebeam Echo sounder (SBES), Chirp source SBP and C-NAV Differential Global Navigation Satellite Systems (DGNSS) and a Seatex Seapath 330+ Positioning and motion reference unit. All necessary geophysical and DGPS positioning equipment were pre-installed, calibrated and tested prior to commencement of survey activities.
