    AbstractThe HABMAP project aimed to provide seabed habitat maps that could be used for conservation and management. The project was carried out in the southern area of the Irish Sea and north-eastern part of the adjoining Celtic Sea. It was a partnership between several organisations in Wales and Ireland, partly funded by the INTERREG IIIa European Regional Development Fund for cross border projects between Wales and Ireland. There were two main components to the project; collection of new survey data and mapping seabed habitats using data collation and predictive modelling. The objective of the first cruise was to collect high resolution bathymetric and acoustic backscatter data. All survey work was carried out on board the R.V. Celtic Voyager (Marine Institute, Ireland) in 2005. All MBES data for HABMAP were acquired to Irish National Seabed Survey (INSS) standard. A hull-mounted Simrad EM1002 multibeam echosounder system was used to collect all of the MBES. Vertical resolution was better than 0.2% of water depth, excluding position, attitude and refraction uncertainties. Differential Global Positioning System (DGPS) data were continuously acquired to ensure that the seabed sounding data were correctly located. Multibeam echosounder data collected were processed using CARIS© HIPS and SIPS hydrographic software package versions 5.3 and 5.4. Depths were reduced to “Chart Datum”, and were corrected for tidal range. Tidal information was provided primarily by a Proudman Oceanographic Laboratory tidal computation system (POLPRED). Portable gauge data to correct for tidal ranges in the survey area off Arklow.
