The data consisted of sidescan sonar, sub-bottom profiler (sparker), multibeam bathymetry and marine magnetometer data. This review included an assessment of these results in conjunction with historical data and a previous desk-based assessment for the Irish Sea Zone, which forms Phase II of the Zonal Appraisal and Planning process. The assessment focused on the potential for remnant land surfaces that may contain archaeological material relating to times of lower sea level, and the potential for the remains of maritime craft or aircraft of cultural heritage importance within the area that may be impacted upon by development within the Irish Sea Zone.
