The survey was to inform planning for the development of a wave energy project in the area.

Data was simultaneously logged in Kongsberg SIS and HYPACK HYSWEEP software to ensure data redundancy were a computer to fail. R2Sonic 2024 – The Sonic 2024 was controlled via the Sonic Control 2000 program. Data was logged in Hypack during the data gathering phase. After data gathering all data was post processed in HYPACK MBMax where the following stages of processing were undertaken: ß Navigation data was processed. ß Motion Sensor data was examined and edited as required. ß Automatic filtering of the data was carried out. ß Individual lines of MBES sounding data were manually edited. ß Processed files were loaded into Fledermaus visualisation and editing software and fully quality assured before being unloaded back to Hypack. ß The data was gridded at an appropriate post spacing for the scale of plot requested by the client. This was exported to AutoCAD for presentation. ß The data was contoured at 1m intervals in Hypack and exported to AutoCAD. ß X,Y, Z, files at 0.5m post spacing were generated and exported in Hypack. These higher density data files will be rendered to the client in ASCII X,Y,Z format. Data was then transferred to Fledermaus for quality control and preparation of 3D visualisations. The SEG-Y data gathered by the Edgetech 3100P 2-10KHz sub bottom profiler was processed in Chesapeake SonarWiz.MAP software. The following stages were undertaken: ß SEG-Y data was imported to the software. ß The Gain and Time Variable Gain settings were adjusted to ensure that the best possible picture of the sub bottom data was available to the user. ß Each individual horizon was digitised including: o Surface o Sediment horizon 1 o Sediment Horizon 2 o Isolated Reflectors - Point Hyperbolae sonar returns within the sediment o Rockhead / Glacial Till ß Each horizon was referenced to the Multibeam Bathymetry to ensure a coherent record. ß Individual horizons were exported to McCarthy Taylor Systems LSS (3D modelling software) where it was gridded, contoured and prepared for export to AutoCAD. ß Drawing files prepared in AutoCAD to represent the deliverables requested by the client. ß SEG-Y data was saved to DVD as requested and rendered to the client.
