Publications

• Atallah,L., Shang, C., and Bates, C.R., (2005) " Object detection at different resolution in archaeological side-scan sonar images. " (PDF file, 552 kB)
  Addresses the detection of objects on the sea floor from side-scan images using scale saliency algorithms
• Bates, C.R. and Oakley, D.J., (2004) "Bathymetric sidescan investigation of sedimentary features in the Tay Estuary, Scotland." Int. J. Remote Sensing 25.22 5089–5104 (PDF file, 675 kB)
  Static fronts in the Tay estuary exist at well-defined bathymetric changes and result in relatively stable bedforms. Remote sensing data indicates that these frontal systems are controlling the distribution of sedimentary features in the estuary.
• Bates, R. and James, B., "Marine GIS for Management of Scottish Marine Special Areas of Conservation." (PDF file, 104 kB)
  An overview of the procedures developed by the Universities of St. Andrews and Heriot Watt that enable a rapid turnaround in the processing of broadscale acoustic survey information gathered within marine Special Areas of Conservation (SAC) sites around the Scottish coastline.
• Bates, R. and Moore, C., "Acoustical Methods for Marine Habitat Surveys." (PDF file, 291 kB)
  A review of methodologies capable of monitoring marine habitat change, with examples from Special Areas of Conservation in Norway and the west coast of Scotland.
• Bates, C.R. and Whitehead, E.J., "ECHOplus Measurements in Hopavågen Bay, Norway." (PDF file, 339 kB)
  An evaluation of the ECHOplus Seabed Discrimination System, a single-beam acoustic technique which involves the analysis of first and second echoes from the vessel’s echo sounder. Algorithms can assess the 'hardness' and 'roughness' of the seabed, criteria which are potentially useful for habitat mapping. The acoustic map of bottom reflectance (hardness and roughness) is shown to be verified by data obtained from grab, diver and video surveying.
• Lawrence, M., Oxley, I. and Bates, R., "Geophysical Techniques For Maritime Archaeological Surveys." (PDF file, 153 kB)
  The results of multibeam sonar and acoustic ground discrimination sonar (AGDS) tests at two historic wreck sites on the UK shelf, namely the Stirling Castle, Goodwin Sands, England and the SMS Cöln, Scapa Flow, Scotland, and their implications for archaeological heritage management.
• Lawrence, M.J. and Bates, C.R., "Acoustic ground discrimination techniques for submerged archaeological site investigations." (PDF file, 284 kB)
  The use of single beam acoustic ground discrimination systems (AGDS), based on standard echo sounders, to classify seabed type and map submerged archaeological materials.
• Bates, C.R. and Byham, P., "Swath-sounding techniques for near shore surveying." (PDF file, 1.7 MB)
  The high bathymetric resolution and complete 3D coverage offered by the swath-sounding technique provides insights into complex sea floor geology and allows evaluations of dynamic sediment movements. Bathymetry and co-located amplitude measurements provide means for habitat appraisal.
