Figure 3: In the right image, multibeam data is plotted with a surfacing pipeline. Crosslines can be seen on top of the multibeam data indicating the location of the sub-bottom profi les. The sub-bottom seismic data of the red (lower) crossline is shown on the left with clear hyperbole. Conclusion Sub-bottom profi ling can be successfully used to detect linear objects within the bottom. The automated contact recognition of Silas detects objects in an automated way. The calculated quality parameters allow for a quantifi able interpretation and the comparison with the theoretical hyperbola increases the ease of manual interpretation. The combination with other datasets increases the quality of interpretation in sub-bottom acoustics. Related products EBP Silas Biographical notes References DE BOER, P.J., WERNER, C.J.
