Conclusion
SONAR survey results used for data interpretation of semi-buried object detection
Geophysical survey method was suppose to give more reliable results
Add another survey method in site investigation
![Page 14: Semi-Buried Seabed Object Detection: Sonar vs. Geophysical ... · Sonar vs. Geophysical methods Dino DRAGUN Lieselot NOPPE, Pierre SERPE Emeline CARON, Astrid ROBERT Thursday, June](https://reader034.vdocument.in/reader034/viewer/2022051913/6004da844960ac3a9c319915/html5/thumbnails/14.jpg)
Suggestion for next site investigation (semi-buried object detection)
2D/3D Sub-bottom imager (data quality not influenced
by surrounding objects)
