Application of high-resolution geophysical methods in submarine pipeline inspection
High-resolution marine geophysical equipment employed includes single beam echo sounder (SBES), multi-beam echo sounder (MBES), sub-bottom profiler (SBP) and side scan sonar (SSS). By employing SBES, the reflection curve in shallow water reveals the real condition of pipeline; while in deep water, the reflection or diffraction curve can't reveal the real condition. Compared with SBES, MBES is ...

Mapping sediment thickness case study
Polk County, Florida Bathymetric and sub-bottom surveys were conducted within a clay settling pond at a Phosphate mine in Central Florida. Prior to the geophysical survey, a depression or slump had formed along the northern dam of the pond. The purpose of the study was to map various sediment layers within the pond to help determine if the depressions or slumps were related to sinkhole activity ...
