Chesapeake Technology (CTI, USA), has presented a new 24-bit analogue sub-bottom SonarWiz interface (SBP24) for high-resolution geophysical surveys. SBP24 provides high-resolution 24-bit data at sample rates from 10 to 100kHz...

Guangzhou Marine Geological Survey (GMGS) in China has awarded Atlas Hydrographic a contract to supply an Atlas Parasound hull-mounted sub-bottom profiler with full ocean depth range capability for its vessel...

Sensor Technology recently designed and delivered a prototype batch of advanced array hydrophones to PanGeo Subsea for deployment on its newly developed Sub-Bottom Imager (SBI). SensorTech designed the custom hydrophones...

Most sub-bottom profilers of the 60s, 70s and 80s were only designed to generate cross-sectional images of seabed sediment layering and other sub-bottom features. The data were degraded by system...

It is likely that you will find sub-bottom profiling equipment onboard most of the survey vessels involved in offshore investigations. Whereas the echo sounder is designed for top-layer investigations, with...

L-3 Klein has launched a CHIRP Sub Bottom Profiler (SBP) attachment for the 3000 Model Side-scan Sonar. The older SBP was a single transducer 3.5kHz "pinger" and delivered satisfactory performance...

EdgeTech has introduced the new 3100 Sub-Bottom Profiling System: a portable solution for sub-bottom imaging. The 3100 System uses Full Spectrum (‘chirp’) pulses to create high definition image slices of...

IHO standard S-44 is often used (or misused) to specify the quality of a hydrographic survey. While it is a useful tool, it is easy to misinterpret. One ‘misuse’ is...

A groundbreaking study has unveiled the discovery of an immense coral reef on the bottom of the Atlantic Ocean, marking the largest deep-sea coral reef ever measured. Spanning approximately 26,000...

EdgeTech, one of the leading companies in high-resolution sonar imaging systems and underwater technology, has recently introduced a new combined tri-frequency sidescan sonar and high-resolution sub-bottom profiling sonar system. The...
