  • A brief statement of airport applications for doppler SODAR systems

    Doppler SODAR Operating similar to a sonar the Doppler SODAR (Sonic Detection and Ranging) directly measures the atmospheric wind speed and direction at multiple altitudes simultaneously. These systems utilize the Doppler effect imposed on the received acoustic signal echoed by the atmosphere for the wind measurements. The Doppler effect is the common observation that the acoustic signal ...

  • Loadtest - Sonicaliper success story

    In June 2008, a project was initiated between SoilVision Systems Ltd. and LoadTest Inc. relating to the development of software to support their newly developed SoniCaliper instrument. Prototype software for processing the data from this instrument had been developed by LoadTest Inc.; SoilVision Systems Ltd. was hired to bring the software to a professional level and implement 3D graphical ...


  • 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 ...

  • Four Major Benefits of Horizontal Hydraulic Auger Dredges

    Horizontal hydraulic auger dredging has been around for nearly 50 years, but remains the unknown stepchild of the dredging world. That may be changing as environmental dredging becomes more prominent. Horizontal hydraulic auger dredges are ideal for environmental projects for several reasons. First, horizontal hydraulic auger dredges are small. I know everybody wants bigger, but small has ...

  • Underwater Bridge Inspections – Drones Conducting Remote Evaluations

    Deep Trekker Remotely Operated Vehicles (ROV), or underwater drones, are establishing themselves as the ideal tool for underwater bridge inspections. It goes without saying that the structural integrity of a bridge is extremely important; after all, you’re only either walking, driving, or riding a train across it. With the public safety in mind and to continue the flow of traffic, these ...

  • Visualizing the stories data can tell

    Scientists and technologists are turning numbers about everything from condors to ocean-floor contours into visual representations of environmental issues. We’re living in an era of Big Data, but too often it’s nothing more than a fire hose of numbers and data sets that most would have difficulty understanding. Increasingly, though, entities such as non-governmental ...
