  • Preventing sinkholes: avoiding costly repairs

    Examining the causes of sinkholes and how Deep Trekker is aiding in preventing costly repairs and unwarranted closures. When it comes to preventing sinkholes, we must first understand how and why they appear. Armed with this knowledge, we can then take proper action to thwart the sudden appearances of these, costly craters. Sinkholes slowly develop over time in and around areas ...

  • Search and Rescue Demo With Deep Trekker

    Search and Rescue operations are a large part of police divers jobs. While it is never nice to hear about a drown victim, the work that police divers do is extremely important to provide closure to the families involved. Each time a brave diver enters the water there is a number of risks involved, especially when the specific task at hand holds so much weight. One of the most ...

  • Advancing Autonomous Underwater Vehicle Technology

    Autonomous underwater vehicles (AUVs) are a mainstay of the subsea survey industry. With unparalleled speed and accuracy in deep water, they have long been the obvious choice for surveys in inhospitable, deep environments. In light of the current downturn in the oil and gas market and the increasing visibility of autonomous vehicles, such as self-driving cars, AUV technology is poised to break ...

  • Underground, underwater, under stress: Town of Longboat Key puts SmartBall tool to unusual pipeline condition test

    When much of your critical sewer pipeline lies buried under a bay of shimmering ocean water, the challenges required to assess its condition may seem daunting. That task faced the Town of Longboat Key, an affluent retirement community located on the barrier island of the same name off the west coast of Florida. Sensitive to environmental, health and safety issues, ...

  • Dredging Technology – Underwater Excavation and Construction

    The presence of water is ussualy considered a nuisance in construction, particularly when excavating removing water is common practice. In some cases however, water can be a very useful tool that may simplify things greatly. With the “flooded excavation principle”, the construction site is flooded after the retaining walls have been installed (e.g. sheet pile). When the ...

  • Scintillation effect in LISST – The importance of temperature differences

    Scintillation is what makes stars twinkle. It is what causes mirage in deserts or on hot surfaces. It is what causes shimmer underwater in the vicinity of hot vents in oceans. These effects result from temperature fluctuations in air or water. The same effect can occur in a LISST optics cell if not properly controlled . The importance of scintillation in LISST instruments first became evident ...

  • How the LISST-ABS works

    INTRODUCTION: Sequoia’s Acoustic Backscatter Sensor, LISST-ABS is designed to measure suspended sediment concentration at a point. Unlike ADCP’s which may record similar backscatter strength at multiple points along the acoustic beams (‘ranges’), the LISST-ABS  only reports backscatter signal strength at a single point about 5 cm from the transducer. The ...

  • ArmorMax® is Solution for Bank Stabilization in NRCS Emergency Watershed Protection Program, Kissimmee, FL case study

    PROJECT SUMMARY Years of flash flooding and fluctuating water levels in the West City Ditch made for a dangerous scenario. The City of Kissimmee secured NRCS EWPP grant money to stabilize the ditch before catastrophic infrastructure damage occurred, but the budget was too small for full protection with conventional hard armoring. Propex worked with engineers to model slope stability in rapid ...

  • A Sound Projector for Acoustic Tomography and Global Ocean Monitoring

    Abstract—Long-range underwater acoustic systems, such as those used in ocean acoustic tomography, require low-frequency signals covering a broad frequency band. To meet this requirement, a novel design based on of a tunable narrow-band high-efficiency sound projector has been exploited. The projector transmits a frequency sweep signal by mechanically tuning a resonator tube (or organ pipe) ...
