  • 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) ...

  • Managing oceans with sound science

    Management of marine resources for sustainable development needs local capacity for science, particularly in the Pacific region. Those who care about environmental damage and its effects on the health and welfare of communities tend to focus on land-based threats. That is where harm can be most easily observed, and where its causes — from agricultural pesticides to industrial air ...

  • Impact of sound attenuation by suspended sediment on ADCP backscatter calibrations

    Abstract. Although designed for velocity measurements, acoustic Doppler current profilers (ADCPs) are widely being used to monitor suspended particulate matter in rivers and in marine environments. To quantify mass concentrations of suspended matter, ADCP backscatter is generally calibrated with in situ measurements. ADCP backscatter calibrations are often highly site-specific and season ...
