Coastal acoustic tomography system and its field application
IEEE Journal of Oceanic Engineering, 2002The coastal acoustic tomography system (CATS), composed of five moored acoustic stations, has been constructed to measure current fields. The system is developed with special considerations in mind, including the use of Global Positioning System clock signals in the synchronization of the system clock timing among the multiple acoustic stations, and ...

A multistation coastal acoustic tomography system with coherent operation
The Journal of the Acoustical Society of America, 2006A multistation coastal ocean acoustic tomography (CAT) system with coherent operation has been developed and applied to field experiments over ten times in the last 8 years. The system is designed to measure both temperature and current velocity fields in the coastal ocean.

Short-range velocity field observation by coastal acoustic tomography
OCEANS 2019 MTS/IEEE SEATTLE, 2019Coastal acoustic tomography can perform a realtime field observation, and can be an important supplement to the Marine Ranch Observation. In this paper, a short range experiment has been conducted in ZhaiRuo Island, ZhouShan on January 20,2019. Four acoustic stations sent signals to each other to obtain the travel time of the signal between stations ...

Acoustic tomography of a coastal front in Haro Strait, British Columbia
The Journal of the Acoustical Society of America, 1999An experiment validating the concept of acoustically focused oceanographic sampling (AFOS) was recently implemented in Haro Strait, British Columbia (Canada). Four 16-element vertical receiver arrays were moored around the location of a coastal front driven by estuarine and tidal forcing.

2010 Sixth International Conference on Natural Computation, 2010
An inverse model for coastal acoustic tomography (CAT) to reconstruct the tidal current distributions was built and applied to the Zhitouyang Bay near the Zhoushan Island, China. The range-averaged current (post-inversion result) obtained along the transmission lines by the inverse model showed a prominent semidiurnal oscillation and was in good ...

The application of coastal acoustic tomography to a large experimental wave/current basin
Journal of the Acoustical Society of America, 2016This article describes the use of acoustic tomography to characterize the flow pattern in the Flowave basin. Flowave is a unique circular wave/current basin, 2 m deep and 25 m in diameter. Current can be created in any direction at speed of up to 1.2 ms.-1.

Acoustic current tomography of a coastal front in Haro Strait, British Columbia
The Journal of the Acoustical Society of America, 1996Various tomographic approaches are investigated for determining the spatial and temporal characteristics of the current field in the vicinity of a tidally forced coastal front near Stuart Island in Haro Strait, British Columbia (Canada). The front separates water masses with a current differential of 3 kn or more, corresponding to Mach numbers of 0.001
