  1. 3D models of sound propagating in shallow water Alexander Tshoidze Voronezh State University

  2. 50-200 m Scheme of the shallow water problem model Antenna Horizontal linear array (HLA) Vertical Linear array (VLA) at two depths source 60-600Hz Range 10-100 km

  3. What model do we construct Acoustical model of intensity fluctuations of sound propagating in presence of temperature front, internal waves, depth slopes and other waveguide obstacles.

  4. Polar front in the Barents sea Oceanographic data was given by James F. Lynch from Woods Hole Oceanographic Institution, MA, USA

  5. The chart of horizontal refraction in the area close to temperature front Northern-Atlantic current Arctic current

  6. My publications on the topic 1. B. Katsnelson, J. Lynch, A. Tshoidze Space-frequency distribution of sound field intensity in the neighborhood of a temperature front in shallow water // Acoustics Journal,August, 2007. 2. B. Katsnelson. A.Tshoidze, J.Lynch, Ta-Wei Wang Space frequency sound field distribution in the neighborhood of a temperature front // 147 Meeting Acoustical Society of America, San Diego, JASA, Vol. 116, Issue 4, 2004, Pp.2535-2536. 3.

  7. My speech at the meeting on the topic

  8. Propagating of complex signal

  10. Link to experiment Shallow Water Acoustic Remote Measurements (SWARM’95) A kind of data from our American colleagues New Jersey continental shelf, USA

  11. Correlation of our model with the experiment … and results! Data processing …

  12. Delaware workshop on SWARM’95 April, 2005

  13. Delaware workshop is going on

  14. Future work • Creating complex sound • field model, especially phasefront model • 2. Comparing results of our model with data of the experiment SWARM’06 Supported by CRDF VZ-010-0, RFFR 03-05-64568
