AMPLE - A software package for the modeling of acoustic fields in shallow water based on the wide-angle mode parabolic equations theory

AMPLE (Ample-angle Mode ParaboLic Equation) - A software package for the modeling of acoustic fields in shallow water based on the wide-angle mode parabolic equations theory

 

Software package was developed at Geophysical Fluid Dynamics Lab (head Dr P.S. Petrov) of the V.I.Il’ichev Pacific Oceanological Institute (POI) in collaboration with Matrosov Institute for System Dynamics and Control Theory (ISDCT) and Far Eastern Federal University (FEFU)

 

AMPLE team:

  • Andrey G. Tyshchenko, engineer, GFD lab, POI
  • Oleg S. Zaikin, leading researcher, ISDCT
  • Mikhail A. Sorokin, Ms student, FEFU
