    • Geoacoustic modeling of the seabed at higher frequencies 

      Stoll, Robert D.; Bautista, Edgar O. (NATO. SACLANTCEN, 1997)
      In propagation at higher frequencies, local fluid motion in "hidden coordinate" systems and local discontinuities due to gas bubbles and bioturbation have a perturbing effect on the wave field. To model these effects, a ...
    • Time domain finite difference methods for range dependent Biot media 

      Stephen, Ralph (NATO. SACLANTCEN, 1997)
      The physics of sound propagation in saturated, porous (Biot) media differs from propagation in fluids and elastic/anelastic solids because of the existence of a second compressional wave, the "slow" wave. Many environments ...
