    • Acoustic bottom reflectivity 

      Hastrup, Ole F. (NATO. SACLANTCEN, 1989/06)
      Acoustic reflectivity from the seafloor is often an important factor influencing the performance of ASW systems in different environments, such as in deep water when the bottom bounce paths are used, and in general in ...

    • Sound attenuation between 200 and 10,000 cps measured along single paths 

      Leroy, Claude C. (NATO. SACLANTCEN, 1965/09)
      In the deep Mediterranean basins, the water is perfectly isothermal below 400 m, and the deep refracted ray gives clear signals up to 40 km, with a spreading loss free from any frequency-dependent effect. Exploiting this ...
