    • Shear properties of ocean sediments determined from numerical modelling of Scholte wave data 

      Jensen, Finn B.; Schmidt, Henrik (NATO. SACLANTCEN, 1986/06)
      Recently it has become apparent that shear properties of ocean sediments are most easily determined from measured propagation characteristics of seismic interface waves. We use a newly developed numeri ca l model of wave ...
    • Statistical evaluation of 80 kHz shallow-water seafloor reverberation 

      Lyons, Anthony P.; Abraham, Douglas A.; Akal, Tuncay; Guerrini, Piero (NATO. SACLANTCEN, 1997)
      In this work a comparison is presented between 80 kHz reverberation statistics obtained at shallow water sites around Sardinia and Sicily. The data include measurements from several distinct bottom provinces, including ...
    • The optimum frequency of propagation in shallow-water environments 

      Jensen, Finn B.; Kuperman, William A. (NATO. SACLANTCEN, 1983/04)
      The optimum frequency of propagation in shallow water environments is the result of competing propagation and attenuation mechanisms at high and low frequencies. It is shown that the optimum frequency is strongly dependent ...
    • Time dependence of infrasonic ambient seafloor noise on a continental shelf 

      Akal, Tuncay; Barbagelata, Alessandro; Guidi, Guido; Snoek, Michael (NATO. SACLANTCEN, 1986/06)
      SACLANTCEN is conducting a long term programme of ambient noise measurements that cover the frequency band from 1 to 100 Hz. A sea-bed sensor consisting of three seismometers and a hydrophone has been deployed close to the ...
