    • Analysis of broad-band echosounder data over a gassy seabed 

      Boyle, Frank A.; Chotiros, Nicholas P.; Pace, Nicholas G.; Bergem, Oddbjorn; Pouliquen, Eric (NATO. SACLANTCEN, 1997)
      Calibrated echosoundings from a well-characterized gassy seabed were examined. Acoustic reflection was significantly higher than expected. It is hypothesized that gas bubbles are responsible. Anomalously high levels of ...

    • The effect source movements on shallow water bottom backscatter 

      Bergem, Oddbjorn; Pouliquen, Eric; Pace, Nicholas G. (NATO. SACLANTCEN, 1997)
      The time-evolution model BORIS is used to study the effects of source movements on bottom backscatter. Changes in the backscattend time domain signals as functions of source depth, position and incident angles are simulated ...
