Abstract : A comparison of a measured data set with five different model predictions is presented. Three of the predictions use the Low Frequency Bottom Loss model for the area, one prediction uses a geoacoustic model, and one (pure cylindrical spreading) assumes no bottom loss. All five predictions agree with the measured data well, with root-mean-square error under 2.5 dB. The models using bottom loss follow the trend better than cylindrical spreading.
