Generation and Analysis of Bottom Loss Upgrade Geoacoustic Parameters for Specific Locations in the Northeast Pacific.

Abstract

Naval Air Development Center (NADC) octave-averaged bottom loss data were used as the primary resource in the generation of Bottom Loss Upgrade Program (BLUP) geoacoustic parameter sets for specific locations in the Northeastern Pacific Ocean. A ray trace simulator of the NADC measurement and analysis procedure was developed and used to determine the BLUP parameters. The BLUP parameters and a comparison of simulated bottom loss to data for each location are presented. Deficiencies in the comparison at each location and the suitability of the BLUP parameter set for representing the acoustics of thin sediment areas are discussed. (Author)
