Abstract

Bayesian MFI has been applied to low-frequency narrowband ship-noise recorded on a HLA deployed on the seafloor in shallow water. Seabed geoacoustic model parameter estimates compared well with results from inversion of controlled-source data and with prior geophysical data from the experiment site. Further research is in progress to simultaneously quantify uncertainties in source track and seabed geoacoustic parameters using a Bayesian approach.
