Trans-dimensional joint inversion of seabed scattering and reflection data

Steininger, Gavin; Dettmer, Jan; Dosso, S.E.; Holland, Charles W.


This paper examines joint inversion of acoustic scattering and reflection data to resolve seabed interface roughness parameters (spectral strength, exponent, and cutoff) and geoacoustic profiles. Trans-dimensional (trans-D) Bayesian sampling is applied with both the number of sediment layers and the order (zeroth or first) of auto-regressive parameters in the error model treated as unknowns. A prior distribution that allows fluid sediment layers over an elastic basement in a trans-D inversion...[Show more]
