Geoacoustic inversion via trans-dimensional sampling over seabed and error models

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


This paper develops an efficient Bayesian sampling approach to geoacoustic scattering and reflection inversion based on trans-dimensional (trans-D) sampling over both the seabed model (number of sediment layers) and error model (autoregressive order to represent residual correlation). Sampling is carried out using a population of interacting Markov chains employing a range of sampling temperatures (parallel tempering). The approach is applied to both simulated and measured data. The advantages...[Show more]
