Trans-dimensional matched-field geoacoustic inversion with hierarchical error models and interacting Markov chains

Dettmer, Jan; Dosso, S.E.


This paper develops a trans-dimensional approach to matched-field geoacoustic inversion, including interacting Markov chains to improve efficiency and an autoregressive model to account for correlated errors. The trans-dimensional approach and hierarchical seabed model allows inversion without assuming any particular parametrization by relaxing model specification to a range of plausible seabed models (e.g., in this case, the number of sediment layers is an unknown parameter). Data errors are...[Show more]
