Probabilistic estimation of merchant ship source levels in an uncertain shallow-water environment

Tollefsen, Dag; Hodgkiss, William S.; Dosso, Stan E.; Bonnel, Julien; Knobles, David P. (2021-11-13)

The estimation of ship source levels (SSLs) in shallow-water environments can be complicated by sound interaction with the seabed. Uncertainty in seabed properties influences SSL estimates, and it is of interest to mitigate ...
Ship-of-opportunity noise inversions for geoacoustic profiles of a layered mud-sand seabed

Tollefsen, Dag; Dosso, Stan E.; Knobles, David P. (2019-04-30)

This paper considers the use of broadband noise from a ship-of-opportunity in statistical inference for estimating geoacoustic parameters of a layered mud-sand seabed model via trans-dimensional (trans-D) Bayesian matched-field ...
