[EN]Wide-angle seismic reflection/refraction (WA) surveys provide
data that can be modeled to obtain lithospheric-scale P-wave velocity (VP) models. The interpretation of these datasets is often performed as a laborious and time-consuming trial-and-error procedure,
in which the relevant model parameters (layer thickness and VP) are
manually adjusted until the forward modeling matches the observed travel-times. In this work, we present a fully automatic iterative
nonlinear approach to invert WA datasets based on the simulated
annealing technique. We test our proposed approach with data from
the MARCONI-3 WA profile (southern Bay of Biscay) and compare
the outcome with an existing detailed interpretation, discussing the
similarities between the two models and the agreement between our
model and the observed travel-times.
