Imaging polar and dipolar sources of geophysical anomalies by probability tomography. Part I: theory and synthetic examples [PDF]
Progress In Electromagnetics Research, vol. 87, 63-88, 2008, 2006 We develop the theory of a generalized probability tomography method to image source poles and dipoles of a geophysical vector or scalar field dataset. The purpose of the new generalized method is to improve the resolution power of buried geophysical targets, using probability as a suitable paradigm allowing all possible equivalent solution to be ...

Archaeological Prospection, EarlyView.ABSTRACT This paper presents the interdisciplinary investigation (archaeology, geochemistry, history) of a medieval silver and lead production site located in southern France, in the Minier valley (Occitanie, Aveyron, Le‐Viala‐du‐Tarn). In order to identify the production sites, in situ geochemical surveys were carried out using a portable X‐ray ...

Archaeological Prospection, EarlyView.ABSTRACT There is a common agreement among archaeologists that assessing visibility in the field is essential to measure the accuracy of their observations. Archaeologists widely expect that low visibility negatively impacts the recovery rate of artefacts and sites during field‐walking surveys.

Constraining the shape of a gravity anomalous body using reversible jump Markov chain Monte Carlo [PDF]
Geophysical Journal International. (2010) 180, 1067-1079, 2010 Typical geophysical inversion problems are ill-posed, non-linear and non-unique. Sometimes the problem is trans-dimensional, where the number of unknown parameters is one of the unknowns, which makes the inverse problem even more challenging. Detecting the shape of a geophysical object underneath the earth surface from gravity anomaly is one of such ...

Archaeological Prospection, EarlyView.ABSTRACT Electrical resistivity tomography (ERT) is nowadays widely used in archaeological prospection. This study deals with an approach to make ERT more time‐efficient and flexible. It is based on calculating arbitrary 4‐point configurations by superposition of multiple pole–pole measurements.

Signature of helium rain and dilute cores in Jupiter's interior from empirical equations of state
Earth and Planetary Physics, 2020 Measurements of Jupiter's gravity field by Juno have been acquired with unprecedented precision, but uncertainties in the planet’s hydrogen–helium equation of state (EOS) and the hydrogen–helium phase separation have meant that differences remain in the ...
