Accurate salt interpretation involves an integration of geology and geophysics. In the practice of salt interpretation and model building in depth imaging, we see two problems that could happen: exclusive geophysical interpretation without geological input and insufficient geological interpretation without understanding how the geophysical data are processed and without evaluating the limit and...

Sequential Bayesian techniques enable tracking of evolving geophysical parameters via sequential observations. They provide a formulation in which the geophysical parameters that characterize dynamic, nonstationary processes are continuously estimated as new data become available. This is done by using prediction from previous estimates of geophysical parameters, updates stemming from physical ...

Rock physics models allow establishing a physical-mathematical relation between rock and fluid properties and geophysical attributes. In this study, we propose to apply rock physics models to a geophysical dataset measured at two well locations near the proposed Snake River Plain FORGE site in eastern Idaho. The potential target is a rhyolite layer, which occurs between 2,000 and 3,000 m. The a...

[1] There is increasing interest in the use of multiple measurement types, including indirect (geophysical) methods, to constrain hydrologic interpretations. To date, most examples integrating geophysical measurements in hydrology have followed a three‐step, uncoupled inverse approach. This approach begins with independent geophysical inversion to infer the spatial and/or temporal distribution ...

Details of Earth’s shallow subsurface—a key component of the critical zone (CZ)—are largely obscured because making direct observations with sufficient density to capture natural characteristic spatial variability in physical properties is difficult. Yet this inaccessible region of the CZ is fundamental to processes that support ecosystems, society, and the environment. Geophysical methods prov...

Both geophysical and geochemical techniques contribute to our understanding of the complex nature of the Earth’s mantle, but the two sources of information provide very different viewpoints. Most geophysical evidence provides an instantaneous snapshot of current structure, whilst geochemical evidence has much more information on age. Further, geophysical probes are naturally integrative since t...

Recent developments in geophysical data analysis suggest that in addition to a multi-method approach, “data fusion” techniques can offer meaningful insights into archaeological features, as well as allow for researchers to establish patterns between multivariate data sets that might otherwise go unnoticed. Extensive and intensive geophysical prospection has been employed at the site of Portus i...
