The bathymetry is the most superficial layer of the Earth?s crust on which it is possible to perform direct measurements. However, it is also well known that water covers more than 70% of the Earth?s surface, so an enormous expenditure of acquisition cam...

In Mexico, agriculture in semi-arid regions is highly dependent on groundwater resources, where most of the aquifers? characterization is a pending task. In particular, the depth to the basement is unknown for most of the Mexican territory. Hence, the de...

To solve the inverse gravimetric problem, i.e., to estimate the mass density distribution that generates a certain gravitational field, at local or regional scale, several parameters have to be defined such as the dimension of the 3D region to be conside...
