However, the two methods are related as the results of deterministic models is the average of all the possible non-unique solutions of stochastic methods. [3] Since seismic linear inversion is a deterministic inversion method, the stochastic method will not be discussed beyond this point. Figure 1: Linear Seismic Inversion Flow Chart
Inverse transform sampling (also known as inversion sampling, the inverse probability integral transform, the inverse transformation method, or the Smirnov transform) is a basic method for pseudo-random number sampling, i.e., for generating sample numbers at random from any probability distribution given its cumulative distribution function.
Simultaneous Inversion (SI) is a pre-stack method that uses multiple offset or angle seismic sub-stacks and their associated wavelets as input; it generates P-impedance, S-impedance and density as outputs (although the density output resolution is rarely as high as the impedances). This helps improve discrimination between lithology, porosity ...
A 4,000-year-old timber circle on a Norfolk beach dubbed the “Seahenge” was built after a period of extreme climate degradation at the close of the third millennium BC, a new study has found ...
Seahenge, also known as Holme I, was a prehistoric monument located in the village of Holme-next-the-Sea, near Old Hunstanton in the English county of Norfolk. A timber circle with an upturned tree root in the centre, Seahenge, along with the nearby timber circle Holme II, was built in the spring-summer of 2049 BC, during the early Bronze Age ...
President Donald Trump’s offer to most federal employees to resign now and be paid through September stunned the workers who received it – angering some, confusing many and raising questions ...

Surface-wave inversion is the method by which elastic properties, density, and thickness of layers in the subsurface are obtained through analysis of surface-wave dispersion. [2] The entire inversion process requires the gathering of seismic data, the creation of dispersion curves, and finally the inference of subsurface properties.
