This book describes the theory and practice of inverting seismic data for the subsurface rock
properties of the earth. The primary application is for inverting reflection and/or transmission …

I develop least-squares (LS)-based schemes to derive globally optimal spatial explicit
staggered-grid finite-difference (SGFD) coefficients of the first-order derivative over a given …

Conventional explicit finite-difference methods have difficulties in handling high-frequency
components due to strong numerical dispersions. One can reduce the numerical dispersions …

High-order staggered-grid finite-difference (SFD) schemes are preferred in elastic wave
simulation for geophysical problems because they decrease the accumulation of error from …

The staggered-grid finite-difference (FD) method is widely used in numerical simulation of
the wave equation. With stability conditions, grid dispersion often exists because of the …

The 2-D acoustic wave equation is commonly solved numerically by finite-difference (FD)
methods in which the accuracy of solution is significantly affected by the FD stencils. The …

Explicit finite-difference (FD) schemes are widely used in the seismic exploration field due to
their simplicity in implementation and low computational cost. However, they suffer from …

Full-waveform inversion (FWI) is a promising technique for recovering the earth models for
exploration geophysics and global seismology. FWI is generally formulated as the …

The density structure of firn has implications for hydrological and climate modelling, and ice-
shelf stability. The structure of firn can be evaluated from depth models of seismic velocity …
