Seismic data are inverted to estimate subsurface model parameters. We would like to address current challenges and directions in seismic data inversion and parameter estimation. Questions to address include inversion of non-ideal data, the influence of parametrization on the retrieval of velocity models, inversion of data in the absence of frequencies, and estimation methods for models with sharp discontinuities. Issues to discuss in this mini-symposium are of current importance. With the advent of algorithms for seismic full-waveform inversion, new problems have arisen, and a definite necessity for formulating new directions in seismic inversion and geophysical estimation theory.
