	abstract = {During this talk, I will explain how ideas from compressive sensing and big data can be used to reduce costs of seismic data acquisition and wave-equation based inversion. The key idea is to explore structure within the data by deliberately breaking this structure with randomized sampling, e.g., by randomizing source/receiver positions or by source encoding, followed by an optimization procedure that restores the structure and therefore recovers the fully sampled data. These techniques not only underpin recent advances in missing trace interpolation and simultaneous acquisition but they are also responsible for significant improvements in full-waveform inversion and reverse-time migration. We will illustrate these concepts using a variety of compelling examples on realistic synthetics and field data.},

	abstract = {Sparse signal recovery has been dominated by the basis pursuit denoise (BPDN) problem formulation for over a decade. In this paper, we propose an algorithm that outperforms BPDN in finding sparse solutions to underdetermined linear systems of equations at no additional computational cost. Our algorithm, called WSPGL1, is a modification of the spectral projected gradient for $\ell_1$ minimization (SPGL1) algorithm in which the sequence of LASSO subproblems are replaced by a sequence of weighted LASSO subproblems with constant weights applied to a support estimate. The support estimate is derived from the data and is updated at every iteration. The algorithm also modifies the Pareto curve at every iteration to reflect the new weighted $\ell_1$ minimization problem that is being solved. We demonstrate through extensive simulations that the sparse recovery performance of our algorithm is superior to that of $\ell_1$ minimization and approaches the recovery performance of iterative re-weighted $\ell_1$ (IRWL1) minimization of Cand{\`e}s, Wakin, and Boyd. Moreover, our algorithm has the computational cost of a single BPDN problem.},

	abstract = {The removal of coherent noise generated by surface waves in land based seismic is a prerequisite to imaging the subsurface. These surface waves, termed as ground roll, overlay important reflector information in both the t-x and f-k domains. Standard techniques of ground-roll removal commonly alter reflector information. We propose the use of the curvelet domain as a sparsifying transform in which to preform signal-separation techniques that preserves reflector information while increasing ground-roll removal. We look at how this method preforms on synthetic data for which we can build quantitative results and a real field data set.},

	abstract = {Accurate and adaptive noise removal is a critical part in seismic processing. Recent developments in signal separation methods have allowed a more flexible and accurate framework in which to perform ground roll and reflector separation. The use of a new Bayesian separation scheme developed at the SLIM group that contains control parameters to adjust for the uniqueness of specific problems is used. The sensitivity and variation of the control parameters is examined and this method is applied to synthetic and real data and the results are compared to previous methods.},
