Fall 2009
Logistic and economic constraints often dictate the spatial sampling of a seismic survey. The process of acquisition records a finite number of spatial samples of the continuous wave field. The latter leads to a regular or irregular distribution of seismograms. Seismic reconstruction methods are...

The reflection seismic experiment results in a measurement(reflection seismic data) of the seismic wavefield. The linear Born approximation to the seismic wavefield leads to a forward modelling operator that we use to approximate reflection seismic data in terms of a scattering potential. We...

Human activities have profoundly altered the biogeochemical cycle of many elements including mercury (Hg). Since ~1850 AD, industrial processes are suggested to have led to a 3-fold increase in Hg deposition above natural, pre-industrial levels. Despite extensive historical evidence for...

Landslides have occurred throughout the Holocene geologic epoch and they continue to occur in the Peace River Lowlands of Alberta and British Columbia. This study was conducted to provide an understanding of the processes and extents of one such landslide situated on a major slope at the Town of...

Osteoporosis is a bone disease characterized by the degradation of mechanical competence and support of the skeleton, leading to fracture risk of the wrist, vertebrae, and hip. The disease is due to major decrease of mass and deterioration of micro-structure of bone tissues. In this study, bone...

Sparsity and Group Sparsity Constrained Inversion for Spectral Decomposition of Seismic Data
DownloadSpring 2012
Local time-frequency analysis, also known as spectral decomposition, allows for a more detailed interpretation of time-series by providing the evolution of the frequency spectrum through time and has proven to be a useful seismic attribute for exercises such as reservoir characterization. This...

Electrical Resistivity Structure of the Altiplano-Puna Magma Body and Volcan Uturuncu from Magnetotelluric Data
DownloadFall 2015
An intense episode of silicic volcanism in the Southern Altiplano over the past ten million years has created a major volcanic province in the Central Andes known as the Altiplano-Puna Volcanic Complex (APVC). Geophysical evidence indicates that magma is still present in a large mid-crustal...

Three-Dimensional Electromagnetic Imaging of Porphyry Copper Deposits with MT and ZTEM Data
DownloadFall 2015
This thesis investigates the use of the airborne Z-Axis Tipper Electromagnetic (ZTEM) and ground-based magnetotelluric (MT) exploration techniques to image electrical resistivity contrasts associated with porphyry copper deposits. These techniques were individually used to construct...

Acoustic and elastic least-squares two-way wave equation migration with exact adjoint operator
DownloadSpring 2017
A major problem in exploration seismology entails estimating subsurface structures and properties via linearized inversion. The problem is often called ''least-squares migration" where seismic imaging is posed as an iterative least-squares problem. The iterative solution employs the method of...

A Novel Method of Measuring Refractory Black Carbon Mass and Number Distributions by Inversion of CPMA-SP2 Data
DownloadFall 2017
A new method of examining mass and number distributions of nanoscale refractive black carbon (rBC) particles has been developed. This method will be useful for atmospheric scientists conducting semi-continuous measurement of atmospheric rBC. The new method uses a Centrifugal Particle Mass...
