1. Inversion and Joint Inversion of Electromagnetic and Potential Field Data
Sammanfattning : In this thesis, four inversion problems of different scale and difficulty are solved. Two of them are electromagnetic inverse problems. Two more are joint inversion problems of potential field data and other types of data. LÄS MER
2. Joint inversion and integration of multiple geophysical data for improved models of near-surface structures
Sammanfattning : Geophysical methods are non-invasive and allow an effective way of understanding subsurface structures and their physical properties. One of the main challenges is the often non-uniqueness of the geophysical models and that several different models can explain a dataset to an agreeable fit. LÄS MER
3. Investigating Time-Varying Processes Using Seismicity and Time-Dependent Tomography
Sammanfattning : Our global society is affected by, and makes use of, many time-varying processes. Processes related to geothermal energy and CO2 sequestration can help mitigate climate change and reduce the number of premature deaths (millions annually) due to air pollution from fossil fuels.

4. New Techniques for Estimation of Source Parameters : Applications to Airborne Gravity and Pseudo-Gravity Gradient Tensors
Sammanfattning : Gravity gradient tensor (GGT) data contains the second derivatives of the Earth’s gravitational potential in three orthogonal directions. GGT data can be measured either using land, airborne, marine or space platforms. LÄS MER
5. On Satellite Gravity Gradiometry
Sammanfattning : .... LÄS MER
