- Understand the opportunities and limitations of non-seismic surveying techniques for hydrological, environmental, archaeological, and mineral exploration targets
- Design a field survey responding to a given problem
- Process, visualize, analyze, evaluate and report non-seismic survey datasets with competent use of state-of-the-art processing and modelling techniques and software packages
