• To give a short introduction in Solid Earth Physics and the structure of the Earth.
• To give a basic knowledge in geophysical methods for exploration and environmental studies.
• To give the students the tools for suggesting suitable geophysical methods in solving exploration and environmental problems.

Seismology-seismic profiling: The different types of seismic waves, reflection and refraction seismics. The structure of the Earth. Interpretation of seismic refraction data. The correlation between elastic properties of a material and P-, S- wave velocities.
The magnetic field of the Earth, magnetometry: The Earth magnetic field, magnetic properties of rocks and unconsolidated sediments. Measuring methods and presentation of data. Exploration for mineral resouces.
The gravity of the Earth, gravimetry: The Earth gravity field, density of rocks and unconsolidated sediments. Corrections of gravity data and the calculation of Bouguer anomalies. Gravity in exploration
Electric and electromagnetic methods: Electric methods based on natural and artificial currents. Electric sounding and mapping. Electric conductivity of rocks and unconsolidated sediments. Examples from environmental studies, prospection for and planning of water resources, pollution of ground water. Electromagnetic field. Depth of penetration. Electromagnetic methods. Examples of application in exploration. Ground Penetrating Radar. Dielectric constants of rocks and unconsolidated sediments. Examples in environmental studies. Bore hole logging, electric magnetic susceptibiliy, sonic, density, neutron, gamma. Exploration, exaples from logging.

The teaching will be as lectures, laboratory and field training. Participation in laboratory and field training is compulsary. The lectures will be focused on basic theory and applications. The laboratory and field training will be directed on laboratory and field instrumental training, field measurements and data processing.

Written examination with differentiated degrees will be arranged at the end of the teaching period. The examination will include theory as well as problem solving.
Students who have failed an examination on five occasions will not be allowed further resits.
