Learning outcomes

After successfull completion of the course the student is expected to be able to

• give a detailed description of how the Earth's gravity and magnetic fields can be measured and analysed
• derive methods for mapping structures and processes in the Earth's interior related to the gravity and magnetic fields
• apply the techniques på global problems as well as on regional and local applicaitons.

Content

Description of the Earth's gravity and magnetic

potential fields in local and global coordinates.

The Earth's gravity field, the geoid and the shape

of the Earth. The tidal gravity field. Gravity

fields and density distribution in the Earth's

interior. Isostasy. Methods for measuring gravity.

Calculation and interpretation of gravity anomalies.

Rock densities. Origin of the geomagnetic field and

its variation in time and space. Geomagnetic

measuring techniques. Magnetometric interpretation.

Rock magnetism and paleomagnetics. Numerical

processing of potential field data: corrections,

reductions, transformations, model calculations

and interpretation methods. Studies of the gravity

and magnetic fields of other planets.
