Geophysics

Geophysics is the branch of the Earth sciences which is studies the physical pehenomena which are relevant to the structure, physical conditions and evolutionary history of the Earth as a whole.

Topics of interest include:

• Seismology - the study of earthquakes and the shock waves that they produce
• Gravity - the gravity field and rotation of the earth
• Magnetics - the magnetic field of the earth and how it varies in strength and orientation
• Temperature gradients and heat flow
• Electromagnetic effects
• Natural radioactivity
• Oceanography - the physical aspects of the world's seas and oceans
• Meteorology

Many of the techniques used in geophysics have commercial applications in geophysical prospecting for oil & gas, minerals and water.

Near-surface techniques have applications in archaeology and ennvironmental studies.
