Geophysicist
Is the scientist that applies the principles of physics to study the Earth and its processes. Traditionally speaking, earth scientists whose work is oriented to the study of the Earth using gravity, magnetic, electrical, and seismic methods are considered geophysicists. However, the term geophysicist can be extended to other scientists whose focus belong to fields such as atmospheric, oceanographic and ionospheric.
Geophysicists usually carry out surveys and have an active role in the acquisition, processing and modelling of the data from the field.
