Geophysicist
Geophysicists study the structure and composition of zones
below the surface of the earth by taking measurements with
techniques such as seismic, gravity, magnetic and electrical
methods.
A geophysicist may perform the following tasks:
- supervise collection and processing of seismic data for
petroleum exploration and interpret and map prospects on
which to drill a well
- plan, conduct and interpret geophysical surveys in
exploring for mineral commodities such as gold, base metals,
diamonds and coal using various electrical techniques,
magnetic or gravity surveys
- design, develop and operate computer systems and
software for processing and interpreting geophysical data
sets
- plan, conduct and interpret geophysical surveys to
locate and estimate quantities of recoverable groundwater
reserves, the distribution and extent of salinity in
agricultural areas or the extent of pollution in the ground
or atmosphere
- carry out geophysical surveys of areas prior to the
construction of major engineering structures such as dams,
bridges or roadworks
- study earthquakes and earthquake risk, time variations
and the distribution of the earth's magnetic and gravity
fields, the physics of rocks and minerals and fluid dynamics
of molten rocks (magmas), oceans and atmosphere
- research new methods and instrumentation
- develop instrumentation for taking physical measurements
in surveys including gravity meters, magnetometers,
electrical, electromagnetic and radar transmitters and
receivers, seismic recorders and radiometric systems
- develop mathematical models as an aid to interpreting
geophysical survey results.
Geophysicists often work as part of a team of
geoscientists. Some carry out field work which may involve a
lot of travel, often to remote areas.
The two main divisions of geophysics are exploration
geophysics which deals with the search for the earth's
resources, and global geophysics which uses the same
techniques to study the earth as a whole and study
earthquakes, magnetic fields, etc. Geophysicists often
specialise in areas such as seismology and seismic
interpretation, borehole geophysics, mineral exploration,
engineering geophysics, environmental or groundwater
geophysics, or computer processing and software development.
