Geophysicist: If Your Geography is Good, Try Out A Career As A Geophysicist! Find Out How!
The interpretation of messages from the earth?s interior demands all the resources of ordinary physics and of extraordinary mathematics. The geophysicist is of a noble company, all of whom are reading messages from the untouchable reality of things. The inwardness of things?atoms, crystals, mountains, planets, stars, nebulas, universes?is the quarry of these hunters of genius and Promethean boldness.
WHAT IS GEOPHYSICS?
Geophysics is a subject of natural science concerned with the physical processes and physical properties of the Earth and its surrounding space environment, and the use of quantitative methods for their analysis. The term geophysics sometimes refers only to the geological applications: Earth's shape; its gravitational and magnetic fields; its internal structure and composition; its dynamics and their surface expression in plate tectonics, the generation of magmas, volcanism and rock formation. However, modern geophysics organizations use a broader definition that includes the water cycle including snow and ice; fluid dynamics of the oceans and the atmosphere; electricity and magnetism in the ionosphere and magnetosphere and solar-terrestrial relations; and analogous problems associated with the Moon and other planets. Geophysics is applied to societal needs, such as mineral resources, mitigation of natural hazards and environmental protection. In Exploration Geophysics, Geophysical survey data are used to analyze potential petroleum reservoirs and mineral deposits, locate groundwater, find archaeological relics, determine the thickness of glaciers and soils, and assess sites for environmental remediation.
WHO IS GEOPHYSICIST?
A geophysicist is someone who studies the Earth using gravity, magnetic, electrical, and seismic methods. Some geophysicists spend most of their time outdoors studying various features of the Earth, and others spend most of their time indoors using computers for modeling and calculations. Some geophysicists use these methods to find oil, iron, copper, and many other minerals. Some evaluate earth properties for environmental hazards and evaluate areas for dams or construction sites. Research geophysicists study the internal structure and evolution of the earth, earthquakes, the ocean and other physical features using these methods.
WHAT ARE THE TYPES OF GEOPHSYICISTS?
Geophysics covers a broad range of earth science and offers a variety of options. This list includes some, but not all, of the divisions of geophysics:
- Marine geophysicists
- Petroleum geophysicists
- Mining geophysicists
- Environmental geophysicists
- Atmospheric physicist
- Gravity geophysicist
- Magnetic geophysicist
- Electromagnetic geophysicist
- Electrical geophysicist
- Exploration geophysicists
WHAT ARE THE JOB RESPONSIBILITIES OF A GEOPHYSICIST?
As a geophysicist, you'll need to:
- pre-plan projects before going on-site
- design data acquisition plans
- decide on suitable seismic measurement and data-processing techniques
- take equipment out to various locations around the world and deploy seismometers
- observe the reaction of recording equipment to detect irregularities
- use computers for data management, quality control, and communication between the office and field locations
- interpret and map 2D and 3D seismic data
- report on collected seismic data to the team, clients, senior managers or partners at meetings and presentations
- measure reservoir volumes
- assess potential oil and gas yield
- design, test, modify and repair seismic equipment
- adapt data collection procedures
- work closely with a small team of scientists and other staff who may be away in the field or offshore for several weeks at a time
- compile charts and reports
- write documentation and work logs
- provide a range of geophysical support and technical advice and guidance
- keep abreast of new and emerging technologies
- improve existing techniques in data acquisition and mathematical processing, as well as seek to develop new techniques and methods
- work within budget, resource and time constraints.
WHAT ARE THE EDUCATION AND TRAINING REQUIREMENTS?
To become a geophysicist you usually have to complete a degree in science with a major in geophysics, geoscience or a combination of geology and physics, preferably at the honours level. To get into these courses you usually need to gain your Senior Secondary Certificate of Education. Prerequisite subjects, or assumed knowledge, in one or more of English, mathematics, chemistry, physics, and biology are normally required. Universities have different prerequisites and some have flexible entry requirements. Contact the institutions you are interested in for more information.
WHAT IS THE SKILL SET NEEDED TO BE A GEOPHYSICIST?
- Good IT skills to process data and produce three-dimensional models of geophysical features
- Numerical skills
- Project management skills
- Analytical and problem-solving skills
- Flexibility and adaptability
- Attention to detail and the ability to record information accurately
- The ability to express ideas and findings clearly, both orally and in writing to produce reports and make presentations
- Team working skills
- The ability to work to deadlines and under pressure
- Desire to travel, as worldwide travel is a key feature of this career
- Commitment to continual learning.
You'll also need good color vision as the work may involve interpreting geological maps and differentiating between various rocks and minerals. A driving license and evidence of good health may be required for some postings. For overseas work, a second language is an advantage, as well as cultural awareness and communication skills.
