Geophysicists study the physical composition and structure of the Earth, and measure and analyse forces such as earthquakes, magnetism or gravity that affect it. They also look for important minerals, including oil and gas, under the Earth’s surface.
A geophysicist often works in the broader field of geology, and the work may overlap with that of a geochemist and a geologist. See related article Geologist.
You could be:
studying the movement of tectonic plates in the Earth’s crust to predict and measure volcanic eruptions and earthquakes
doing surveys, using techniques such as seismic (vibration) testing, to find where there are natural resources such as coal, gas, oil or water
searching for sources of suitable rock for building roads, dams, tunnels and buildings or installing pipelines and cables
checking the condition of bedrock and subsoil, and working out the risk of landslide, subsidence or earthquake
using special equipment to identify changes in the soil and subsoil, which might show the presence of archaeological remains or early land use
collecting information to make geological maps, 3D computer models and databases
taking samples on site then testing and evaluating them in a laboratory
working with a team of other professionals, including geologists and engineers
analysing results and writing reports.
The figures below are only a guide. Actual pay rates may vary, depending on:
where you work
the size of the company or organisation you work for
the demand for the job.
The starting salaries for geophysicists in postdoctoral research posts are normally in the range £28,000 to £36,000 a year. University lecturers earn up to £50,000 a year. More senior research and teaching staff can earn over £60,000 a year.
In exploration work, new graduate salaries can range from £18,000 to £30,000 a year, depending on the industry you work in. With experience, this can rise to around £45,000. In senior positions the salary can be up to £75,000 and even more in the oil and gas industry. Salaries can be higher abroad.
You would work in a laboratory or office, using a computer for 3D modelling.
You would also spend time outside, onsite, taking samples and doing surveys. This may be on land, at sea or offshore on a rig.
If you work away from home, particularly at sea or offshore, you will probably have to share living and sleeping space with others.
You may have to work in difficult physical conditions and very hot or cold climates.
You would have to travel, possibly overseas.
A driving licence is useful.
You would work regular hours, but may have to work shifts including evenings or weekends, especially when you are onsite.
You would have to wear protective clothing, such as a safety helmet and boots, when you are onsite.
You would need an undergraduate degree in a relevant subject. The Universities of Aberdeen and Edinburgh offers degree programmes in geophysics. For entry you are likely to need 4-5 Highers including Maths and Physics plus English at least at National 5.
You may be accepted with a degree in a closely related subject such as physics, mathematics or geology. For entry you need 4 good Highers including Maths and Physics.
Most entrants have a postgraduate qualification in a specialist geological or geophysical subject. University of Aberdeen offer an MSc in Geophysics.
You need to be fit, to work onsite.
As a geophysicist you might work for the British Geological Survey, the British Antarctic Survey, oil or gas companies, mining or civil engineering firms. There are some jobs with specialist companies doing seismic surveys. There are also a limited number of jobs in archaeological work.
