Geophysics is the study of the Earth, including its composition, structure, tectonic plates, earthquakes, and natural hazards. A geophysicist conducts seismic surveys using trucks with vibroseis or geophones to record energy reflections from geological boundaries below the surface. They process and interpret the seismic data using computer technology and visualization to learn about subsurface structures like ancient reefs. A geophysicist's work also includes collecting aeromagnetic and gravity data, finding water resources, and conducting archaeological and Arctic surveys. Geophysics students gain experience through field trips and field schools. Technologists assist with data management. Geophysicists and technologists are employed in engineering, the petroleum industry, mining,
