 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.Geophysics is a highly interdisciplinary subject, and geophysicists contribute to every area of the Earth sciences.
