Geologist Career Guide

What is a geologist?

A geologist is a scientist who studies solid and liquid matter that constitutes the Earth and the processes and history that have shaped it. These scientists usually study terrestrial planets, soil, rocks, and frozen water. They’re significantly valuable within businesses, especially those involved in natural resource extraction and environmental consulting, as their understanding of the Earth’s processes can help companies safely execute their operations and align them with environmental regulations.

They play a critical role because their findings can significantly influence not just commercial activities but also society at large. For instance, in the oil industry, they play an integral role in exploring and producing petroleum. Their services are equally critical in environmental projects where they help design restoration projects or devise mitigation measures against natural hazards. They offer knowledge that helps decipher Earth’s complex processes and inform sustainable human practices on Earth.

Duties and responsibilities

The specific tasks of a geologist can vary depending on the area of expertise. Generally, they’re responsible for collecting samples and data from the field, conducting laboratory tests, analyzing geological data using computer software, and interpreting the data to establish practical applications such as exploring natural resources.

These scientists also contribute to environmental conservation efforts by determining the impact of human activities on the Earth and its resources. They define remedial actions and help forecast future scenarios to guide strategic planning. They also conduct research, publish their findings in scientific journals, and contribute to the development of science education.

Work environment

Geologists are often required to split their time between the field, labs, and office environments. Fieldwork can involve traveling to remote locations and working in challenging conditions depending on the terrain and weather. They typically collect samples, make observations, and conduct tests in the field.

In the office and laboratories, they analyze the collected data and samples, create reports, present their findings, and engage in project planning. Depending on the specifics of a role, traveling and performing physically demanding tasks outdoors may be integral parts of the job.

Typical work hours

Most geologists work full-time and typically work a standard 40-hour per week. However, the nature of their work means that there may be periods of longer hours, especially when they are conducting field studies or when a project demands more time for completion.

Fieldwork may also require them to stay away from home for extended periods, sometimes in remote locations, making for unusual work schedules. While they mostly adhere to regular work hours, a degree of flexibility may be needed in this profession.
