Subsurface specialists focus on exploring and analyzing underground conditions using geophysical and geological methods, often in resource extraction or environmental projects. Geotechnical engineers design foundations and assess soil stability for construction. While both roles involve subsurface data, subsurface professionals emphasize data collection and interpretation, whereas geotechnical engineers focus on applying that data to engineering solutions.
