🎯 Role Definition

A Geophysical Data Analyst is a highly specialized professional at the intersection of geoscience, physics, and data science. The core purpose of this role is to process, analyze, and interpret complex geophysical datasets—primarily seismic, but also gravity, magnetic, and electromagnetic data—to create detailed models and images of the Earth's subsurface. This individual is pivotal in identifying and characterizing geological structures, stratigraphy, and rock properties, directly supporting critical decisions in energy exploration, reservoir management, carbon capture and storage (CCS), geothermal energy, and civil engineering projects. They are the storytellers of the subsurface, translating vast streams of numerical data into a coherent geological narrative that guides significant investment and operational strategies.
