Seismic Soundoff

“Models are still the bread and butter in gravity and magnetics interpretation. Interpreters still have to condition the data properly, and that's half technical, half art.” Betty Johnson shares how her early career in gravity and magnetics grew from curiosity, hands‑on learning, and rapidly changing technology. She explains how potential field methods remain valuable for addressing energy, water, and climate challenges because they are affordable, scalable, and deeply rooted in Earth’s history. Her reflections underscore the importance of high-quality data, solid fundamentals, and ongoing learning. KEY TAKEAWAYS > Gravity and magnetics remain essential because they are cost‑effective, scalable, and useful across many energy and environmental applications. > Strong fundamentals in physics, geology, and modeling help interpreters make better decisions and collaborate across disciplines. > Good data, field experience, and continuous learning are critical for building a long and impactful geophysics career.
