SAGE - Summer of Applied Geophysical Experience

06/23/2026

Field geophysics is equal parts precision, patience, and progress.

This week at , the gravity group has been collecting data across the Valles Caldera, learning how subtle variations in Earth’s gravitational field can help reveal what lies beneath the surface.

In one field moment, students grouped together to form a human windshield around the gravity meter. It was a perfect example of what fieldwork really looks like: collaborating, adapting to conditions, and learning how careful measurements are made in real time.

As one SAGE student reflected from the field: “​​A lot of people get into geophysics because they’re really interested in Earth processes and they want to study them more. But the coolest part is that along the way, you end up becoming an expert camper, backpacker, computer scientist, electrical engineer, and a host of other disciplines. Along the way, you get a diversity of tools that help you study the Earth better. And that’s really cool.”

Field learning is in full swing at .

Each day, students break into focused groups for intensive, hands-on instruction in a range of geophysical methods. They’re learning not just how the tools work, but how to apply them in complex, real-world field conditions.

Here, the ERT and TEM group is using near-surface electromagnetic techniques to help resolve the geologic controls on the locations of fens in the Valles Caldera, while also mapping older, pre-caldera rocks that may be concealed beneath the sediments.

Collecting data across this landscape takes more than technical skill. It takes teamwork and persistence, especially when survey lines cross deep, muddy fens and the anastomosing channels of San Antonio Creek.

It’s exactly the kind of field experience that makes SAGE so valuable: students working side by side, applying geophysics to real geologic questions.

During the geology field trip, each stop provided important context for understanding the caldera’s physical properties, depositional history, and geologic structures that influence the geophysical data students will be analyzing throughout the program.

By combining direct field observations with geophysical imaging, students gain a deeper understanding of how surface geology and subsurface data work together.

isn’t just about collecting data, it’s about understanding the full story.

Students spent the day studying the fen in Valle Santa Rosa using electrical resistivity tomography (ERT) as part of their near-surface hydrology research.

But the surface tells its own story too.

In the fen, soft, saturated ground can trap animals, leaving behind bones that become part of the landscape over time. It’s a stark reminder of how dynamic, and sometimes unforgiving, these environments can be.

Research at SAGE means engaging with both the science and the reality of natural systems.

There’s nothing like learning geophysics in the field.

At Training Day, students went beyond theory—getting hands-on experience with a wide range of geophysical methods and instruments, guided by faculty experts.

From passive to active methods, it was a full immersion into how we actually see beneath the surface:

‣ Passive seismic with Akram Mostafanejad
‣ GPS systems with Beth Pratt-Situala
‣ Magnetotellurics (MT) with Jared Peacock and Paul Bedrosian
‣ Nodal and EM vibe active seismic with Mark Davidson
‣ Electrical Resistivity Tomography (ERT) with Paul Bedrosian
‣ Gravimetry with Tait Earney

Across each station, students aren’t just observing. They are setting up equipment, asking questions, and connecting data collection to real-world applications.

This is what SAGE is all about: Learning geophysics by doing geophysics.

is officially underway!

We kicked off the program in Los Alamos, New Mexico, USA with student introductions—sharing what we're excited about, what makes us a little nervous, and something others might not know about us.

This year's cohort is already proving to be an incredible group of individuals—including artists, musicians, a Red Cross disaster relief volunteer, an identical twin, and so much more.

We're excited to see how these unique experiences and perspectives come together over the coming weeks as students learn, collaborate, and grow through SAGE.

Welcome, Class of 2026!

What’s something that others may not know about you outside of geophysics? Share below in the comments.

At SAGE, we're using virtual learning spaces and collaborative whiteboards to get students ready for SAGE2026.

Teams contribute insights from their readings, capture "burning questions," and learn from faculty experts who respond based on their areas of expertise.

By revisiting key takeaways, answering outstanding questions, and connecting concepts from one session to the next, we're creating a continuous and interactive learning experience—one that helps students build deeper understanding and long-term success.

What burning questions do you have about geophysics? Comment below and let us know!

“I was immediately hooked.”

Eva Smith's path into geophysics didn’t start in the field. But once she got there, she never looked back.

From SAGE student to TA, instructor, and now 2026 camp manager, Eva’s journey reflects exactly what this program is about: curiosity, hands-on learning, and building a community around real-world science.

Her perspective is a reminder that meaningful learning also happens outside the classroom—where data is messy, problems are real, and discovery is shared.
