A Unsolved Problems in Near Surface Geophysics

Click For Summary
The discussion centers on the challenges and potential advancements in near surface geophysics, particularly in exploration non-seismic methods. Despite the historical success of techniques like gravimetry and electromagnetics, there is skepticism about the emergence of new methods, with many professionals advocating for data integration and AI applications instead. The community is encouraged to explore unsolved problems in applied geophysics and consider whether new physics could lead to innovative measurement techniques. There is also interest in how advancements like autonomous drones and infrared technology could enhance data collection capabilities. Overall, the conversation highlights a tension between perceived stagnation in the field and the potential for future breakthroughs.

Hi everyone,

In the past when I was doing my undergrad in physics, I sometimes looked at this page for inspiration in research. However, I was unable to find a similar one for applied geophysics.

Currently, my area of research is exploration non-seismic geophysics, where the focus is on near surface phenomena. I know that in the past century, physics-based methods such as gravimetry, magnetics, time and frequency domain electromagnetics, self potential (SP) and Induced Polarization (IP) have been developed and successfully used for mineral exploration.However when I speak to people in the field, they argue that there is "no juice to be squeezed" and that the probability of a new method emerging is next to none. Apparently the current focus is rather on data integration from the existing methods, with most using AI for that purpose. It is hard to agree with this, since it could imply that applied geophysics is a dead-end subfield of physics.

My question to the community, particularly those who worked with or studied geophysics is the following: What are some unsolved problems in applied geophysics in your opinion? Is there potential for the emergence of a new physics-based method (e.g., IP and SP)? Or rather, is there potential for applying new physics to develop novel geophysical measurement techniques ?(e.g., building better magnetometers).

Very curious to know your thoughts!
Thanks.

How have the tools changed, and what will, or has now, become possible?

Numerical computation certainly supports seismic. But what other wave analysis is possible?

Autonomous drones can gather more data, faster, at lower cost.
What could they measure?
What about IR at night?

I'm setting up an analog power supply. I have the transformer bridge and filter capacitors so far. The transformer puts out 30 volts. I am currently using two parallel power transistors and a variable resistor to set the output. It also has a meter to monitor voltage. The question is this. How do I set up a single transistor to remove whats left of the ripple after the filter capacitors. It has to vary along with the control transistors to be constant in its ripple removing. The bases of the...
