Let’s continue with our eight-part series where we’ll be recommending some further reading for those of you who want to learn more about resistivity, induced polarization, and more in the realm of geophysics. The trio of suggestions that we’ve listed below cover geophysical inversion, induced polarization, and matrix computations. Reading any (or all) of these should help to broaden your knowledge and bolster your confidence going into your next geophysical survey.
And in case you missed them, here are the previous suggestions in this series:
...Welcome back to our eight-part series where we’ll be recommending some further reading for those of you who want to learn more about resistivity, induced polarization, and more. We hope our suggestions so far have been helpful in broadening your understanding of these topics. And if not—well—the third time's the charm!

Welcome to this eight-part series where we’ll be recommending some further reading for those of you who want to learn more about resistivity, induced polarization, and more. We’ve used the publications in this list time and time again—and we want to share that knowledge with you!
This won’t be a definitive list (since there is a lot of great literature out there), but the publications we’ve chosen should help to give you a better understanding of these topics—which can only improve your future geophysical surveys. We’ll be linking to the...
We're beyond excited to announce our innovative new system that will change the way that you do marine surveys! With our 3rd Generation SuperSting™ Marine System, you can now perform marine surveys easier and at least 30% faster.

In our previous article, The 7 Most Common Signs of Sinkholes, we went over some visual cues to spot sinkholes before total collapse. Now, let’s get a little more hands-on and show you how you can actually test for sinkholes before they occur.
So let’s say you suspect that your site may have an underground void (maybe you see depressions in the ground or cracks in your foundation). If you see any signs of a sinkhole, you’ll have to test the area to see what kind of subsidence or sinkhole you’...
Well, it’s not every day that we get to use a headline like that—but it’s true! Last year in China, a customer of ours—China Geological Survey (CGS)—worked with The University of Electronic Science and Technology, and Laurel Technologies for an extraordinary project. The joint research team was tasked to conduct an underwater and shoreline geophysical exploration of the Shen Yin site in Jiangkou after a few artifacts were discovered by locals near the shores of a river. These findings quickly grew into a high-profile...
So often, after someone asks "What is groundwater?", the next immediete question is "How do I find groundwater?". Well today, we're teaching you the best way we know how to find groundwater—Electrical Resistivity Imaging. First things first, we have to remember where groundwater can be found. As you know from our Groundwater Education Series, an aquifer is a natural underground reservoir of water that can be used as a water source. There are few geological formations in the ground...
Resistivity surveys come in a few flavors—one-dimensional (1D), two-dimensional (2D), three-dimension (3D), and technically even four-dimensional (4D), though we’ll save 4D for a future post. Let’s focus on 1D, 2D, and 3D for now. If you’re new to the world of Electrical Resistivity, it can be difficult to understand what’s the best type of survey for your needs. In this post, we’ll cover how these three types compare—and the type of survey that we think is the best of the bunch—3D surveys.
First, let’s break down how these different surveys stack up...
It’s time again for another entry in our ongoing groundwater series. Today, we’re talking about the more dangerous aspect of groundwater. Specifically, groundwater pollution and contamination. Unfortunately, there are far too many ways for us to cover in one post—but we can always revisit this topic in the future.
So, how does...
