Re: software for MASW analysis

Hi Maybe you should take a look at Geopsy, I'm not sure how good it is on its results, but it has a tutorial to process MASW. I usually works with PARKSEIS. You can download the software right from their page. I'll give you a link of the tutorial to MASW http://www.geopsy.org/wiki/index.php/Active_...

Re: Best GPR for underground utility locating

What is HDR? High dynamic range. Basically it means it can have better effective penetration depth by reducing random noises through oversampling and stacking. I believe Mala, GSSI and Sensors&Software are all using the same techniques now (although they might have different names for it) for their...

I recommend Mala Easy Locator Pro Widerange HDR. This is a dual frequency system with the HDR technology. The two center frequencies are appropriate for underground utility locating. GSSI had a dual frequency system, but in my opinion they chose the wrong center frequencies. It's before HDR tech any...

Re: How realistic are the hopes of oil workers in the geothermal opportunity?

The United States is sitting probably the biggest geothermal reservoir in the world around Yellowstone National Park. If it blows up, half of the continent might be put into misery. But apparently it's off limits for development.

Sometimes you can see pretty neat GPR profiles. These two profiles are perpendicular to each other in the same survey area.

Re: Statics corrections in reflection seismic processing

I always love color-coded contour maps such as those provided by refraction tomography. The software we use probably are not as powerful as those used in oil and gas industry, but are convenient for us to use for smaller scale engineering surveys:

Re: Statics corrections in reflection seismic processing

Aha! It makes sense. The refraction method is easier in terms of data processing, especially when you don't have the computing power we have now. So it actually can be used first.

Re: Statics corrections in reflection seismic processing

I didn't know seismic refraction surveys can be useful for seismic reflection data processing, very interesting. We use seismic refraction in engineering field very often. Was the seismic refraction method invented for helping seismic reflection data processing in the beginning?

Re: Geovizer.ru help

Geovizer is not popular in the states. You probably have a much better chance to find a Geonics EM31 or EM38. It's not cheap, but I don't know how much Geovizer costs and what your friend's budget is. https://www.rtclark.com/product/geonics-em31-mk2-ground-conductivity-meter/ https://www.rtclark.com...

There is also a disconnection between geophysics software and their users in near surface geophysics.

Re: Geovizer.ru help

I never used it. But I took a look at their website. It should be a frequency domain conductivity meter, like Geonics EM31. Since it is multi frequency, actually it’s more like GSSI EMP 400, which was discontinued.

Re: What is the difference between GEOLOGIST & GEOPHYSICIST?

I often hear geophysicists complain that geologists take their jobs, but not the other way around. Maybe geophysicists are really geeks and hate to see geologists doing their jobs with minimal understaning about math/physics behind it. :lol:

I am surprised that Texas is far from the worst state in terms of unemployment rate. I thought Texas would be hit harder due to the oil price.
