Getting experience with Mobile ed

While in the summer log cabin as hillbilly, I had to spend some cold days inside. So I decided to go through my mobile eds. I don't usually buy them but I have got some nevertheless.

Generally they are good quality: the content, the sound, and the video are good. The content of the videos don't go very deep, but they often provide a good 3D view/experience for me.

Loading the videos works quite well through the mobile 4G internet, although I am in a sparsely populated area (perhaps half mile between the houses in average) and the base stations are far away.

Sometimes there are new and interesting information. But today I heard about "ground penetrating sonar" for the first time in my life. I know there are seismic methods etc. It is in Craig Evans' NT 307, in the chapter describing scientific tools. I just wonder whether he was talking about the "ground penetrating radar", and got an acoustic typo. I appreciate Craig very much and he has visited Finland in 2015. But I think it would be good to check this to keep the mobile eds in the high level content.

You're the expert. But just scanning the web, seems GPS can do soil-level penetration, especially if the soil is moist. Cemeteries and burial sites (one in Norway; buried viking ship).

Using my trusty Logos (always a surprise), sonar shows up as a goldsmith in caste systems. So. (I hope I'm not offending anyone). But a ground penetrating sonar would be looking for gold (in Logos).

Well, I tried phrase "ground penetrating sonar" in Google earlier, and it did not provide any exact results. GPS leads to global positioning system.

I am pretty sure that Sonar will penetrate the ground, and provide information, but the "ground penetrating sonar" is not a common technical term. An extract from text based on the video speech (in the section "Other Enhancements and Analyses") points to hard and dry contexts:

"Ground-penetrating sonar has exposed to us the presence of disturbances beneath the ground, including cavities and caverns and caves and so on. Ground-penetrating sonar has been used in examining the very ground, the marl terrace on which the ruins at Qumran are located. And this work has led to the discovery of some disturbances beneath the ground, including the inadvertent discovery of a very important ostracon that is a list of property that may very well be a long-lost record of property given to the Qumran community there at Wadi Qumran."

I don't see any gpr or gps at Qumran. Quite a bit cemeteries.

There's several patents on gps: https://patents.google.com/patent/US5719823A/en

But I assume maybe a cheap alternative to gpr and near-surface only? Qumran cemetery had only limited excavation.

Ok, thanks for the link, Denise!

It makes sense to have a good title, like "ground penetrating sonar" in a patent application. Otherwise archeologists seem to use "sonar" currently. The video is from 2014.

The ground penetrating radar does not work in sea water or salty ground. Thus it makes sense to use a sonar in in the vicinity of the Dead sea.
