c++ guy here, not sci guy, i have a question 06/18/15 (Thu) 15:23:15 No.2602

hey guys, not a sci guy by any means

have a question for you

is it possible to sonar or mri or any other way to image the earth?

i would love to do a huge sonar scan on this piece of dirt. i was thinking sonar but idk how that would work, and my budget is only like 100k (lol i dont think its doable)

why wouldnt a sonar work?

if you know how i can do it post the method and please post the supplies needed and a rough cost if you can

Doesn't sonar use sounds to create an image? So wouldn't the sound waves just bounce off of your dirt?

I think he means like an ultrasound

Op, just use an ultrasound.

Seismology is basically sonar, used in probing the entire earth (core) down to sub-km scales (fault lines). Used a lot in oil exploration.

For closer observations there are techniques like ground penetrating radar, electrical resistance, and electromagnetic conductivity. Mostly used in things like archeology.

You can also measure perturbations of satellite orbits to detect unevenness in the gravity field and map the density of the ground it's orbiting over.

Whole load of stuff basically.
