Hi everyone, I am 4th year student working a project using geophones to measure ice thicknes. Is there a special method to layout the geophones to get an accurate profile an induced vibration? The purposal is to generate an acoustic pulse through possibly several kilometers of ice and have the geophones detect this pulse and derive the ice thickness. Would anyone have suggestions on a detonation mechanism? I've heard people use 1 kg of dynamite for 1 km of ice. As you can see, I am not too familiar with geophones but I do know they work like an accelerator. If anyone knows of a good book, please suggest it because none of our group members are geology people. Thanks alot for your time.
