It has always been necessary for archaeologists to ‘dig’ for information. The problem with this is that digging destroys the site. But, a relatively new science, geophysics, can provide ways of ‘looking underground’ without the need to dig.

The big contribution of geophysics to world might be that it ends altogether the need to dig for information, and not just in archaeology. Geophysics can also help Gardai find bodies buried in a large suspected area, or illegal dump sites.
