How Ground Penetrating Radar is used in Archaeology

by admin in Uncategorized

With archaeology, sampling and excavating can be timely, costly and risky. One wrong move and archaeologists could damage or even destroy important structures or artifacts. For this, scientists need a non-destructive way to explore subsurface areas of the earth. This makes ground penetrating radar the perfect tool for discovering some of the earth’s hidden treasures. Let’s take a closer look at the role that GPR plays in the field of archeology. 

Ground penetrating radar survey is one method used in archaeological geophysics. Like other geophysical methods used in archaeology (and unlike excavation) it can locate artifacts and map features without the risk of damaging them. However, this method of non-destructive testing (NDT) not only locates and protects subsurface objects from being damaged, it also helps make excavation safer when actual digging does begin.Yet, this technology is not without its limitations when it comes to its archaeological applications. For one thing, many passes must be made over the same survey site in order to get the best understanding of what may lie beneath the surface. For another, because GPR data does not provide an outline of specific shapes, users must ultimately be guided by their experience and their best judgment to determine what found targets represent.

Objects Found Using GPR 

GPR can be used to find any number of precious articles buried by time with the goal of maintaining the integrity of these objects. Here is just a small sample of buried items this technology can reveal: 

  • Buried buildings and foundations
  • Forgotten infrastructure (trenches, waterways, cisterns, etc.)
  • Underground tunnels and voids
  • Buried military paraphernalia
  • Bones, human or otherwise
  • Lost graves, coffins, etc.
  • Other misc. artifacts

As you can see, GPR has many useful applications. It can help locate buried utility lines or it can help detect and preserve ancient relics which are by their very nature fragile and subject to being damaged. We are a non-destructive, non-invasive, subsurface imaging company that can produce detailed reports on the subsurface conditions surrounding your construction using our ground penetrating radar systems and our underground utility locator.
