Document Summary

Cedar-wood ships were found at giza using subsurface detection. Ground-based remote sensing and geophysical surveys are non-invasive; they can detect what is below the ground without disturbing the ground. The instruments measure fluctuations in electrical or magnetic fields in the earth. Geophysical surveys detect anomalies in the soil that may be of archaeological significance. The simplest instrument of geophysical survey is the metal detector. Others are the magnetometer, electrical resistivity, electrical conductivity, and ground-penetrating radar (gpr). All these methods can be used before or during excavation. Such geophysical surveying is being done at wroxeter, england, which was the fourth- largest urban centre in roman britannia. At wroxeter, archaeologists have obtained the most comprehensive map of a roman site in britain, without actual excavation. There are ruins above ground at wroxeter, such as the hadriatic baths. See pages 102 103 for more info on wroxeter. The search for subsurface features can also include probing and drilling.
