Electromagnetic Resistivity (Other Keyword)

DOCUMENT Full-Text R. Berle Clay. Cultural Resource Analysts, Inc..

This report/manual focuses on the techniques and uses of the Conductivity survey, also known as the electromagnetic survey (EM) and how it measures the ability of the soil to conduct an electric current. The value, measured in siemens, is the reciprocal of resistivity (to convert to resistivity in ohm meters, divide the conductivity, in millisiemens per meter, into one thousand (Bevan 1983:51)). This said, there is considerable difference in the way earth conductivity and earth resistivity are...
