Comparing performance of instrumental drift correction by linear and quadratic adjusting in inductive electromagnetic data

► We comparing the performance of instrumental drift correction by linear and quadratic adjusting in Inductive Electromagnetic data. ► The correction of drift by quadratic relation was effective for location of metallic pipes, and electrical cables. ► This research was done under field controlled conditions at IAG-USP test site (São Paulo, Brazil). ► Electric conductivity and magnetic susceptibility anomalies were enhanced, and deeper targets were improved. ► The data acquisition is faster because it is not necessary to survey at base line and its re-occupation.
