Gladiola v.1

Gladiola  is a free  win32 application for MT static shift correction. The program reads MT EDI files and uses the given shallow structures (from TDEM)  to produce the theoretical undisturbed MT tensor. The following figure shows the screenshot of the Gladiola. The plots are based on a synthetic dataset. The left panel is rhoapp vs T, while the right panel is phase vs T. Blue dots on the left panel stand for rhoxy,  and the red pluses stand for rhoyx, while the black dots with line represent the TDEM derived MT curve. The solid blue line is the corrected rhoxy, while the solid red line is the corrected rhoyx. The points that have very low values are the rhoxx and rhoyy.

Static shift on MT

The irregularity of topography causes static shift on MT records. One remedy to the disturbance is to run TDEM (time domain electromagnetic) survey.
