A comparison of the stability of stationary and non-stationary magnetotelluric analysis methods

Autor: L. M. Hastie, I. J. Chant

Publikováno v: Geophysical Journal International. 115:1143-1147

A Magnetotelluric (MT) sounding was carried out at a site in south‐east Queensland, in the Clarence‐Moreton Basin. The synoptic recordings were taken over a period of four months at sampling frequencies from 500 Hz to 5 × 10‐5 Hz. The resultin

Time-frequency analysis of magnetotelluric data

Autor: L. M. Hastie, I. J. Chant

Publikováno v: Geophysical Journal International. 111:399-413

The natural signal magnetotelluric (MT) and audiomagnetotelluric (AMT) geophysical prospecting methods utilize the spectra of associated time‐varying horizontal electric and magnetic fields at the Earth's surface to determine a frequency‐dependen

A Comparison of Magnetotelluric Analysis Methods Based on Data from a Site in the Moreton Basin

Autor: Lynn M. Hastie, I. J. Chant

Publikováno v: Exploration Geophysics. 19:417-422

A magnetotelluric (MT) system with sampling frequencies in decade steps from 1 kHz to .01 Hz was operated at a site in the Moreton Basin, near Peaks Crossing, Queensland. The data were analysed by both the conventional rotated impedance and the Spitz

Ionospheric induced very low‐frequency electric field wavetilt changes

Autor: David V. Thiel, I. J. Chant

Publikováno v: GEOPHYSICS. 47:60-62

Very low‐frequency (VLF) electric field wavetilt measurements were made continuously over a period of four months at a fixed location. Daytime and nighttime values of the wavetilt were found to be relatively constant. During sunrise and sunset the

Reply by the authors (D. V. Thiel and I. J. Chant) to J. R. Wait

Autor: I. J. Chant, D. V. Thiel

Publikováno v: GEOPHYSICS. 49:1389-1389

In his discussion of our paper Wait refers to the effect of an elliptically polarized radiation source on both electric field wavetilt and surface impedance measurements. If such measurements are made at the surface of a uniform isotropic half‐spac

On: 'Ionospheric induced very low frequency electric field wavetilt changes' by D. V. Thiel and I. J. Chant (GEOPHYSICS, Jan., 1982, p. 60–62)

Autor: D. Rankin, Ramesh P. Singh, James R. Wait, I. J. Chant, David V. Thiel

Publikováno v: GEOPHYSICS. 49:1388-1388

With all due respect to Singh and Rankin (1983), I believe that their criticism of the paper by Thiel and Chant (cited above) needs clarification. Contrary to the assertion by Singh and Rankin, the quoted formula for the function [Formula: see text]
