Geomagnetic depth sounding by means of oceanographic and aeromagnetic surveys

Proceedings of the IEEE, 1979
The investigation of underground conductivity structures by means of geomagnetic data (i.e., geomagnetic depth sounding (GDS)) has been extensively carried out over land areas using three component recordings. However, the large amount of data collected for many years by airborne and/or shipborne magnetometry all over the world have generally been used

Geomagnetic depth sounding by induction arrow representation: A review

Reviews of Geophysics, 1980
Considerable important research in upper atmosphere geophysics is carried out through the use of arrays of ground‐based magnetometers. In order to better delineate the ionospheric and magnetospheric currents and waves as measured by these arrays, it is important to understand the conductivity of the earth's structure under the individual stations ...

C-responses estimation of geomagnetic depth sounding using regularization method and its application in Northeast China

Journal of Applied Geophysics, 2021
Abstract In this paper, we introduce a technique to obtain smoother C-responses in geomagnetic depth sounding. Instead of frequency by frequency, C-responses in entire frequency range are estimated simultaneously. In order to do so, after obtaining the spectrum of Hy and Hz, the equations relating C-response with Hy and Hz are combined for a batch ...

Quantitative interpretation of geomagnetic depth-sounding data in western Canada

Journal of Geophysical Research, 1971
Geomagnetic depth-sounding (GDS) data obtained at two stations in western Canada have been interpreted in terms of electrical conductivity structure. The two stations (Penticton and Pincher) are located about 150–200 km to either side of the main discontinuity between an area of low vertical component variations (low Z) and an area of high vertical ...

Geomagnetic depth sounding and upper mantle structure in the Cordillera region of western North America

Journal of Geophysical Research, 1967
This report describes recent geomagnetic depth-sounding investigations on the inland (Cordillera) anomaly first reported by Schmucker at latitude 32°N. It includes Hyndman's profile at latitude 49.5°N and two subsequent profiles at latitudes 35°N and 51°N. All three profiles crossed the transition between the ‘high-I’ and ‘low-I’ zones.
