The temperature survey showed...
Water levels and salinities of water within the Evangeline Aquifer in an area southwest of Corpus Christi, Texas
Paul Rettman
1983, Open-File Report 82-174
During 1982, about 275 wells located in a 4,680 square-mile area southwest of Corpus Christi, Texas were measured to determine water-levels and specific conductance of water in the Evangeline aquifer. A large cone of depression with a maximum depth of 200 feet below NGVD of 1929 was identified near Kingsville....

A practical, low-noise coil system for magnetotellurics
William D. Stanley, Richard D. Tinkler
1983, Open-File Report 83-85
Magnetotellurics is a geophysical technique which was developed by Cagnaird (1953) and Tikhonov (1950) and later refined by other scientists worldwide. The technique is a method of electromagnetic sounding of the Earth and is based upon the skin depth effect in conductive media. The electric and magnetic fields arising from...
