Electrical Conductivity Structure in the South-east Australian Region
نویسنده
چکیده
An array of variometers across south-east Australia has recorded natural magnetic variations having power in a frequency band of 0.04-10 cycles/hr. The set data have outlined two major regions of high terrestrial electrical conductivity (c); the first beneath the sea floor off the Australian southeast coast; the second in the vicinity of the most recent eruptive centres of the ‘ Newer Volcanics ’ in western Victoria. Both regions may indicate low Q upper mantle zones. Daily variation data provide significant control on permissible conductivity models.

The total-field geomagnetic coast effect: The CICADA97 line from deep Tasman Sea to inland New South Wales
In the CICADA97 experiment a line of simultaneouslyrecording stationary vector magnetometers was deployed from inland NSW, across the east Australian coast, and into the Tasman Sea. The purpose of the experiment was to investigate the effect of electrical conductivity structure near a coastline on natural timevariations in Earth’s magnetic field. Aeromagnetic surveys regularly take place in suc...

The variations of the electrical conductivity with temperature and electric field of the ternary alloy of gallium, aluminium and arsenic (Al0.75Ga0.25As) with atomic compositions of 99/1 and 98/2 have been investigated. The electrical conductivity of the alloy increases with temperature according to the relation, ? = ?0 exp (??/kT). The activation energy calculated from this empirical relation ...
