Any non-spherical distribution of density inside planets and stars gives rise to a non-spherical external gravity and change of shape. If part or all of the observed zonal flows at the cloud deck of Jupiter and Saturn represent deep interior dynamics, then the density perturbations associated with the deep zonal flows could generate gravitational signals detectable by the Juno mission and the C...

Geophysical site characterization investigations at fuel spill sites have been generally guided by a working hypothesis Ž . which assumes that the light non-aqueous phase liquids LNAPL are a fully saturating phase of intrinsically very high electrical resistivity. Using observations from other related sciences, and contrary geophysical observations, a different model is developed which treats t...

Abstract In this paper, a new way of characterizing the mining-driven complex geological deformations is presented by utilizing continuous real-time microseismic (MS) data acquired through passive seismological monitoring. The was processed, and source parameters were computed encompassing over 60,000 MS events. correlation between events regional stratigraphy reveals that Upper Middle Xishanya...

Understanding the deformation mechanisms of olivine is important for addressing the dynamic processes in Earth's upper mantle. It has been thought that dislocation creep is the dominant mechanism because of extrapolated laboratory data on the plasticity of olivine at pressures below 0.5 GPa. However, we found that dislocation-accommodated grain boundary sliding (DisGBS), rather than dislocation...

Wadi aquifers in Saudi Arabia historically have been recharged primarily by channel loss (infiltration) during floods. Historically, seasonal groundwater levels fluctuated from land surface to about 3 m below the surface. Agricultural irrigation pumping has lowered the water table up to 35 m below the surface. The geology surrounding the fluvial system at Wadi Qidayd consists of pelitic Precamb...

SQUID systems, using either high temperature or low temperature superconductors, were developed for sensitive measurements in magnetically disturbed environments. They include the SQUIDs and fast SQUID electronics. Magnetometer SQUID systems are used for geophysical sounding, where they show superiority when compared to conventional induction coils for very deep sounding or fast measurement. Hi...
