Research Projects - Radar and Shallow Geophysical Studies

Ground-penetrating Radar (GPR) is recognized as one of the fundamental tools for probing subsurface geology. We have used GPR soundings and surface and subsurface backscatter characteristics of the P- and L-band polarimetric airborne synthetic aperture radar (AIRSAR) data to resolve different exposed and buried lava flows in Mars analog environment at Craters of the Moon (COM) in Idaho.
Currently we are using GPR to determine the 3-D facies geometry and facies heterogeneity of Albian rudist communities of the Edwards Formation, Fredericksburg Group, in Central and South-Central Texas. This work holds potential for hydrocarbon exploration in shallow realms and for hydrological applications in carbonate terrains.
We are using radar altimetry and optical remote sensing techniques to estimate and find causes of water level fluctuations in Caspian Sea.
