Malehmir, Reza; Schmitt, Douglas R (2017): Acoustic reflectivity from water-alpha Quartz boundary and double Schoch shift [dataset]. University of Alberta, PANGAEA, https://doi.org/10.1594/PANGAEA.873392

In this experiment, we measured acoustic reflected wavefield from water and z-cut alpha quartz interface in wide azimuthal and incidental directions. This unique dataset was collected at Experimental Geophysics Group at the University of Alberta, with the large transmitter and fine receiver with the resonant frequency of 0.7 MHz and the temporal sampling of 10ns, the incident angular sampling of 0.25 degrees and azimuthal sampling of 10 degrees. Measured acoustic reflectivity indicates double Schoch shift and null reflection at the Rayleigh angle of water-alpha quartz boundary. The double Schoch shift collapses into one where the azimuthal directions are parallel to the plane of anisotropic symmetry.

Zip archive contains 19 plain text files and 19 JPEG graphic files. 'AXX.txt' = Tab deliminated amplitude from Azimuth 'XX' degrees and each column is starting from '15.00' degees incidental angle and increments by 0.25 degrees (column-by-column) from left to right.
