Geological Engineering. BSc university. UT Austin. W. Harry Mayne (April 29, 1913-April 7, 1990) was an American geophysicist, who invented the Common Depth Point (CDP) stacking method of signal enhancement, and served as the 1968 SEG President. Harry was awarded SEG's highest honor, the Maurice Ewing Medal, in 1983. We exploit estimates of P‐wave reflectivity from autocorrelation of transmitted teleseismic P arrivals and their coda in a common reflection point (CRP) migration technique. The approach employs the same portion of the vertical‐component seismogram, as in standard Ps receiver function analysis. This CRP prestack depth migration …
