September 14, 2011 / Evan Bianco. When a geophysicist speaks about pre-stack data, they are usually talking about a particular class of gather. A gather is a collection of seismic traces which share some common geometric attribute. The term gather usually refers to a common depth point (CDP) or common mid-point (CMP) gather. 1. n. [Geophysics] In multichannel seismic acquisition, the point on the surface halfway between the source and receiver that is shared by numerous source-receiver pairs. Such redundancy among source-receiver pairs enhances the quality of seismic data when the data are stacked. The common midpoint is vertically above the common depth point, or ... 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 … The common depth point (CDP) is the halfway point of the path only where the Earth is horizontally layered; it is situated vertically below the common midpoint (CMP). A gather is a family of traces (e.g. shot-point gather is the family of all traces corresponding to the same source firing).
