Common depth point.

The two-dimensional (2-D) geophysical data in the BOEM inventory is common depth point (CDP) seismic information collected along a survey line. Also known as common midpoint or common reflection point data, the data are derived from a common location in the ocean This is called the Common Depth Point (CDP) method because the data is repeatedly recorded over increasing source to receiver offsets, but with the raypaths reflecting off the same depth location on each geological surface.
