The movement of data from the mainframe legacy STORET application to the new Legacy Data Center.\n\n4. The movement of chemicals, bacteria, gases, etc. in flowing water or vapor in the subsurface. Also, a seismic/radar term whose general meaning is the correction of the recorded image for the effects of reflector dip.
