1. n. [Geophysics]

The seismic data recorded for one channel. A trace is a recording of the Earth's response to seismic energy passing from the source, through subsurface layers, and back to the receiver.

2. n. [Formation Evaluation]

The presentation on hard copy of log data from a single measurement versus depth. The term originated with the early optical recorders in which log data were recorded on film using an optical trace. Now the term curve is more common.
