A 3-D seismic data volume is like the room-temperature example except for two changes:

A 3-D seismic data volume is like the room-temperature example except for two changes:

* The vertical axis is [[two-way traveltime]], not depth.

* The vertical axis is [http://wiki.seg.org/wiki/Dictionary:Traveltime two-way traveltime], not depth.

* The data values are [[seismic amplitude]]s rather than temperature.
