Sensor log

The sensor log is a log recorded by various sensors on starships, space stations, probes and more. The log can be re-examined at a later time.

Starfleet Intelligence agents Bridget McLellan and Cervantes Quinn were sent on a mission to the Gorn Hegemony controlled planet of Tzoryp in 2268. There they were instructed to copy the sensor logs from the Orion freighter Treana onto a data card. Before they could complete the mission, the Treana was destroyed by Goloth, a Klingon Imperial Intelligence agent. 

In 2375 Tuvok was reviewing the sensor logs when the USS Voyager warp field to find out why the ship had been struck by mines. (SS VOY (The Secret Heart of Zolaluz))
