"Gaseous anomalies"? I immediately think ST6 when I hear that bit of techno-babble. The movie begins with Starfleet's latest and finest "boldly going" out to do grunt work—mapping gaseous anomalies.
These GAs must be of great interest to the Federation—either that or there was a continuity error in the script—because towards the end of the movie Uhura asks, "Well, what about all that equipment we're
carrying to catalogue gaseous anomalies? ...Well, the thing's got to have a tail pipe."
They probably stumbled upon FARSCAPE's Rygel farting helium.
