After thirteen days of surveying, the sonar towfish is recovered, and the Farnella steams for San Francisco bay to prepare for the sampling cruise.

Chief scientists Bill Schwab and Herman Karl use the sonar images as base maps to pick sites for sediment cores and underwater camera runs.
What about large targets?
Well, I'm not real concerned with large targets. I think the small targets - the drum issue is the real concern and then just doing some runs which we'll get, incidentally, while we are looking for the drums, to characterize the sea floor.
I know the chances of this are slight, but considering we don't know the location of the scuttled munitions ship, you may want to actually stay away from large targets.
That's right plus we don't want to {{{voices fade}}}
The two weeks of sampling will clarify and build on the scientists' interpretation of the sonar images. They will collect topographic profiles of the bottom, a sweep of sediment cores, and video and still photographs of the sea floor.
