It’s probably easiest to have the data always end up in the same directories and choose a new cruise name to use. Then after the cruise you can stop logging and use a file browser to move the data to a different directory.
So, choose a new cruise name. Something simple and descriptive like TN165 or KM0404 for the whole cruise.
“Ensemble Time” here refers specisically to the bottom of the “ADCP Setup” Tab, and it refers to the “seconds between ensemble” (where an ensemble is usually just one watertrack ping, or might be a pair of pings: one bottomtrack ping and one watertrack ping). This setting DOES NOT have anything to do with the averaging of the data later.
higher precision mode
If the cruise is in the open ocean and the science party is biologists or people interested in upper-ocean processes, use broadband pings with 8-meter resolution to get better vertical resolution and higher precision at the expense of depth penetration.
lower precision mode
If the cruise is in the open ocean and the scientists on board are interested in currents as deep as possible, use narrowband pings with 16-meter bins. Deepest profiles might be to 800m, but with lower vertical resolution.

double these durations for 38KHz
It is important to remember to change the “Ensemble Time” to match the ping pattern. The computer actually tells the instrument when to ping; the ADCP doesn’t figure that out for itself. If it’s too small, you may have interference. If it’s too large, you waste the opportunity to ping.
