11-3-96  Set up to measure attenuation.
   Ch A = transducer drive, Ch B =
   received signal, N to S.
						61103.004-036	dws61103.035	tar70208
11-5-96  Check data on way to Sacramento.

						Runs 116-125?
11-12-96  The USGS is installing equipment 
   - 3 ADCP's, 2 S4 current meters.
						61112.001-119	dws61112.116	tar70208

11-19-96  At the Slough to pick up data.
   The ADCP is apparently still installed,
   from the end of the pier.
11-19-96  Back at the lab:  I verified that 
   the time we record is correct.

11-26-96  At the Slough to observe the USGS
   retrieve their instruments.  The computer

   generator had been un-plugged, and didn't
   restart properly.  I restarted the m-
   sequence generator, THEN stopped that
   data during run 119.

6-20-97  Collect data; take computer to
   SFSU for repairs
						70622.007-034	tests		tar70813.dir
6-24-97  Computer repaired; data bad?
   500-event runs!  R058-977 deleted.		70624.023-977			tar70813.dir
6-27-97  Turn system off.
7-5-97  FOUND ERROR IN PINK (data acqui-
   sition program); currrent values have
   been wrong since waveform averaging
   was introduced (Aug 1996?)
7-9-97  Start taking data.
						70709.016-231	dws70709.231	tar70813.dir
