ONE-CHANNEL ATTENUATION MEASUREMENT
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.
						61105.001-123?)	dws61105.115	tar70208
						Runs 116-125?
11-12-96  The USGS is installing equipment 
   - 3 ADCP's, 2 S4 current meters.
						61112.001-119	dws61112.116	tar70208
						Runs 117-119 during tests
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.
						61119.001-119	dws61119.108	tar70208
						Runs 109-119?
11-26-96  At the Slough to observe the USGS
   retrieve their instruments.  The computer
   was hung up because the m-sequence
   generator had been un-plugged, and didn't
   restart properly.  I restarted the m-
   sequence generator, THEN stopped that
   data during run 119.

						61202.000-.162	dws61202.162	tar71124
12-11-96  Installed a cable from the pier
   to the near piling.  Data-taking
   continued uninterrupted.
12-12-96  Connected the cable installed the
   day before.

START OF 1997				cur files	dws file	tar file(s)
1-16-97  At Slough to collect data.  The
   near pier is GONE.  Disk full.  Bring
   apparatus back to SFSU.
