  COMMENTS                    : 
This cruise had two ADCPs: NB150 and OS38, the latter interleaved
with broad and narrow band.  However, the OS38 failed during the
cruise.  Only short segments from the broadband (SACID 01058) and
the narrowband (SACID 01522) are available.

The NB150 data are available for this cruise under SACID 01057.
