This directory holds the following:

subdirectory codas/
There are subdirectories for each unique sonar-cruise set,
which is given an SACID number sssss, for sets that have
the high resolution shipboard ADCP data in the Common
Oceanographic Data Analysis System (CODAS) binary format.
0067774v3.3 includes all the original files from 0067774v2.2
plus three additional files: sssss_long.nc, sssss_short.nc,
and sssssv3.nc.  (Note, select 0067774v2.2 sonar-cruise sets
had working files that were inadvertently added.  For
0067774v3.3, these working files were removed).

subdirectory non_codas/
There are subdirectories for each unique sonar-cruise set,
which is given an SACID number sssss, for sets that do not
use CODAS format.  A NetCDF version of the ASCII text
Standard Subset file is added.  Otherwise, these files are
unchanged in 0067774v3.3 relative to 0067774v2.2. (Note,
select 0067774v2.2 sonar-cruise sets had working files that
were inadvertently added.  For 0067774v3.3, these working
files were removed).
