This was a verified copy of an old magneto-optical jukebox platter.


NODC created a new version of this accession (indicated as 1-version/, 2-
version, etc. as necessary) to add a re-formatted version of the data
initially available in the data/0-data/ directory (i.e., "original
version" of these data). 

An NODC metadata improvement project identified IGOSS data accessions
whose data in data/0-data/ failed to conform to the standard TESAC
format. The problem was identified: extraneous characters and/or a block
of 6 characters interpolated between character 80 and 81. Two programs
were created to restructure the content of the data files (data values
were not changed). The restructured data files were copied to
data/1-data/ and use the existing data file number (minus the .) with
.fixed and .field extensions. 

The data/1-data/*.fixed files are consistent with the TESAC format and
have the extraneous characters and interpolated blocks removed. 

The data/1-data/*.field files were created as an interpretation of the
.fixed files as a check that these data conform to the TESAC format.
These data were rearranged into a temperature and salinity profile
format. The cruise and station information are in a field-oriented
format. Fields that have missing data are left blank or are indicated by
a "NOT AVAILABLE" next to the field. The field format appears to make
sense, with only one small exception. The format description says that
the 'Air Temperature Indicator' should be blank for "no data", and 2 for
"data present". But the data value in some files have that field as
either blank, or "4". So the interpreted value is marked with "??" in
the output listing. The values do indeed look like sensible air
temperatures.

No data values were change by either of these processing steps.
