This is the standard bundle for National Oceanographic Data Center
(NODC) accession data. Each accession maintained by NODC is given a
unique integer identifier known as an 'accession id'. All information
related to that accession is contained within a directory using the
accession id as the directory name. The accession directory has the
following standard structure:

<accession id>: This directory

  NODC-Readme.txt: This file.

  about: Directory. Contains all accession related metadata including but
         not limited to the following two standard files.

    journal.txt: Text file. Contains any notes, correspondence etc. relating
         to this accession.

    <accession id>.md5: Text file: contains MD5 checksums for all files in this
         accession except for the <accession id>.md5 file itself.
         other metadata: ...

  data: Directory. All accession data is located in the 'data' directory.

    0-data: Directory. Contains the originator's data unmodified from its
         intial digital format as submitted to NODC. The initial source for
         this data should be documented in the header of the:

         <accession id>/about/journal.txt

         file after the keyword, 'Source'.

    1-data: Optional directory. May contain processed version of originator's
         data from '0-data' directory. E.g. unzipped, uncompressed, untarred,
         or otherwise extracted or modified data. A note should be found
         in <accession id>/about/journal.txt explaining how files in
         1-data were derived from the files in 0-data.

    <n>-data: Optional directories. Additional processed forms of originators
         data. Similar to 1-data above.

- albatross.txt is a summary of e-mail messages with additional info on
  the submitted data.

- albatross_cruisereport.doc is a Microsoft Word document with the
  originator's cruise report.

- Files albatross.bot and albatross.ctd were created with the program
  reformat.f using the info in submitted files ALBATROSS-bot-nodc.asc
  and ALBATROSS-ctd-nodc.asc, and the headers in file stations_list.
  File stations_list is a text version of Table 1 in document
  albatross_cruisereport.doc.

  The header line in the files albatross.bot and albatross.ctd have
  the following information,

  Ship code: 74JC (James Clark Ross)
  Cruise ID: JR40
  Station number:
  Day
  Month
  Year
  Time: hours and minutes, UTC
  Latitude: degrees, minutes (2dp), and hemisphere
  Longitude: degrees, minutes (2dp), and hemisphere
  Corrected bottom depth: meters
  Number of water samples: only in albatross.bot file.  Number does not
  always match actual number of observations.

  The data lines in the albatross.bot file have the following information,

  Station number
  Latitude: degrees (2dp)
  Longitude: degrees (2dp)
  Pressure: db
  CTD temperature: degC, ITS-90
  CTD salinity: PSS78
  CTD dissolved oxygen: umol/kg
  Bottle salinity: PSS78
  Bottle dissolved oxygen: umol/kg
  Nitrate+Nitrite: umol/kg
  Phosphate: umol/kg
  Silicate: umol/kg

  The data lines in the albatross.ctd file have the following information,

  Station number
  Latitude: degrees (2dp)
  Longitude: degrees (2dp)
  Pressure: db
  CTD temperature: degC, ITS-90
  CTD salinity: PSS78
  CTD dissolved oxygen: umol/kg
