The
CalCOFI IEH archive
includes two versions: observed data (YYMMarch.ieh) and interpolated standard levels (YYMMt.ieh).
The IEH format was developed as an archive format for the CalCOFI data. Prior to
Aug 1995, columns 64-65 contained format alignment characters (Z*).
Starting in 2006, the Station Id will report Line & Sta to tenths ie 81.8 46.9 instead of 82 47 or 86.7 100.0 instead of 87 100. This change was made to
allow the inclusion of coastal SCCOOS station data with nearby standard station data.
(IEH stands for "Is Everybody Happy?" coined by programmer David Newton.)

-----------------------------------------------------------------------------
** Codes and usage **
1. Quality code. Used on the detail records.
blank == data ok
'6' == data ok,but taken from a ctd device.
(used only when data is, on the whole, considered
to be bottle data)
'8' == originator thinks value is suspect.
'9' == missing data
2. Examples of Calcofi station numbers. b=blank
b93bbb40bb 110bbb40bb
110bbb40.2 b93.1b40bb
b93.2b40.1 110.1100.3
3. Missing or unrecorded data MUST be indicated with a '9' in the quality
code.
4. Trailing blanks are only allowed when specifically mentioned and
when they are mentioned, their use is required if the precision
is less than the maximum.
5. The ship ownership country and institution can be different from
the data ownership country and institution.
6. The format can be folded into a 64 character variety if that makes
data entry more convenient, but the specification and any application
programs will operate on the 128 character variety listed here.
7. Any interpretation problems should be referred to David Newton at
x46273.
8. The first master record should be immediately followed by the second
master record.
9. Times in HHMM format should be written with no embedded blanks.
10. Ghostcards (rectyp=4) are used for interpolation but not printed to
data reports. Multiple depth cards (rectyp=6) are *not* used for
interpolation but *are* printed to data report.
Revisions:
5/12/87 dmn. Probably added some notes.
5/ 9/91 dmn. Added word incubation to light percent explanation.
8/21/95 dmn. added bottle id number to data records.
added rcord type 6 (multiple depth card).
added usage note 10.
