The CalCOFI IEH archive includes two versions: observed data only (YYMMarch.ieh) and observed data plus interpolated standard levels (YYMMt.ieh). Interpolated data are added to allow standard depth comparisons & plotting when observed standard depths are not available.

The IEH format was developed in 1982 as the final bottle data archive format for CalCOFI data. The IEH format is 128 columns wide, based on the 128-col computer punch card used at the time. Decimals are removed to maximize data space resulting in a column-specfic format - see key below. In IEH files generated before Aug 1995, columns 64-65 contain format alignment characters (Z*) throughout all records; after Aug 1995, columns 64-65 report niskin bottle numbers on the bottle depth records. Interpolated depth do not have a bottle number so columns 64-65 are blank.

In 2006, the Station Id Line & Sta are reported to tenths (i.e., 81.8 46.9 instead of 82 47 or 86.7 100.0 instead of 87 100). This change allows the inclusion & resolution of coastal SCCOOS station data from nearby standard station data. SCCOOS stations can be within the 2 nautical mile radius of the standard station ie 93.3 26.4 SCCOOS & 93.3 26.7 Standard stations.

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 Jennifer Rodgers-Wolgast at x42888.
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.
8/95 jrw. changed col 64-65 from *Z format verification to bottle number
