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 (i.e., 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.
