CEAREX Hydrography CTD Errors
Errors associated with CTD data have been identified on the CEAREX CD-ROM. Duplications of depth readings and missing header line spaces caused the errors in the hydrography data files, which are in the /HYDROG subdirectory of the CD-ROM.
The following files contain profiles with first header lines that are missing a space. This results in an error when trying to read in date and position of profiles.
File Name Profiles with Missing Space
BOTTLE/BOTTLE.DAT 527
SHIP/HUDSON.CTD 129
SHIP/KNORR.CTD 13
SHIP/METEOR.CTD 106
SHIP/STERN.CTD 32
SHIP/YMER.CTD 20
The following profiles contain duplications of depth readings or (in one case) depth inversions. Because the list contains the actual depths and profile numbers of the errors, it can be used to pinpoint the errors.
