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

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.
