CalCOFI 0911NH Editing notes
This cruise had persistent problems with the ISUS continuity which resulted in
many dropout on voltage channel 4. In order to derive the best station-corrected
estimated ISUS NO3, V4 in the asc files were edited. Bad voltages were "-99.000"
so they would be excluded from the dynamic regression routine that derives estimated
NO3 from the ISUS voltage vs bottle nitrate comparison.
The original asc files with .bak extension are included here for end users who may
prefer working with unchanged .asc files.
