CalCOFI 0411RR CTD Data Processing Notes:
Not a lot of scrutiny of data during reprocessing this first go round.
I hope to do more as time permits but now I'm just trying to get finished.
Overall the data look clean but the CTD oxygen sensor looks like it is underestimates
the surface oxygens. This was a problem until CalCOFI started drawing surface O2s 
first (instead of deep O2s first). Also, Seabird recommended warming up the 
electronics, including the O2 sensor, for 10 or more minutes on deck before 
deployment. This practice was adopted in 2005.
There were a few ISUS dropouts - voltage went to zero on a few casts but these
were not datacoded at this time May 16 2019.

Casts with no ISUS data: Cast 003, 022, 061, 067 (not bad)

Casts with mislabeled hdr info:
Cast 030: Station mislabeled 90.27.7, fixed 90.0 27.7 (not hexedited)
Cast 052: Station mislabeled 83.40.6, fixed 83.3 40.6 (not hexedited)
Cast 053: Station mislabeled 83.39.4, fixed 83.3 39.4 (not hexedited)
