CalCOFI 0007NH CTD Data Processing Notes

CalCOFI 0007NH CTD data look pretty clean overall. The secondary conductivity
sensor which is occasionally spikey looks pretty good this cruise. There are some
mild spikes in the upper 70m on some casts but nothing worth flagging as bad.
The Beckman/YSI oxygen sensor had some issues near surface on the downcast
underestimating the oxygen measurement even after the bottle correction has been
applied. So be aware the CTD O2 values near surface on some casts may be less
than bottle sample values.

There were very few errors in file labeling or cast problems. Casts 001 & 002
ship was label "David Starr Jordan" in the .hdr files. These were corrected.
Station 50 83.40.6 station value was corrected to 83.3 40.6.
Lastly, the transmissometer & fluorometer configuration was reversed. Fluorometer
was on V0 & transmissometer was on V1. The con files have them reversed.

One of the "cleanest" & easiest cruises to reprocess. JRW 2021
