CalCOFI 9408NH CTD Date Processing Notes

Number of station-casts: 66 standard CalCOFI Station

Summary: The single set of primary sensors: temp, cond, & O2 worked well this 
cruise and no replacements were required. All sensors were on their first cruise since
being serviced & calibrated. The O2 sensor downcasts do not agree as well as the upcast
near-surface, typical of the YSI O2 sensor. 
Agreement with the bottle samples was very good so the r-squares were low on O2s. There
were no issues by the CTD operators this cruise. 

Software: DOS Datcnv(Seasoft exe), running in a Windows XP virtual machine on Windows 7.
Additional Seasoft processing done using v7.23.2 SBE Data Processing. Since the no sensors were
changed, only one .xmlcon file was used in the Derive module. 

Casts 005, 010, 018, 055, & 059 were ~800m casts.
Casts 014, 024, 032, 041, & 045 were ~1500m casts.

Corrections:
Cast 001-003: CTD oxygen sensor data were bad, the sensor did not appear to be changed. But
after 3 casts, it started working. These data are flagged bad '9' in the stations.csvs.
