Deployment 2013 to 2014:
calibration info for SBE37 #5084




The calibration adjustments were based on the drift determined from the laboratory
calibrations at SeaBird before and after the deployment. The SeaBird sheets, while
very helpful, can be confusing at first sight (they have confused me in the past).
Mostly as guide to myself, I went into some detail when outlining the process for
the 2014-16 microcats.


Conductivity:
As is often the case, the SeaBird lab calibration indicated that the cell had
"drifted low". The drift did not appear to be alarmingly large, but was still deemed
suffent to warrant a re-platinization - which resets the cal values. The adjustment
for the just recovered data was therefore based on the calibration done prior to
the reset, aptly stamped "postcruise cal":



The magnitude of the salinity change based on the conductivity adjustment ranged from
0 at deployment time to 0.013 psu at recovery time.




Temperature:
The lab calibration indicated that no temperature adjustment was needed.



Pressure:
The pressure sensor tends to be quite stable. This was confirmed by the SeaBird post-deployment calibration.
