There was unusual small-scale noise in the salinity channel, particularly in the primary channel. This mostly disappears with metre-averaging, but the quality of salinity is considered lower than usual. Despite the jitter the primary data looked better overall than the secondary, so were selected for archiving. The descent rate of the CTD was often extremely high, up to 2m/s. This led to some very large decelerations and data corruption due to shed wakes. NOTE: While the SBE fluorescence data are expressed in concentration units, they do not always compare well to extracted chlorophyll samples, particularly for casts far from shore. Salinity sampling was limited in quantity and quality and there was no dissolved oxygen sampling. Recalibration was applied based on previous cruises and one that followed and used the same sensors, as well as post-cruise factory calibrations. No estimate is possible for accuracy of downcast dissolved oxygen. The SBE DO sensor has a fairly long response time so data accuracy is not as high when it is in motion as it is during stops for bottles. This will be especially true when vertical DO gradients are large. With no dissolved oxygen sampling no estimate could be made of errors in SBE DO. The PAR sensor was removed after event #17.
