There were only 6 salinity calibration samples taken during this cruise, of which only 3 were below 5m. THe deep samples were lower than bottle salinity by 0.003psu or less, and low by up to 0.006psu allowing for incomplete flushing of NIskin bottles. The differences are much larger for the surface samples, but differences in timing of CTD and bottle sampling and high local salinity gradients make these comparisons unsuitable for calibration checks. Salinity is likely good to +/-0.005psu. Extracted chlorophyll samples were mainly gathered at the surface using a bucket, but 3 samples came from a Niskin bottle at 5m. CTD fluorescence data are spiky above 1m, so CTD data for comparison were drawn from about 1.5 to 2m. The ratio of CTD Fluorescence to Extracted CHL samples was somewhat lower than usual for surface samples, but for the samples from 5m the fluorescence was about 70% of the CHL samples. The ratio of fluorescence to CHL dropped with increasing CHL, as is usually seen from these sensors. The sensor appears to have performed well. Oxygen:Dissolved:SBE values cannot be confirmed as there was no calibration sampling for dissolved oxygen. Surface saturation values were between 60% and 180% with all values <100% coming from areas where vertical mixing may be strong.
