There were only 6 salinity calibration samples taken during this cruise, of which only 3 were below 5m, of which 1 was collected an hour later than the CTD cast with which it was compared. The CTD data were lower than the 2 useful bottle samples by about 0.001psu; the CTD may be reading low by a little more than that suggests due to incomplete flushing of NIskin bottles. Salinity is likely good to +/-0.005psu. 8 extracted chlorophyll samples were gathered at the surface using a bucket, and 3 samples came from a Niskin bottle at 5m. CTD data for comparison were drawn from between 1.1db and 2.1db. The ratio of CTD Fluorescence to Extracted CHL samples was somewhat lower than usually seen, but this may be due to the sampling being so shallow. The ratio dropped with increasing CHL, as is usually seen from these sensors. Oxygen:Dissolved:SBE values cannot be confirmed as there was no calibration sampling for dissolved oxygen. Surface saturation values were between 70% and 110% with all values below 80% coming from near the Gulf Islands where strong vertical mixing is likely to be strong. Dissolved oxygen data from these sensors tend to be low by between 1% and 3%.
