There were only 6 salinity calibration samples taken during this cruise, of which only 3 were below 5m. The CTD data were lower than the deep bottle samples by an average of 0.001psu; the CTD may be reading low by a little more than that due to incomplete flushing of NIskin bottles. Salinity is likely good to +/-0.005psu. 10 extracted chlorophyll samples were collected at the surface using a bucket, while the CTD was soaking at 10m during a regular CTD cast. 3 samples from 5m came from a Niskin bottle during chito casts. The ratio of CTD Fluorescence to Extracted CHL samples was somewhat lower than usually seen especially at the low end of the range, but it is consistent with other uses of this equipment during 4 other 2024 cruises in the same area. Oxygen:Dissolved:SBE values cannot be confirmed as there was no calibration sampling for dissolved oxygen. Surface saturation values were all between 100% and 135% except for station 56 where it was 65%. That is a site of active mixing. It is likely that SBE dissolved oxygen values are slightly low with typical errors for these sensors being from 1% to 3%.
