For details including a precision analysis, see document QF2022-067OXY*.xlsx. Salinity samples were collected in 200 mL type ll glass bottles with disposable nylon inserts and screw caps supplied by Ocean Scientific International Limited. They were analyzed in a temperature-controlled lab on a Guildline 8400B Salinometer standardized with IAPSO standard seawater 21 - 42 days after collection. For details including a duplicate analysis, see document QF2022-067SAL*.xlsx. References: 1. Barwell-Clarke, J. and Whitney, F. 1996. Institute of Ocean Sciences Nutrient Methods and Analysis.

Waits before firing Niskin bottles were generally 60s. The SBE DO sensor calibration changed during a previous use in 2022. No change was noted during this cruise, though the correction (based on comparison with titrated samples) is larger than normally seen for this type of sensor. Channel Salinity:T1:C1 was found to be lower than bottles by about 0.002psu, but bottle values are likely a little high due to incomplete flushing of Niskin bottles and evaporation or desorption of glass particles into samples. CTD salinity is likely within +/- 0.002psu. No recalibration was applied to salinity. For details on the processing see the report: 2022-067_Processing_Report.doc. --------------------------------------------------------------------------------- Channel Fluorescence was removed because the values found were extremely low and compared very badly with extracted chlorophyll samples.
