Samples were extracted in 90% acetone at -20C for 24 hours in the lab and analyzed on a Turner 10AU fluorometer calibrated with commercially pure chlorophyll a standard (Sigma). Fluorescence readings taken before and after acidification were used to calculate chlorophyll and phaeopigment concentrations (Holm-Hansen et al 1965). Chlorophyll samples were analyzed at IOS in Room 2423 1 to 5 weeks after the cruise. Variability is assessed as the CV% (std dev / mean*100). Flags and comments apply to chlorophyll values only. Chlorophyll values ranged from 0.05-20.68 ug/l in 103 samples. Average %CV for this cruise was 5.86% (after one duplicate was rejected, original 8.25%) with 5 out of 23 duplicate pairs having a CV>10% and 0 duplicate pairs having a CV>30%. Our average dataset %CV is 3.83% for 2013 - 2020 so the overall quality of this dataset is acceptable. For details see worksheet “CV%” in file QF2021-008_CHL*.xlsx. Oxygen samples were analyzed at sea using an automated Winkler titration System (Metrohm Dosimat model 876 and a UV light source and detector with a 365nm filter controlled by LV02_876 software designed and constructed by Scripps Institution of Oceanography) with modifications based on Carpenter (1965) and adhering to WOCE protocols (Culberson 1991). For details including a duplicate analysis, see document QF2021-008OXY*.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 68 - 75 days after collection. For details including a duplicate analysis, see document QF2021-008SAL*.xlsx. Nutrient samples were collected in plastic tubes and quick frozen in aluminum blocks stored in a -20C freezer. For samples 400m and deeper a second set of samples are collected and stored cool for silicate analysis. All samples were returned to the Insitute of Ocean Sciences and they were analyzed using an Astoria-Pacific Analyzer following methods described in IOS Nutrient Methods (1996) Barwell-Clarke and Whitney. For details including a duplicate analysis, see document QF2021-008nuts*.xlsx. DMS samples were collected in 250mL ground glass stoppered bottles and stored in a fridge, in the dark and removed one at a time before analysis. A sample was loaded onto the stripper and purged with UHP Nitrogen for 10 minutes at ~100mL/min. The DMS was extracted from the water and absorbed into a Tenax TA trap kept at -80C. The trap was subsequently desorbed at 100 deg C (with a dewar containing boiling water) onto a Chromosil 330 column which eluted onto a Flame Photometric Detector (FPD). All samples were run as soon as possible after being collected. The minimum detectable level for DMS is 0.10 nmol/L, so “0” values should be interpreted as <0.1nmol/L. DMS data are limited to 2 significant figures. Unless otherwise indicated the % relative difference between duplicates is <20%. For more detail see file "2021-008 DMS report*.doc" and for data and duplicate analysis see "QF2021-008_DMS_summary*.xls." DMSP-D: Approximately 50-100mL of seawater is drained from the niskin into a magnetic filtration funnel containing a 0.7um GF/F filter. The first 3.5mL is collected in a polypropylene tube containing 50uL of a 50% sulphuric acid solution. A new funnel and filter are used for each sample. DMSP-T: 3.5mL of seawater was collected directly from the Niskin into a polypropylene tube (15mL) containing 50uL of a 50% sulphuric acid solution. DMSP-D and DMSP-T: Samples are stored in the dark at 4 degrees C for a minimum of 24 hours. They are hydrolized and analyzed at the Institute of Ocean Sciences when time permits. The minimum detectable level is 0.1 nM, so “0” values should be interpreted as <0.1 nM. DMSP data are limited to 2 significant figures. Unless otherwise indicated the % relative difference between duplicates is <20%. For details on analysis and raw data, see document "QF2021-008_dmsp_summary*.xlsx. References: 1.

There were 2 WetLabs CStar transmissometers in use during this cruise: Channel Transmissometer refers to sensor #1185DR (650nm - red) Channel Transmissometer:Green refers to sensor #1883DG (530nm - green) For comparison with other Institute of Ocean Sciences cruises, note that the transmissometer wavelength is 650nm unless otherwise stated. NOTE: While the CTD fluorescence data are expressed in concentration units, they do not always compare well to extracted chlorophyll samples, particularly for casts far from shore. It is recommended that users check extracted chlorophyll values where available. Both salinity channels were found to be reading much lower relative to bottle samples than in 3 previous cruises using the same equipment, and a little lower than during the cruise that followed. Channel Salinity:T1:C1 was found to be lower than bottles by an average of 0.0055psu in deep water. Since delayed analysis and small errors due to incomplete flushing both would have led to bottle values being too high, no recalibration was applied to the CTD salinity. While confidence in the bottle comparison is lower than usual, it is likely that channel Salinity:T1:C1 is within ±0.003psu. The dissolved oxygen sensor was mounted on the primary pump and all primary channels produced bad data for cast #37. The system returned to reasonable values by the end of the cast, but there was some evidence of drift in primary temperature and salinity thereafter. The dissolved oxgyen data looked ok in the comparison with bottles except for cast #37. Dissolved oxygen was removed from file 2021-008-0037.che. For details on the processing see the report: 2021-008_Processing_Report.doc. --------------------------------------------------------------------------------- *CALIBRATION $TABLE: CORRECTED CHANNELS !
