They were analyzed in a temperature-controlled lab on a Guildline 8400B Salinometer standardized with IAPSO standard seawater 21 - 49 days after collection. For details on duplicate analysis see document 2022-001_SAL.pdf. 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 on duplicate analysis see document 2022-001_OXY.pdf. Nutrient samples were collected in plastic tubes and quick frozen in aluminum blocks stored in a -20C freezer. For samples 400 dbar and deeper a second set of samples were collected and stored cool for silicate analysis. All samples were returned to the Institute of Ocean Sciences and they were analyzed using an Astoria-Pacific Analyzer following methods described in IOS Nutrient Methods (1996) Barwell-Clarke and Whitney. Salinity corrections were applied to Silicate data where Salinity:CTD values < 25 psu. SILcorrected = SILuncorrected [1+((-0.003)*(32-Sal:CTD))] For precision and duplicate analysis see document 2022-001_NUT.pdf. Chlorophyll samples were filtered onto 25mm GF/F filters and stored in glass scintillation vials at -80C prior to analysis. Samples were extracted in 90% acetone at -20C for 24 hours and analyzed on a Turner Trilogy 7200-000 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 12 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 0.03-8.21 µg/l in 82 samples. Average CV for this cruise was 2.49% from 23 duplicates, with 1 duplicate pair having a CV > 10% and 0 duplicate pairs having a CV > 30%. Our average dataset CV is 3.89% for 2013 - 2021 so the overall quality of this dataset is good. For details on duplicates see file 2022-001_CHL.pdf. References: 1.

There were 2 WetLabs CStar transmissometers in use during this cruise: Transmissometer:CTD:650 refers to sensor #1185DR (650nm - red) Transmissometer:CTD:530 refers to sensor #1883DG (530nm - green) For comparison with other Institute of Ocean Sciences cruises, note that the transmissometer wavelength is 650 nm unless otherwise stated. NOTE: While the Fluorescence:CTD 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. There were problems with spiking in the Fluorescence:CTD and Oxygen:Dissolved:CTD data during downcasts, but not during the window around bottle firing. For details on the processing see the report: 2022-001-proc.pdf. $REMARKS Quality flags have the following significance: ---------------------------------------------------------------------------------- 0 = Acceptable measurement with no header comment. 1 = Sample for this measurement was collected but not analyzed. Sample lost. 2 = Acceptable measurement with header comment. 3 = Questionable measurement (probably good). 4 = Poor measurement (probably bad). 5 = Measurement not reported (bad). 6 = Mean of replicate measurements. 7 = Manual chromatographic peak measurement. 8 = Irregular digital chromatographic peak integration. 9 = Sample was planned for this measurement from this bottle but was not collected. ----------------------------------------------------------------------------------- $END !-1-- 2- 3- --4--- ---5---- ---6---- ---7---- --8-- --9-- --10-- --11- ---12-- ---13--- 14 --15-- 16 ---17-- 18 --19-- 20 --21-- 22 --23-- !Samp Bo Bo Pressu Temperat Salinity Sigma-t: Trans Trans Oxygen Oxyge Fluores Salinity Fl Nitrat Fl Phospha Fl Silica Fl Chloro Fl Phaeo- !le_ tt tt re:CTD ure:CTD :CTD CTD missi missi :Disso n:Dis cence: :Bottle ag e_plus ag te: ag te: ag phyll: ag Pigmen !Numb ~u ~u vity: vity: lved: solve CTD: ~o _Nitri ~o Bottle ~o Bottle ~o Extrac ~o t:Extr !er mb en CTD: CTD: CTD: d:CTD Seapoin tt te: tt tt tt ted: tt acted: ! er ce 650 530 Volume :Mass t le Bottle le le le Bottle le Bottle !---- -- -- ------ -------- -------- -------- ----- ----- ------ ----- ------- -------- -- ------ -- ------- -- ------ -- ------ -- ------ *END OF HEADER 209 24 24 5.5 7.3586 32.3277 25.2917 56.6 89.3 6.93 301.8 0.741 32.3305 0 10.00 0 1.044 0 7.07 0 0.41 0 0.14 208 23 23 11.6 7.3624 32.3273 25.2909 56.7 89.4 6.93 301.6 0.729 -99.0000 0 -99.00 0 -99.000 0 -99.00 0 -99.00 0 -99.00 207 22 22 25.3 7.3508 32.3300 25.2946 56.5 89.1 6.91 301.0 0.770 -99.0000 0 -99.00 0 -99.000 0 -99.00 0 -99.00 0 -99.00 206 21 21 50.3 7.3374 32.3301 25.2965 56.7 89.2 6.90 300.6 0.830 -99.0000 0 -99.00 0 -99.000 0 -99.00 0 -99.00 0 -99.00 205 20 20 75.5 7.3327 32.3297 25.2968 57.0 89.8 6.89 299.9 0.787 -99.0000 0 -99.00 0 -99.000 0 -99.00 0 -99.00 0 -99.00 204 19 19 101.4 7.2700 32.4055 25.3650 58.7 92.9 6.65 289.8 0.364 -99.0000 0 -99.00 0 -99.000 0 -99.00 0 -99.00 0 -99.00 203 18 18 126.1 6.6445 33.1695 26.0501 59.9 95.3 5.06 220.4 0.078 -99.0000 0 -99.00 0 -99.000 0 -99.00 0 -99.00 0 -99.00 202 17 17 150.6 6.3794 33.5786 26.4072 59.8 95.2 4.17 181.4 0.065 -99.0000 0 -99.00 0 -99.000 0 -99.00 0 -99.00 0 -99.00 201 16 16 175.3 6.1978 33.6937 26.5213 59.9 95.1 3.83 166.6 0.060 -99.0000 0 -99.00 0 -99.000 0 -99.00 0 -99.00 0 -99.00 200 15 15 200.7 5.8502 33.7709 26.6259 59.9 95.2 3.36 146.2 0.061 -99.0000 0 -99.00 0 -99.000 0 -99.00 0 -99.00 0 -99.00 199 14 14 249.2 5.2513 33.8192 26.7360 60.1 95.4 2.63 114.4 0.053 -99.0000 0 -99.00 0 -99.000 0 -99.00 0 -99.00 0 -99.00 198 13 13 301.2 4.8345 33.8631 26.8184 60.1 95.4 2.08 90.4 0.052 -99.0000 0 -99.00 0 -99.000 0 -99.00 0 -99.00 0 -99.00 197 12 12 401.0 4.3975 33.9755 26.9554 60.4 96.0 1.26 54.7 0.051 -99.0000 0 -99.00 0 -99.000 0 -99.00 0 -99.00 0 -99.00 196 11 11 600.3 3.9825 34.1419 27.1311 60.6 96.3 0.57 24.8 0.050 -99.0000 0 -99.00 0 -99.000 0 -99.00 0 -99.00 0 -99.00 195 10 10 801.4 3.5414 34.2844 27.2886 60.5 96.1 0.29 12.7 0.050 -99.0000 0 -99.00 0 -99.000 0 -99.00 0 -99.00 0 -99.00 194 9 9 1000.5 3.1810 34.3638 27.3863 60.5 96.2 0.27 11.8 0.051 34.3609 0 -99.00 0 -99.000 0 -99.00 0 -99.00 0 -99.00 193 8 8 1251.4 2.7179 34.4417 27.4904 60.5 96.3 0.37 15.9 0.050 34.4398 6 -99.00 0 -99.000 0 -99.00 0 -99.00 0 -99.00 192 7 7 1501.9 2.3849 34.4998 27.5654 60.5 96.4 0.59 25.7 0.049 34.5033 0 -99.00 0 -99.000 0 -99.00 0 -99.00 0 -99.00 191 6 6 1751.9 2.1517 34.5417 27.6181 60.6 96.5 0.90 39.0 0.048 34.5437 0 -99.00 0 -99.000 0 -99.00 0 -99.00 0 -99.00 190 5 5 2000.8 1.9471 34.5809 27.6658 60.6 96.6 1.30 56.5 0.047 34.5829 0 -99.00 0 -99.000 0 -99.00 0 -99.00 0 -99.00 189 4 4 2251.0 1.8311 34.6049 27.6940 60.7 96.7 1.61 69.7 0.045 34.6076 0 -99.00 0 -99.000 0 -99.00 0 -99.00 0 -99.00 188 3 3 2501.2 1.7245 34.6257 27.7188 60.7 96.8 1.93 83.8 0.045 34.6277 0 -99.00 0 -99.000 0 -99.00 0 -99.00 0 -99.00 187 2 2 3002.2 1.6199 34.6480 27.7446 60.5 96.7 2.35 102.3 0.044 34.6492 6 -99.00 0 -99.000 0 -99.00 0 -99.00 0 -99.00 186 1 1 3358.4 1.6228 34.6527 27.7481 60.2 96.1 2.44 105.9 0.044 -99.0000 0 -99.00 0 -99.000 0 -99.00 0 -99.00 0 -99.00
