(deg min) WATER DEPTH : 3233 *INSTRUMENT TYPE : Sea-Bird CTD MODEL : SBE-911plus SERIAL NUMBER : 0443 *COMMENTS Sample Number 141: SAL:Bottle - liner of one duplicate not inserted completely. Value (34.5246) much higher than the other duplicate. Only one value is reported. Sample Number 142: OXY:Bottle - sample over-titrated and value recalculated. Sample Number 151: OXY:Bottle - sample over-titrated. Sample Number 158: SAL:Bottle - sample was originally mislabelled as 150. Analysis methods: ----------------- 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 within 13 - 30 days after collection. For details on duplicate analysis see file 2018-001_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 file 2018-001_OXY.pdf. Nutrient samples were collected in plastic tubes. One set of samples was collected and immediately quick frozen in aluminum blocks stored in -20 freezer. Another set of samples from 400 dbar and deeper (to be used for silicate analysis) was collected and stored at 4C in the dark. All samples were returned to IOS for analysis using an Astoria analyzer following methods described in IOS Nutrient Methods (1996) Barwell-Clarke and Whitney. For precision and duplicate analysis see file 2018-001_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 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 ~4 weeks after the cruise. When duplicate samples were collected the average of two samples is reported. Variability is assessed as the CV% (std dev / mean*100). Flags and comments apply to chlorophyll values only. No flags or comments are assigned for Phaeopigment values. Precision Statement: Chlorophyll values ranged from 0.01-8.51 µg/l. Average %CV for this cruise was 3.86% with 3 out of 56 duplicate pairs having a CV > 10% and 0 out of 56 duplicate pairs having a CV > 30%. Our average dataset %CV is 3.73% for 2013 - 2017 so the overall quality of this dataset is very good. For details on duplicates see file 2018-001_CHL.pdf. DMS samples were collected in 250 ml 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 ~100 ml/min. The DMS was extracted from the water and absorbed on to a Tenax TA trap kept at -80C. The trap was subsequently desorbed at 100C (with a Dewar containing boiling water) onto a Chromasorb 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 < 0.1 nmol/l. For more details see file 2018-001_DMS_report.pdf and for duplicate analysis see 2018-001_DMS.pdf. DMSP-D: 20-75 ml of seawater were allowed to flow directly from the Niskin into a magnetic filtration funnel containing a 0.7 µm GF/F filter. The first 3.5 ml were collected in a polypropylene tube containing 50 µl of a 50% sulphuric acid solution. DMPS-T: 3.5 ml of seawater were collected directly from the Niskin into a polypropylene tube containing 50 µl of a 50% sulphuric acid solution. DMSP-D and DMSP-T: Samples were stored in the dark at 4 degrees C for a minimum of 24 hours. They were hydrolized and analyzed later at the Institute of Ocean Sciences. The minimum detectable level is 0.1 nmol/l, so “0” values should be interpreted as < 0.1 nmol/l. For more details see file 2018-001_DMS_report.pdf. References: 1.

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. Oxygen:Dissolved:CTD was calibrated using the method described in Sea-Bird Application Note #64-2, June 2012 revision (Sea-Bird_64-2_Jun2012.pdf), except that a small offset in the fit was allowed. For details on the processing see the report: 2018-001-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 !Samp Bo Bo Pressu Temperat Salinity Sigma-t: Trans Oxygen Oxyge Fluores Salinity Fl Oxygen: Oxyge Fl Nitrat Fl Phospha Fl Silica Fl !le_ tt tt re:CTD ure:CTD :CTD CTD missi :Disso n:Dis cence: :Bottle ag Dissolv n:Dis ag e_plus ag te: ag te: ag !Numb ~u ~u vity: lved: solve CTD: ~o ed: ~ed:B ~o _Nitri ~o Bottle ~o Bottle ~o !er mb en CTD CTD: d:CTD Seapoin tt Bottle: ottle tt te: tt tt tt ! er ce Volume :Mass t le Volume :Mass le Bottle le le le !---- -- -- ------ -------- -------- -------- ----- ------ ----- ------- -------- -- ------- ----- -- ------ -- ------- -- ------ -- *END OF HEADER 159 24 1 3274.2 1.6601 34.6487 27.7421 60.5 2.31 100.3 0.060 -99.0000 0 -99.000 -99.0 0 -99.00 0 -99.000 0 -99.00 0 158 23 24 4.7 7.9948 32.5032 25.3401 46.5 6.68 290.7 0.239 32.5069 2 6.601 287.5 0 6.83 0 0.809 0 6.77 0 157 22 23 8.8 7.9894 32.5035 25.3411 47.1 6.67 290.6 0.361 -99.0000 0 6.588 286.9 0 6.87 0 0.804 0 6.63 0 156 21 22 25.5 7.9757 32.5068 25.3457 47.2 6.66 289.8 0.571 -99.0000 0 6.578 286.5 0 6.84 0 0.808 0 6.65 0 155 20 21 49.9 7.9882 32.5179 25.3526 46.9 6.63 288.6 0.725 -99.0000 0 6.608 287.8 0 6.86 0 0.802 0 6.63 0 154 19 20 75.8 8.0742 32.5473 25.3632 48.7 6.52 283.8 0.537 -99.0000 0 6.480 282.2 6 6.92 6 0.812 6 6.82 6 153 18 19 99.0 7.7951 33.3886 26.0641 49.9 4.31 187.4 0.121 -99.0000 0 4.286 186.5 0 21.37 0 1.587 0 24.68 0 152 17 18 125.4 7.7865 33.6661 26.2834 49.8 3.64 158.4 0.088 -99.0000 0 3.635 158.2 0 24.93 0 1.785 0 30.90 0 151 16 17 150.0 7.6339 33.8453 26.4462 50.1 3.15 137.0 0.076 -99.0000 0 3.156 137.3 2 27.81 0 1.957 0 36.88 0 150 15 16 174.6 7.2552 33.8980 26.5413 50.7 2.89 125.7 0.072 -99.0000 0 2.900 126.2 0 29.77 0 2.078 0 41.67 0 149 14 15 200.5 6.9271 33.9182 26.6024 51.1 2.60 113.3 0.072 -99.0000 0 2.607 113.4 0 31.48 0 2.205 0 46.76 0 148 13 14 250.3 6.1848 33.9439 26.7206 51.1 2.03 88.2 0.071 -99.0000 0 2.027 88.2 6 35.10 0 2.468 0 57.50 0 147 12 13 304.4 5.7558 33.9786 26.8017 51.8 1.54 66.8 0.071 -99.0000 0 1.578 68.6 0 37.50 0 2.650 0 65.37 0 146 11 12 399.8 5.2563 34.0298 26.9022 52.3 1.06 46.2 0.068 -99.0000 0 1.079 46.9 0 40.13 0 2.859 0 76.08 0 145 10 11 598.8 4.3179 34.1466 27.0998 53.7 0.51 22.0 0.067 -99.0000 0 0.506 22.0 0 43.14 0 3.082 0 100.25 0 144 9 10 800.0 3.7873 34.2769 27.2583 55.0 0.28 12.1 0.067 -99.0000 0 0.278 12.1 6 44.21 6 3.184 6 119.01 6 143 8 9 999.8 3.3285 34.3690 27.3766 55.9 0.26 11.1 0.067 34.3685 6 0.241 10.5 0 44.66 0 3.217 0 133.87 0 142 7 8 1250.7 2.8453 34.4368 27.4752 57.2 0.34 14.6 0.066 34.4371 0 0.330 14.3 2 44.90 0 3.201 0 148.06 0 141 6 7 1501.2 2.4301 34.5059 27.5665 59.0 0.63 27.5 0.065 34.5078 2 0.611 26.6 0 44.30 0 3.127 0 160.11 0 140 5 6 2001.9 1.9696 34.5827 27.6655 61.1 1.31 57.1 0.062 34.5858 0 1.306 56.7 0 42.59 0 2.986 0 171.75 0 139 4 5 2499.9 1.7331 34.6283 27.7203 60.9 1.92 83.6 0.061 34.6281 6 1.916 83.2 6 40.99 0 2.857 0 175.52 0 138 3 4 3001.5 1.6393 34.6477 27.7429 60.8 2.30 99.8 0.060 34.6503 0 2.301 100.0 0 39.96 0 2.774 0 174.33 0 137 2 3 3001.4 1.6393 34.6477 27.7429 60.8 2.30 99.9 0.060 34.6531 6 2.303 100.1 0 39.97 0 2.773 0 174.31 0 136 1 2 3275.2 1.6603 34.6486 27.7421 60.5 2.31 100.3 0.060 -99.0000 0 2.312 100.4 0 39.81 0 2.768 0 174.65 0
