All samples were returned to the Institute of Ocean Sciences and analyzed 3-5 weeks after the collection on a Turner Trilogy 7200-000 fluorometer, using methods described in Holm-Hansen et al (1965). Fluorescence readings taken before and after sample acidification were used to calculate chlorophyll and phaeopigment concentrations. For further details on methodology, see document QF2024-001_CHL*.xlsx Methodology sheet. NOTE: Flags and comments apply to chlorophyll values only. No flags or comments are assigned for Phaeo-Pigment values. Oxygen samples were analyzed at IOS immediately following the cruise using an automated Winkler titration system (Metrohm Dosimat model 876, 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 precision analysis, see document QF2023-001OXY*.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 4 - 13 days after collection. For details see document QF2024-001SAL*.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 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. For details including a duplicate analysis, see document QF2024-001nuts*.xlsx. References: 1. Barwell-Clarke, J. and Whitney, F. 1996. Institute of Ocean Sciences Nutrient Methods and Analysis.

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. There were 4 casts with calibration sampling for dissolved oxygen while sensor 4372 was in use; most of those samples came from areas where flushing of Niskin bottles is likely to be poor. Based on deep samples from sections where vertical DO gradients were fairly low, DO values were estimated to be low by about 2.2%. Recalibration was applied based on that estimate. For details on the processing see the report: 2024-001_Processing_Report.doc. ---------------------------------------------------------------------------------------------------- ---------------------------------------------------------------------------------------------------- The correction originally applied to DO sensor #4372 on CTD #0443 was found to be inappropriate. Results of COMPARE for 2024-006 and 2024-069 plus a post-cruise calibration showed unusual calibration drift for this sensor with CTD DO drifting to higher values. The results from inlets are too unreliable to estimate how much drift had occurred by March 2024, but there was likely to be some, so all SBE DO values were multiplied by 0.97 to cancel the earlier +2.2% correction and reduce values by a further 1% based on 2024-006 results. ---------------------------------------------------------------------------------------------------- *CALIBRATION $TABLE: CORRECTED CHANNELS !Name Units Fmla Pad Coefficients !-------------------------------- --------- ---- ------ ------------ Silicate umol/L 120 -99 (Salinity:T1:C1) (0.904 0.3E-02 25) Pressure decibar 10 -99 () (-1.1 1) Oxygen:Dissolved:SBE mL/L 10 -99 () (0 1.022) 'Oxygen:Dissolved:SBE [mL/L]' mL/L 10 -99 () (0 0.97) 'Oxygen:Dissolved:SBE [umol/kg]' umol/kg 10 -99 () (0 0.97) $END !1- 2- --3--- --4--- ---5---- --6-- --7-- ---8--- ---9--- ---10--- --11-- --12- ----13--- -14- -15- ---16--- 17 --18-- 19 --20-- --21-- 22 --23-- 24 ---25-- 26 !Bo Bo Pressu Depth Temperat Trans Trans Fluores Fluores Salinity Oxygen Oxyge Conductiv Numb Samp Salinity Fl Chloro Fl Phaeo- Nitrat Fl Silica Fl Phospha Fl !tt tt re ure: missi missi cence: cence: :T0:C0 : n: ity: er_o le_ :Bottle ag phyll: ag Pigmen e_ ag te ag te ag !~u ~u Primary vity vity: URU: URU: Dissol Disso Primary ~bin Numb ~o Extrac ~a t: plus_ ~t ~i ~p !mb en Green Seapoin Wetlabs ved: lved: _rec er tt ted ct Extrac Nitrit ri ca ha !er ce t SBE SBE ords le ed ted e te te te !-- -- ------ ------ -------- ----- ----- ------- ------- -------- ------ ----- --------- ---- ---- -------- -- ------ -- ------ ------ -- ------ -- ------- -- *END OF HEADER 11 11 1.3 2.4 8.1241 39.1 54.6 2.576 3.350 29.5126 6.14 268.1 3.11516 48 250 21.8001 0 -99.00 0 -99.00 -99.00 0 -99.00 0 -99.000 0 12 12 1.3 2.4 7.9751 39.4 54.7 2.819 3.335 29.1076 6.25 272.8 3.06470 241 251 -99.0000 0 -99.00 0 -99.00 -99.00 0 -99.00 0 -99.000 0 10 10 1.3 2.4 8.1308 36.3 51.7 2.536 3.473 29.5054 6.15 268.4 3.11500 50 249 -99.0000 0 4.54 6 1.20 10.15 0 22.42 0 1.077 0 9 9 4.1 5.1 8.4678 45.8 66.3 2.035 2.737 30.1653 5.74 250.5 3.20567 241 248 -99.0000 0 4.58 0 1.32 10.38 0 22.57 0 1.094 0 8 8 9.3 10.3 8.9111 53.1 81.0 0.612 1.055 30.7335 4.92 214.7 3.29745 241 247 -99.0000 0 2.04 6 1.16 15.58 0 28.79 0 1.465 0 7 7 24.6 25.5 9.0807 54.9 84.6 0.252 0.395 31.0377 4.57 199.3 3.34186 241 246 -99.0000 0 -99.00 0 -99.00 18.72 0 33.54 0 1.675 0 6 6 49.3 50.0 9.3092 55.0 84.9 0.110 0.148 31.3876 3.91 170.6 3.39640 241 244 31.4007 0 -99.00 0 -99.00 20.85 0 38.98 0 1.912 0 5 5 73.5 74.0 9.2131 54.6 84.3 0.089 0.120 31.4743 3.83 167.2 3.39763 241 243 -99.0000 0 -99.00 0 -99.00 21.46 6 41.06 6 1.987 6 4 4 99.4 99.6 8.4428 53.0 80.9 0.065 0.095 31.7090 2.92 127.3 3.35529 241 242 -99.0000 0 -99.00 0 -99.00 25.51 0 53.69 0 2.421 0 1 1 136.2 136.0 7.3391 42.7 61.7 0.049 0.092 32.0738 1.48 64.7 3.29650 42 239 -99.0000 0 -99.00 0 -99.00 -99.00 0 -99.00 0 -99.000 0 2 2 136.2 136.0 7.3390 43.0 61.6 0.054 0.102 32.0738 1.48 64.7 3.29649 43 240 32.0664 0 -99.00 0 -99.00 -99.00 0 -99.00 0 -99.000 0 3 3 136.2 136.0 7.3382 42.9 61.9 0.053 0.096 32.0741 1.48 64.7 3.29645 241 241 -99.0000 0 -99.00 0 -99.00 28.30 0 66.76 0 2.791 0
