They were analyzed in a temperature-controlled lab on a Guildline 8400B Salinometer standardized with IAPSO standard seawater within 104 - 107 days after collection. For details, see document QF2021-032SAL*.xlsx. Nutrient samples were collected in plastic tubes and quick frozen in aluminum blocks stored in a -20C freezer. 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, J. and F. Whitney. For details see document QF2021-032_NUTS*.xlsx. HPLC samples were filtered onto 47mm GF/F filters and stored at -80C prior to analysis. Samples were extracted in 95% methanol at -20C for 24 hours in the lab and analyzed on a WATERS 2695 HPLC separations system as detailed in Nemcek and Pena, 2014. Analysis was performed 2 months after collection. The average of two samples is reported. Variability is assessed as the %CV (std dev/mean*100) for duplicate pairs. All pigments below the limit of detection (LOD) are assigned a zero value. For details see document QF2021-032_HPLC*.xlsx. References: 1. Barwell-Clarke, J. and Whitney, F. 1996.

CTD salinity calibration appears to be within ±0.003psu. Larger errors will be present due to minor misalignment of temperature and conductivity when vertical salinity gradients are high. No recalibration was applied to the CTD salinity. Oxygen:Dissolved:SBE values cannot be confirmed as there was no calibration sampling for dissolved oxygen. Surface saturation values varied greatly. While the CTD fluorescence data are expressed in concentration units, they do not always compare well to extracted chlorophyll samples. For this cruise the CTD fluorescence data compared reasonably well with Tchl-a samples taken at the surface. For details on the processing see document: 2021-032_Processing_Report.doc. !-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-- ---27-- ---28-- ---29-- ---30-- ---31-- ---32-- ---33-- ---34-- ---35-- ---36-- ---37-- ---38-- ---39-- ---40-- ---41-- ---42-- 43 !Samp Pressu Depth Temperat Salinity Fluores Oxygen Oxyge Conductiv Salinity Fl Nitrat Fl Silica Fl Phospha Fl HPLC: HPLC: HPLC: HPLC: HPLC: HPLC: HPLC: HPLC: HPLC: HPLC: HPLC: HPLC: HPLC: HPLC: HPLC: HPLC: HPLC: HPLC: HPLC: HPLC: HPLC: HPLC: HPLC: HPLC:B- HPLC: Fl !le_ re ure: :T0:C0 cence: : n: ity: :Bottle ag e_ ag te ag te ag Chl-c3 Chlide- MgDVP Chl-c2 Chl-c1 Me- Peri But- Fuco Neo Pras Viola Hex- Diadino Allo Diato Zea Lut Gyr-de Chl-b c2-MGDG DVChl-a Chl-a Car TChl-a ag !Numb Primary URU: Dissol Disso Primary ~o plus_ ~t ~i ~p a chlide fuco fuco : !er Wetlabs ved: lved: tt Nitrit ri ca ha HP !
