OXY-1: Sample over-titrated Sample_Number 934: ALL: Niskin top end cap was not seated properly. Analysis methods: ----------------- 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 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 ~6 weeks after the cruise. 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. Precision Statement: Chlorophyll values ranged from 0.02-4.76ug/l in 152 samples. Average %CV for this cruise was 4.06% with 2 out of 42 duplicate pairs having a CV>10% and 0 out of 42 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 see worksheet “CV%” in file QF2018-040CHL*.xls. 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 QF2018-040OXY*.xls. Salinity samples were collected in 200 mL type ll glass bottles with disposable nylon inserts and screw caps supplied by Ocean Scientific International Limited. 14 samples were analyzed at the Institute of Ocean Sciences in a temperature- controlled lab on a Guildline 8400B Salinometer (#68572) about 4 weeks after collection. The salinometer then malfunctioned so the remainder of the samples were analyzed off-site at AML using another Guildline 8400B Salinometer. Those samples were analyzed between 61 and 76 days after collection. No details are available regarding the conditions under which the samples were analyzed at AML or the condition of the instrument itself. All samples analyzed on instrument #68572 are flagged 2 with a comment. For details including a duplicate analysis, see document QF2018-040SAL*.xls. Nutrient samples were collected in plastic tubes and quick frozen in aluminum blocks stored in -20 freezer. One set of samples was collected and frozen immediately. Another set of samples from 400m 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. They were analyzed using an Astoria analyzer following methods described in IOS Nutrient Methods (1996) Barwell-Clarke and Whitney. For details including a duplicate analysis, see document QF2018-040nuts*.xls. 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 on to a Tenax TA trap kept at -80C. The trap was subsequently desorbed at 100 deg C (with a dewar containing boiling water) onto a Choromasorb 330 column which eluted onto a Flame Photometric Detector (FPD). All samples were run as soon as possible after being collected. For more detail see file "2018-040DMS report.doc" and for data and duplicate analysis see "DMS summary (2018-040).xls." The minimum detectable level for DMS is 0.10 nmol/L, so “0” values should be interpreted as <0.1nmol/L. DMSP-D: 20-75mL of seawater is drained from the niskin into a magnetic filtration funnel containing a 0.7 µM GF/F filter. The first 3.5 mL from the funnel is collected in a polypropylene tube containing 50µL of H2SO4 (50%). A new funnel and filter are used for each sample. DMPS-T: 3.5 mL of seawater is collected directly from the Niskin into a polypropylene tube containing 50µL of H2SO4 (50%) 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 later at the Institute of Ocean Sciences. The minimum detectable level is 0.1 nM, so “0” values should be interpreted as <0.1 nM.

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. Dissolved oxygen was calibrated using the method described in SeaBird Application Note #64-2, June 2012 revision, except that a small offset in the fit was allowed.
