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 ~4 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 0.01-8.51ug/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 see worksheet “CV%” in file QF2018-01CHL*.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 QF2018-01OXY*.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. They were analyzed in a temperature-controlled lab on a Guildline 8400B Salinometer standardized with IAPSO standard seawater 13 - 30 days after collection. For details including a duplicate analysis, see document QF2018-01SAL*.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 QF2018-01nuts*.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 "2018-01DMS report.doc" and for data and duplicate analysis see "DMS summary (2018-01).xls." The minimum detectable level for DMS is 0.10 nmol/L, so “0” values should be interpreted as <0.1nmol/L. DOC, TOC, TDN, and TN samples were collected in precombusted 40 mL glass vials and acidified immediately with 100 uL of 4M HCl. DOC/TDN samples were filtered inline from the Niskin bottles, using acid-washed filter holders and tubing and pre-combuted GF/F filters. DOC/TDN samples were collected for depths <250 meters, and TOC/TN samples were collected for depths >250 meters. The full data set may be found in document LineP-DOC-TOC-TN-TDN.xlsx. For details on analysis of Dissolved inorganic carbon (DIC) and Total alkalinity (Alk) refer to: https://www.ncei.noaa.gov/access/metadata/landing-page/bin/iso?id=gov.noaa.nodc:0225534. All Alkalinity samples flagged 3 due to poor precision and accuracy in analysis. References: 1. Barwell-Clarke, J. and Whitney, F. 1996. Institute of Ocean Sciences Nutrient Methods and Analysis.

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.
