Questionable. 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 ~2 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 0.04-26.35ug/l in 108 samples. Average %CV for this cruise was 3.56% with 2 out of 33 duplicate pairs having a CV>10% and 0 duplicate pairs having a CV>30%. Our average dataset %CV is 3.80% for 2013 - 2018 so the overall quality of this dataset is very good. For details see worksheet “CV%” in file QF2019-006CHL*.xlsx. 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 QF2019-006OXY*.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 31 - 50 days after collection. For details including a duplicate analysis, see document QF2019-006SAL*.xlsx. 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 QF2019-006nuts*.xlsx. 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 into a Tenax TA trap kept at -80C. The trap was subsequently desorbed at 100 deg C (with a dewar containing boiling water) onto a Chromosil 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 <0.1nmol/L. DMS data are limited to 2 significant figures. Unless otherwise indicated the % relative difference between duplicates is <20%. For more detail see file "2019-006 DMS report.doc" and for data and duplicate analysis see "QF 2019-006 DMS*.xlsx." DMSP-D: Approximately 50-75mL of seawater was allowed to flow directly from the niskin into a filtration funnel containing a 0.7um GF/F filter. The first 3.5mL was collected in a polypropylene tube (15mL) containing 50uL of a 50% sulphuric acid solution. DMPS-T: 3.5mL of seawater was collected directly from the niskin into a polypropylene tube (15mL) containing 50uL of a 50% sulphuric acid solution. 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. DMSP data are limited to 2 significant figures. Unless otherwise indicated the % relative difference between duplicates is <20%. For details on analysis and raw data, see document "QF2019-006 dmsp*.xlsx. DOC and TOC samples were collected in 80 mL polycarbonate bottles and frozen until analysis. DOC samples were filtered inline from the Niskin bottles, using acid-washed filter holders and tubing and pre-combusted Whatman 25 mm GF/C filters (~1.2 ?m pore size). For analysis, samples were thawed and acidified with 4M HCl at a ratio of 100 uL HCL to 40 mL seawater. DOC samples were collected for depths <250 meters, and TOC/TDN samples were collected for depths >250 meters. For full details on analysis and processing see: Johannessen, S., Fassbender, A.

Biological and Chemical Oceanography Data Management Office (BCO-DMO). https://www.bco-dmo.org/dataset/865829 Non-OSD researchers needing access to the data should send a request to: DFO.PACSCIIOSData-DonneesISOSCIPAC.MPO@dfo-mpo.gc.ca The following samples were collected on Cruise 2019-006. These were collected as part of the EXPORTS Program, in collaboration with Andrea Fassbender (NOAA). Cruise log and sampling logs are available upon request. Water samples for CDOM analysis were passed through a Millipore Opticap XL Durapore 0.22 µm inline filter cartridge (Product No. KVGLA04HH3) into 125 ml amber glass bottles, directly from the original Niskin bottles. Samples were refrigerated and returned to the Institute of Ocean Sciences, where they were analyzed within one year of collection. Spectral absorbance (280-700 nm at 1nm resolution) was measured with a HP Agilent 8453 spectrophotometer, using a quartz cell with a 10-cm pathlength. Absorbance, ACDOM (dimensionless), was converted to the absorption coefficient, aCDOM (m-1): aCDOM(l) = ACDOM(l)x2.303/pathlength, where l is wavelength (See Johannessen and Miller, 2001 and Stedmon et al., 2000). Spectral absorption was measured against a distilled water blank, but no offset correction was applied. Cruise logs, sampling logs and other data products from this cruise are available electronically on request from the IOS data archive (http://www-sci.pac.dfo-mpo.gc.ca/osap/data/default_e.htm) or from the authors.

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. 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. For details on the processing see the report: 2019-006_Processing_Report.doc. --------------------------------------------------------------------------------- Comments from secondary file: C:\Users\huntingtons\Desktop\Additions\Carbon Additions\2019-006\Processing\IOS\2019-006-0032.car --------------------------------------------------------------------------- Sample_Number 183: TOC: duplicate not sampled; CDOM: value not reported *CALIBRATION $TABLE: CORRECTED CHANNELS !
