They were analyzed in a temperature-controlled lab on a Guildline 8400B Salinometer (S/N 68572) standardized with IAPSO standard seawater 3.5 to 4 months after collection. Calculated Standard pool of the mean (Sp) was 0.0024 using 20 out of 21 replicates. The unused replicates were rejected using the Chauvenet criteria. For more detail see file "SWL2015-07 Salt*". 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 QF2016-17OXY*.xls. There are two sets of nutrient samples. The following comments refer to channels Nitrate_plus_Nitrite, Silicate and Phosphate; these data were analyzed at the Institute of Ocean Sciences. Nutrient samples were collected in polystyrene tubes, quick frozen in aluminum blocks and stored in -20°C freezer until analysis at IOS. -Most samples were analyzed about 7 months later in February 2017 on a three-channel Technicon Nutrient Auto Analyser. Those samples are indicated by the Analysis_Method channel entry 1. -Some samples were partly thawed prematurely when a freezer was disconnected, so they were analyzed between Nov 23rd and Dec 13th, 2016 using an Astoria analyzer. Those samples are indicated by the Analysis_Method channel entry 2. All IOS analyses were done following methods described in Barwell-Clarke and Whitney (1996). There are two sets of nutrient samples. The following comments refer to channels Nitrate_plus_Nitrite2, Silicate2 and Phosphate2 and Ammonium: Nutrient samples (nitrate+nitrite, orthophosphate,silicate and ammonium) were analyzed at Chesapeake Biological Laboratory of the University of Maryland Center for Environmental Science (CBL-UMCES, http://www.umces.edu/nutrient-analytical-services-laboratory ). They were filtered from the Niskin bottles using 0.45 µM nylon syringe filters and frozen at -20°C until analysis at UMCES. Samples were thawed for 2 weeks at 8 degrees C before analysis using a Technicon Bran & Luebbe AutoAnalyzer II, following these methods: Nitrate+Nitrite: Technicon Ind. Method No.158-71, 1977 and USEPA 1979 Method 353.2. Silicate: Technicon Ind. Method No.811-86T, 1986. Phosphate: Technicon Ind. Method No.155-71W, 1973, 1971 USEPA 1979 Method 365.1 and Froelich, 1978. NH4: References Standard Methods 4500-NH3 G-1997 (for further details, see CBL-UMCES_Ammonium Method 2017-3_3.pdf) Data provided by Lee Cooper (UMCES) Oxygen isotopic analysis water samples were collected in 10 or 20 mL glass scintillation vials, sealed with Polyseal caps and wrapped with Parafilm as a precaution to prevent evaporation and isotopic fractionation. Samples were returned to the Chesapeake Biological Laboratory of the University of Maryland Center for Environmental Science. Water samples were analyzed by equilibration with carbon dioxide using a Thermo Fisher Gas Bench II peripheral linked to a continuous flow Delta V Plus isotope ratio mass spectrometer. The oxygen isotope composition is referenced to Vienna-Standard Mean Ocean Water (V-SMOW): (V-SMOW): d18O = ((Rsample-Rstandard) / Rstandard) *1000 per mille, where R=18O/16O and V-SMOW is Vienna Standard Mean Ocean Water, as distributed by the International Atomic Energy Agency. Analytical precision was better than ±0.1 per mille and was assessed by analysis of in-house water standards during sample analysis and calibration to international water isotope standards (V-SMOW, V-SLAP, GISP). Data corrections were made based upon analysis of the in-house standards relative to international standards, which were normalized as per recommendations of Paul et al. [2007]. Data provided by Lee Cooper (UMCES) DIC/Alkalinity samples were collected in 250 mL glass reagent bottles, preserved with HgCl2, sealed with grease and stored at 4°C, until analysis at IOS about 7 months after collection. Samples were first analysed for DIC on a SOMMA-1 (Single-Operator Multi-Metabolic Analyzer), a computer controlled automated dynamic headspace analyser. The coulometer system is similar to that described by Johnson et al (1993) and was calibrated with Dickson CRM seawater (Batch 152 with a concentration of 2216.94 µmol/kg) (DOE 1994; Dickson 2001; Dickson et al. 2003) supplied by Andrew Dickson (Scripps Institute of Oceanography, San Diego, USA). Samples were then analyzed for alkalinity by means of potentiometric titration using 0.1N HCl/0.6N NaCl, using a program written by Paul Covert, PMEL, University of Washington which is based on Andrew Dickson’s, SCRIPPS system. There are three sets of extracted chlorohpyll samples. The following comments refer to Chlorophyll:Extracted These samples were collected between Victoria and Dutch Harbor. Samples were filtered onto 25mm GF/F filters and stored in glass scintillation vials at -20C pior to analysis which was done at the Institute of Ocean Sciences on August 8 & 9, 2016. Samples were extracted in 90% HPLC grade acetone at -20C for 24 hours 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 within 5 weeks of 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. There are 3 sets of extracted chlorohpyll samples. The following comments refer to Chlorophyll:Extracted2 These samples were collected between Dutch Harbour and Barrow. Chlorophyll samples were filtered onto 25mm GF/F filters and stored in glass scintillation vials. Filters were frozen at -20°C initially to fracture cell membranes, then 10 mL of 90% acetone was added and samples stored in the dark for 24 hours at 2°C. Chlorophyll concentration in acetone was then analyzed shipboard on a Turner 10AU fluorometer without acidification (Welschmeyer, 1994). The fluorometer was calibrated with a pure chlorophyll-a standard obtained from Turner Designs, (Turner Designs Part No.10-850) before and after all sampling, with use of a secondary solid standard (Part No.10-AU-904) during sampling to identify any possible instrument drift. Data provided by Lee Cooper (UMCES). There are 3 sets of extracted chlorohpyll samples. The following comments refer to Chlorophyll:Extracted3 These samples were collected between Dutch Harbour and Barrow. The following comments refer to Chlorophyll:Extracted3 These samples were provided by K. Frey, Clark University (July 25, 2016). Suspended Particulate Material: To measure SPM, 0.7 µm GF/F glass fiber filters were rinsed with 500 mL of Milli-Q (18 O) water, dried, combusted (4-6 hours at 450 °C), and pre-weighed. SPM samples were filtered using 1000 mL of seawater. Samples were then dried at 55 °C for at least an hour before being sealed and shipped to Clark University to be re-weighed. Data provided by K. Frey, Clark University (July 25, 2016). Water samples for chromophoric dissolved organic carbon (CDOM) analysis were filtered using pre-rinsed (10% HCl and then Milli-Q (18 O-ohms) water) 0.2 µm Whatman nuclepore polycarbonate track-etched membranes immediately after rosette sampling. CDOM samples were stored in the dark at 4ºC in acid washed (10% HCl), pre-combusted (450°C for 6 hours) foil-covered Qorpack clear glass bottles and analyzed shipboard within 24 hours. Data provided by K. Frey, Clark University (July 25, 2016). For more detail on rosette sampling see file 2016-17_SWL_Chem and Logs*.xlsx. References: 1. Barwell-Clarke, J. and Whitney, F. 1996.

Transmissivity, Fluorescence: SeaPoint, PAR and PAR:Reference are nominal and unedited except that some records were removed in editing temperature and salinity. Channel Oxygen:Dissolved:SBE was recalibrated based on bottles samples taken in the Pacific Ocean section of the cruise. The bottle comparison indicated that the salinity was low by about 0.0055psu but the standard deviation in the fit was 0.008psu. The delay in analysis and poor flushing may account for the difference and noisy fit. The post-cruise calibration indicated that it was low by ~0.0015psu. Calibration is likely within 0.002psu, but larger errors are expected due to minor misalignment in the presence of large vertical temperature gradients, especially near the surface. There were many unstable features in T-S space in the top 50m to 100m that are associated with local minima in the descent rate, but those minima are often not so low that we expect to see corruption by shed wakes. Since they are seen in both temperature sensors the problem is likely not due to sensor malfunction. They are seen in a variety of regions from the Pacific to Arctic, so are not believed to caused by active mixing. In the Chukchi Sea section of the cruise the salinity data was sometimes noisy in sections where temperature was quite steady leading to some unstable features. For further processing details see the processing report 2016-017_Processing_Report.doc. --------------------------------------------------------------------------------------- This research cruise is part of the Distributed Biological Observatory (DBO) programme, which is an international effort to make repeat oceanographic observations at chosen stations in the Bering and Chukchi Seas and in Barrow Canyon. It is also a continuation of the Canada Three Oceans project “C3O” which was part of Canada’s contribution to the International Polar Year (IPY) research effort. Collaborators include University of Maryland, Center for Environmental Science (UMCES), Clark University and NOAA in the US and the University of Victoria and the University of British Columbia in Canada. Principle investigator Lee Cooper (UMCES) has provided nutrients, O18 and Chl-a data to be included in the chemistry data set. --------------------------------------------------------------------------------------- *CALIBRATION $TABLE: CORRECTED CHANNELS !
