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*". 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, about 4 months later in November 2015. Samples were analyzed on a three-channel Technicon Nutrient Auto Analyser, following methods described in Barwell-Clarke and Whitney (1996). For more detail see files “2015-07_SWL_Chem and Logs.xlsx” and "2015-07_NUTRIENTS report_SAQ*.docx" and "2015-07_Nutrients_IOS vs UMCES_*.xlsx." 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) For more detail see file “2015-07_SWL_Chem and Logs.xlsx” and file "2015-07_Nutrients_IOS vs UMCES_*.xlsx.". these data were received in Dec. 2016. 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) For more detail see file “2015-07_SWL_Chem and Logs*.xlsx”. 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. For more detail see file "DIC and ALK 2015-07_SWL_Chem and Logs_ DICAlk_added*.xlsx". and file “2015-07_SWL_Chem and Logs_DICAlk added.xlsx”. 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.

Since the analysts also used the consecutive CTD event numbers, no change was made to file names. There are notations in the log book in column "Watch Keepers" that contain the cast numbers that are used in these files for event numbers. See document "2015-007-event-number-guide.csv" to relate the two sets of event numbers. Transmissivity, Fluorescence: SeaPoint, PAR and PAR:Reference are nominal and unedited except that some records were removed in editing temperature and salinity. There was a problem with the primary system likely due to jellyfish parts getting into the tubing. The dissolved oxygen sensor was on the primary pump. All the data look bad and have been removed. The bottle comparison indicated salinity was reading low by about 0.001psu and a post-cruise calibration suggests it was high by <0.001psu. Delayed sample analysis and incomplete flushing of bottles where vertical gradients are high would both lead to higher bottle values, so that CTD salinity appears to be lower than it really is. No re-calibration was applied. For further processing details see the processing report 2015-007_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.
