Concentrations of dissolved organic carbon and phenols from Polarstern cruise PS 94-ARK-XXIX/3 from August to October 2015 (NCEI Accession 0278452)
This dataset contains chemical and physical data collected on R/V Polarstern during cruise ARK-XXIX_3 in the Arctic Ocean and Barents Sea from 2015-08-20 to 2015-10-07. These data include depth, dissolved organic Carbon, salinity calculated from CTD primary sensors, and water temperature. The instruments used to collect these data include Mass Spectrometer, Niskin bottle, and Shimadzu TOC-L Analyzer. These data were collected by Karl Kaiser of Texas A&M, Galveston as part of the "Development and application of a high sensitivity, ultra low volume method to measure biomarkers of terrigenous organic matter in the open ocean (Lignin phenol method development)" project. The Biological and Chemical Oceanography Data Management Office (BCO-DMO) submitted these data to NCEI on 2019-06-04.

Supplemental Information | Acquisition Description: Samples were filtered straight from Niskin bottles following established protocols for trace-metal clean sampling (Sample handling protocols for GEOTRACES cruises). Samples for DOC concentration were acidified to pH 2.5 and analyzed by high-temperature combustion on a Shimadzu TOC-L. DOC was calculated as the mean of between three and five injections using a six-point standard curve. Lignin-derived phenols were determined following Yan and Kaiser (2018; Anal. Chem), and Yan and Kaiser (2018; Analytica Chimica Acta). Briefly, C18 extracts were redissolved in 200 μL of 1.1 mol L−1 argon- sparged (10 min) NaOH in a 400 uL Teflon vial (Savillex Corp) and amended with containing 500 mg CuO, and amended with 10μL of10 mmolL−1 CuSO4 and 10μ L of 0.2 molL−1 ascorbic acid. Oxidation was at 150 C for 120 minutes. Following oxidation, the samples were spiked with with a surrogate standard mixture of p- hydroxybenzoic acid-13C7, vanillin-13C6, and syringaldehyde-13C6 and acidified to pH ≈ 2.5 with 6 mol L−1 sulfuric acid in the reaction vials. Clean-up of samples was performed with Waters HLB cartrides and final sample eluates were dried under ultra-high purity argon. Phenols were quantified by liquid chromatography/electrospray ionization-tandem mass spectrometry using a five-point calibration curve bracketing the concentration range. Quantified phenols (TDLP included vanillin, acetovanillone, vanillic acid, syringaldehyde, acetosyringone, syringic acid, coumaric acid, ferulic acid, p-hydroxy-benzaldehyde, p-hydroxy-acetophenone, and p-hydroxy-benzoic acid.
