Dissolved inorganic carbon, total alkalinity, pH on total scale, water temperature, salinity and other variables collected from profile discrete observations using flow through pump, CTD, Niskin Bottles and other instruments during the F.G. Walton Smith CIOERT2017 cruise WS17135 (EXPOCODE 33WA20170515), in the Gulf of Mexico, Caribbean Sea and North Atlantic Ocean from 2017-05-15 to 2017-06-13 (NCEI Accession 0240205)

This dataset contains profile discrete measurements of dissolved inorganic carbon, total alkalinity, pH on total scale, water temperature, salinity and other variables collected from profile discrete observations using flow through pump, CTD, Niskin Bottles and other instruments during the F.G. Walton Smith CIOERT2017 cruise WS17135 (EXPOCODE 33WA20170515), in the Gulf of Mexico, Caribbean Sea and North Atlantic Ocean from 2017-05-15 to 2017-06-13. Increasing amounts of atmospheric carbon dioxide from human industrial activities are causing changes in global ocean carbon chemistry. Through the SOOP program we measure air and ocean surface pCO2 and take discrete samples of other carbon parameters. This effort is in support of the coastal monitoring and research objectives of the NOAA Ocean Acidification Program (OAP) and the Climate Program Office.

Remarks The volume correction was applied due to added HgCl2 (Measured DIC*1.00037). The first CRM of each cell was used for a CRM correction. The DIC instruments were stable: the gas loop and CRM values did not change significantly throughout the life span of each cell. The samples were analyzed using the DICE (AOML 3 and AOML 4) and a new coulometer from UIC, Inc. CM5015 with CM5011 emulation software.; CRM manufacturer: Dr. A. Dickson of UCSD; CRM batch number: Batch 153; Preservation method: saturated HgCl2; Preservative volume: 0.2 ml; Quality flag convention: WOCE quality control flags are used: 2 = good value, 3 = questionable value, 4 = bad value, 5 = value not reported, 6 = mean of replicate measurements, 9 = sample not drawn.; Researcher name: Rik Wanninkhof, Leticia Barbero; Researcher institution: Atlantic Oceanographic and Meteorological Laboratory, National Oceanic and Atmospheric Administration (NOAA).
  • Parameter or Variable: Total alkalinity; Abbreviation: TA; Unit: micro-mol/kg; Observation type: Surface discrete and profile measurement (flow through and CTD, Niskin Bottles); In-situ / Manipulation / Response variable: In-situ observation; Measured or calculated: Measured; Sampling instrument: flow through system and CTD, Niskin Bottles; Type of titration: Full Titration; Cell type (open or closed): Open; Curve fitting method: Least-Square Analysis; Detailed sampling and analyzing information: Analysis dates: 12-13 October, 2017, 16-17 October, 2017 Titration system used: Open cell CRM Batch 153, Salinity = 33.325, cert. TA = 2225.59μmol/kg. One CRM was analyzed before the samples and another CRM or same CRM was run at the end of analysis for each system. The TA for the water samples was corrected using the daily averaged ratios between the certified and measured values of the CRMs run on each cell. The following table shows the CRM measurements for each day and cell.; CRM manufacturer: Dr. A.

  • Parameter or Variable: pH on total scale at 20C; Abbreviation: pH_TS_20C; Observation type: discrete; In-situ / Manipulation / Response variable: at 20C; Measured or calculated: Measured; Sampling instrument: Niskin bottles; Analyzing instrument: Spectrophotometer used: HP Agilent 8453; Detailed sampling and analyzing information: The equations of Liu et al, 2011 formulated using the purified m-cresol purple indicator was used to determine pH of the samples. pH samples were analyzed at 200C at Full Scale (pH 0-14) and reported at 25°C. Temperature for each sample was kept constant with a water bath connected, jacketed cell. Temperature was measured in the return flow to the water bath using a Hart Scientific Fluke 1523 reference thermometer after a 1.5 minute equilibration period. An experimentally determined temperature offset was applied to the measured temperature. A CRM (Batch 153) was measured before each set of samples for the day to help determine day to day variability. Approximately 80 mL of sample was extracted from each DIC sample bottle by an automated syringe immediately before DIC analysis to determine the pH.; Uncertainty: plus or minus 0.001 degrees celsius; Researcher name: Rik Wanninkhof; Researcher institution: Atlantic Oceanographic and Meteorological Laboratory, National Oceanic and Atmospheric Administration (NOAA).
