  • Parameter or Variable: Dissolved Inorganic Carbon; Abbreviation: TCARBN; Unit: UMOL/KG; Observation type: discrete; Measured or calculated: Measured; Sampling instrument: Niskin Bottles; Analyzing instrument: SOMA; Detailed sampling and analyzing information: The two DICE systems (AOML 3 and AOML 4) were set up in a seagoing container modified for use as a shipboard laboratory on the aft main working deck of the R/V Roger Revelle.; Replicate information: 568 replicate sample analysis made. Average difference from the mean was 0.70. No systematic differences between the replicates were observed. DICE 1: 0.64 DICE 2: 0.75; Standardization description: The stability of each coulometer cell solution was confirmed three different ways. 1) Gas loops were run at the beginning and end of each cell; 2) CRM’s supplied by Dr. A. Dickson of SIO, were measured near the beginning; and 3) Duplicate samples were typically run throughout the life of the cell solution. Each coulometer was calibrated by injecting aliquots of pure CO2 (99.999%) by means of an 8-port valve (Wilke et al., 1993) outfitted with two calibrated sample loops of different sizes (~1ml and ~2ml). The instruments were each separately calibrated at the beginning of each cell with a minimum of two sets of these gas loop injections and then again at the end of each cell to ensure no drift during the life of the cell. These standard loops were consistent throughout the cruise.; CRM batch number: 152: Certified Value = 2020.88 µmol/kg; Poison name: 0.16 ml of saturated HgCl2 used for sample preservation; Poison correction: he sample bottles was 288 ml (calibrated by Esa Peltola, AOML). ; Uncertainty: Approximately 12% of the niskins sampled were duplicates taken as a check of our precision. These replicate samples were interspersed through- out the station analysis for quality assurance and integrity of the coulometer cell solutions. The average absolute difference from the mean of these replicates is 1.51 μmol/kg - No major systematic differences between the replicates were observed. The accuracy of the DICE measurement is determined with the use of standards (Certified Reference Materials (CRMs), consisting of filtered and UV irradiated seawater) supplied by Dr. A. Dickson of Scripps Institution of Oceanography (SIO). The CRM accuracy is determined manometrically on land in San Diego and the DIC data re- ported to the data base have been corrected to this batch 152 CRM value. The CRM certified value for this batch is 2020.88 μmol/kg1.; Method reference: Johnson, K.M., A.E. King, and J. McN. Sieburth (1985): “Coulometric DIC analyses for marine studies: An introduction.” Mar. Chem., 16, 61-82.; Researcher name: Rik Wanninkhof; Researcher institution: NOAA/AOML.
  • Parameter or Variable: Total alkalinity; Abbreviation: ALKALI; Unit: UMOL/KG; Observation type: discrete; Measured or calculated: Measured; Type of titration: two-stage open cell acidimetric, potentiometric; Cell type (open or closed): open cell titration; Detailed sampling and analyzing information: Samples are analyzed using an open cell titration procedure using two 250 mL jacketed cells. One sample is un- dergoing titration while the second is being prepared and equilibrating to 20°C for analysis. After an initial aliquot of approximately 2.3-2.4 mL of standardized hydrochloric acid (~0.1M HCl in ~0.6M NaCl solution), the sample is stirred for 5 minutes while air is bubbled into it at a rate of 200 scc/m to remove any liberated carbon dioxide gas. A Metrohm 876 Dosimat Plus is used for all standardized hydrochloric acid additions. After equilibration, ~19 aliquots of 0.04 ml are added. Between the pH range of 3.5 to 3.0, the progress of the titration is monitored using a pH glass electrode/reference electrode cell, and the total alkalinity is computed from the titrant volume and e.m.f. measure- ments using a non-linear least-squares approach ([Dickson2007]). An Agilent 34970A Data Acquisition/Switch Unit with a 34901A multiplexer is used to read the voltage measurements from the electrode and monitor the temperatures from th; CRM manufacturer: Dickson laboratory Certified Reference Material (CRM) ; CRM batch number: Batch 152 ; TA blank correction: N/A; Uncertainty: A total of 138 Niskin bottles were sampled for duplicate measurements and gave an average difference of 0.01 +/- 1.01 umol kg-1.; Method reference: Dickson, Andrew G., Chris Sabine and James R.
