  • Parameter or Variable: Dissolved Inorganic Carbon; Abbreviation: DIC_umol/kg; Unit: umol/kg; Observation type: Profile; In-situ / Manipulation / Response variable: In-situ observation; Measured or calculated: Measured; Calculation method and parameters: none; Sampling instrument: Niskin bottle, borosilicate glass BOD bottle; Analyzing instrument: Apollo ScTech AS-C2; Detailed sampling and analyzing information: Discrete samples were collected from Niskin bottles and transferred to sample bottles through silicone tubing to prevent bubbling. Samples for pH, total alkalinity, and DIC were transferred without bubbling into 60-ml or 125-ml glass BOD bottles with greased stoppers. These were filled to leave less than 1 % headspace in the bottle, preserved with 0.1 ml of saturated mercuric chloride solution, and immediately cooled. Samples for total alkalinity/pH and DIC were generally stored for several weeks before analysis, allowing for settling of particulate material, with the supernatant sample drawn for analysis. DIC was measured first from each sample bottle, followed sequentially by pH and TAlk. DIC of unfiltered water was determined using an automated analyzer built by Apollo SciTech (Bogart, GA). Immediately after opening the sample bottle, a digital syringe withdrew a small amount of sample (0.5 mL), acidified it with 10 % phosphoric acid and subsequently measured the evolved CO2 with a Li-Cor 6262 non-dispersive infrared gas analyzer; Standardization description: Certified seawater reference materials from Dr. A. Dickson were used to determine DIC concentration by preparing a calibration curve covering the range of DIC from 200 to 2000 ummol/kg, with a resulting precision ranging from 0.05 to 0.5 % (or 0.1-10 umol/kg ), with an average of ~0.1 % (2 umol/kg ).; Standardization frequency: daily; CRM manufacturer: Andrew Dickson's lab at Scripps Institute of Oceanography; CRM batch number: various; Preservation method: mercuric chloride; Preservative volume: 0.1 mL; Quality flag convention: 1=Not Sampled, 2=Good,; Researcher name: Joe Salisbury; Researcher institution: University of New Hampshire.
  • Parameter or Variable: Total alkalinity; Abbreviation: TA; Unit: umol/kg; Observation type: Profile; In-situ / Manipulation / Response variable: In-situ observation; Measured or calculated: Measured; Sampling instrument: Niskin bottle, borosilicate glass BOD bottle; Analyzing instrument: Apollo SciTech AS-ALK2; Type of titration: Gran; Cell type (open or closed): Open; Detailed sampling and analyzing information: Discrete samples were collected from Niskin bottles and transferred to sample bottles through silicone tubing to prevent bubbling. Samples for pH, total alkalinity, and DIC were transferred without bubbling into 60-ml or 125-ml glass BOD bottles with greased stoppers. These were filled to leave less than 1 % headspace in the bottle, preserved with 0.1 ml of saturated mercuric chloride solution, and immediately cooled. Samples for total alkalinity/pH and DIC were generally stored for several weeks before analysis, allowing for settling of particulate material, with the supernatant sample drawn for analysis. DIC was measured first from each sample bottle, followed sequentially by pH and TAlk. TAlk was measured by Gran titration (Gran 1952) with 0.1 N HCl using an automated titrator. This method adds an initial aliquot of acid to the sample in an open cell, generally lowering the sample pHNBS below 3, and then adds subsequent aliquots of titrant until the pHNBS changes linearly with the volume of acid added. The TAlk endpoint is then obtained from linear regression of the change of pHNBS against the volume of acid added, according to a Gran transformation; Standardization description: Multiple analyses of the Dickson reference material resulted in a calculated precision of this method of about 0.1 % (or ~ plus/minus 2 mol kg-1 ). The accuracy of the TAlk utomated system, also calibrated with multiple batches of the Dickson CRM as discussed above, was plus/minus 3-4 umol kg-1.; CRM manufacturer: Andrew Dickson's lab at Scripps Institute of Oceanography; CRM batch number: various; Preservation method: mercuric chloride; Preservative volume: 0.1 mL; Quality flag convention: 1=Not Sampled, 2=Good,; Researcher name: Joe Salisbury; Researcher institution: University of New Hampshire.
  • Parameter or Variable: pH; Abbreviation: pH; pH scale: NBS; Observation type: Profile; In-situ / Manipulation / Response variable: In-situ observation; Measured or calculated: Measured; Sampling instrument: Niskin bottle, borosilicate glass BOD bottle; Analyzing instrument: AS_ALK2 with Orion 3-Star electrode, Thermo Fisher Inc.; Temperature of pH measurement: 24.4 oC; Detailed sampling and analyzing information: See above for sampling information. The pH electrode used in the TAlk titration (Orion 3-Star, Thermo Fisher Inc.) was calibrated using three low ionic strength pH buffers certified on the U.S. National Bureau of Standards (NBS) scale to plus/minus 0.01, and the initial reading before the addition of acid titrant was taken as the sample pHNBS (; Standardization description: 3 NBS standard plus/minus 0.01; Standardization frequency: daily; pH standard values: 4.01, 7.00, 10.01; Temperature of standardization: 24.4 oC; At what temperature was pH reported: 24.4 oC; Quality flag convention: 1=Not Sampled, 2=Good,; Researcher name: Joe Salisbury; Researcher institution: University of New Hampshire.
  • Parameter or Variable: pCO2 (fCO2) autonomous; Abbreviation: pCO2; Unit: uatm; Observation type: Surface Underway; In-situ / Manipulation / Response variable: In Situ observation; Measured or calculated: Measured; Sampling instrument: Gas equilibrator; Analyzing instrument: Li-cor LI840; Equilibrator type: Flow to the shipboard flow-through system was pumped to an equilibrator, similar to that described by Wanninkhof and Thoning (1993), but consisting of three Plexiglas chambers instead of a single chamber. Equilibrated air was drawn out of the third chamber, while ambient air was drawn into the first chamber and passed through the second and third chambers, equilibrating with the pumped water supply at each step; Equilibrator volume: ~6l; Is the equilibrator vented or not: vented; Water flow rate: >10 l/min; Gas flow rate: 0.1 L/min; How was temperature inside the equilibrator measured: not measured; How was pressure inside the equilibrator measured: not measured; Drying method for gas: Nafion selectively permeable membrane (Perma Pure, Toms River NJ) with a counterflowing stream of dry nitrogen, which dried the sample gas stream of water vapor; SEA CO2 gas detector manufacturer: Li-cor; Standardization technique: The Li-cor was calibrated several times each survey with pure nitrogen (0 ppm CO2 molar fraction) and one span tank. Over the study period we employed a succession of span tanks containing a gas mixture with CO2 molar fraction between 819 and 851 ppm (Scott-Marin, Riverside, CA); Standardization frequency: daily; Standard gas manufacturer: Scott-Marrin; Standard gas concentration: various; Water vapor correction method: Dickson et al. 2007; Temperature correction method: Dickson et al. 2007; At what temperature was pCO2 reported: in-situ; Quality flag convention: 1=Not Sampled, 2=Good,; Researcher name: Joe Salisbury; Researcher institution: University of New Hampshire.
