- Parameter or Variable: Ship speed in meters per second; Abbreviation: SHIP_SPEED; Unit: m/c; In-situ / Manipulation / Response variable: in-situ.
- Parameter or Variable: SST; Abbreviation: SST; Unit: DEG_C; Controlled vocabulary name: SEA SURFACE TEMPERATURE; In-situ / Manipulation / Response variable: in-situ; Analyzing instrument: Sea surface temperature measured by a SBE-45 thermosalinograph, in degrees Celcius; Detailed sampling and analyzing information: Seawater temperature and salinity were measured using a SBE-45 thermosalinograph, pumped at 1.5 l/min. The temperature offset listed in the header of the data file is the difference between the water temperature measured by the continuous-flow system (SBE-45, intake depth =~0.5m) and profiler package (SBE-49) water temperature at 0.5m. This offset has been subtracted from the water temperature data in this file, and corrections to in-situ temperature have been applied to the pCO2 data in this file. Accuracy of the SBE-45 is verified to less than 0.005 degC. Accuracy of the SBE-45 is verified to less than 0.005 salinity. Accuracy of the SBE-49 is verified to less than 0.0003 degC..
- Parameter or Variable: SSS; Abbreviation: SSS; Controlled vocabulary name: SALINITY; In-situ / Manipulation / Response variable: in-situ; Analyzing instrument: Sea surface salinity measured by a SBE-45 thermosalinograph, on the Practical Salinity Scale; Detailed sampling and analyzing information: Seawater temperature and salinity were measured using a SBE-45 thermosalinograph, pumped at 1.5 l/min. The temperature offset listed in the header of the data file is the difference between the water temperature measured by the continuous-flow system (SBE-45, intake depth =~0.5m) and profiler package (SBE-49) water temperature at 0.5m. This offset has been subtracted from the water temperature data in this file, and corrections to in-situ temperature have been applied to the pCO2 data in this file.

- Parameter or Variable: ATM_PRE; Abbreviation: ATM_PRE; Unit: HPA; Controlled vocabulary name: BAROMETRIC PRESSURE; In-situ / Manipulation / Response variable: in-situ; Detailed sampling and analyzing information: Barometric pressure from either onboard barometer, in hectopascals. Average daily pressure was used to fill missing measurements..
- Parameter or Variable: XCO2_WAT; Abbreviation: XCO2_WAT; Unit: PPM; Controlled vocabulary name: Mole fraction of CO2 (dry) in equilibrator headspace at equilibrator temperature, in parts per million; In-situ / Manipulation / Response variable: in-situ; Detailed sampling and analyzing information: CO2 Analyzer: LI-840A (Li-cor Biosciences Inc, Lincoln NE). Drying method: Nafion selectively permeable membrane drying loop (Perma Pure, Toms River NJ) operated in a reflux arrangement (no counter-flowing nitrogen stream). Equilibrator type: Three-chamber fast-rate equilibrator similar to that of Wanninkhof and Thoning (1993, reference below), flow rate 1.5 l/min. Note that equilibrator pressure was not measured. CO2 calibration standards: Two-point calibration using ultrapure nitrogen and a mixture of CO2 in nitrogen. Mixtures of CO2 in nitrogen, analyzed to within +/- 1%, were obtained from Scott-Marrin Inc (Riverside, CA). These standards are then adjusted based on comparison to a series of standards ranging from 378-515 ppmv obtained from NOAA/ESRL (http://www.esrl.noaa.gov/). CO2 span concentration range: 514.7.
