  • Parameter or Variable: CTDTMP; Abbreviation: CTDTMP; Unit: DEG_C; Controlled vocabulary name: WATER TEMPERATURE; Observation type: CTD; In-situ / Manipulation / Response variable: in-situ observation; Detailed sampling and analyzing information: Temperature in °C. Measured with a Sea-Bird SBE3 Oceanographic Temperature Sensor. Lower CTD to 10m, then raise back to surface, wait for pump to start, then begin downcast.

  • Parameter or Variable: DISSOLVED INORGANIC CARBON (DIC); Abbreviation: TCARBN; Unit: UMOL/KG; Controlled vocabulary name: DISSOLVED INORGANIC CARBON (DIC); Observation type: discrete; In-situ / Manipulation / Response variable: in-situ observation; Detailed sampling and analyzing information: Dissolved Inorganic Carbon in µmmol/kg. Measured on discrete samples by coulometry with a UIC Inc CM-5010 coulometer. Samples are drawn into borosilicate glass bottles and the stopper is sealed with grease. Samples are preserved with HgCl2 saturated, kept in the dark in a cool location and returned to the laboratory for coulometric determination. The system is calibrated by 99.998 % CO2 gas at known temperature and pressure with two stainless steel loops of known volumes.
  • Parameter or Variable: partial pressure of carbon dioxide - watery; Abbreviation: PCO2; Unit: UATM; Controlled vocabulary name: partial pressure of carbon dioxide - water; Observation type: discrete; In-situ / Manipulation / Response variable: in-situ observation; Detailed sampling and analyzing information: Analyzed by gas chromatography with the flask equilibrator coupled to the GC. Samples are collected in 500 mL volumetric flasks with a screw cap. Samples are preserved with HgCl2 (0.4 ml) and analyzed ashore by equilibration at 4°C with a gas of known CO2 concentration followed by gas chromatography with a flame ionization detector.
  • Parameter or Variable: pCO2 temperature; Abbreviation: PCO2TMP; Unit: DEG_C; Controlled vocabulary name: pCO2 temperature; Observation type: discrete; In-situ / Manipulation / Response variable: in-situ observation
  • Parameter or Variable: Chlorofluorocarbon - 11, Chlorofluorocarbon - 113; Abbreviation: CFC-11, CFC113; Unit: PMOL/KG; Controlled vocabulary name: Chlorofluorocarbon - 11, Chlorofluorocarbon - 113; Observation type: discrete; In-situ / Manipulation / Response variable: in-situ observation; Detailed sampling and analyzing information: Water samples were collected using Niskin bottles. CFC samples were collected in 60 cm3 glass ampoules using a method adapted from Busenberg and Plummer (1992). The ampoules were filled directly from the Niskin bottles using a stainless steel filling tee (Bulsiewicz et al., 1998) and flushed with at least 120 cc of the water prior to flame sealing under continuously flowing ultra-high purity nitrogen. These samples were returned to Lamont-Doherty Earth Observatory where they were measured for CFC-11, CFC-12, and CFC-113 within a few months of collection. The measurements were carried out using a purge and trap system interfaced to a gas chromatograph with an electron capture detector (Bullister and Weiss, 1988; Smethie et al., 2000). Measurement precision was the larger of 1% or 0.01 pmol/kg for CFC-11, 2.5% or 0.01 pmol/kg for CFC-12, and 0.03 pmol/kg for CFC-113. The concentrations are reported on the SIO 93 calibration scale. pCFC-11, pCFC-12 and pCFC-113 are the partial pressures of these gases in the atmosphere at the time the water parcel was at the surface, assuming equilibrium between the surface water and the atmosphere. It was calculated by dividing the concentration in the water by the solubility of the gas reported by Warner and Weiss (1985) for CFC-11 and CFC-12 and Bu and Warner (1995) for CFC-113.
  • Parameter or Variable: 18O/16O ratio; Abbreviation: 18O/16O ratio; Unit: Per mille; Controlled vocabulary name: 18O/16O ratio; Observation type: discrete; In-situ / Manipulation / Response variable: in-situ observation; Detailed sampling and analyzing information: Water samples were collected using Niskin bottles. Samples for 18O were drawn into dark 60 ml glass bottles and screwed caps tightly sealed. Oxygen isotope measurements were carried out at the Institute of Earth Sciences University of Iceland. The oxygen isotope measurements were performed on the Finnigan MAT 251 Mass-spectrometer. The isotope data is expressed as: 18Osample = ((Rsample/Rstandard)-1)1000‰ where R is 18O/16O and the standard used is SMOW-Standard Mean Ocean Water (Craig, 1961). Oxygen is extracted from the water by equilibrating 5 ml of degassed water with a small amount of CO2 gas in a sealed tube for 3 h, in a shaking waterbath (Epstein and Mayeda, 1953). The measurements are subsequently corrected for the CO2 gas which also was used as a secondary reference standard. The accuracy of the measurements is 0.03‰.
