Accurate to ± 0.01°C.; How was pressure inside the equilibrator measured: Setra 239 differential pressure transducer, accurate to ± 0.15 hPa. The equilibrator was passively vented to a secondary equilibrator, and the Licor sample output was vented to the laboratory when CO2 measurements were made, thus equilibrator headspace pressure was assumed to be laboratory pressure.; Drying method for gas: From Pierrot et al.: Sample air is dried in a condenser that is cooled to 4-5 degrees Celsius by a Peltier thermoelectric device. This partially dried air flushes a chamber that is vented and remains at ambient pressure. The dried air inside the chamber is used as the counter flow in the Nafion® tubing. A vacuum pump pulls the dried air from the chamber first through a fixed restrictor and then through the Nafion® tubes, thus creating an absolute pressure and corresponding partial pressure gradient for water vapor across the membrane. When atmospheric air is measured, some of the partially dried air (80-100 mL/min) is pushed through a Nafion® tube, the analyzer and out a vent instead of flushing the chamber. The headspace gas, when being measured, is circulated in a closed loop through the analyzer at a rate similar to that of the atmospheric air (80-100 mL/min). It is dried first in the condenser, then in a Nafion® tube prior to entering the analyzer and being returned to the equilibrator. Typically, the water mole fraction (xH2O) in the dried gas is about 2 parts per thousand (ppt), which corresponds to a dew point temperature of about -20 degrees C. The liquid water condensed out of the sample air streams is removed by peristaltic pumps into the vent equilibrator at intervals determined by the user.; SEA CO2 gas detector manufacturer: Licor, Inc; SEA CO2 gas detector model: Licor 7000, IRG4-0221; SEA CO2 gas detector resolution: 0.2 µatm; SEA CO2 gas detector uncertainty: 0.3 µatm for equilibrator measurements, 0.2 µatm for atmospheric measurements; Standardization technique: Autocalibration with Zero (Soda lime) and 466 ppm standard; Standardization frequency: once per day; Standard gas manufacturer: LOCEAN; Standard gas concentration: compressed air (diving facility) 200Bar in 0.5L AL-tank gas referenced with two standards from LOCEAN: 452.03 ppm and 352.49 ppm Measured: 436.7 ppm (2019-10-02); Standard gas uncertainty: better than 1% of reading, zero drift 0.15 ppm/°C, span drift 0.03 %/°C; Researcher name: Toste Tanhua; Researcher institution: GEOMAR Helmholtz Centre for Ocean Research Kiel, Kiel, Germany Parameter or Variable: Sea Surface Temperature; Abbreviation: SST_C; Unit: Degrees Celsius; Observation type: Surface Underway; Sampling instrument: In-situ observation; Analyzing instrument: SeaSun customized CTD48 #1603; Replicate information: Temperature last calibrated on 2019-09-05 by Sea and Sun Technology, Arndtstrasse 9, D-24610 Trappenkamp; Uncertainty: Resolution ± 0.005 °C; Uncertainty (Accuracy/Precision) ± 0.002 °C; Researcher name: Toste Tanhua; Researcher institution: GEOMAR Helmholtz Centre for Ocean Research Kiel, Kiel, Germany Parameter or Variable: Sea Surface Salinity; Abbreviation: SAL_PSU; Unit: PSU; Observation type: Surface Underway; Analyzing instrument: SeaSun customized CTD48 #1603; Replicate information: Conductivity last calibrated on 2019-09-06 by Sea and Sun Technology, Arndtstrasse 9, D-24610 Trappenkamp; Uncertainty: Resolution ± 0.010 mS/cm; Uncertainty (Accuracy/Precision) ± 0.002 mS/cm; Researcher name: Toste Tanhua; Researcher institution: GEOMAR Helmholtz Centre for Ocean Research Kiel, Kiel, Germany asNeeded Metadata are developed, maintained and distributed by NCEI.
