  • Parameter or Variable: Sea Surface Temperature; Abbreviation: SEA_SURFACE_TEMPERATURE_C; Unit: Deg_C; Observation type: Surface underway; Sampling instrument: Ship's Underway system; Analyzing instrument: SBE58; Detailed sampling and analyzing information: The SST temperature measurements are from the Seabird 21 TSG, which is immersed in the instrument chest of the ship in the bow thruster space. SST data were interpolated from the underway fCO2 dataset to the timestamp of the pH sensor; Uncertainty: Factory calibraiton better than 0.01 C; not verified on cruise; Researcher name: Rik Wanninkhof; Researcher institution: NOAA/AOML.
  • Parameter or Variable: Sea Surface Salinity; Abbreviation: SALINITY_PSS_78; Unit: PSS78; Observation type: Surface underway; Sampling instrument: Ship's Underway system; Analyzing instrument: SBE45; Detailed sampling and analyzing information: The salinity measurements are from the Seabird 45 Micro TSG in the underway fCO2 system.
