Partial pressure (or fugacity) of carbon dioxide, temperature, salinity and other variables collected from surface underway observations using carbon dioxide gas analyzer, shower head equilibrator and other instruments from R/V Meteor research cruise along the WOCE Section AR12/AR24 (EXPOCODE 06MT19970515) in the North Atlantic Ocean from 1997-05-15 to 1997-06-08 (NCEI Accession 0162256)
- GEOMAR Helmholtz Centre for Ocean Research Kiel, Kiel, GermanyPACKAGE DESCRIPTION: This dataset includes Surface underway, chemical, meteorological and physical data collected from R/V Meteor research cruise along the WOCE SectionAR12/AR24 (EXPOCODE 06MT19970515) in the North Atlantic Ocean from 1997-05-15 to 1997-06-08. These data include measurements of mole fraction of CO2 in the equilibrator headspace (dry) at equilibrator temperature, mole fraction of CO2 measured in dry outside air, barometric pressure in the equilibrator headspace, water temperature in equilibrator, sea surface temperature, sea surface salinity and fugacity of CO2 in sea water at SST and 100% humidity. The instruments used to collect these data include carbon dioxide (CO2) gas analyzer and shower head chamber equilibrator for autonomous carbon dioxide (CO2) measurement. These data were collected by Arne Körtzinger of Institute of Marine Research, Germany.
