Surface underway measurements of partial pressure of CO2 (pCO2), sea surface temperature, sea surface salinity and barometric pressure collected during the M/V Atlantic Sail Ships of Opportunity (SOOP) cruises in the North Atlantic Ocean in 2021 (NCEI Accession 0246952)

This dataset includes surface underway, chemical, meteorological and physical data collected during the M/V Atlantic Sail Ships of Opportunity (SOOP) cruises in the North Atlantic Ocean from 2021-03-03 to 2021-11-09. These data include partial pressure (or fugacity) of carbon dioxide - atmosphere, partial pressure (or fugacity) of carbon dioxide - water, sea surface salinity, sea surface temperature and barometric pressure. The instruments used to collect these data include Carbon dioxide (CO2) gas analyzer. GEOMAR operates surface ocean pCO2 measurements in the sub-polar North Atlantic since 2002 on different ships of opportunities (SOOP lines). The measurements are now embedded in the frame work of the European infrastructure "Integrated Carbon Observation System (ICOS)"
