Surface underway measurements of partial pressure of carbon dioxide (pCO2), sea surface salinity, temperature and other parameters during the ship of opportunity (SOOP) M/S New Century 2 cruises in the Pacific Ocean, Atlantic Ocean and Caribbean Sea in 2023 (NCEI Accession 0287492)

This dataset includes surface underway, chemical, meteorological and physical data collected from M/S New Century 2 in the Pacific Ocean, Caribbean Sea, Atlantic Ocean from 2023-01-08 to 2023-12-31. These data include absolute humidity, air temperature, air-sea difference - partial pressure of carbon dioxide, barometric pressure, partial pressure of carbon dioxide - atmosphere, partial pressure of carbon dioxide - water, relative humidity, sea surface salinity, sea surface temperature and wind direction and speed. The instruments used to collect these data include barometric pressure sensor, carbon dioxide (CO2) gas analyzer, tandem (bubble+mixer) type equilibrator for autonomous CO2 measurement and thermosalinographs.
