| The system consists of a wet box and a dry box. In the wet box, surface seawater is brought into equilibrium with air, which is measured for its CO2 content in the dry box. CO2 determination is peformed with a Li-cor Infra Red (IR) analyser.||||

| Preliminary, uncorrected measurement data. Reporting of a preliminary pCO2 (based on xco2, equtemp in licorpres) was implemented in May 2015, for reporting to DSHIP and on to AWI. Please note that these data are NOT the final product of this instrument. After-cruise processing of the data improves the values significantly compared to the preliminary value.||||

After the cruise the uncorrected DShip data set can be extracted from https://dms.awi.de.
The data need processing for correcting the raw data to useful and high-quality pCO2 data. Final data are stored in SOCAT (https://www.socat.info), where further quality control is done. Also available in https://www.pangaea.de/ (for authorized users only). | ||
