Surface underway measurements of partial pressure of carbon dioxide (pCO2) in the Atlantic Ocean during the M/N Colibri Ships of Opportunity (SOOP) lines in 2018 (NCEI Accession 0184703)

INVESTIGATORS:
Nathalie Lefèvre - Sorbonne University (SU)
Denis Diverrès - French National Research Institute for Sustainable Development (IRD)

PACKAGE DESCRIPTION: This dataset includes surface underway, chemical, meteorological and physical data collected from MN Colibri in the English Channel and North Atlantic Ocean from 2018-04-30 to 2018-05-12. These data include barometric pressure, partial pressure of carbon dioxide - atmosphere, partial pressure of carbon dioxide - water, sea surface salinity and temperature. The instruments used to collect these data include Carbon dioxide (CO2) gas analyzer.

ADDITIONAL INFORMATION:
The CO2 analyser was designed and built by Craig Neil. It is fully automated. On MN Colibri, it is located in the ship's bow thruster space. A Seabird SBE21 thermosalinograph is installed on the same sea water inlet piping. An air inlet is placed on top of the bridge. It allows atmospheric CO2 measurements in conjunction with surface water CO2 observations.
