Abstract
  • To investigate CO₂ chemistry in ocean water with greater time-space resolutions, we systems, which have state-of-the-art precision but an order of magnitude or better analysis, for carbon dioxide partial pressures (Pco₂) and total carbon dioxide Pco₂ system was based on equilibration of a CO₂-free carrier gas stream with seawater sample stream using a commercially available membrane contactor unit applications followed by nondispersive infrared (NDIR) absorbance detection of the The Tco₂ system was based on injection of a small-volume seawater sample loop liquid carrier stream to convert all carbonate and bicarbonate ions to aqueous was then passed through a custom-made small-volume membrane contactor unit determined by equilibration of a CO₂-free carrier gas followed by NDIR detection. experiment in the Ross Sea polynya, Antarctica, are presented. The Pco₂ system time of about 3 s and precision of better than 1 μatm. The Tco₂ system had a per 36 s, and reproducibility was determined to be better than 0.2% for a period of hours.
