This dataset includes Surface underway data collected from R/V G.O. Sars in the North Atlantic Ocean, Norwegian Sea and North Sea from 2016-02-20 to 2016-11-30. These data include barometric pressure, partial pressure (or fugacity) of carbon dioxide - atmosphere, partial pressure (or fugacity) of carbon dioxide - water, sea surface salinity and sea surface temperature. The instruments used to collect these data include carbon dioxide (CO2) gas analyzer, shower head chamber equilibrator for autonomous carbon dioxide (CO2) measurement. These data were collected by Ingunn Skjelvan of Uni Research Climate and Geophysical Institute, University of Bergen as part of the SOOP_GO_Sars_20016 data set.
The major objectives of the measurements is to provide a high quality measurements of atmospheric and sea surface fCO2, sea surface salinity, temperature, and other parameters in the North Atlantic Ocean, Norwegian Sea and North Sea.

carbon dioxide (CO2) gas analyzer
carbon dioxide (CO2) gas analyzer
measures gaseous carbon dioxide
Carbon dioxide gas analyzer has often been referred to as LI-COR, because a lot of researchers choose to use products manufactured by LI-COR incorporation for their carbon dioxide measurement. The main component of a carbon dioxide analyzer is a nondispersive infrared (NDIR) spectroscopic sensors to detect CO2 in a gaseous environment by its characteristic absorption.
Carbon dioxide (CO2) gas analyzer works together with carbon dioxide (CO2) equilibrator (insttypes_id 184) to measure carbon dioxide in the water.
To measure water carbon dioxide, water needs to be continuously supplied to a showerhead inside an equilibrator. As the water flows through the equilibrator chamber, dissolved carbon dioxide exchanges quickly with air in the headspace. This air is then sampled by the carbon dioxide analyzer to determine the mole fraction of CO2 in water.
showerhead equilibrator
showerhead equilibrator
extracts dissolved CO2 from water
A carbon dioxide equilibrator is usually in the shape of a vertical tube, with a showerhead on the top, some headspace, a lot of beads to increase the surface exchange area between water and air, a water seal device at the bottom to allow water to overflow, but prevents air exchange between inside and outside.
Carbon dioxide (CO2) equilibrator works together with carbon dioxide (CO2) gas analyzer (insttypes_id 183) to measure carbon dioxide in the water.
To measure water carbon dioxide, water needs to be continuously supplied to a showerhead inside an equilibrator. As the water flows through the equilibrator chamber, dissolved carbon dioxide exchanges quickly with air in the headspace. This air is then sampled by the carbon dioxide analyzer to determine the mole fraction of CO2 in water.
