Parameter detail
Other Descriptions for Sampling and Analyses The measurements for air and surface sea water are carried out. The height of intake for air sample is 31 meters above sea surface. The depth of the intake for sea water sample is 11 meters below sea surface. The sea water is introduced into the equilibrator. Both ambient air and equilibrated air are dried using an electronic dehumidifier, perma-pure dryer and chemical desiccant (Mg(ClO4)2) at dew-point lowerthan 2°C, -40°C, -70°C respectivery.
Continuous NDIR analyzer
Scientific Aim To deduce CO2 seasonal variations and sources or sinks in the North Pacific.
