 The measurement for air and surface sea water are carried out. The height of intake is about 10m above sea surface and about 5m below sea surface. The water is introduced into the equilibrator. Both introduced ambient air and equilibrated air are dried by the electronic coolong unit, perma pure dryer and chemical dryer (Mg(ClO4)2).
Continuous NDIR analizer
To reveal the interaction between ambient air and seawater in the western North Pacific Ocean.
