Concentration of atmospheric and oceanic nitrous oxide : 2013 The Ross Sea

Atmospheric and oceanic nitrous oxide in the marine boundary layer was monitored from January 26 to February 28 by the GC 7890A along the cruise track of R/V Araon from Christchurch(New Zealand) to the McMurdo Station(Ross Island) carrying out a series of expeditions in The Ross Sea. The air inlet to the instrument was located at 29 m asl and the sea water inlet was located at 7m depth. N2O was measured every 40 minutes.
As atmospheric nitrous oxide is one of the major green house gases, it is important to understand the degree of influence of it. Although oceanic source doesn't contribute highly, it is required to monitor air-sea flux continuously because the area of the Ocean is large and the flux changes easily according to the chemical and biological conditions.
