Concentration of atmospheric and oceanic methane : 2012 The Northwest Pacific Transect
Listed in NASA Earthdata CMR
Atmospheric and oceanic methane in the marine boundary layer were monitored from July 14 to July 29 by the GC 7890A along the cruise track of R/V Araon from Incheon to Nome(Alaska) carrying out a series of expeditions in The Northwest Pacific.
Description
The air inlet to the instrument was located at 29 m asl and the sea water inlet was located at 7m depth. CH4 was measured every 40 minutes.
As atmospheric methane 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.
