Concentrations of atmospheric and oceanic molecular H2: The West Equatorial Pacific transect in 2010
Listed in NASA Earthdata CMR
Atmospheric and oceanic molecular hydrogen in the marine boundary layer was monitored from October 10 to 29 by the RGA3 along the cruise track of R/V Araon from Incheon to Christchurch carrying out a series of expeditions in The West Equatorial Pacific.
Description
The air inlet to the instrument was located at 29 m the foremast and seawater inlet at 7m depth. Both air and water samples were measured once per 45 minutes.
Atmospheric molecular hydrogen goes up to the stratosphere easyly, and oxidized to H2O. Therefore it plays a key role in the stratospheric ozone chemistry and affects the global climate. Also its measurements in the ocean is very important because the production and removal mechanism in the ocean that is one of the sources of H2 has not been understood yet.
