Concentrations of atmospheric and oceanic molecular H2 : 2009/2010 The Southern Ocean

Atmospheric and oceanic molecular hydrogen in the marine boundary layer was monitored from November 26, 2010, to January 22, 2011, using a RGA gas chromatograph along the cruise track of R/V Polarstern from Punta Arenas, Chile, to Wellington, New Zealand, carrying out the expedition, ANTXXVI/2, in the Southern Ocean. The air inlet to the instrument was located at ~30 m asl and the sea water inlet was located 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.
