Outline of Final Research Achievements |
Triple oxygen isotopic analysis is useful tool to elucidate formation pathways for atmospheric sulfate and nitrate. In this study, we develop new system measuring triple oxygen isotopic compositions of several sulfate/nitrate samples including cryospheric samples. By using this method, we investigated the triple oxygen isotopic compositions of sulfate and nitrate preserved in ice core drilled at SE-Dome, Greenland.
