Outline of Final Research Achievements

The Southeastern Greenland Dome (SE-Dome) has both a high elevation and a high accumulation rate (1.01 m w.e. yr-1), which are suitable properties for reconstructing past environmental changes with a high time resolution. For this study, we measured the major ion fluxes in a 90-m ice core drilled from the SE-Dome region in 2015, and present the records of annual ion fluxes from 1957 to 2014. From 1970 to 2010, the trend of non-sea-salt (nss) SO42- flux decreases, whereas that for NH4+ increases, tracking well with the anthropogenic SOx and NH3 emissions mainly from North America. The result suggests that these fluxes reflect histories of the anthropogenic SOx and NH3 emissions. In contrast, the decadal trend of NO3- flux differs from the decreasing trend of anthropogenic NOx emissions.

Academic Significance and Societal Importance of the Research Achievements

エアロゾルの寒冷化メカニズムを評価する一つの有力な取り組みとして、近年の人為起源水溶性エアロゾルの変遷を解読し、 過去から現在のエアロゾル変遷と気温変動の関係をふまえて将来予測をしていく方法がある。北極グリーンランド氷床コアは産業革命を起こした欧州や北米に近く、低温のためエアロゾルが良く保存されており、人為起源エアロゾルの変遷を評価するにあたり、最適の古環境媒体である。本研究は21世紀に入ってからの欧州や北米の硝酸エアロゾルの排出抑制よりも実際に大気中に存在している硝酸エアロゾルは高い値を維持していることを明らかにした。
