英文摘要
Temporal variations of atmospheric CH_4 concentration over the last 130 kyrs were reconstructed from deep ice cores drilled at Dome Fuji, Antarctica and NGRIP and NEEM, Greenland. By analyzing the reconstructed differences of CH_4 concentration between north and south polar regions using an atmospheric model, spatiotemporal variations of CH_4 emissions from natural sources were closely examined. The values ofδ^<13>C andδD of atmospheric CH_4 were also reconstructed using the Dome Fuji deep ice core. Based on their temporal variations, causes of glacial/interglacial variations in atmospheric CH_4 were discussed especially in terms of changes in CH_4 emissions from natural sources.
