The results of stratigraphic analyses, and chemical and \u03b4^\u003c18\u003eO analyses from Vestfonna and Austfonna cores are presented here. The results from these sites show that most of the chemical constituents contained in the initial snow cover still remained in the ice cores, although re-distribution of them by melt water percolation had occurred. Anthropogenic increases in trace metals, sulfate and nitrate since about 1950 are detected. This suggests that ice-core chemistry records from Nordaustlandet, Svalbard, can be useful to reconstruct past atmospheric conditions. In addition to chemical records, \u03b4^\u003c18\u003eO records, that correlate well with the temperature records in Svalbard, can be used to reconstruct past temperature changes.", "subitem_description_type": "Abstract"}]}, "item_3_description_194": {"attribute_name": "\u30d5\u30a9\u30fc\u30de\u30c3\u30c8", "attribute_value_mlt": [{"subitem_description": "application/pdf", "subitem_description_type": "Other"}]}, "item_3_full_name_183": {"attribute_name": "\u8457\u8005\u5225\u540d", "attribute_value_mlt": [{"nameIdentifiers": [{"nameIdentifier": "36964", "nameIdentifierScheme": "WEKO"}], "names": [{"name": "\u4e80\u7530, \u8cb4\u96c4", "nameLang": "ja"}]}]}, "item_3_publisher_212": {"attribute_name": "\u51fa\u7248\u8005", "attribute_value_mlt": [{"subitem_publisher": "\u56fd\u7acb\u6975\u5730\u7814\u7a76\u6240"}]}, "item_3_rights_192": {"attribute_name": "\u6a29\u5229", "attribute_value_mlt": [{"subitem_rights": "NATIONAL INSTITUTE OF POLAR RESEARCH, Watanabe Okitsugu, Motoyama Hideaki, Igarashi Makoto, Kamiyama Kokichi, Matoba Sumito, Goto-Azuma Kumiko, Narita Hideki, Kameda Takao, Memoirs of National Institute of Polar Research.
