Average multiple-year background concentration levels are calculated for each ion at each site from laboratory measurements of continuous core samples representing from 4 to 10 years of snow accumulation (32 to 80 individual measurements) from various time intervals. The HCOO^- concentration level increases from 6 ng/g in the northern most cold site to 36 ng/g in the southern most warm site; CH_3SO_3^- increases from 0.9 ng/g to 2.8 ng/g; NO_3^- decreases from 83 ng/g to 37 ng/g; excess SO_4^<2-> decreases from 43 ng/g to 19 ng/g, all with variability. The distribution of the NH_4^+ ion shows a nearly constant level at about 6 ng/g for all sites except Dye-2 where it reaches 10 ng/g. The deposition patterns for HCOO^- and NH_4^+ on the ice sheet suggest that major contributions arrive from sources originating from the southwest of Greenland.","subitem_description_type":"Other"}]},"item_1_identifier_registration":{"attribute_name":"ID登録","attribute_value_mlt":[{"subitem_identifier_reg_text":"10.15094/00003855","subitem_identifier_reg_type":"JaLC"}]},"item_1_publisher_22":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"National Institute of Polar Research"}]},"item_1_source_id_13":{"attribute_name":"雑誌書誌ID","attribute_value_mlt":[{"subitem_source_identifier":"AA10756213","subitem_source_identifier_type":"NCID"}]},"item_1_text_10":{"attribute_name":"著者所属(英)","attribute_value_mlt":[{"subitem_text_language":"en","subitem_text_value":"Solar-Terrestrial Environment Laboratory, Nagoya University"},{"subitem_text_language":"en","subitem_text_value":"Department of Geology, State University of New York at Buffalo"}]},"item_1_text_3":{"attribute_name":"記事種別(英)","attribute_value_mlt":[{"subitem_text_language":"en","subitem_text_value":"ABSTRACT"}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"1994-11-01"}],"displaytype":"detail","filename":"KJ00000767963.pdf","filesize":[{"value":"69.1 kB"}],"format":"application/pdf","licensetype":"license_6","mimetype":"application/pdf","url":{"label":"KJ00000767963","url":"https://nipr.repo.nii.ac.jp/record/3855/files/KJ00000767963.pdf"},"version_id":"b8ddc0fb-42fb-442e-912f-ee44c1674885"}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"eng"}]},"item_resource_type":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"resourcetype":"departmental bulletin paper","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"BACKGROUND LEVELS OF HCOO^-, CH_3SO_3^-, NO_3^-, SO_4^<2-> AND NH_4^+ IN ICE CORES FROM INLAND GREENLAND","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"BACKGROUND LEVELS OF HCOO^-, CH_3SO_3^-, NO_3^-, SO_4^<2-> AND NH_4^+ IN ICE CORES FROM INLAND GREENLAND"}]},"item_type_id":"1","owner":"4","path":["532"],"pubdate":{"attribute_name":"公開日","attribute_value":"1994-11-01"},"publish_date":"1994-11-01","publish_status":"0","recid":"3855","relation_version_is_last":true,"title":["BACKGROUND LEVELS OF HCOO^-, CH_3SO_3^-, NO_3^-, SO_4^<2-> AND NH_4^+ IN ICE CORES FROM INLAND GREENLAND"],"weko_creator_id":"4","weko_shared_id":4},"updated":"2023-07-25T12:27:42.719523+00:00"}
