The aim of this study is to clarify the spatial distribution of chemical components in fresh snow, as well as the relationship between weather conditions and chemical characteristics of fresh snow in the Japanese Alps region. We conducted a snow pit study immediately after a snowfall on the route inland from Itoigawa city (N1) and Joetsu city (N2). We collected only fresh snow samples during the 2011/2012 winter season. The samples were melted and pH, electric conductivity, and major ions (Na+, K+, Mg2+, Ca2+, Cl-, NO3-, and SO42-) were analyzed in a clean room. The pH of all samples was below 5.62. Na+ concentration correlates well with Cl- concentration. These ions are considered to be sea-salt components. These ions indicate the absence of chlorine loss. On the other hand, SO42- concentrations included non-sea-salt components. Na+ and SO42- concentrations decreased rapidly inland from the coastal area. The Na+ concentration of the N2 route was higher than that of the N1 route. It is considered that geomorphological features such as valley width and altitude differences influenced the transportation of chemical components. The chemical characteristics of the fresh snow layer changed with differences in weather conditions. Concentrations of sea-salt components were high in fresh snow when the vicinity of Japan was under the strong winter monsoon pattern. On the other hand, concentrations of sea-salt components were very low with snowfalls of plain snow. As a result of extracting the characteristic layer of Na+ concentration, changes in the vertical profiles of Na+ concentration became similar from the coast to the inland study sites. At the inland study sites, most SO42- was of non-sea salt origin. We compared the depositions of Na+ and SO42- in the fresh snow layer. Whereas there were large depositions of Na+ at the sampling sites near the sea, depositions of SO42- increased inland. This is because non-sea salt components were carried inland more than sea salt components. At the inland sites, there was a layer of high NO3-/nssSO42- component in the fresh snow. It is thought that the generation of NO3- by human activities near the site had an influence.","subitem_description_type":"Abstract"}]},"item_6_description_30":{"attribute_name":"資源タイプ（コンテンツの種類）","attribute_value_mlt":[{"subitem_description":"Article","subitem_description_type":"Other"}]},"item_6_description_5":{"attribute_name":"引用","attribute_value_mlt":[{"subitem_description":"地学雑誌. 122(4):651-665 (2013)","subitem_description_type":"Other"}]},"item_6_link_3":{"attribute_name":"信州大学研究者総覧へのリンク","attribute_value_mlt":[{"subitem_link_text":"鈴木, 啓助","subitem_link_url":"http://soar-rd.shinshu-u.ac.jp/profile/ja.upTmOUkh.html"}]},"item_6_publisher_4":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"東京地学協会"}]},"item_6_relation_48":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_name":[{"subitem_relation_name_text":"10.5026/jgeography.122.651"}],"subitem_relation_type_id":{"subitem_relation_type_id_text":"https://doi.org/10.5026/jgeography.122.651","subitem_relation_type_select":"DOI"}}]},"item_6_source_id_35":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"0022-135X","subitem_source_identifier_type":"ISSN"}]},"item_6_source_id_40":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AN00322536","subitem_source_identifier_type":"NCID"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"倉元,  隆之"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"鈴木,  大地"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"佐々木,  明彦"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"鈴木,  啓助"}],"nameIdentifiers":[{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2015-09-28"}],"displaytype":"detail","filename":"Chigaku_Zasshi_122_4_651.pdf","filesize":[{"value":"3.1 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"Chigaku_Zasshi_122_4_651.pdf","url":"https://soar-ir.repo.nii.ac.jp/record/11771/files/Chigaku_Zasshi_122_4_651.pdf"},"version_id":"58fc97aa-5aa0-47fd-9840-72dbe40b8de8"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"新雪","subitem_subject_scheme":"Other"},{"subitem_subject":"fresh snow","subitem_subject_scheme":"Other"},{"subitem_subject":"雪氷化学","subitem_subject_scheme":"Other"},{"subitem_subject":"snow chemistry","subitem_subject_scheme":"Other"},{"subitem_subject":"化学成分","subitem_subject_scheme":"Other"},{"subitem_subject":"chemical components","subitem_subject_scheme":"Other"},{"subitem_subject":"空間分布","subitem_subject_scheme":"Other"},{"subitem_subject":"spatial distribution","subitem_subject_scheme":"Other"},{"subitem_subject":"中部山岳地域","subitem_subject_scheme":"Other"},{"subitem_subject":"the Japanese Alps region","subitem_subject_scheme":"Other"}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"jpn"}]},"item_resource_type":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"resourcetype":"journal article","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"中部山岳地域の降雪に含まれる化学成分濃度の空間分布","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"中部山岳地域の降雪に含まれる化学成分濃度の空間分布","subitem_title_language":"ja"}]},"item_type_id":"6","owner":"1","path":["1170"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2013-10-04"},"publish_date":"2013-10-04","publish_status":"0","recid":"11771","relation_version_is_last":true,"title":["中部山岳地域の降雪に含まれる化学成分濃度の空間分布"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2022-12-14T04:11:34.363880+00:00"}
