Ratios of Cl/Na^+ in snow were higher than that in sea water, whereas SO_4^<2->/Na^+ ratios were lower in snow samples. The degree of SO_4^2 depletion relative to the sea water composition increased with increase in Na^+ concentration. From comparison with a simple chemical mass balance model using the SO_4^<2->/Na^+ ratios in the samples, depletion of SO_4^<2-> in snow is considered to be largely attributed to the fractionation of sulfate by forming Mirabilite (Na_2SO_4・10H_2O) during sea ice growth. The Br/Na^+ ratios of the snow predicted from the fractionation model differ significantly from the observed values : positive deviations were found in dark early July and negative deviations were seen in September. This could have resulted from Br_2 release from the snow after local sunrise. In winter aerosols collected at Syowa Station, depletion of SO_4^<2-> was also found. Based on statistics of meteorological data at Syowa Station, as appropriate conditions of meteorological and salt concentrations in drifting snow particle were fulfilled, the depletion of SO_4^2 in aerosol particles in winter can be explained by sublimation of salted drifting snow particles from the sea ice area.","subitem_description_type":"Other"}]},"item_1_identifier_registration":{"attribute_name":"ID登録","attribute_value_mlt":[{"subitem_identifier_reg_text":"10.15094/00002927","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":"AA1129795X","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":"STEL, Nagoya University"},{"subitem_text_language":"en","subitem_text_value":"STEL, Nagoya University:National Institute of Polar Research"},{"subitem_text_language":"en","subitem_text_value":"STEL, Nagoya University"},{"subitem_text_language":"en","subitem_text_value":"RESTEC"},{"subitem_text_language":"en","subitem_text_value":"National Institute of Polar Research"},{"subitem_text_language":"en","subitem_text_value":"National Institute of Polar Research"},{"subitem_text_language":"en","subitem_text_value":"STEL, Nagoya University"},{"subitem_text_language":"en","subitem_text_value":"STEL, Nagoya University"}]},"item_1_text_3":{"attribute_name":"記事種別(英)","attribute_value_mlt":[{"subitem_text_language":"en","subitem_text_value":"Scientific Paper"}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2001-11-01"}],"displaytype":"detail","filename":"KJ00002364414.pdf","filesize":[{"value":"1.2 MB"}],"format":"application/pdf","licensetype":"license_6","mimetype":"application/pdf","url":{"label":"KJ00002364414","url":"https://nipr.repo.nii.ac.jp/record/2927/files/KJ00002364414.pdf"},"version_id":"040a979e-6938-4614-a6ce-b3a79c955c50"}]},"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":"Sulfate depletion in snow over sea ice near Syowa Station, Antarctica, in relation to the origin of sulfate depleted sea salt aerosol particles in winter","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Sulfate depletion in snow over sea ice near Syowa Station, Antarctica, in relation to the origin of sulfate depleted sea salt aerosol particles in winter"}]},"item_type_id":"1","owner":"4","path":["429"],"pubdate":{"attribute_name":"公開日","attribute_value":"2001-11-01"},"publish_date":"2001-11-01","publish_status":"0","recid":"2927","relation_version_is_last":true,"title":["Sulfate depletion in snow over sea ice near Syowa Station, Antarctica, in relation to the origin of sulfate depleted sea salt aerosol particles in winter"],"weko_creator_id":"4","weko_shared_id":4},"updated":"2023-07-25T12:40:35.657842+00:00"}
