The sedimentation rate of the lake sediments assumed by ^<210>Pb is about 3mm/y. 137Cs, a fallout product from atmospheric nuclear weapon tests, shows maximum activity at 9.5cm depth. Maximum fallout of ^<137>Cs to water and land occurred during 1963-1964,and the sedimentation rate assumed by ^<137>Cs is also about 3mm/y. The sedimentation rate of 3mm/y, however, could be untrue because surface sediments are disturbed and mixed by physical turbulence. Sr isotope ratios of the lake sediments radically change from 0.7185 to 0.7198,and Sr concentrations also radically change from 73ppm to 64ppm at near 10cm depth. Therefore, the following causes are expected : 1) Sr system has changed by artificially environment pollution since near 1960,and 2) surface sediments are disturbed and mixed by physical turbulence. In the case of 2), the profiles of ^<210>Pb and ^<137>Cs lead to mixing process except sedimentation process. The profiles of other nuclides such as ^<14>C and ^<90>Sr would help better understanding of the behavior of lake sediments. It is necessary to analyze another sediment cores of southern and northern Lake Biwa.","subitem_description_language":"en","subitem_description_type":"Abstract"}]},"item_9_description_5":{"attribute_name":"内容記述","attribute_value_mlt":[{"subitem_description":"第14回名古屋大学タンデトロン加速器質量分析計シンポジウム(平成13 (2001)年度)報告","subitem_description_language":"ja","subitem_description_type":"Other"}]},"item_9_identifier_registration":{"attribute_name":"ID登録","attribute_value_mlt":[{"subitem_identifier_reg_text":"10.18999/sumrua.13.71","subitem_identifier_reg_type":"JaLC"}]},"item_9_publisher_32":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"名古屋大学年代測定資料研究センター","subitem_publisher_language":"ja"}]},"item_9_relation_43":{"attribute_name":"関連情報","attribute_value_mlt":[{"subitem_relation_type":"isVersionOf","subitem_relation_type_id":{"subitem_relation_type_id_text":"http://ci.nii.ac.jp/naid/110000475713/","subitem_relation_type_select":"URI"}}]},"item_9_rights_12":{"attribute_name":"権利","attribute_value_mlt":[{"subitem_rights":"名古屋大学年代測定資料研究センター","subitem_rights_language":"ja"},{"subitem_rights":"本文データは学協会の許諾に基づきCiNiiから複製したものである","subitem_rights_language":"ja"}]},"item_9_select_15":{"attribute_name":"著者版フラグ","attribute_value_mlt":[{"subitem_select_item":"publisher"}]},"item_9_text_14":{"attribute_name":"フォーマット","attribute_value_mlt":[{"subitem_text_value":"application/pdf"}]},"item_access_right":{"attribute_name":"アクセス権","attribute_value_mlt":[{"subitem_access_right":"open access","subitem_access_right_uri":"http://purl.org/coar/access_right/c_abf2"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"南, 雅代","creatorNameLang":"ja"}],"nameIdentifiers":[{"nameIdentifier":"81272","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Minami, Masayo","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"81273","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"小田, 寛貴","creatorNameLang":"ja"}],"nameIdentifiers":[{"nameIdentifier":"81274","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Oda, Hirotaka","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"81275","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"小島, 貞男","creatorNameLang":"ja"}],"nameIdentifiers":[{"nameIdentifier":"81276","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Kojima, Sadao","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"81277","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"横田, 喜一郎","creatorNameLang":"ja"}],"nameIdentifiers":[{"nameIdentifier":"81278","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Yokota, Kiichiro","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"81279","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"中村, 俊夫","creatorNameLang":"ja"}],"nameIdentifiers":[{"nameIdentifier":"81280","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Nakamura, Toshio","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"81281","nameIdentifierScheme":"WEKO"}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2018-02-20"}],"displaytype":"detail","filename":"KJ00000187437.pdf","filesize":[{"value":"581.8 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"KJ00000187437.pdf","objectType":"fulltext","url":"https://nagoya.repo.nii.ac.jp/record/11669/files/KJ00000187437.pdf"},"version_id":"738e4968-cd9a-481b-a118-2c0ee1ae208d"}]},"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":"departmental bulletin paper","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"琵琶湖南湖の湖底堆積物のSr同位体比","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"琵琶湖南湖の湖底堆積物のSr同位体比","subitem_title_language":"ja"}]},"item_type_id":"9","owner":"17","path":["1238"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2010-06-01"},"publish_date":"2010-06-01","publish_status":"0","recid":"11669","relation_version_is_last":true,"title":["琵琶湖南湖の湖底堆積物のSr同位体比"],"weko_creator_id":"17","weko_shared_id":-1},"updated":"2023-11-13T06:06:35.521223+00:00"}
