The sedimentary core samples (25-30cm in length) were collected from two sites (SC-8 : 5°N, 156°E, 3604m deep ; SC-9 : 0°, 158°E, 2226m deep) in the Equatorial Central Pacific by a box core sampler. The core samples were sliced into thin layer of the sediment with 1cm thick, from which foraminiferal tests were separated by using of the sieve with 60 mesh. The tests were analyzed for amino acid composition, D- and L- amino acid ratio and ^<14>C/^<13>C ratio. Following results were obtained. 1) D/L ratio of aspartic acid and ^<14>C age tended to increase as increase in the depth from the top of the core samples, suggesting that D/L ratio of aspartic acid can be applied for the determination of age of the sediment samples. 2) Thus, racemization rate constant (k_<ASP>) of aspartic acid was calculated for these two core samples. 0.66x10^<-5> yr^<-1> and 1.01x10^<-5> yr^<-1> were obtained for k_<ASP> of SC-8 and SC-9 respectively. 3) Such difference in k_<ASP> between these two core samples are discussed from the points of the ambient water temperature and bioturbation.","subitem_description_language":"en","subitem_description_type":"Abstract"}]},"item_9_identifier_registration":{"attribute_name":"ID登録","attribute_value_mlt":[{"subitem_identifier_reg_text":"10.18999/sumrua.2.52","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 天然放射性元素測定小委員会","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/110000475762/","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 天然放射性元素測定小委員会","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":"原田, 尚美","creatorNameLang":"ja"}],"nameIdentifiers":[{"nameIdentifier":"79411","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Harada, Naomi","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"79412","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"半田, 暢彦","creatorNameLang":"ja"}],"nameIdentifiers":[{"nameIdentifier":"79413","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Handa, Nobuhiko","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"79414","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":"KJ00000187493.pdf","filesize":[{"value":"374.2 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"KJ00000187493.pdf","objectType":"fulltext","url":"https://nagoya.repo.nii.ac.jp/record/11310/files/KJ00000187493.pdf"},"version_id":"21c45c06-a1ae-488f-b1d5-feb53f898fdb"}]},"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":"浮遊性有孔虫殻のアミノ酸のラセミ化反応による海底堆積物の年代測定について","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"浮遊性有孔虫殻のアミノ酸のラセミ化反応による海底堆積物の年代測定について","subitem_title_language":"ja"}]},"item_type_id":"9","owner":"17","path":["1220"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2010-04-23"},"publish_date":"2010-04-23","publish_status":"0","recid":"11310","relation_version_is_last":true,"title":["浮遊性有孔虫殻のアミノ酸のラセミ化反応による海底堆積物の年代測定について"],"weko_creator_id":"17","weko_shared_id":-1},"updated":"2023-11-16T00:39:27.278185+00:00"}
