We surveyed New Zealand (NZ) and Canadian Pacific Coast (CPC) and designated OAE2 horizon with carbon isotope and microbiostratigraphy. In NZ, red mudstone bed indicate oxigenation of bottom environment during OAE2 interval. In CPC, anoxia below the OAE2 horizon and gradual recovery of oxygen environment toward OAE2 were observed. Oscillation of bottom water redox condition with inverted phase in middle-high latitude Pacific against proto-Atlantic regions are documented showing complicated nature of OAE2 as a global event. We also obtained an evidence of incleasing seasonal aridity toward OAE2 time in CPC. Evidence of such climatic response on land across OAE2 was rarely presented through this interval and will be further studied.","subitem_description_type":"Abstract"}]},"item_9_description_22":{"attribute_name":"内容記述","attribute_value_mlt":[{"subitem_description":"研究課題/領域番号:24403012, 研究期間(年度):2012-04-01 – 2015-03-31","subitem_description_type":"Other"},{"subitem_description":"出典：研究課題「白亜紀OAE2における海底溶存酸素のグローバル・シーソー振動の解明」課題番号24403012\n（KAKEN：科学研究費助成事業データベース（国立情報学研究所））\n（https://kaken.nii.ac.jp/report/KAKENHI-PROJECT-24403012/24403012seika/）を加工して作成","subitem_description_type":"Other"}]},"item_9_description_5":{"attribute_name":"提供者所属","attribute_value_mlt":[{"subitem_description":"金沢大学理工学域自然システム学系","subitem_description_type":"Other"}]},"item_9_identifier_registration":{"attribute_name":"ID登録","attribute_value_mlt":[{"subitem_identifier_reg_text":"10.24517/00049414","subitem_identifier_reg_type":"JaLC"}]},"item_9_relation_28":{"attribute_name":"関連URI","attribute_value_mlt":[{"subitem_relation_name":[{"subitem_relation_name_text":"https://kaken.nii.ac.jp/search/?qm=50272943"}],"subitem_relation_type_id":{"subitem_relation_type_id_text":"https://kaken.nii.ac.jp/search/?qm=50272943","subitem_relation_type_select":"URI"}},{"subitem_relation_name":[{"subitem_relation_name_text":"https://kaken.nii.ac.jp/grant/KAKENHI-PROJECT-24403012/"}],"subitem_relation_type_id":{"subitem_relation_type_id_text":"https://kaken.nii.ac.jp/grant/KAKENHI-PROJECT-24403012/","subitem_relation_type_select":"URI"}},{"subitem_relation_name":[{"subitem_relation_name_text":"https://kaken.nii.ac.jp/report/KAKENHI-PROJECT-24403012/24403012seika/"}],"subitem_relation_type_id":{"subitem_relation_type_id_text":"https://kaken.nii.ac.jp/report/KAKENHI-PROJECT-24403012/24403012seika/","subitem_relation_type_select":"URI"}}]},"item_9_version_type_25":{"attribute_name":"著者版フラグ","attribute_value_mlt":[{"subitem_version_resource":"http://purl.org/coar/version/c_ab4af688f83e57aa","subitem_version_type":"AM"}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2017-12-21"}],"displaytype":"detail","filename":"SC-PR-HASEGAWA-T-keken 2015-6p.pdf","filesize":[{"value":"608.9 kB"}],"format":"application/pdf","licensetype":"license_11","mimetype":"application/pdf","url":{"label":"SC-PR-HASEGAWA-T-keken 2015-6p.pdf","url":"https://kanazawa-u.repo.nii.ac.jp/record/43067/files/SC-PR-HASEGAWA-T-keken 2015-6p.pdf"},"version_id":"7471817b-05e0-465a-9d1c-5366553dcbe5"}]},"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":"research report","resourceuri":"http://purl.org/coar/resource_type/c_18ws"}]},"item_title":"白亜紀OAE2における海底溶存酸素のグローバル・シーソー振動の解明","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"白亜紀OAE2における海底溶存酸素のグローバル・シーソー振動の解明"},{"subitem_title":"Global seesaw oscillation of botom water redox condition through Cretaceous OAE2","subitem_title_language":"en"}]},"item_type_id":"9","owner":"18","path":["2819"],"pubdate":{"attribute_name":"公開日","attribute_value":"2017-12-21"},"publish_date":"2017-12-21","publish_status":"0","recid":"43067","relation_version_is_last":true,"title":["白亜紀OAE2における海底溶存酸素のグローバル・シーソー振動の解明"],"weko_creator_id":"18","weko_shared_id":-1},"updated":"2023-07-27T10:45:14.751079+00:00"}
