Oxygen and carbon isotopes from the samples obtained from there were analyzed.\nA carbonate concretion with 2 m in the major axis was found and identified as a cold methane seep carbonate based on internal structure and carbon isotope signatures. As it was formed just on the sea bottom, the oxygen isotope values were used for paleothermometry of bottom water at depsitional depth (~200 m). Surprizing low paleotemperature as low as 8 ℃ indicates domination of cool water mass that is complarable with deep water over upper bathyal depth of middle latitude North Eastern Pacific. This paleothermometry is important for paleoceanographic reconstruction of North Eastern Pacific during late Campanian.","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:15H05213, 研究期間(年度):2015-04-01 - 2018-03-31","subitem_description_type":"Other"},{"subitem_description":"出典：研究課題「温室地球と氷室地球の分岐点: カナダ太平洋岸白亜系の水温変動記録から探る」課題番号15H05213\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-15H05213/15H05213seika/)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":"金沢大学理工研究域地球社会基盤学系","subitem_description_type":"Other"}]},"item_9_identifier_registration":{"attribute_name":"ID登録","attribute_value_mlt":[{"subitem_identifier_reg_text":"10.24517/00051932","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-15H05213/"}],"subitem_relation_type_id":{"subitem_relation_type_id_text":"https://kaken.nii.ac.jp/grant/KAKENHI-PROJECT-15H05213/","subitem_relation_type_select":"URI"}},{"subitem_relation_name":[{"subitem_relation_name_text":"https://kaken.nii.ac.jp/report/KAKENHI-PROJECT-15H05213/15H05213seika/"}],"subitem_relation_type_id":{"subitem_relation_type_id_text":"https://kaken.nii.ac.jp/report/KAKENHI-PROJECT-15H05213/15H05213seika/","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":"2019-04-22"}],"displaytype":"detail","filename":"SC-PR-HASEGAWA-T-kaken 2018-6p.pdf","filesize":[{"value":"755.7 kB"}],"format":"application/pdf","licensetype":"license_11","mimetype":"application/pdf","url":{"label":"SC-PR-HASEGAWA-T-kaken 2018-6p.pdf","url":"https://kanazawa-u.repo.nii.ac.jp/record/45595/files/SC-PR-HASEGAWA-T-kaken 2018-6p.pdf"},"version_id":"9c10b61e-fbe0-4af9-842f-a7a894303b29"}]},"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":"温室地球と氷室地球の分岐点: カナダ太平洋岸白亜系の水温変動記録から探る","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"温室地球と氷室地球の分岐点: カナダ太平洋岸白亜系の水温変動記録から探る"},{"subitem_title":"Turning point between green house and ice house earths: investigation of paleothermometry from Cretaceous at Canadian Pacific Coast","subitem_title_language":"en"}]},"item_type_id":"9","owner":"18","path":["2816"],"pubdate":{"attribute_name":"公開日","attribute_value":"2019-04-22"},"publish_date":"2019-04-22","publish_status":"0","recid":"45595","relation_version_is_last":true,"title":["温室地球と氷室地球の分岐点: カナダ太平洋岸白亜系の水温変動記録から探る"],"weko_creator_id":"18","weko_shared_id":-1},"updated":"2023-07-27T12:58:26.882737+00:00"}
