Studies of planktonic Foraminifera indicate that there have been two, possibly three, cycles of warming in which the limits of the tropical zone have extended well north of the 40 degree parallel within the Upper Cretaceous-Cenozoic interval. A prominent cycle of warming occurred in the Upper Cretaceous, a second in the later Paleocene and lower Eocene, and a third minor one in the later Eocene. These cycles of warming and cooling are in contradiction to other types of data. The disparity is possibly due to the lack of sampling density for other types of fossil evidence or the greater temperature sensitivity of planktonic Foraminifera.","subitem_description_type":"Abstract"}]},"item_4_description_41":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"subitem_description":"紀要類(bulletin)","subitem_description_type":"Other"}]},"item_4_description_66":{"attribute_name":"フォーマット","attribute_value_mlt":[{"subitem_description":"562187 bytes","subitem_description_type":"Other"}]},"item_4_publisher_34":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"Tohoku University"}]},"item_4_radio_69":{"attribute_name":"公開範囲","attribute_value_mlt":[{"subitem_radio_item":"学外"}]},"item_4_source_id_7":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"0082464X","subitem_source_identifier_type":"ISSN"}]},"item_4_source_id_9":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AA0083635X","subitem_source_identifier_type":"NCID"}]},"item_4_version_type_16":{"attribute_name":"著者版フラグ","attribute_value_mlt":[{"subitem_version_resource":"http://purl.org/coar/version/c_970fb48d4fbd8a85","subitem_version_type":"VoR"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"Bandy, Orville L."}],"nameIdentifiers":[{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2017-02-03"}],"displaytype":"detail","filename":"KJ00004163729.pdf","filesize":[{"value":"562.2 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"KJ00004163729.pdf","url":"https://tohoku.repo.nii.ac.jp/record/10731/files/KJ00004163729.pdf"},"version_id":"90a1085b-3ce8-449f-9802-db3ac14484d2"}]},"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":"Planktonic Foraminiferal Criteria for Paleoclimatic Zonation","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Planktonic Foraminiferal Criteria for Paleoclimatic Zonation"}]},"item_type_id":"4","owner":"3","path":["151"],"pubdate":{"attribute_name":"公開日","attribute_value":"2008-05-02"},"publish_date":"2008-05-02","publish_status":"0","recid":"10731","relation_version_is_last":true,"title":["Planktonic Foraminiferal Criteria for Paleoclimatic Zonation"],"weko_creator_id":"3","weko_shared_id":3},"updated":"2023-07-27T19:08:58.769952+00:00"}
