The assumed annual mean temperature -8℃ is in great disagreement with field evidence in East Hokkaido. The annual mean temperature ca. -2℃ appears to be more reasonable. Continuous permafrost environment seems to have never occurred in East and North Hokkaido, or northernmost Japan, but discontinuous permafrost under the forest tundra occurred even in the coldest period of the Last Glacial. Ice wedge polygons could be formed under the discontinuous permafrost environment with extraordinarily cold winter, which characterized the climate of northernmost Japan.","subitem_description_type":"Abstract"}]},"item_3_publisher_33":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"Department of Geography, Tokyo Metropolitan University"}]},"item_3_source_id_10":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AA00200173","subitem_source_identifier_type":"NCID"}]},"item_3_source_id_8":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"03868710","subitem_source_identifier_type":"ISSN"}]},"item_3_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":"Hirakawa, Kazuomi"}],"nameIdentifiers":[{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2016-08-04"}],"displaytype":"detail","filename":"20005-25-015.pdf","filesize":[{"value":"747.9 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"20005-25-015.pdf","url":"https://tokyo-metro-u.repo.nii.ac.jp/record/2871/files/20005-25-015.pdf"},"version_id":"123adb5d-3d52-4c74-886c-f752068aaa4f"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"permafrost environment","subitem_subject_scheme":"Other"},{"subitem_subject":"periglacial phenomena","subitem_subject_scheme":"Other"},{"subitem_subject":"pollen analysis","subitem_subject_scheme":"Other"},{"subitem_subject":"freezing and thawing indicies","subitem_subject_scheme":"Other"},{"subitem_subject":"forest tundra","subitem_subject_scheme":"Other"}]},"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":"Permafrost environment during the last glacial in east and north hokkaido, northernmost japan","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Permafrost environment during the last glacial in east and north hokkaido, northernmost japan"}]},"item_type_id":"3","owner":"3","path":["548"],"pubdate":{"attribute_name":"公開日","attribute_value":"2010-11-30"},"publish_date":"2010-11-30","publish_status":"0","recid":"2871","relation_version_is_last":true,"title":["Permafrost environment during the last glacial in east and north hokkaido, northernmost japan"],"weko_creator_id":"3","weko_shared_id":-1},"updated":"2023-06-19T18:26:31.282267+00:00"}
