The vessel is considered as a suitable monitoring platform for sea ice. Not only basic information such as ice thickness and snow depth, but also ramming icebreaking data have been analyzed. In particular, the penetrating distances by ramming reflect difficulty in ice navigation and show distinctly interannual variations from 1983 to 2002. The periods with longer distances are consistent with those when breakup of landfast ice occurred frequently in the bay. The penetrating distances have shown a tendency to increase since the end of the 1990s, when ice breakup has been pronounced.","subitem_description_type":"Other"}]},"item_1_identifier_registration":{"attribute_name":"ID登録","attribute_value_mlt":[{"subitem_identifier_reg_text":"10.15094/00009295","subitem_identifier_reg_type":"JaLC"}]},"item_1_source_id_13":{"attribute_name":"雑誌書誌ID","attribute_value_mlt":[{"subitem_source_identifier":"AN00181831","subitem_source_identifier_type":"NCID"}]},"item_1_source_id_20":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"00857289","subitem_source_identifier_type":"ISSN"}]},"item_1_subject_21":{"attribute_name":"国際十進分類法","attribute_value_mlt":[{"subitem_subject":"551.46","subitem_subject_scheme":"UDC"}]},"item_1_text_10":{"attribute_name":"著者所属(英)","attribute_value_mlt":[{"subitem_text_language":"en","subitem_text_value":"National Institute of Polar Research, Research Organization of Information Systems/National Maritime Research Institute/National Maritime Research Institute/National Maritime Research Institute/National Institute of Polar Research, Research Organization of Information Systems"}]},"item_1_text_9":{"attribute_name":"著者所属(日)","attribute_value_mlt":[{"subitem_text_value":"情報・システム研究機構国立極地研究所/海上技術安全研究所/海上技術安全研究所/海上技術安全研究所/情報・システム研究機構国立極地研究所"}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2004-11-30"}],"displaytype":"detail","filename":"KJ00002361439.pdf","filesize":[{"value":"1.2 MB"}],"format":"application/pdf","licensetype":"license_6","mimetype":"application/pdf","url":{"label":"KJ00002361439","url":"https://nipr.repo.nii.ac.jp/record/9295/files/KJ00002361439.pdf"},"version_id":"575dba39-7269-4a7f-bbf8-b7d122ccb45a"}]},"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":"「しらせ」砕氷航行データが示す南極リュツォ・ホルム湾定着氷の年々変化","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"「しらせ」砕氷航行データが示す南極リュツォ・ホルム湾定着氷の年々変化"},{"subitem_title":"Interannual variation of landfast ice condition in Lutzow-Holmbukta, Antarctica, derived from navigation log of icebreaker Shirase","subitem_title_language":"en"}]},"item_type_id":"1","owner":"4","path":["1141"],"pubdate":{"attribute_name":"公開日","attribute_value":"2004-11-30"},"publish_date":"2004-11-30","publish_status":"0","recid":"9295","relation_version_is_last":true,"title":["「しらせ」砕氷航行データが示す南極リュツォ・ホルム湾定着氷の年々変化"],"weko_creator_id":"4","weko_shared_id":4},"updated":"2023-07-25T14:20:50.202135+00:00"}
