The entire original land area was covered by lava, as well as by thick deposits of volcanic ash that have reset the land surface. As an uninhabited island isolated in the Pacific Ocean and 130 km apart from the nearest land, it offers an unique opportunity to observe primary succession on an oceanic island without human impacts. Thus, it is important to conduct comprehensive field surveys on its biota, geology and volcanic activities immediately after the eruption in order to understand the formation process of the volcanic island, the impact of the eruption on the biota, and the situations at the start of primary succession. Therefore, a comprehensive scientific survey was planned to record the latest information on the nature of Nishinoshima Island and assess its scientific value. It was conducted twice, in July and September 2021, following the 2019 survey. This is the first survey of marine biota around Nishinoshima Island, and UAVs and AUVs were also actively used to conduct the survey safely during volcanic activity. The survey was carried out in collaboration with the Ministry of the Environment, the University of Tokyo and the Japan Broadcasting Corporation (NHK). In carrying out the survey, sufficient attention was paid to safety management on the volcanically active island, and quarantine was also strictly enforced as a measure to prevent the invasion of alien species in order to eliminate any human impact of the survey.","subitem_description_language":"en","subitem_description_type":"Abstract"}]},"item_30002_file35":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2023-11-28"}],"displaytype":"detail","filename":"20001-049-001.pdf","format":"application/pdf","mimetype":"application/pdf","url":{"objectType":"fulltext","url":"https://tokyo-metro-u.repo.nii.ac.jp/record/2000070/files/20001-049-001.pdf"},"version_id":"e0b4098c-eb76-482c-bf09-2f113b06ff23"}]},"item_30002_language12":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"jpn"}]},"item_30002_publisher10":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"東京都立大学小笠原研究委員会","subitem_publisher_language":"ja"}]},"item_30002_resource_type13":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"resourcetype":"departmental bulletin paper","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_30002_source_identifier22":{"attribute_name":"収録物識別子","attribute_value_mlt":[{"subitem_source_identifier":"03868176","subitem_source_identifier_type":"PISSN"},{"subitem_source_identifier":"AN00032332","subitem_source_identifier_type":"NCID"}]},"item_30002_subject8":{"attribute_name":"主題","attribute_value_mlt":[{"subitem_subject":"安全管理","subitem_subject_language":"ja","subitem_subject_scheme":"Other"},{"subitem_subject":"一次遷移","subitem_subject_language":"ja","subitem_subject_scheme":"Other"},{"subitem_subject":"遠隔離島","subitem_subject_language":"ja","subitem_subject_scheme":"Other"},{"subitem_subject":"小笠原諸島","subitem_subject_language":"ja","subitem_subject_scheme":"Other"},{"subitem_subject":"外来種侵入防止対策","subitem_subject_language":"ja","subitem_subject_scheme":"Other"},{"subitem_subject":"Ogasawara Islands","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Primary succession","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Quarantine","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Remote island","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Safety management","subitem_subject_language":"en","subitem_subject_scheme":"Other"}]},"item_30002_title0":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"2021年における西之島総合学術調査の概略","subitem_title_language":"ja"},{"subitem_title":"Overview of the Nishinoshima comprehensive scientific research project, in 2021","subitem_title_language":"en"}]},"item_30002_version_type15":{"attribute_name":"出版タイプ","attribute_value_mlt":[{"subitem_version_resource":"http://purl.org/coar/version/c_970fb48d4fbd8a85","subitem_version_type":"VoR"}]},"item_title":"2021年における西之島総合学術調査の概略","item_type_id":"30002","owner":"14","path":["1701390537003"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2023-11-28"},"publish_date":"2023-11-28","publish_status":"0","recid":"2000070","relation_version_is_last":true,"title":["2021年における西之島総合学術調査の概略"],"weko_creator_id":"14","weko_shared_id":-1},"updated":"2023-12-11T02:53:42.148550+00:00"}
