The free-fall pop-up ocean-bottom seismograph has many merits compared with the anchored-bouy ocean-bottom seismograph commonly used in Japan. Two of its merits are that the size of this system is small and the weight is light. Ontheotherhand, one of its demerits relates to the difficulty involved in recovering OBS. The free-fall pop-up ocean-bottom seismograph is composed of a sensor and recording system, pressure case, release-mechanism, ballast, buoyant body, and a finding system. For our system, we developed a low-power recording device. Both syntactic foam and glass sphere were adapted in order to obtain a buoyant force. To increase the safety of the system, a double release-mechanism was adopted. A 27 MHZ radio beacon, and a flash beacon and flag were used as the finding system. A detailed description of the system is provided in this paper.","subitem_description_type":"Abstract"}]},"item_4_full_name_3":{"attribute_name":"著者別名","attribute_value_mlt":[{"nameIdentifiers":[{"nameIdentifier":"71106","nameIdentifierScheme":"WEKO"}],"names":[{"name":"Kasahara, Junzo"}]},{"nameIdentifiers":[{"nameIdentifier":"71107","nameIdentifierScheme":"WEKO"}],"names":[{"name":"Koresawa, Sadayuki"}]},{"nameIdentifiers":[{"nameIdentifier":"71108","nameIdentifierScheme":"WEKO"}],"names":[{"name":"Ouchi, Toru"}]},{"nameIdentifiers":[{"nameIdentifier":"71109","nameIdentifierScheme":"WEKO"}],"names":[{"name":"Nagumo, Shozaburo"}]}]},"item_4_identifier_registration":{"attribute_name":"ID登録","attribute_value_mlt":[{"subitem_identifier_reg_text":"10.15083/00032043","subitem_identifier_reg_type":"JaLC"}]},"item_4_publisher_20":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"東京大学地震研究所"}]},"item_4_source_id_10":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AN10165194","subitem_source_identifier_type":"NCID"}]},"item_4_subject_15":{"attribute_name":"日本十進分類法","attribute_value_mlt":[{"subitem_subject":"051.1","subitem_subject_scheme":"NDC"}]},"item_4_text_21":{"attribute_name":"出版者別名","attribute_value_mlt":[{"subitem_text_value":"Earthquake Research Institute, University of Tokyo"}]},"item_4_text_4":{"attribute_name":"著者所属","attribute_value_mlt":[{"subitem_text_value":"地震研究所"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"笠原, 順三"}],"nameIdentifiers":[{"nameIdentifier":"71102","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"是沢, 定之"}],"nameIdentifiers":[{"nameIdentifier":"71103","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"大内, 徹"}],"nameIdentifiers":[{"nameIdentifier":"71104","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"南雲, 昭三郎"}],"nameIdentifiers":[{"nameIdentifier":"71105","nameIdentifierScheme":"WEKO"}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2017-06-12"}],"displaytype":"detail","filename":"jis0130001.pdf","filesize":[{"value":"1.8 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"jis0130001.pdf","url":"https://repository.dl.itc.u-tokyo.ac.jp/record/32052/files/jis0130001.pdf"},"version_id":"c1dab73d-5b2d-49eb-b65b-54d49ff162a9"}]},"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":"自由落下・自己浮上方式海底地震計の開発","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"自由落下・自己浮上方式海底地震計の開発"}]},"item_type_id":"4","owner":"1","path":["4415","4416"],"pubdate":{"attribute_name":"公開日","attribute_value":"2010-12-22"},"publish_date":"2010-12-22","publish_status":"0","recid":"32052","relation_version_is_last":true,"title":["自由落下・自己浮上方式海底地震計の開発"],"weko_creator_id":"1","weko_shared_id":null},"updated":"2022-12-19T04:37:39.362196+00:00"}
