The observatory's history can be divided into three stages, i.e., 1970-1980, 1981-1987, and 1988 to present. In the first stage, geomagnetic total intensity and three component variations were recorded in a digital form by a printer, as well as monitor recordings on strip charts. In 1981, a cassette tape recording system was introduced, which was improved to a telemetry system in 1984. The present system, since 1988, consists of a proton precession magnetometer, an Overhauser magnetometer, two three-component fluxgate variometers, with a telemetry system and a backup power supply. The observatory also has five satellite magnetic stations in the Tokai district to study the regional characteristics of the geomagnetic secular variations. Although it started as a geomagnetic observatory, its name was changed to Yatsugatake Geo-Electromagnetic Observatory in 1994 because of increased importance of electromagnetic observations.","subitem_description_type":"Abstract"}]},"item_4_description_6":{"attribute_name":"内容記述","attribute_value_mlt":[{"subitem_description":"＜論説＞","subitem_description_type":"Other"}]},"item_4_full_name_3":{"attribute_name":"著者別名","attribute_value_mlt":[{"nameIdentifiers":[{"nameIdentifier":"72209","nameIdentifierScheme":"WEKO"}],"names":[{"name":"KOYAMA, Shigeru"}]}]},"item_4_identifier_registration":{"attribute_name":"ID登録","attribute_value_mlt":[{"subitem_identifier_reg_text":"10.15083/00032293","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":"AA11286807","subitem_source_identifier_type":"NCID"}]},"item_4_source_id_8":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"13426486","subitem_source_identifier_type":"ISSN"}]},"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":"八ヶ岳地球電磁気観測所, (東京大学地震研究所)"},{"subitem_text_value":"Yatsugatake Geo-Electromagnetic Observatory, (Earthquake Research Institute, University of Tokyo)"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"小山, 茂"}],"nameIdentifiers":[{"nameIdentifier":"72208","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":"01_023-029.pdf","filesize":[{"value":"13.7MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"01_023-029.pdf","url":"https://repository.dl.itc.u-tokyo.ac.jp/record/32302/files/01_023-029.pdf"},"version_id":"e9b212b2-c711-4d64-9bc4-6c18a232b5d5"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"Yatsugatake Geomagnetic Observatory","subitem_subject_scheme":"Other"},{"subitem_subject":"Yatsugatake Geo-Electromagnetic Observatory","subitem_subject_scheme":"Other"},{"subitem_subject":"electromagnetic observation","subitem_subject_scheme":"Other"}]},"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":"八ヶ岳地球電磁気観測所の観測システムの変遷と現状","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"八ヶ岳地球電磁気観測所の観測システムの変遷と現状","subitem_title_language":"ja"}]},"item_type_id":"4","owner":"1","path":["4497","4498"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2017-05-15"},"publish_date":"2017-05-15","publish_status":"0","recid":"32302","relation_version_is_last":true,"title":["八ヶ岳地球電磁気観測所の観測システムの変遷と現状"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2022-12-19T04:08:26.608119+00:00"}
