To perform very long ocean bottom experiments of more than one year, there remains difficulty in the trade-off between physical size and lifetime in developing a battery system. A seawater battery solves this problem. In this paper we report the results of performance tests on the Kongsberg Simrad seawater battery system SWB 600 carried out from beginning of Dec. 1998, in the Sea around Japan. This battery has a magnesium rod anode, and a cathode composed of a carbon fiber assembly. In performance tests, a set of nine parallel cement-resistors of 10 ohm was used. Voltage generated by the SWB 600 was measured during the experiment. Just after being dipped in sea water, the battery began to produce electric power with a voltage of about 1.8V, which corresponds to 3W. At an ocean bottom depth of 692m, the voltage produced by the SWB 600 was about 1.5V, and the corresponding power was 2W. Because the amount of dissolved oxygen is one of the important factors in generating electric power, further knowledge about the chemical properties of sea water may be needed for actual observations.","subitem_description_type":"Abstract"}]},"item_4_full_name_3":{"attribute_name":"著者別名","attribute_value_mlt":[{"nameIdentifiers":[{"nameIdentifier":"126608","nameIdentifierScheme":"WEKO"}],"names":[{"name":"Watanabe, Tomoki"}]},{"nameIdentifiers":[{"nameIdentifier":"126609","nameIdentifierScheme":"WEKO"}],"names":[{"name":"Mochizuki, Masashi"}]},{"nameIdentifiers":[{"nameIdentifier":"126610","nameIdentifierScheme":"WEKO"}],"names":[{"name":"Shiobara, Hajime"}]},{"nameIdentifiers":[{"nameIdentifier":"126611","nameIdentifierScheme":"WEKO"}],"names":[{"name":"Kanazawa, Toshihiko"}]}]},"item_4_identifier_registration":{"attribute_name":"ID登録","attribute_value_mlt":[{"subitem_identifier_reg_text":"10.15083/0000032658","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":"AN00162258","subitem_source_identifier_type":"NCID"}]},"item_4_source_id_8":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"00408972","subitem_source_identifier_type":"ISSN"}]},"item_4_subject_15":{"attribute_name":"日本十進分類法","attribute_value_mlt":[{"subitem_subject":"453","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":"海半球観測研究センター"},{"subitem_text_value":"富山大学理学部"},{"subitem_text_value":"地震地殻変動観測センター"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"渡邊, 智毅"}],"nameIdentifiers":[{"nameIdentifier":"126604","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"望月, 将志"}],"nameIdentifiers":[{"nameIdentifier":"126605","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"塩原, 肇"}],"nameIdentifiers":[{"nameIdentifier":"126606","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"金沢, 敏彦"}],"nameIdentifiers":[{"nameIdentifier":"126607","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":"2017-06-26"}],"displaytype":"detail","filename":"ji0743002.pdf","filesize":[{"value":"1.1 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"ji0743002.pdf","url":"https://repository.dl.itc.u-tokyo.ac.jp/record/32658/files/ji0743002.pdf"},"version_id":"f72cba8a-206a-4cc4-871d-cc219f82302a"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"seawater battery","subitem_subject_scheme":"Other"},{"subitem_subject":"long-term ocean bottom observation","subitem_subject_scheme":"Other"},{"subitem_subject":"Kongsberg Simrad SWB600","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":"マグネシウム海水電池の特性について","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"マグネシウム海水電池の特性について","subitem_title_language":"ja"}]},"item_type_id":"4","owner":"1","path":["4658","4660"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2008-05-30"},"publish_date":"2008-05-30","publish_status":"0","recid":"32658","relation_version_is_last":true,"title":["マグネシウム海水電池の特性について"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2022-12-19T05:17:20.277926+00:00"}
