In tropical and subtropical coastal region, mangroves are actively fixing CO_2 by photosynthesis and regarded as a significant CO_2 Sink. On the other hand, it is known that mangrove sediment releases CH_4 to atmosphere. Due to O_2 deficiency in the sediment, which is caused by redundant supply of organic matter and seawater flooding the sediment. Although CH_4 released from natural wetland occupies 20% for all of CH_4 production, pathway and condition of the CH_4 production are still unclear. In this work, we study behavior of organic matter in mangrove sediment, in particular accumulation of organic matter and CH_4 release, at the mouth of Fukido River, Ishigaki Island, Okinawa Prefecture. Although pH was the optimum condition for methanogenesis bacteria (pH 6.4-7.4), redox potential was very high (+185 - +240mV). Total organic carbon in sediment was 6.2±2.7% for sediment dry weight, which shows that this mangrove forest stores much abundant carbon in sediment. The CH_4 release rate in vitro experiment was 118μmol m^<-2>day^<-1>. This value is negligible compared with total organic carbon reduction rate (2.1mol m^<-2>day^<-l>). This suggests that CH_4 produced by decomposition of organic matter is minor or that CH_4 is immediately oxidized in sediment.","subitem_description_type":"Abstract"}]},"item_25_identifier_registration":{"attribute_name":"ID登録","attribute_value_mlt":[{"subitem_identifier_reg_text":"10.14945/00000390","subitem_identifier_reg_type":"JaLC"}]},"item_25_publisher_6":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"静岡大学地球科学教室"}]},"item_25_relation_22":{"attribute_name":"NII論文ID","attribute_value_mlt":[{"subitem_relation_type":"isIdenticalTo","subitem_relation_type_id":{"subitem_relation_type_id_text":"110000413413","subitem_relation_type_select":"NAID"}}]},"item_25_source_id_19":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"03886298","subitem_source_identifier_type":"ISSN"}]},"item_25_source_id_23":{"attribute_name":"NII書誌ID","attribute_value_mlt":[{"subitem_source_identifier":"AN00103190","subitem_source_identifier_type":"NCID"}]},"item_25_subject_8":{"attribute_name":"NDC","attribute_value_mlt":[{"subitem_subject":"450","subitem_subject_scheme":"NDC"}]},"item_25_version_type_32":{"attribute_name":"著者版フラグ","attribute_value_mlt":[{"subitem_version_resource":"http://purl.org/coar/version/c_970fb48d4fbd8a85","subitem_version_type":"VoR"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"八巻, 美樹"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"鈴木, 款"}],"nameIdentifiers":[{},{},{},{}]},{"creatorNames":[{"creatorName":"宮坂, 均"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"松井, 直弘"}],"nameIdentifiers":[{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2017-12-14"}],"displaytype":"detail","filename":"KJ00000102489.pdf","filesize":[{"value":"761.4 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"KJ00000102489.pdf","url":"https://shizuoka.repo.nii.ac.jp/record/454/files/KJ00000102489.pdf"},"version_id":"8d71c33f-7302-467c-aaac-bd3554ab14ab"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"mangrove","subitem_subject_scheme":"Other"},{"subitem_subject":"methane flux","subitem_subject_scheme":"Other"},{"subitem_subject":"organic carbon","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":"マングローブ林堆積物における有機物とメタンの動態","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"マングローブ林堆積物における有機物とメタンの動態"}]},"item_type_id":"25","owner":"3","path":["116"],"pubdate":{"attribute_name":"公開日","attribute_value":"2008-01-25"},"publish_date":"2008-01-25","publish_status":"0","recid":"454","relation_version_is_last":true,"title":["マングローブ林堆積物における有機物とメタンの動態"],"weko_creator_id":"3","weko_shared_id":-1},"updated":"2024-02-19T05:38:29.439452+00:00"}
