More than 95% of dissolved inorganic nitrogen (DIN)was composed of NH4_4^+,but its contribution to total dissolved nitrogen (TDN) was only 10%, whereas that of dissolved organic nitrogen (DON) was achieved to 90%. We conducted a laboratory experiment to examine decomposition of DON and total organic nitrogen (TON) in the sediments. DON decreased 89 μmol N l^<-1> and NH_4^+ increased 212 μmol N l^<-1> during 14 days, though no significant change was detected as for TON. As a result, contribution of NH_4^+ to TDN was achieved to 90%, whereas that of DON was only 10%. It clearly contradicts to the field observation and suggests the process of NH_4^+ to remove most of NH_4^+ from the sediments. N_20 flux from the sediment to the atmosohere was estimated as 13.2 nmol m^<-2>d^<-1> using the data of the decomposition experiment, which is consistent with the values reported as for other mangrove areas.","subitem_description_type":"Abstract"}]},"item_25_identifier_registration":{"attribute_name":"ID登録","attribute_value_mlt":[{"subitem_identifier_reg_text":"10.14945/00000393","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":"110000961625","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":"羽川, 貴弘"}],"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":"KJ00000693009.pdf","filesize":[{"value":"1.0 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"KJ00000693009.pdf","url":"https://shizuoka.repo.nii.ac.jp/record/464/files/KJ00000693009.pdf"},"version_id":"967b9303-11fa-455e-ae5b-0e5282ec0248"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"mangrove","subitem_subject_scheme":"Other"},{"subitem_subject":"nitrogen cycle","subitem_subject_scheme":"Other"},{"subitem_subject":"remineralization of organic nitrogen","subitem_subject_scheme":"Other"},{"subitem_subject":"N_20 flux","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":"石垣島マングローブ域堆積物における窒素化合物の動態","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"石垣島マングローブ域堆積物における窒素化合物の動態"}]},"item_type_id":"25","owner":"3","path":["117"],"pubdate":{"attribute_name":"公開日","attribute_value":"2008-01-25"},"publish_date":"2008-01-25","publish_status":"0","recid":"464","relation_version_is_last":true,"title":["石垣島マングローブ域堆積物における窒素化合物の動態"],"weko_creator_id":"3","weko_shared_id":-1},"updated":"2024-02-19T05:38:17.766473+00:00"}
