Vertical profiles of water flow inside the seagrass beds and a sand bed were investigated using gypsum balls. Water flow inside beds of Enhalus acoroides (L.f.) Royle, which has large blades, was much smaller than that inside beds of Thalassia hemprichii (Ehrenb.) Aschers. and Halophila ovalis (R.Br.) Hook. f., which have small blades, or in the sand bed. The sedimentation rate measured with sediment traps inside the E. acoroides beds was greater than that inside the T. hemprichii beds at each station. The percentage of mud in the sediments inside an E. acoroides patch was higher than that outside it at the same station. Negatively proportional to water flow, the phi median diameters of sediments in the Enhalus beds were greater than those in the sand (unvegatated area) or Thalassia beds at the same station. These facts suggest that the vertical reduction in water flow depends on differences in the formation of seagrass meadows, and the sedimentation rate and sediment composition are influenced by the retardation of the water flow by the seagrass meadows.","subitem_description_type":"Abstract"}]},"item_4_identifier_registration":{"attribute_name":"ID登録","attribute_value_mlt":[{"subitem_identifier_reg_text":"10.15083/00040824","subitem_identifier_reg_type":"JaLC"}]},"item_4_publisher_20":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"International Coastal Research Center, Ocean Research Institute, the University of Tokyo"}]},"item_4_source_id_10":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AA11957899","subitem_source_identifier_type":"NCID"}]},"item_4_source_id_8":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"13493000","subitem_source_identifier_type":"ISSN"}]},"item_4_subject_15":{"attribute_name":"日本十進分類法","attribute_value_mlt":[{"subitem_subject":"452","subitem_subject_scheme":"NDC"}]},"item_4_text_21":{"attribute_name":"出版者別名","attribute_value_mlt":[{"subitem_text_value":"東京大学海洋研究所国際沿岸海洋研究センター"}]},"item_4_text_4":{"attribute_name":"著者所属","attribute_value_mlt":[{"subitem_text_value":"Ocean Research Institute, University of Tokyo"},{"subitem_text_value":"Graduate School of Science and Technology, Chiba University"},{"subitem_text_value":"Faculty of Fisheries, Kasetsart University"},{"subitem_text_value":"Center for Marine Environmental Studies, Ehime University"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"Komatsu, Teruhisa"}],"nameIdentifiers":[{"nameIdentifier":"139729","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Umezawa, Yu"}],"nameIdentifiers":[{"nameIdentifier":"139730","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Nakakoka, Masahiro"}],"nameIdentifiers":[{"nameIdentifier":"139731","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Supanwanid, Chatcharee"}],"nameIdentifiers":[{"nameIdentifier":"139732","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Kanamoto, Ziyusei"}],"nameIdentifiers":[{"nameIdentifier":"139733","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":"2017-06-27"}],"displaytype":"detail","filename":"KJ00004098941.pdf","filesize":[{"value":"923.4 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"KJ00004098941.pdf","url":"https://repository.dl.itc.u-tokyo.ac.jp/record/40833/files/KJ00004098941.pdf"},"version_id":"14d100c3-3948-40b5-a3f7-fef74e6634b6"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"water flow","subitem_subject_scheme":"Other"},{"subitem_subject":"plaster ball","subitem_subject_scheme":"Other"},{"subitem_subject":"seagrass","subitem_subject_scheme":"Other"},{"subitem_subject":"sediment","subitem_subject_scheme":"Other"},{"subitem_subject":"sedimentation","subitem_subject_scheme":"Other"},{"subitem_subject":"Enhalus acoroides","subitem_subject_scheme":"Other"},{"subitem_subject":"Halophila ovalis","subitem_subject_scheme":"Other"},{"subitem_subject":"Thalassia hemprichii","subitem_subject_scheme":"Other"},{"subitem_subject":"Andaman Sea","subitem_subject_scheme":"Other"},{"subitem_subject":"Thailand","subitem_subject_scheme":"Other"}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"eng"}]},"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":"Water flow and sediment in Enhalus acoroides and other seagrass beds in the Andaman Sea, off Khao Bae Na, Thailand","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Water flow and sediment in Enhalus acoroides and other seagrass beds in the Andaman Sea, off Khao Bae Na, Thailand"}]},"item_type_id":"4","owner":"1","path":["7211","7210"],"pubdate":{"attribute_name":"公開日","attribute_value":"2007-04-05"},"publish_date":"2007-04-05","publish_status":"0","recid":"40833","relation_version_is_last":true,"title":["Water flow and sediment in Enhalus acoroides and other seagrass beds in the Andaman Sea, off Khao Bae Na, Thailand"],"weko_creator_id":"1","weko_shared_id":null},"updated":"2022-12-19T04:16:26.238710+00:00"}
