Prior to the experiments, we measured water quality (temperature, salinity and dissolved oxygen concentration (DO)) to assess the hydrographic condition in this mooring place. Hydrographic parameters or recorded temperature and salinity in the area were higher and lower respectively, than those measured in Tokyo Bay (Stn. F3). These data indicate intrusion of effluent water from Wastewater Treatment Plant and Shinagawa and Oi Thermal Power Plant near the mooring place. Water column was stratified all year round and was hypoxic at the bottom during May-November 2006 and June-November 2007. In SSO experiments, the difference of DO between the inner and outer side of SSO apparatus was 0.91 mg L-1 in average. The trend of DO record traced at the SSO intake or the sea surface corresponded with that difference. When air flow rate was 1.0 L min-1 in MB experiments, DO near the sea bottom did not increase, due to large size bubbles rising from the bottom up to the upper layer. Conversely, the rising of bubbles was not observed, and DO modestly increased along same density layer when air flow rate was 0.2 L min-1. However it was not enough to improve hypoxia and further improvement is thus required.","subitem_description_type":"Abstract"}]},"item_6_description_6":{"attribute_name":"内容記述","attribute_value_mlt":[{"subitem_description":"東京海洋大学大学院海洋科学技術研究科 ","subitem_description_type":"Other"},{"subitem_description":"東京海洋大学大学院海洋科学技術研究科 ","subitem_description_type":"Other"},{"subitem_description":"東京海洋大学海洋科学部海洋環境学科 ","subitem_description_type":"Other"},{"subitem_description":"東京海洋大学海洋工学部海洋電子機械工学科 ","subitem_description_type":"Other"},{"subitem_description":"東京海洋大学大学院海洋科学技術研究科 ","subitem_description_type":"Other"},{"subitem_description":"東京水産大学水産学部海洋環境学科","subitem_description_type":"Other"}]},"item_6_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"東京海洋大学"}]},"item_6_source_id_11":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AA12066872","subitem_source_identifier_type":"NCID"}]},"item_6_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"2189-0951","subitem_source_identifier_type":"ISSN"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"小島, 諒子"},{"creatorName":"コジマ, リョウコ","creatorNameLang":"ja-Kana"},{"creatorName":"Kojima, Ryoko","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"遠矢, 亮 "},{"creatorName":"トオヤ, リョウ","creatorNameLang":"ja-Kana"},{"creatorName":"Toya, Ryo","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"石丸, 隆"},{"creatorName":"イシマル, タカシ","creatorNameLang":"ja-Kana"},{"creatorName":"Ishimaru, Takashi","creatorNameLang":"en"}],"nameIdentifiers":[{},{}]},{"creatorNames":[{"creatorName":"賞雅, 寛而"},{"creatorName":"タカマサ, トモジ","creatorNameLang":"ja-Kana"},{"creatorName":"Takamasa, Tomoji ","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"川上, 啓介"},{"creatorName":"カワカミ, ケイスケ","creatorNameLang":"ja-Kana"},{"creatorName":"Kawakami, Keisuke","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"大塚, 和臣"},{"creatorName":"オオツカ, カズオミ","creatorNameLang":"ja-Kana"},{"creatorName":"Otsuka, Kazuomi","creatorNameLang":"en"}],"nameIdentifiers":[{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2015-11-18"}],"displaytype":"detail","filename":"AA12066872-5-29.pdf","filesize":[{"value":"3.5 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"AA12066872-5-29.pdf","url":"https://oacis.repo.nii.ac.jp/record/352/files/AA12066872-5-29.pdf"},"version_id":"f54a2030-9baa-4aa5-86b9-01f26c4b8fcb"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"環境特性","subitem_subject_scheme":"Other"},{"subitem_subject":"貧酸素水塊","subitem_subject_scheme":"Other"},{"subitem_subject":"係船場","subitem_subject_scheme":"Other"},{"subitem_subject":"汽水域","subitem_subject_scheme":"Other"},{"subitem_subject":"溶存酸素","subitem_subject_scheme":"Other"},{"subitem_subject":"マイクロバブル","subitem_subject_scheme":"Other"},{"subitem_subject":"environmental capability","subitem_subject_scheme":"Other"},{"subitem_subject":"hypoxia","subitem_subject_scheme":"Other"},{"subitem_subject":"mooring place","subitem_subject_scheme":"Other"},{"subitem_subject":"brackish water area","subitem_subject_scheme":"Other"},{"subitem_subject":"dissolved oxygen","subitem_subject_scheme":"Other"},{"subitem_subject":"microbubble","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"}]},"item_title":"東京海洋大学品川キャンパス係船場の環境特性と貧酸素水塊改善の試み","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"東京海洋大学品川キャンパス係船場の環境特性と貧酸素水塊改善の試み"},{"subitem_title":"Approaches in improving hypoxia and environmental capability at a mooring place in Shinagawa campus of Tokyo University of Marine Science and Technology","subitem_title_language":"en"}]},"item_type_id":"6","owner":"3","path":["137"],"pubdate":{"attribute_name":"公開日","attribute_value":"2009-05-08"},"publish_date":"2009-05-08","publish_status":"0","recid":"352","relation_version_is_last":true,"title":["東京海洋大学品川キャンパス係船場の環境特性と貧酸素水塊改善の試み"],"weko_creator_id":"3","weko_shared_id":3},"updated":"2023-07-25T10:54:42.111726+00:00"}
