The sea bed was covered by silt and the more fine particles spreading tonguelikely from southeast to northwest. It is demonstrated that the 20 minutes mean vertical velocity is induced by horizontal current acrossing the isobath. The vertical change of 25 hours mean horizontal current can be well explained by the bottom Ekman layer theory with vertical eddy kinematic viscosity of 0.90cm^2/sec, and the bottom shear stress is estimated to be 0.037dyne/cm^2 northwestward. From the along-isobath component of 25 hours mean total shear Reynolds stress including tidal and turbulent current fluctuations, the vertical eddy kinematic viscosity is estimated to be 27cm^2/sec at 221.5cm above the sea bed and 105cm^2/sec at 135.5cm. The 20 minutes mean turbulent shear Reynolds stresses have large measurement error due to fluctuation of vertical velocity induced by bottom topography and do not have good correlation with vertical shear of horizontal velocity.","subitem_description_type":"Other"},{"subitem_description":"海底境界層内での剪断レイノルズ応力と底泥の粒度分布との対応を種々の海域で調べる手始めとして,1990年11月に九州南部陸棚縁辺の水深220mの地点の海底上105cm,166cm,277cmで1昼夜の間,電磁流速計で2秒毎に水平2成分と鉛直成分の流速変動を測定するとともに,周辺で底泥を採集した。当海域の底質は砂質であり,中央粒径値の分布図は細粒子域の南東角から北西方へ舌状の張り出しを示唆していた。20分平均鉛直流速の変動は海底傾斜の影響を受けて水平流速変動によって引き起こされることが示された。25時間平均恒流の大きさと向きの深さ方向への変化は鉛直渦動粘性係数を0.90cm^2/secとした海底エクマン境界層モデルで良く説明でき,恒流の鉛直シアーによる海底での剪断摩擦応力は北西向きに0.037dyne/cm^2と見積もられた。他方,等深線に平行する向きの成分の剪断レイノルズ応力と水平流速の鉛直シアーの各々の25時間平均値から求めた鉛直渦動粘性係数は上層で27cm^2/sec,下層で105cm^2/secと見積もられた。","subitem_description_type":"Other"}]},"item_7_full_name_2":{"attribute_name":"著者よみ","attribute_value_mlt":[{"nameIdentifiers":[{}],"names":[{"name":"イチカワ, ヒロシ"}]},{"nameIdentifiers":[{}],"names":[{"name":"フジモト, ケンジ"}]},{"nameIdentifiers":[{}],"names":[{"name":"ヒガシカワ, セイジ"}]},{"nameIdentifiers":[{}],"names":[{"name":"ウチヤマ, マサキ"}]},{"nameIdentifiers":[{}],"names":[{"name":"ヒダカ, マサヤス"}]},{"nameIdentifiers":[{}],"names":[{"name":"タカオカ, カツヨシ"}]}]},"item_7_full_name_3":{"attribute_name":"別言語の著者","attribute_value_mlt":[{"nameIdentifiers":[{}],"names":[{"name":"ICHIKAWA, Hiroshi"}]},{"nameIdentifiers":[{}],"names":[{"name":"FUJIMOTO, Kenji"}]},{"nameIdentifiers":[{}],"names":[{"name":"HIGASHIKAWA, Seiji"}]},{"nameIdentifiers":[{}],"names":[{"name":"UCHIYAMA, Masaki"}]},{"nameIdentifiers":[{}],"names":[{"name":"HIDAKA, Masayasu"}]},{"nameIdentifiers":[{}],"names":[{"name":"TAKAOKA, Katsuyoshi"}]},{"nameIdentifiers":[{}],"names":[{"name":"日髙, 正康"}]}]},"item_7_publisher_23":{"attribute_name":"公開者・出版者","attribute_value_mlt":[{"subitem_publisher":"鹿児島大学"}]},"item_7_source_id_7":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"0453087X","subitem_source_identifier_type":"ISSN"}]},"item_7_source_id_9":{"attribute_name":"NII書誌ID","attribute_value_mlt":[{"subitem_source_identifier":"AN00040498","subitem_source_identifier_type":"NCID"}]},"item_7_subject_15":{"attribute_name":"NDC","attribute_value_mlt":[{"subitem_subject":"660","subitem_subject_scheme":"NDC"}]},"item_7_text_24":{"attribute_name":"公開者よみ","attribute_value_mlt":[{"subitem_text_value":"カゴシマ ダイガク"}]},"item_7_text_25":{"attribute_name":"公開者別名","attribute_value_mlt":[{"subitem_text_value":"Kagoshima University"}]},"item_7_version_type_14":{"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":"市川, 洋"}],"nameIdentifiers":[{},{}]},{"creatorNames":[{"creatorName":"藤本, 顕治"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"東川, 勢二"}],"nameIdentifiers":[{},{}]},{"creatorNames":[{"creatorName":"内山, 正樹"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"日高, 正康"}],"nameIdentifiers":[{},{}]},{"creatorNames":[{"creatorName":"高岡, 勝義"}],"nameIdentifiers":[{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2016-10-28"}],"displaytype":"detail","filename":"AN00040498_v41_p27-44.pdf","filesize":[{"value":"1.6 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"AN00040498_v41_p27-44.pdf","url":"https://ir.kagoshima-u.ac.jp/record/5037/files/AN00040498_v41_p27-44.pdf"},"version_id":"a471314c-2e5a-4f11-bb3b-13fb3883673d"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"Benthic Boundary Layer","subitem_subject_scheme":"Other"},{"subitem_subject":"Bottom Stress","subitem_subject_scheme":"Other"},{"subitem_subject":"Reynolds Stress","subitem_subject_scheme":"Other"},{"subitem_subject":"Bottom Sediments","subitem_subject_scheme":"Other"},{"subitem_subject":"Current measurement","subitem_subject_scheme":"Other"},{"subitem_subject":"South of Kyushu","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":"陸棚縁辺部の海底直上における流れ","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"陸棚縁辺部の海底直上における流れ"}]},"item_type_id":"7","owner":"3","path":["40","4605"],"pubdate":{"attribute_name":"公開日","attribute_value":"2015-05-01"},"publish_date":"2015-05-01","publish_status":"0","recid":"5037","relation_version_is_last":true,"title":["陸棚縁辺部の海底直上における流れ"],"weko_creator_id":"3","weko_shared_id":3},"updated":"2024-01-30T05:47:10.857699+00:00"}
