First, every relative velocity profile obtained with a fixed time interval in a down cast is transformed into an absolute velocity profile by adding the horizontal ADCP drift velocity at each time. Next, they are averaged for every depth and consequently a full absolute velocity profile is obtained. Here, the horizontal ADCP drift velocity at each time is estimated from the mean difference between the relative velocity profile at the time and the absolute velocity profiles at the adjoining times. For a starting point of the chain of process, absolute velocity profiles obtained by ADCP bottom tracking near a sea bottom are used. For accuracy evaluation, rms differences between the LADCP data and vessel-mounted ADCP data obtained in five observations are calculated. As a result, the rms differences classified by depth layer （36-500 m） and by observation are about 15 cm/sec in common.","subitem_description_language":"en","subitem_description_type":"Abstract"},{"subitem_description":"LADCP データの処理において，等時間間隔で得られた個々の相対流速プロファイルを，各時刻について推定した ADCP 水平移動速度を加算することにより絶対流速化し，これらを単位深度毎に平均して一つの流速プロファイルを得るという独自の方法を採用した。その際，ADCP のボトムトラッキングデータを使用した。得られたデータと船底 ADCP データとの差の rms 値は，各深度間および各調査航海間で違いは見られず，いずれも15 cm/sec 程度であった。","subitem_description_language":"ja","subitem_description_type":"Abstract"}]},"item_10002_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"水産総合研究センター","subitem_publisher_language":"ja"}]},"item_10002_relation_16":{"attribute_name":"情報源","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"fra_k_23_1","subitem_relation_type_select":"Local"}}]},"item_10002_relation_17":{"attribute_name":"関連サイト","attribute_value_mlt":[{"subitem_relation_name":[{"subitem_relation_name_text":"日本農学文献記事索引（AgriKnowledge）"}],"subitem_relation_type_id":{"subitem_relation_type_id_text":"https://agriknowledge.affrc.go.jp/RN/2010751351","subitem_relation_type_select":"URI"}}]},"item_10002_source_id_11":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AA11589591","subitem_source_identifier_type":"NCID"}]},"item_10002_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"1346-9894","subitem_source_identifier_type":"PISSN"}]},"item_10002_version_type_20":{"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_access_right":{"attribute_name":"アクセス権","attribute_value_mlt":[{"subitem_access_right":"open access","subitem_access_right_uri":"http://purl.org/coar/access_right/c_abf2"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorAffiliations":[{"affiliationNameIdentifiers":[],"affiliationNames":[{"affiliationName":"","affiliationNameLang":"ja"}]}],"creatorNames":[{"creatorName":"Saito, Tsutomu","creatorNameLang":"en"},{"creatorName":"斉藤, 勉","creatorNameLang":"ja"},{"creatorName":"サイトウ, ツトム","creatorNameLang":"ja-Kana"}],"familyNames":[{"familyName":"Saito","familyNameLang":"en"},{"familyName":"斉藤","familyNameLang":"ja"},{"familyName":"サイトウ","familyNameLang":"ja-Kana"}],"givenNames":[{"givenName":"Tsutomu","givenNameLang":"en"},{"givenName":"勉","givenNameLang":"ja"},{"givenName":"ツトム","givenNameLang":"ja-Kana"}],"nameIdentifiers":[{"nameIdentifier":"507","nameIdentifierScheme":"WEKO"},{"nameIdentifier":"30371884","nameIdentifierScheme":"e-Rad","nameIdentifierURI":"https://kaken.nii.ac.jp/ja/search/?qm=30371884"}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_access","date":[{"dateType":"Available","dateValue":"2024-10-02"}],"filename":"fra_k_23_1.pdf","filesize":[{"value":"711.3 KB"}],"format":"application/pdf","licensetype":"license_0","mimetype":"application/pdf","url":{"url":"https://fra.repo.nii.ac.jp/record/2010858/files/fra_k_23_1.pdf"},"version_id":"a695a90f-ff22-4030-bdd4-953075cc6e00"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"LADCP; data processing; accuracy evaluation","subitem_subject_language":"en","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":"ボトムトラッキングを用いた簡素なLADCPデータ処理方法","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"ボトムトラッキングを用いた簡素なLADCPデータ処理方法","subitem_title_language":"ja"},{"subitem_title":"Simple LADCP data processing method with bottom tracking","subitem_title_language":"en"}]},"item_type_id":"10002","owner":"10","path":["1724310836085"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2024-10-02"},"publish_date":"2024-10-02","publish_status":"0","recid":"2010858","relation_version_is_last":true,"title":["ボトムトラッキングを用いた簡素なLADCPデータ処理方法"],"weko_creator_id":"10","weko_shared_id":-1},"updated":"2025-03-27T04:50:54.744589+00:00"}
