Negative relationships between nutrient concentrations and temperature were observed in the surface water for a range from 5 to 15˚C in nitrate-N and silicate-Si, and from 5 to 20℃ in phosphate-P, respectively. Based on the physical characteristics of water, this region was divided into five areas: Oyashio, Kuroshio, Warm Core Ring, Okhotsk and Kurile Islands areas. Abundant nutrients were observed in the Warm Core Ring and the Kurile Islands area compared with the other three areas. Atom ratio of nutrients (N: Si: P) was variable in the surface water compared with a relatively constant value (N: Si: P=15: 22: 1) at 800m. Nutroclines were well developed within thermocline and pycnocline at most stations. However nutroclines for three nutrient species were deeper than thermocline and pycnocline in the Kuroshio area. The mean ratio of gradients of nutrocline as N: Si: P was 14: 22: 1 in the region studied. When this ratio was compared with the Redfield ratio, this ratio suggests that silicate-Si may be supplied exessively compared with the supply of nitrate-N and phosphate-P to the surface layer. Particularly this phenomenon was remarkable in the Okhotsk area. The reason for the ample supply of silicate-Si in the Okhotsk area is discussed.","subitem_description_language":"en","subitem_description_type":"Abstract"}]},"item_10002_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"北海道区水産研究所","subitem_publisher_language":"ja"},{"subitem_publisher":"Hokkaido National Fisheries Research Institute","subitem_publisher_language":"en"}]},"item_10002_relation_16":{"attribute_name":"情報源","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"hnf_k_56_4","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_language":"ja","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/2010501391","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":"AN1015410X","subitem_source_identifier_type":"NCID"}]},"item_10002_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"0513-2541","subitem_source_identifier_type":"PISSN"}]},"item_access_right":{"attribute_name":"アクセス権","attribute_value_mlt":[{"subitem_access_right":"metadata only access","subitem_access_right_uri":"http://purl.org/coar/access_right/c_14cb"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"葛西, 広海","creatorNameLang":"ja"},{"creatorName":"カサイ, ヒロミ","creatorNameLang":"ja-Kana"},{"creatorName":"Kasai, Hiromi","creatorNameLang":"en"}],"familyNames":[{"familyName":"葛西","familyNameLang":"ja"},{"familyName":"カサイ","familyNameLang":"ja-Kana"},{"familyName":"Kasai","familyNameLang":"en"}],"givenNames":[{"givenName":"広海","givenNameLang":"ja"},{"givenName":"ヒロミ","givenNameLang":"ja-Kana"},{"givenName":"Hiromi","givenNameLang":"en"}]},{"creatorNames":[{"creatorName":"齊藤, 宏明","creatorNameLang":"ja"},{"creatorName":"サイトウ, ヒロアキ","creatorNameLang":"ja-Kana"},{"creatorName":"Saito, Hiroaki","creatorNameLang":"en"}],"familyNames":[{"familyName":"齊藤","familyNameLang":"ja"},{"familyName":"サイトウ","familyNameLang":"ja-Kana"},{"familyName":"Saito","familyNameLang":"en"}],"givenNames":[{"givenName":"宏明","givenNameLang":"ja"},{"givenName":"ヒロアキ","givenNameLang":"ja-Kana"},{"givenName":"Hiroaki","givenNameLang":"en"}]},{"creatorNames":[{"creatorName":"田口, 哲","creatorNameLang":"ja"},{"creatorName":"タグチ, サトル","creatorNameLang":"ja-Kana"},{"creatorName":"Taguchi, Satoru","creatorNameLang":"en"}],"familyNames":[{"familyName":"田口","familyNameLang":"ja"},{"familyName":"タグチ","familyNameLang":"ja-Kana"},{"familyName":"Taguchi","familyNameLang":"en"}],"givenNames":[{"givenName":"哲","givenNameLang":"ja"},{"givenName":"サトル","givenNameLang":"ja-Kana"},{"givenName":"Satoru","givenNameLang":"en"}]}]},"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":"1990年8-9月の千島列島周辺海域における栄養塩分布特性","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"1990年8-9月の千島列島周辺海域における栄養塩分布特性","subitem_title_language":"ja"},{"subitem_title":"Nutrient distribution around the Kurile Islands in August and September, 1990","subitem_title_language":"en"}]},"item_type_id":"10002","owner":"10","path":["1716950587014"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2024-04-08"},"publish_date":"2024-04-08","publish_status":"0","recid":"2001692","relation_version_is_last":true,"title":["1990年8-9月の千島列島周辺海域における栄養塩分布特性"],"weko_creator_id":"10","weko_shared_id":-1},"updated":"2025-01-20T02:19:26.824246+00:00"}
