Precipitation is considered one of the supply mechanisms; however, the appropriate evaluation of nutrient concentrations of precipitation has not been undertaken to date. Focusing on the nutrients of the precipitation origin, rainwater samples were collected every 1 mm of rainfall by compact, lightweight, and non-powered equipment for approximately a year. Nitrate, nitrite, ammonia, phosphate, and silicic acid concentrations were measured in the obtained samples. Concentrations of nitrate and ammonia were generally high in the early falling rain (water) and showed a decreasing trend in the subsequent precipitation. This was caused by the concentration of nitrogen compounds in the atmosphere melting down as the raindrops fall. Although regional fluctuations must be considered, it was estimated that an inorganic nitrogen concentration of approximately 2μM would increase up to 50 cm beneath the sea surface assuming a precipitation of 50 mm.","subitem_description_language":"en","subitem_description_type":"Abstract"},{"subitem_description":"海域への栄養塩類供給機構の一つとして降雨が考えられるが，雨水自体の栄養塩濃度等の把握は十分とは言い難い。本調査では，雨水起源の栄養塩類に焦点を当て，小型・軽量かつ無動力で稼働する安価な機器を使用して，降水量 1mm毎に細分して雨水を採取し，試水中の硝酸塩亜硝酸塩，アンモニア，リン酸塩およびケイ酸を定量した。その結果，概ね硝酸塩とアンモニアが降り始めの雨水中で高い値を示し，その後減少する傾向を示した。これは，大気中の窒素化合物等を雨水が溶かし込んで落下することに起因するものと考えられる。また 50mmの降水量を仮定すると，海面下50cmでは窒素態栄養塩で約 2μMの濃度上昇が起こることが期待された。","subitem_description_language":"ja","subitem_description_type":"Abstract"}]},"item_10001_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"水産研究・教育機構","subitem_publisher_language":"ja"},{"subitem_publisher":"Japan Fisheries Research and Education Agency","subitem_publisher_language":"en"}]},"item_10001_relation_16":{"attribute_name":"情報源","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"fra_t_11_1_31","subitem_relation_type_select":"Local"}}]},"item_10001_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/2010926752","subitem_relation_type_select":"URI"}}]},"item_10001_source_id_11":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AA12359338","subitem_source_identifier_type":"NCID"}]},"item_10001_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"1883-2253","subitem_source_identifier_type":"PISSN"}]},"item_10001_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":[{"creatorNames":[{"creatorName":"阿部, 和雄","creatorNameLang":"ja"}],"familyNames":[{"familyName":"阿部","familyNameLang":"ja"}],"givenNames":[{"givenName":"和雄","givenNameLang":"ja"}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_access","date":[{"dateType":"Available","dateValue":"2024-08-06"}],"filename":"fra_t_11_1_31.pdf","format":"application/pdf","licensetype":"license_0","mimetype":"application/pdf","url":{"url":"https://fra.repo.nii.ac.jp/record/2010608/files/fra_t_11_1_31.pdf"},"version_id":"b112d165-a84a-41d5-97f5-6d4853e83003"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"雨水; 栄養塩; 広島県; 瀬戸内海","subitem_subject_language":"ja","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":"journal article","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"広島県で採取された雨水中の栄養塩濃度について","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"広島県で採取された雨水中の栄養塩濃度について","subitem_title_language":"ja"},{"subitem_title":"Nutrient concentrations in precipitation collected in Hiroshima Prefecture","subitem_title_language":"en"}]},"item_type_id":"10001","owner":"10","path":["1723085690263"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2024-08-06"},"publish_date":"2024-08-06","publish_status":"0","recid":"2010608","relation_version_is_last":true,"title":["広島県で採取された雨水中の栄養塩濃度について"],"weko_creator_id":"10","weko_shared_id":-1},"updated":"2024-09-05T08:41:33.011535+00:00"}
