As a result, following features were revealed; 1) The sea water sampled by ferry boats was available to examine salinity, chlorophyll a, and phosphate-P in the sea. 2) In short period, change of salinity was well correlated with that of precipitation, but not with concentration of phosphate-P. It might be due to adhesion of nutrient salts to clay carried by land waters. 3) The concentration of chlorophyll a (standing crop of phytoplankton) increased immediately after March. At the early April, it reached 0. 13 μg/l in maximum. But this value was much smaller than that from other waters in spring. 4) In long period, the concentration of phosphate-P decreased gradually. But the increase in chlorophyll a did not pay decreased quantity of phosphate-P. It might be caused by grazing of zooplankton or scattering by water movements.","subitem_description_language":"en","subitem_description_type":"Abstract"},{"subitem_description":"1986年1~4月,フェリーボートから採取した佐渡海峡の海水を分析し,以下の知見を得た.1. 佐渡海峡の中央部であれば,フェリーボートの雑用海水からでも塩分,クロロフィル,栄養塩類の変動は充分,把握できることが確認できた. 2. 短期的にみれば,塩分の変動は降水量とよく対応していたが,燐酸態燐との対応はみられなかった.これは流入した河川水中の浮泥によって栄養塩類が吸着され,沈降したためと考えられる.3. 佐渡海峡におけるクロロフィルa(植物プランクトン)量は3月以降,急増し,増減を繰り返しながら4月上旬には最大 0.13μg/lに達した.しかし,この濃度は,他の海域から春季大増殖として報告された値よりも極めて低い値であった.4. 長期的にみれば,燐酸態燐濃度は漸減する傾向にあったが,これに比べてクロロフィル濃度の増加量は極めて小さかった,これに関しては,動物プランクトン等による植物ブランクトンの捕食,あるいは移流による拡散などが考えられる.","subitem_description_language":"ja","subitem_description_type":"Abstract"}]},"item_10002_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"日本海区水産研究所","subitem_publisher_language":"ja"},{"subitem_publisher":"Japan Sea Regional Fisheries Research Laboratory","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":"js_k_37_21_26","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/2010362006","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":"AN00186380","subitem_source_identifier_type":"NCID"}]},"item_10002_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"0021-4620","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":[{"creatorAffiliations":[{"affiliationNameIdentifiers":[],"affiliationNames":[{"affiliationName":"","affiliationNameLang":"ja"}]}],"creatorNames":[{"creatorName":"Nagata, Hiroshi","creatorNameLang":"en"},{"creatorName":"長田, 宏","creatorNameLang":"ja"},{"creatorName":"ナガタ, ヒロシ","creatorNameLang":"ja-Kana"}],"familyNames":[{"familyName":"Nagata","familyNameLang":"en"},{"familyName":"長田","familyNameLang":"ja"},{"familyName":"ナガタ","familyNameLang":"ja-Kana"}],"givenNames":[{"givenName":"Hiroshi","givenNameLang":"en"},{"givenName":"宏","givenNameLang":"ja"},{"givenName":"ヒロシ","givenNameLang":"ja-Kana"}],"nameIdentifiers":[{"nameIdentifier":"2028","nameIdentifierScheme":"WEKO"},{"nameIdentifier":"80371988","nameIdentifierScheme":"e-Rad","nameIdentifierURI":"https://kaken.nii.ac.jp/ja/search/?qm=80371988"}]},{"creatorAffiliations":[{"affiliationNames":[{"affiliationName":"日本海区水産研究所","affiliationNameLang":"ja"},{"affiliationName":"ニホンカイクスイサンケンキュウジョ","affiliationNameLang":"ja-Kana"},{"affiliationName":"Japan Sea Regional Fisheries Research Laboratory","affiliationNameLang":"en"}]}],"creatorNames":[{"creatorName":"木谷, 浩三","creatorNameLang":"ja"},{"creatorName":"キタニ, コウゾウ","creatorNameLang":"ja-Kana"},{"creatorName":"Kitani, Kozo","creatorNameLang":"en"}],"familyNames":[{"familyName":"木谷","familyNameLang":"ja"},{"familyName":"キタニ","familyNameLang":"ja-Kana"},{"familyName":"Kitani","familyNameLang":"en"}],"givenNames":[{"givenName":"浩三","givenNameLang":"ja"},{"givenName":"コウゾウ","givenNameLang":"ja-Kana"},{"givenName":"Kozo","givenNameLang":"en"}]}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"chlorophyll a; ferry boat; Japan Sea; nutrients; Sado Straits; spring bloom","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":"フェリーボートによる冬～春季の低次生産環境調査","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"フェリーボートによる冬～春季の低次生産環境調査","subitem_title_language":"ja"},{"subitem_title":"Investigation of Environmental Factors Concerning Primary Productivity in Winter to Spring by Ferry Boats","subitem_title_language":"en"}]},"item_type_id":"10002","owner":"10","path":["1716951426151"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2024-04-23"},"publish_date":"2024-04-23","publish_status":"0","recid":"2002508","relation_version_is_last":true,"title":["フェリーボートによる冬～春季の低次生産環境調査"],"weko_creator_id":"10","weko_shared_id":-1},"updated":"2025-04-01T04:27:57.150386+00:00"}
