Chlorophyll a was determined fluorometrically and primary productivity was measured by an in situ oxygen method. Horizontal distributions of the biomass showed relatively high production occurred near the coast of the cities of Hiroshima, Kure and Iwakuni where the influence of river runoff was strong. Phytoplankton biomass (mgChl. a· m -2) varied between 19.6 to 101.3 mgChl. a· m-2 with a maximum in June 1984. Two apparent blooms occurred in the bay. One a spring bloom began in February and the other a summer bloom occurred in June. The gross photosynthetic rate showed a maximum of 74.6 mgC.m-3·h-1 in August 1984. Mean assimilation number of the gross and net photosynthesis were 7.7 mgC.mgChl. a-1·h-1 and 6.1 mgC.mgChl. a-1·h-1, respectively. Temporal variations in the photosynthetic rate generally followed the seasonal cycle of the phytoplankton biomass. It appears that the nanoplankton (less than 10 μm) accounted for 47% of total chlorophyll a during the study period. The relative percentage of different size fractions did not show any marked seasonal cycle. A significant correlation was obtained between the photosynthetic rate and irradiance and chlorophyll a concentration. Dissolved nutrients exhibited marked seasonal variation, but were not correlated with the concurrent variations in phytoplankton photosynthetic rate.","subitem_description_language":"en","subitem_description_type":"Abstract"},{"subitem_description":"1984年2月から1985年7月の間,広島湾において植物プランクトン現存量と光合成速度を測定した。植物プランクトン現存量は19.6~101.3mgChl.a·m-2の範囲で大きく変動した。しかし,春季と6月付近に2つの現存量のピークが存在するなど,明瞭な季節変化がみられた。海域的には,河川水の影響の大きい湾奥部の広島市沖,呉市沖及び岩国沖で高い生産が行われていることが判明した。光合成速度は総光合成で 4.4~74.6mgC·m-3.h-1,純光合成で 3.4~66.1mgC·m-3.h-1の範囲にあり,そのビークは4~5月と7月にみられた。単位クロロフィルa当たりの光合成速度は,総光合成で平均(土標準偏差)7.7±3.5mgC·mgChl.a-1·h-1,純光合成で6.1±3.5mgC·mgChl.a-1·h-1であった。ナノプランクトン(10μm以下)のクロロフィルaが全体に占める割合は平均47%であり,ナノプランクトンの割合に明瞭な季節変化はみられなかった。光合成速度との間で有為な相関が得られた環境因子は,日射量(p<0.01)とクロロフィルa濃度(p<0.05)であった。栄養塩濃度は明瞭な季節変動を示したが,光合成速度との間に相関関係はみとめられなかった。","subitem_description_language":"ja","subitem_description_type":"Abstract"}]},"item_10002_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"南西海区水産研究所","subitem_publisher_language":"ja"},{"subitem_publisher":"Nansei National Fisheries Research Instituite","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":"nnf_k_28_63","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/2010510445","subitem_relation_type_select":"URI"}}]},"item_10002_source_id_11":{"attribute_name":"item_10002_source_id_11","attribute_value_mlt":[{"subitem_source_identifier":"AN00181988","subitem_source_identifier_type":"NCID"}]},"item_10002_source_id_9":{"attribute_name":"item_10002_source_id_9","attribute_value_mlt":[{"subitem_source_identifier":"0388-841X","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":[{"affiliationNames":[{"affiliationNameLang":"ja"}]}],"creatorNames":[{"creatorName":"Yamaguchi, Mineo","creatorNameLang":"en"},{"creatorName":"山口, 峰生","creatorNameLang":"ja"},{"creatorName":"ヤマグチ, ミネオ","creatorNameLang":"ja-Kana"}],"familyNames":[{"familyName":"Yamaguchi","familyNameLang":"en"},{"familyName":"山口","familyNameLang":"ja"},{"familyName":"ヤマグチ","familyNameLang":"ja-Kana"}],"givenNames":[{"givenName":"Mineo","givenNameLang":"en"},{"givenName":"峰生","givenNameLang":"ja"},{"givenName":"ミネオ","givenNameLang":"ja-Kana"}],"nameIdentifiers":[{"nameIdentifier":"1782","nameIdentifierScheme":"WEKO"},{"nameIdentifier":"00371956","nameIdentifierScheme":"e-Rad_Researcher","nameIdentifierURI":"https://kaken.nii.ac.jp/ja/search/?qm=00371956"}]},{"creatorAffiliations":[{"affiliationNames":[{"affiliationNameLang":"ja"}]}],"creatorNames":[{"creatorName":"Imai, Ichiro","creatorNameLang":"en"},{"creatorName":"今井, 一郎","creatorNameLang":"ja"},{"creatorName":"イマイ, イチロウ","creatorNameLang":"ja-Kana"}],"familyNames":[{"familyName":"Imai","familyNameLang":"en"},{"familyName":"今井","familyNameLang":"ja"},{"familyName":"イマイ","familyNameLang":"ja-Kana"}],"givenNames":[{"givenName":"Ichiro","givenNameLang":"en"},{"givenName":"一郎","givenNameLang":"ja"},{"givenName":"イチロウ","givenNameLang":"ja-Kana"}],"nameIdentifiers":[{"nameIdentifier":"3313","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Matsuo, Yutaka","creatorNameLang":"en","creatorNameType":"Personal"},{"creatorName":"松尾, 豊","creatorNameLang":"ja","creatorNameType":"Personal"},{"creatorName":"マツオ, ユタカ","creatorNameLang":"ja-Kana","creatorNameType":"Personal"}],"familyNames":[{"familyName":"Matsuo","familyNameLang":"en"},{"familyName":"松尾","familyNameLang":"ja"},{"familyName":"マツオ","familyNameLang":"ja-Kana"}],"givenNames":[{"givenName":"Yutaka","givenNameLang":"en"},{"givenName":"豊","givenNameLang":"ja"},{"givenName":"ユタカ","givenNameLang":"ja-Kana"}],"nameIdentifiers":[{"nameIdentifier":"3330","nameIdentifierScheme":"WEKO"}]}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"Hiroshima Bay;
