Water temperature and salinity ranged from -1.1 to -1.4℃ and from 32.4 to 33.5, respectively. The maximum chlorophyll a concentrations of ice algae within 4cm from the bottom of sea ice and phytoplankton in water column were 385 and 0.77 mg m^<-3>, respectively. The maximum photosynthetic rate (1.12 mgO_2 mgchl, a^<-1> h^<-1>) of ice algae was obtained under 37.5 μEm^2 s^<-1>, which corresponds to only 3% of incident solar radiation. These results demonstrate the low-light adaptation of ice algae grown under low light conditions. The optimum temperature for photosynthesis of ice algae was around 8℃. In situ measurements on a clear day gave the primary production of 1.59 mgCm^<-2> h^<-1> by ice algae and that of 1.92 mgCm^<-2> h^<-1> by phytoplankton. It was concluded that the ice algae contribute to a considerable extent to the production of organic carbon in the ice-covered area of Saroma Ko during winter.","subitem_description_type":"Other"}]},"item_1_identifier_registration":{"attribute_name":"ID登録","attribute_value_mlt":[{"subitem_identifier_reg_text":"10.15094/00005043","subitem_identifier_reg_type":"JaLC"}]},"item_1_publisher_22":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"National Institute of Polar Research"}]},"item_1_source_id_13":{"attribute_name":"雑誌書誌ID","attribute_value_mlt":[{"subitem_source_identifier":"AA10819561","subitem_source_identifier_type":"NCID"}]},"item_1_text_10":{"attribute_name":"著者所属(英)","attribute_value_mlt":[{"subitem_text_language":"en","subitem_text_value":"Tokyo University of Fisheries/Laboratory of Biology, College of Liberal Arts, Saitama University/National Institute of Polar Research/National Institute of Polar Research/National Institute of Polar Research/Tokyo University of Fisheries"}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"1989-09-01"}],"displaytype":"detail","filename":"KJ00000036811.pdf","filesize":[{"value":"1.3 MB"}],"format":"application/pdf","licensetype":"license_6","mimetype":"application/pdf","url":{"label":"KJ00000036811","url":"https://nipr.repo.nii.ac.jp/record/5043/files/KJ00000036811.pdf"},"version_id":"764b2efc-4d77-4bc8-90ae-401c7e19be26"}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"eng"}]},"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":"Photosynthetic nature of ice algae and their contribution to the primary production in lagoon Saroma Ko, Hokkaido, Japan","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Photosynthetic nature of ice algae and their contribution to the primary production in lagoon Saroma Ko, Hokkaido, Japan"}]},"item_type_id":"1","owner":"4","path":["638"],"pubdate":{"attribute_name":"公開日","attribute_value":"1989-09-01"},"publish_date":"1989-09-01","publish_status":"0","recid":"5043","relation_version_is_last":true,"title":["Photosynthetic nature of ice algae and their contribution to the primary production in lagoon Saroma Ko, Hokkaido, Japan"],"weko_creator_id":"4","weko_shared_id":4},"updated":"2023-07-25T12:14:58.853356+00:00"}
