The large standing stock of algae in the ice provides an ample food source for heterotrophic consumers. The sea ice habitat is characterised by low temperatures and correspondingly high salinities. During winter, temperatures as low as-15℃ and salinities as high as 177 psu were recorded in the brine channel system of the upper part of Antarctic sea ice. The tolerance of sympagic organisms to increased salinities is remarkable. Algae grow in salinities of up to 95 psu and also sea ice animals can survive, grow and partly reproduce under high salinities. The foraminifer Neogloboquadrina pachyderma was subjected to a variety of different salinities. Formation of new chambers occurs in salinities of up to 58 psu, specimens survive 82 psu for at least a week, and drastic changes in salinity are tolerated, e.g. direct transfer from 30 to 60 psu or from 60 to 40 psu. Chamber formation rates are slightly slower at higher salinities and the final size of specimens decreases with increasing salinity. Reproduction was never observed in salinities above 50 psu, which corroborates earlier results that N. pachyderma does not reproduce within the sea ice.","subitem_description_type":"Other"}]},"item_1_identifier_registration":{"attribute_name":"ID登録","attribute_value_mlt":[{"subitem_identifier_reg_text":"10.15094/00005306","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":"Institute for Polar Ecology, University of Kiel"}]},"item_1_text_3":{"attribute_name":"記事種別(英)","attribute_value_mlt":[{"subitem_text_language":"en","subitem_text_value":"Proceeding"}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"1996-02-01"}],"displaytype":"detail","filename":"KJ00000767649.pdf","filesize":[{"value":"620.0 kB"}],"format":"application/pdf","licensetype":"license_6","mimetype":"application/pdf","url":{"label":"KJ00000767649","url":"https://nipr.repo.nii.ac.jp/record/5306/files/KJ00000767649.pdf"},"version_id":"db5e8d3b-a6a2-4974-9eae-605b0248c188"}]},"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":"ON THE SALINITY TOLERANCE OF THE PLANKTONIC FORAMINIFER NEOGLOBOQUADRINA PACHYDERMA FROM ANTARCTIC SEA ICE (17th Symposium on Polar Biology)","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"ON THE SALINITY TOLERANCE OF THE PLANKTONIC FORAMINIFER NEOGLOBOQUADRINA PACHYDERMA FROM ANTARCTIC SEA ICE (17th Symposium on Polar Biology)"}]},"item_type_id":"1","owner":"4","path":["645"],"pubdate":{"attribute_name":"公開日","attribute_value":"1996-02-01"},"publish_date":"1996-02-01","publish_status":"0","recid":"5306","relation_version_is_last":true,"title":["ON THE SALINITY TOLERANCE OF THE PLANKTONIC FORAMINIFER NEOGLOBOQUADRINA PACHYDERMA FROM ANTARCTIC SEA ICE (17th Symposium on Polar Biology)"],"weko_creator_id":"4","weko_shared_id":4},"updated":"2023-07-25T12:10:42.065580+00:00"}
