The lowest δ^<15>N value of around -50‰ was found for the epibenthic algae collected from nitrate-rich saline ponds in the Labyrinth. In Lake Vanda, nitrate in its maximum layer (57-59m) was significantly rich in ^<15>N (10.3-13.4‰) as compared with the sedimentary organic nitrogen (-4.6‰). The variation of δ^<15>N seemed to probably result from nitrogen isotope fractionation associated with nitrate assimilation by algae. In the east lobe of Lake Bonney, the δ^<15>N value in nitrate increased with depth from 4.9 to 31.2‰. Dissolved N_2 gas in the west lobe exhibited the highest δ^<15>N value (1.5-2.5‰) among those observed in anoxic layers of various aquatic systems. The latter results from denitrification of nitrate with high δ^<15>N value at temperatures lower than 0℃.","subitem_description_type":"Other"}]},"item_1_source_id_13":{"attribute_name":"雑誌書誌ID","attribute_value_mlt":[{"subitem_source_identifier":"AA00733561","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":"Mitsubishi-Kasei Institute of Life Sciences/Mitsubishi-Kasei Institute of Life Sciences/Department of Earth Sciences, Hirosaki University/Chiba Institute of Technology"}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"1984-08-01"}],"displaytype":"detail","filename":"KJ00000012256.pdf","filesize":[{"value":"1.7 MB"}],"format":"application/pdf","licensetype":"license_6","mimetype":"application/pdf","url":{"label":"KJ00000012256","url":"https://nipr.repo.nii.ac.jp/record/1623/files/KJ00000012256.pdf"},"version_id":"02eaf58d-a09e-43d6-80b4-e9f2dab1604d"}]},"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":"15N abundance in the Dry Valley area, south Victoria Land, Antarctica: Eco-physiological implications of microorganisms","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"15N abundance in the Dry Valley area, south Victoria Land, Antarctica: Eco-physiological implications of microorganisms","subitem_title_language":"en"}]},"item_type_id":"1","owner":"4","path":["386"],"pubdate":{"attribute_name":"公開日","attribute_value":"1984-08-01"},"publish_date":"1984-08-01","publish_status":"0","recid":"1623","relation_version_is_last":true,"title":["15N abundance in the Dry Valley area, south Victoria Land, Antarctica: Eco-physiological implications of microorganisms"],"weko_creator_id":"4","weko_shared_id":4},"updated":"2023-07-25T13:54:05.838094+00:00"}
