Namazu Ike sediment core was mainly composed of algal(mainly cyanobacteria) and aquatic moss debris, whereas O-ike sediment core was comprised of coarse and fine sands with the influence of algal(mainly cyanobacteria) debris. The ages of core bottoms of Namazu Ike and O-ike were estimated to be 1550 and 2330 years before present(yBP), respectively. The sedimentation rates of Namazu Ike and O-ike were calculated to be 30 and 59 years/cm, respectively. Very high total organic carbon(TOC) contents(average 24.5%) of Namazu Ike revealed that the sediment core was mainly composed of organic matter. Dramatic increase of TOC/total nitrogen ratios at a depth of 25cm in Namazu Ike strongly suggests that aquatic moss increased from 1100yBP to the core top. Changes in n-alkanes, n-alkanoic and n-alkenoic acids, and sterol compositions in the O-ike sediment core, suggest that microbial composition changed considerably, but their source organisms are not clear and further studies are required.","subitem_description_type":"Other"}]},"item_1_identifier_registration":{"attribute_name":"ID登録","attribute_value_mlt":[{"subitem_identifier_reg_text":"10.15094/00006239","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":"AA11327019","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":"Department of Environmental Information Science, School of Social Information Studies, Otsuma Women's University/Department of Chemistry, Faculty of Science, Tokyo University of Science/Department of Environmental Information Science, School of Social Information Studies, Otsuma Women's University/National Institute of Polar Research/Department of Chemistry, Faculty of Science, Tokyo University of Science/National Institute of Polar Research/National Institute of Polar Research"}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2006-01-01"}],"displaytype":"detail","filename":"KJ00004015409.pdf","filesize":[{"value":"1.5 MB"}],"format":"application/pdf","licensetype":"license_6","mimetype":"application/pdf","url":{"label":"KJ00004015409","url":"https://nipr.repo.nii.ac.jp/record/6239/files/KJ00004015409.pdf"},"version_id":"038e4921-76a2-43dc-a3c9-47ff60299735"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"Antarctic lake","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"environmental change","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"sediment core","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"aquatic moss","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"organic components","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"carbon-14 AMS dating","subitem_subject_language":"en","subitem_subject_scheme":"Other"}]},"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":"Environmental changes in Syowa Station area of Antarctica during the last 2300 years inferred from organic components in lake sediment cores","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Environmental changes in Syowa Station area of Antarctica during the last 2300 years inferred from organic components in lake sediment cores"}]},"item_type_id":"1","owner":"4","path":["800"],"pubdate":{"attribute_name":"公開日","attribute_value":"2006-01-01"},"publish_date":"2006-01-01","publish_status":"0","recid":"6239","relation_version_is_last":true,"title":["Environmental changes in Syowa Station area of Antarctica during the last 2300 years inferred from organic components in lake sediment cores"],"weko_creator_id":"4","weko_shared_id":4},"updated":"2023-07-25T12:04:15.611558+00:00"}
