The CO_2 concentration and δ^<13>C observed in 1991-1999 showed clear seasonal cycles with peak-to-peak amplitudes of 16.5‰ ppmv and 0.8,respectively. From comparison of the seasonal cycles, it was found that the seasonal CO_2 cycle in Ny-Ålesund is mainly caused by seasonal change of biospheric activities. Interannual variations of the CO_2 concentration and δ^<13>C superimposed on their secular trends were also observed. Comparing both of the interannual variations revealed that the cause was primarily ascribed to the imbalance of the CO_2 exchange between the atmosphere and the terrestrial biosphere.","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":"National Institute of Polar Research"},{"subitem_text_language":"en","subitem_text_value":"National Institute of Polar Research"},{"subitem_text_language":"en","subitem_text_value":"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":"2001-03-01"}],"displaytype":"detail","filename":"KJ00000012913.pdf","filesize":[{"value":"982.3 kB"}],"format":"application/pdf","licensetype":"license_6","mimetype":"application/pdf","url":{"label":"KJ00000012913","url":"https://nipr.repo.nii.ac.jp/record/2361/files/KJ00000012913.pdf"},"version_id":"d944f3f8-0096-45a0-8f06-e4c691234c4f"}]},"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":"Temporal variations of atmospheric CO2 concentration and carborn isotope ratio in Ny-Alesund, Svalbard","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Temporal variations of atmospheric CO2 concentration and carborn isotope ratio in Ny-Alesund, Svalbard","subitem_title_language":"en"}]},"item_type_id":"1","owner":"4","path":["408"],"pubdate":{"attribute_name":"公開日","attribute_value":"2001-03-01"},"publish_date":"2001-03-01","publish_status":"0","recid":"2361","relation_version_is_last":true,"title":["Temporal variations of atmospheric CO2 concentration and carborn isotope ratio in Ny-Alesund, Svalbard"],"weko_creator_id":"4","weko_shared_id":4},"updated":"2023-07-25T13:39:22.951287+00:00"}
