DM at the surfaces of 14 lakes ranged from the atmospheric equilibrium concentration (about 4 nmol L?1 for fresh water) to 385 nmol L?1. Relatively low DM of less than 50 nmol L?1 were observed at about 60% of the lakes. Many of the lakes (area fraction of 85%) were supersaturated and are thus sources of methane to the atmosphere. The exchange coefficient was calculated using wind speed data at Syowa Station. Area fraction frequency distributions with 4 surface DM ranges were applied to all lakes at Syowa Oasis (110 lakes: total lake area of 9 km2). Extrapolation to the whole Syowa Oasis gives an estimate of total emission of about 1 t-CH4 yr?1. This is the first estimation of methane flux from the surfaces of thawed lakes to the atmosphere in Antarctica. Since methane efflux of about 2 t-CH4 yr?1 from frozen bubbles in lake ice was estimated in our previous study, a total amount of 3 t-CH4 yr?1 would be released to the atmosphere from the lakes during the ice melting season (December ~ January) at Syowa Oasis.", "subitem_description_type": "Abstract"}]}, "item_3_publisher_212": {"attribute_name": "出版者", "attribute_value_mlt": [{"subitem_publisher": "American Geophysical Union (AGU)"}]}, "item_3_relation_191": {"attribute_name": "DOI", "attribute_value_mlt": [{"subitem_relation_type_id": {"subitem_relation_type_id_text": "http://doi.org/10.1029/2010JD013822", "subitem_relation_type_select": "DOI"}}]}, "item_3_select_195": {"attribute_name": "著者版フラグ", "attribute_value_mlt": [{"subitem_select_item": "author"}]}, "item_access_right": {"attribute_name": "アクセス権", "attribute_value_mlt": [{"subitem_access_right": "open access", "subitem_access_right_uri": "http://purl.org/coar/access_right/c_abf2"}]}, "item_creator": {"attribute_name": "著者", "attribute_type": "creator", "attribute_value_mlt": [{"creatorNames": [{"creatorName": "SASAKI, Masafumi", "creatorNameLang": "en"}], "nameIdentifiers": [{"nameIdentifier": "38638", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "ENDOH, Noboru", "creatorNameLang": "en"}], "nameIdentifiers": [{"nameIdentifier": "38639", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "IMURA, Satoshi", "creatorNameLang": "en"}], "nameIdentifiers": [{"nameIdentifier": "38640", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "KUDOH, Sakae", "creatorNameLang": "en"}], "nameIdentifiers": [{"nameIdentifier": "38641", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "YAMANOUCHI, Takashi", "creatorNameLang": "en"}], "nameIdentifiers": [{"nameIdentifier": "38642", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "MORIMOTO, Shinji", "creatorNameLang": "en"}], "nameIdentifiers": [{"nameIdentifier": "38643", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "HASHIDA, Gen", "creatorNameLang": "en"}], "nameIdentifiers": [{"nameIdentifier": "38644", "nameIdentifierScheme": "WEKO"}]}]}, "item_files": {"attribute_name": "ファイル情報", "attribute_type": "file", "attribute_value_mlt": [{"accessrole": "open_date", "date": [{"dateType": "Available", "dateValue": "2016-11-22"}], "displaytype": "detail", "download_preview_message": "", "file_order": 0, "filename": "JGR-#2+(KIT-R).pdf", "filesize": [{"value": "879.3 kB"}], "format": "application/pdf", "future_date_message": "", "is_thumbnail": false, "licensetype": "license_note", "mimetype": "application/pdf", "size": 879300.0, "url": {"label": "JGR-#2+(KIT-R).pdf", "url": "https://kitami-it.repo.nii.ac.jp/record/7558/files/JGR-#2+(KIT-R).pdf"}, "version_id": "c929c57c-7dce-4500-ab04-02498692b02f"}]}, "item_keyword": {"attribute_name": "キーワード", "attribute_value_mlt": [{"subitem_subject": "Air-lake exchange", "subitem_subject_scheme": "Other"}, {"subitem_subject": "Syowa Oasis", "subitem_subject_scheme": "Other"}, {"subitem_subject": "East Antarctica", "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": "journal article", "resourceuri": "http://purl.org/coar/resource_type/c_6501"}]}, "item_title": "Air-lake exchange of methane during the open water season in Syowa Oasis, East Antarctica", "item_titles": {"attribute_name": "タイトル", "attribute_value_mlt": [{"subitem_title": "Air-lake exchange of methane during the open water season in Syowa Oasis, East Antarctica", "subitem_title_language": "en"}]}, "item_type_id": "3", "owner": "1", "path": ["87"], "permalink_uri": "https://kitami-it.repo.nii.ac.jp/records/7558", "pubdate": {"attribute_name": "PubDate", "attribute_value": "2013-11-11"}, "publish_date": "2013-11-11", "publish_status": "0", "recid": "7558", "relation": {}, "relation_version_is_last": true, "title": ["Air-lake exchange of methane during the open water season in Syowa Oasis, East Antarctica"], "weko_shared_id": -1}
