The δ^\u003c13\u003eC values of algae from Antarctica are relatively higher than global values. The reason for the relatively high δ^\u003c13\u003eC values of Antarctic algae may be sought in the limited CO_2 (aq) supply for algae in lake water. ^\u003c14\u003eC concentrations of algae from ponds in the First Crater and Crater Hill near McMurdo Station on Ross Island, where glacial meltwater does not flow into the ponds, are close to the global level in the same year. On the other hand, the algae from Richardson Lake in the Mt. Riiser-Larsen area in Enderby Land, where glacial meltwater flows into the lake, apparently have low ^\u003c14\u003eC concentration, ca. 90% of the global level. These facts lead us to the conclusion that the ^\u003c14\u003eC anomaly is attributable to a DIC of relatively low ^\u003c14\u003eC concentration derived from glacial meltwater with older carbon. If such samples are used for ^\u003c14\u003eC dating, the age determination will be erroneous.", "subitem_description_type": "Other"}]}, "item_1_identifier_registration": {"attribute_name": "ID登録", "attribute_value_mlt": [{"subitem_identifier_reg_text": "10.15094/00003056", "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": "AA1130866X", "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": "Earth and Planetary Sciences, Graduate School of Science, Nagoya University/Biology and Geoscience, Faculty of Science, Shizuoka University/Dating and Materials Research Center, Nagoya University/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": "1999-10-01"}], "displaytype": "detail", "download_preview_message": "", "file_order": 0, "filename": "KJ00000044173.pdf", "filesize": [{"value": "1.5 MB"}], "format": "application/pdf", "future_date_message": "", "is_thumbnail": false, "licensetype": "license_6", "mimetype": "application/pdf", "size": 1500000.0, "url": {"label": "KJ00000044173", "url": "https://nipr.repo.nii.ac.jp/record/3056/files/KJ00000044173.pdf"}, "version_id": "444a500b-2248-44de-ae0d-d4fa25aaa244"}]}, "item_keyword": {"attribute_name": "キーワード", "attribute_value_mlt": [{"subitem_subject": "AMS ^\u003c14\u003eC measurement", "subitem_subject_language": "en", "subitem_subject_scheme": "Other"}, {"subitem_subject": "Antarctic algae", "subitem_subject_language": "en", "subitem_subject_scheme": "Other"}, {"subitem_subject": "^\u003c14\u003eC anomaly", "subitem_subject_language": "en", "subitem_subject_scheme": "Other"}, {"subitem_subject": "reservoir effect", "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": "14C anomaly of freshwater algae in Antarctic coastal ponds and lakes", "item_titles": {"attribute_name": "タイトル", "attribute_value_mlt": [{"subitem_title": "14C anomaly of freshwater algae in Antarctic coastal ponds and lakes"}]}, "item_type_id": "1", "owner": "4", "path": ["437"], "permalink_uri": "https://doi.org/10.15094/00003056", "pubdate": {"attribute_name": "公開日", "attribute_value": "1999-10-01"}, "publish_date": "1999-10-01", "publish_status": "0", "recid": "3056", "relation": {}, "relation_version_is_last": true, "title": ["14C anomaly of freshwater algae in Antarctic coastal ponds and lakes"], "weko_shared_id": 4}
