The ice was-20.9 degrees C at 20 m depth, and the core gives an average accumulation rate of 1.0 m w.e. yr(-1) in water equivalent. However, the close-off density of 830 kg m(-3) occurs at 83.4-86.8 m depth, which is about 20-m shallower than that obtained from two empirical models. Where the density p \u0026gt; 750 kg m(-3), the densification appears faster than that from the empirical models. As a result, compared to the empirical coefficient, the actual compactive viscosity coefficient is nonlinear and decreases at p \u0026gt; 750 kg m(-3), indicating that the fun with a higher density is softer than that from the empirical result. We argue here that the high accumulation rate creates a high overburden pressure in a short time. Thus, the relative softness of the firn may arise from (1) there being not enough time to form bonds between grains as strong as those in a lower accumulation-rate area, and similarly, (2) the dislocation density in the firn being relatively high.", "subitem_description_language": "en", "subitem_description_type": "Other"}]}, "item_10001_publisher_8": {"attribute_name": "出版者", "attribute_value_mlt": [{"subitem_publisher": "TAYLOR \u0026 FRANCIS LTD", "subitem_publisher_language": "en"}]}, "item_10001_relation_14": {"attribute_name": "DOI", "attribute_value_mlt": [{"subitem_relation_type_id": {"subitem_relation_type_id_text": "10.1657/AAAR0016-034"}}]}, "item_10001_source_id_9": {"attribute_name": "ISSN", "attribute_value_mlt": [{"subitem_source_identifier": "1938-4246", "subitem_source_identifier_type": "EISSN"}]}, "item_creator": {"attribute_name": "著者", "attribute_type": "creator", "attribute_value_mlt": [{"creatorNames": [{"creatorName": "Yoshinori Iizuka", "creatorNameLang": "en"}]}, {"creatorNames": [{"creatorName": "Atsushi Miyamoto", "creatorNameLang": "en"}]}, {"creatorNames": [{"creatorName": "Akira Hori", "creatorNameLang": "en"}]}, {"creatorNames": [{"creatorName": "Sumito Matoba", "creatorNameLang": "en"}]}, {"creatorNames": [{"creatorName": "Ryoto Furukawa", "creatorNameLang": "en"}]}, {"creatorNames": [{"creatorName": "Takeshi Saito", "creatorNameLang": "en"}]}, {"creatorNames": [{"creatorName": "Shuji Fujita", "creatorNameLang": "en"}]}, {"creatorNames": [{"creatorName": "Motohiro Hirabayashi", "creatorNameLang": "en"}]}, {"creatorNames": [{"creatorName": "Satoru Yamaguchi", "creatorNameLang": "en"}]}, {"creatorNames": [{"creatorName": "Koji Fujita", "creatorNameLang": "en"}]}, {"creatorNames": [{"creatorName": "Nozomu Takeuchi", "creatorNameLang": "en"}]}]}, "item_language": {"attribute_name": "言語", "attribute_value_mlt": [{"subitem_language": "eng"}]}, "item_title": "A firn densification process in the high accumulation dome of southeastern Greenland", "item_titles": {"attribute_name": "タイトル", "attribute_value_mlt": [{"subitem_title": "A firn densification process in the high accumulation dome of southeastern Greenland", "subitem_title_language": "en"}]}, "item_type_id": "40001", "owner": "1", "path": ["1670839190650"], "permalink_uri": "https://nied-repo.bosai.go.jp/records/5313", "pubdate": {"attribute_name": "PubDate", "attribute_value": "2023-03-30"}, "publish_date": "2023-03-30", "publish_status": "0", "recid": "5313", "relation": {}, "relation_version_is_last": true, "title": ["A firn densification process in the high accumulation dome of southeastern Greenland"], "weko_shared_id": -1}
