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 > 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 > 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 & 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"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2023-03-30"},"publish_date":"2023-03-30","publish_status":"0","recid":"5313","relation_version_is_last":true,"title":["A firn densification process in the high accumulation dome of southeastern Greenland"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-03-31T02:23:00.638658+00:00"}
