This paper analyzes a 456 min time series of under-ice noise that was recorded at a depth of 29.9 m in the central Arctic Ocean when the area was approximately 89% ice cover, UTC time, on August 8th, 2017. When the air temperature was higher than the freezing point of the surface sea water, the under-ice noise levels increased. In particular, the noise levels at 80–240 Hz and 380–660 Hz had two broad peaks and increased by 5–15 dB, furthermore, there was a large number of transient signals in the noise data. When the air temperature decreased and was less than the freezing point of the surface sea water, the under-ice noise levels gradually decreased, the broad peaks of the under-ice noise levels gradually disappeared, and the transient signals also disappeared. At the above two frequency bands, the correlation coefficients between the air temperature and under-ice noise levels were generally above 0.5 and reached a maximum value of 0.81. These results suggest that the changes in the under-ice noise levels could be attributed to sea ice melting.","subitem_description_type":"Abstract"}]},"item_10001_relation_14":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_name":[{"subitem_relation_name_text":"10.1016/j.polar.2020.100528"}],"subitem_relation_type_id":{"subitem_relation_type_id_text":"https://doi.org/10.1016/j.polar.2020.100528","subitem_relation_type_select":"DOI"}}]},"item_10001_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"18739652","subitem_source_identifier_type":"ISSN"}]},"item_access_right":{"attribute_name":"アクセス権","attribute_value_mlt":[{"subitem_access_right":"metadata only access","subitem_access_right_uri":"http://purl.org/coar/access_right/c_14cb"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"Wen, Hongtao","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Yang, Yanming","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Ruan, Hailin","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Zhou, Hongtao","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Wang, Ning","creatorNameLang":"en"}],"nameIdentifiers":[{}]}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"Ice melting noise","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Bubble clouds","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Air temperature","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Summer","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Central arctic ocean","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":"journal article","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"Nearfield measurements of ice melting noise in the central Arctic Ocean in summer","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Nearfield measurements of ice melting noise in the central Arctic Ocean in summer"},{"subitem_title":"Nearfield measurements of ice melting noise in the central Arctic Ocean in summer","subitem_title_language":"en"}]},"item_type_id":"10001","owner":"26","path":["2014"],"pubdate":{"attribute_name":"公開日","attribute_value":"2020-06-24"},"publish_date":"2020-06-24","publish_status":"0","recid":"16019","relation_version_is_last":true,"title":["Nearfield measurements of ice melting noise in the central Arctic Ocean in summer"],"weko_creator_id":"26","weko_shared_id":-1},"updated":"2023-07-25T13:00:42.080605+00:00"}
