The gravity measurements were conducted by LaCoste-Romberg gravity meter (G-515) at about 10km-intervals along the traverse routes. The start-and-end measurement point were the absolute gravity point (IAGBN) at Syowa Station. Along the upward route to Dome-F, the measurements were often interrupted by instrument fluctuation induced by the strong wind. The instrument was cooled down (possible occurrence of the tears) at least twice when the oversnow vehicle did not move and the electric supply was stopped. The gravity values along the traverse routes were determined considering the correction of drift rates and some tears. The gravity anomalies were calculated by making use of the data both of surface elevation from GPS positioning with some modification by atmospheric pressure and of the ice thickness from the radio-echo soundings. The obtained free-air gravity anomaly profiles correlate well with those of bedrock elevation. The continuous data of bedrock elevation beneath the Dome-F area, obtained by radio-echo soundings, revealed the basin-like topographic structure of the glacier beds surrounded by bedrocks at comparatively higher altitude, which is supported by free-air anomaly data.","subitem_description_type":"Other"}]},"item_1_identifier_registration":{"attribute_name":"ID登録","attribute_value_mlt":[{"subitem_identifier_reg_text":"10.15094/00008841","subitem_identifier_reg_type":"JaLC"}]},"item_1_source_id_13":{"attribute_name":"雑誌書誌ID","attribute_value_mlt":[{"subitem_source_identifier":"AN00181831","subitem_source_identifier_type":"NCID"}]},"item_1_source_id_20":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"00857289","subitem_source_identifier_type":"ISSN"}]},"item_1_subject_21":{"attribute_name":"国際十進分類法","attribute_value_mlt":[{"subitem_subject":"550.34:551.2","subitem_subject_scheme":"UDC"}]},"item_1_text_10":{"attribute_name":"著者所属(英)","attribute_value_mlt":[{"subitem_text_language":"en","subitem_text_value":"National Institute of Polar Research"},{"subitem_text_language":"en","subitem_text_value":"Disaster Prevention Research Institute"},{"subitem_text_language":"en","subitem_text_value":"Communications Research Laboratory"},{"subitem_text_language":"en","subitem_text_value":"Institute for Hydrospheric and Atmospheric Sciences, Nagoya University"}]},"item_1_text_9":{"attribute_name":"著者所属(日)","attribute_value_mlt":[{"subitem_text_value":"国立極地研究所"},{"subitem_text_value":"京都大学防災研究所"},{"subitem_text_value":"通信総合研究所"},{"subitem_text_value":"名古屋大学大気水圏科学研究所"}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"1994-03-01"}],"displaytype":"detail","filename":"KJ00000140150.pdf","filesize":[{"value":"432.6 kB"}],"format":"application/pdf","licensetype":"license_6","mimetype":"application/pdf","url":{"label":"KJ00000140150","url":"https://nipr.repo.nii.ac.jp/record/8841/files/KJ00000140150.pdf"},"version_id":"23ac12a4-35a1-46a6-8205-cc0c2c7bb11f"}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"jpn"}]},"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":"1992年に実施した東南極ド-ムF周辺部の重力測定","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"1992年に実施した東南極ド-ムF周辺部の重力測定"},{"subitem_title":"Gravity survey on the Mizuho Plateau, East Antarctica along the traverse routes to Dome-F from Syowa Station","subitem_title_language":"en"}]},"item_type_id":"1","owner":"4","path":["1107"],"pubdate":{"attribute_name":"公開日","attribute_value":"1994-03-01"},"publish_date":"1994-03-01","publish_status":"0","recid":"8841","relation_version_is_last":true,"title":["1992年に実施した東南極ド-ムF周辺部の重力測定"],"weko_creator_id":"4","weko_shared_id":4},"updated":"2023-07-25T13:10:14.805838+00:00"}
