One hundred sixty-one seismic stations were temporarily installed along a profile about 151 km long and seven large shots with about 700 kg of dynamite were fired. In addition, one shot with charge size of 20 kg was also arranged along the profile. The obtained seismic records show the clear onsets of the first arrivals at distances of less than 100 km from each large shot. In particular, seismic waves traveling through the ice sheet and dispersed surface waves were clearly observed. Some later reflection phases were also detected. The obtained first travel time data show that the ice sheet is a two-layered structure consisting of an upper layer with a P wave velocity of 2.7-2.9 km/s and a lower layer of 3.7-3.9 km/s. The thickness of the upper layer is estimated to be about 36-45 m. The apparent velocity in the basement rock just beneath the ice sheet is 6.1-6.2 km/s in the central and southern parts of the profile and almost 5.9 km/s in the northern part. This report describes basic outlines of the exploration and the obtained seismic data.","subitem_description_type":"Other"}]},"item_1_identifier_registration":{"attribute_name":"ID登録","attribute_value_mlt":[{"subitem_identifier_reg_text":"10.15094/00009256","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":"Department of Earth and Environmental Sciences, Faculty of Science, Kagoshima University/Department of Earth Sciences, Faculty of Education, Aichi University of Education/Shimabara Observatory, Institute of Seismology and Volcanology, Faculty of Sciences, Kyushu University/Institute of Seismology and Volcanology, Graduate School of Science, Hokkaido University/Hokkaido NOF Corporation Technology & Development Department/Hakusan Corporation R&D Dept./Department of Earth and Planetary Sciences, Graduate School of Sciences, Kyushu University/Department of Polar Science, The Graduate University for Advanced Studies/National Institute of Polar Research"}]},"item_1_text_9":{"attribute_name":"著者所属(日)","attribute_value_mlt":[{"subitem_text_value":"鹿児島大学理学部地球環境科学科/愛知教育大学教育学部地学教室/九州大学大学院理学研究院地震火山観測研究センター/北海道大学大学院理学研究科附属地震火山研究観測センター/北海道日本油脂株式会社技術開発部/白山工業株式会社開発部/九州大学大学院理学府地球惑星科学専攻/総合研究大学院大学極域科学専攻/国立極地研究所"}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2003-03-01"}],"displaytype":"detail","filename":"KJ00000139378.pdf","filesize":[{"value":"5.4 MB"}],"format":"application/pdf","licensetype":"license_6","mimetype":"application/pdf","url":{"label":"KJ00000139378","url":"https://nipr.repo.nii.ac.jp/record/9256/files/KJ00000139378.pdf"},"version_id":"1d324813-6b12-47db-b43e-a4d8a35ca310"}]},"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":"東南極みずほ高原における屈折法および広角反射法地震探査-観測概要(第43次夏隊報告)-","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"東南極みずほ高原における屈折法および広角反射法地震探査-観測概要(第43次夏隊報告)-"},{"subitem_title":"A seismic refraction and wide-angle reflection exploration in 2002 on the Mizuho Plateau, East Antarctica-Outline of observations (JARE-43)-","subitem_title_language":"en"}]},"item_type_id":"1","owner":"4","path":["1136","1320"],"pubdate":{"attribute_name":"公開日","attribute_value":"2003-03-01"},"publish_date":"2003-03-01","publish_status":"0","recid":"9256","relation_version_is_last":true,"title":["東南極みずほ高原における屈折法および広角反射法地震探査-観測概要(第43次夏隊報告)-"],"weko_creator_id":"4","weko_shared_id":4},"updated":"2023-07-25T14:21:36.446253+00:00"}
