The exploration was composed of seven large explosions and 161seismic stations distributed along the 151 km-long seismic line.The first arrival time data are analyzed by a refraction method.It is found that the ice sheet is composed of two layers:the upper layer with P wave velocity of 2.7-2.9 km/s has thickness of 35-45 m,and the lower layer with P wave velocity of 3.7-3.9 km/s continues to the bedrock.Lateral velocity variation in the upper-most crust is revealed:P wave velocity for the upper-most crust in the southern and central parts is 6.1-6.2 km/s and that in the northern part is5.9 km/s. This result implies that the geological boundary observed along the coast in the Lu tzow-Holm Bay and Prince Olav Coast regions possibly continues to the inland area.The S wave velocity is also obtained to be roughly 3.5km/s for the whole upper-most crust.Travel time analysis of two distinct reflection phases shows two horizontal reflecting planes located at 19 and 40km depth; the latter corresponds to the Moho discontinuity.","subitem_description_type":"Other"}]},"item_1_identifier_registration":{"attribute_name":"ID登録","attribute_value_mlt":[{"subitem_identifier_reg_text":"10.15094/00003118","subitem_identifier_reg_type":"JaLC"}]},"item_1_publisher_22":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"National Institute of Polar Research"}]},"item_1_source_id_13":{"attribute_name":"雑誌書誌ID","attribute_value_mlt":[{"subitem_source_identifier":"AA1130866X","subitem_source_identifier_type":"NCID"}]},"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/Institute of Seismology and Volcanology, Faculty of Sciences, Kyushu University/Institute of Seismology and Volcanology, Graduate School of Science,Hokkaido University/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_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2003-10-01"}],"displaytype":"detail","filename":"KJ00000044112.pdf","filesize":[{"value":"3.2 MB"}],"format":"application/pdf","licensetype":"license_6","mimetype":"application/pdf","url":{"label":"KJ00000044112","url":"https://nipr.repo.nii.ac.jp/record/3118/files/KJ00000044112.pdf"},"version_id":"8438b0e3-923c-481a-a517-03752063349b"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"velocity model,Antarctica,Mizuho Plateau,crust","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":"departmental bulletin paper","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"Seismic refraction and wide-angle reflection exploration by JARE-43 on Mizuho Plateau, East Antarctica","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Seismic refraction and wide-angle reflection exploration by JARE-43 on Mizuho Plateau, East Antarctica"}]},"item_type_id":"1","owner":"4","path":["441"],"pubdate":{"attribute_name":"公開日","attribute_value":"2003-10-01"},"publish_date":"2003-10-01","publish_status":"0","recid":"3118","relation_version_is_last":true,"title":["Seismic refraction and wide-angle reflection exploration by JARE-43 on Mizuho Plateau, East Antarctica"],"weko_creator_id":"4","weko_shared_id":4},"updated":"2023-07-25T12:34:50.048514+00:00"}
