The survey includes the abyssal basin and the continental rise area of the Cooperation Sea (CS) and Prydz Bay (PB), offshore of Mac Robertson Land and Princess Elizabeth Land, Antarctica. In the northern abyssal plain of the CS, a mantle-like sequence (G) appears at a depth of 10 s two-way travel time (TWT), or approximately 13 km. The sequence disappears south of 64°S, in the southern part of the CS. These observations suggest that the southern part of the CS and PB is underlain by intermediate type crust that is characteristic of oceanic and continental material. The deep structure of most of the PB continental shelf is not clear due to strong seafloor multiples. More than 7 km of thick sedimentary sequences in the northwest area of PB are confirmed by the MCS survey. Very thick sedimentary sequences, interpreted as prerift, rift and drift sediment can be observed under thick pelagic sediment. Geological samples, which were recovered in the CS and PB, offer important evidence on the recent history of drift sediments caused by iceberg floes. Two cores reached 0.78 Ma (Bruhnes-Matsuyama (B-M) boundary) in magneto-stratigraphic measurements, and they gave distinct age determinations for recent sediments.","subitem_description_type":"Other"}]},"item_1_identifier_registration":{"attribute_name":"ID登録","attribute_value_mlt":[{"subitem_identifier_reg_text":"10.15094/00003098","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":"Technology Research Center, Japan National Oil Corporation/Geological Survey of Japan/Geological Survey of Japan/Geological Survey of Japan/Technology Research Center, Japan National Oil Corporation/Technology Research Center, Japan National Oil Corporation/Geological Survey of Japan/School of Geosciences, Division of Geology and Geophysics, Building F05, The University of Sydney"}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2001-10-01"}],"displaytype":"detail","filename":"KJ00000044216.pdf","filesize":[{"value":"3.1 MB"}],"format":"application/pdf","licensetype":"license_6","mimetype":"application/pdf","url":{"label":"KJ00000044216","url":"https://nipr.repo.nii.ac.jp/record/3098/files/KJ00000044216.pdf"},"version_id":"791e6707-e712-4bfe-9161-d939a6d2bf37"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"Cooperation Sea","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Prydz Bay","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Amery Ice Shelf","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"marine geological and geophysical surveys","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"sedimentary sequences","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"drift sediment","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"deep crustal structure","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":"departmental bulletin paper","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"Preliminary results of the TH99 geological and geophysical survey in the Cooperation Sea and Prydz Bay area","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Preliminary results of the TH99 geological and geophysical survey in the Cooperation Sea and Prydz Bay area"}]},"item_type_id":"1","owner":"4","path":["439"],"pubdate":{"attribute_name":"公開日","attribute_value":"2001-10-01"},"publish_date":"2001-10-01","publish_status":"0","recid":"3098","relation_version_is_last":true,"title":["Preliminary results of the TH99 geological and geophysical survey in the Cooperation Sea and Prydz Bay area"],"weko_creator_id":"4","weko_shared_id":4},"updated":"2023-07-25T12:34:59.561753+00:00"}
