The total length of survey lines amounts to about 2100km along which various observations were made. This report, Parts 1 through 4 of this issue, describes mainly the results of the DELP-86 cruises. Some of the studies on the seismic structure are being continued by the Earthquake Prediction Research Program of Japan. Data and interpretations obtained by others related to the present program are also referred to in the interpretation of the present report (Part 1). Scientists from nine universities and institutions participated in the present study. The scientific objectives, survey area, cruise periods, items of observation, filing of data bases and names of participants in this program are listed in this Part 1. A series of basic data from seismic experiments on the present cruises are presented as a supplement for convenience in further studies. Some results obtained prior to the present survey are also included in the concluding remarks of this part. A configuration of the subducting Pacific Plate underneath Northeast Japan which was traced by using arrivals of sound signal data obtained by the onshore seismic observation network is also mentioned. Further detailed descriptions of individual experiments are given in Parts 2, 3 and 4 of this issue.","subitem_description_type":"Abstract"},{"subitem_description":"1986年夏季(7月から8月初旬)にDELP並びに地震予知海底観測両研究グループの協同作業によって,北西太平洋海盆のシャツキー海台と日本北部地域との間の海域に於て地球物理探査航海(DELP-86)が実施された.本報告のPart 1からPart 4にかけて,全長2100kmに及ぶ十字測線で行われた各種計測・探査につき, DELP-86航海の成果として報告する.地震音波構造解析の一部は,現在地震予知海底観測研究グループによって継続されている部分も有り,時間的制約から,全てを記述することはできなかった.また各Partの結果の説明等には,既に他の研究者などによって発表されているものをも引用している.今航海には大学・研究所等9機関からの研究者が参加した.本航海の主目的,探査海域,探査期間,探査項目,データ内容及び参加者等に付いて,本文に記載する.航海によって得られた人工地震探査の基礎的データを,今後の解析の便宜に供するために提示した.以上のような点について研究航海の報告を本稿で述べるが,結論・推論については過去の研究などで既に判明していることも含めて議論を行う.なお今回の人工地震観測用大発破音源から東北地方に伝播した人工地震波を利用して,東北日本孤下へ潜り込みつつある太平洋プレートの形状を追認できたことは,他所に既に報告されたが,本稿に合わせ紹介する.その他各分野の細かい研究成果に付いては, Part2, 3および4に詳しく述べられている.","subitem_description_type":"Abstract"}]},"item_4_full_name_3":{"attribute_name":"著者別名","attribute_value_mlt":[{"nameIdentifiers":[{"nameIdentifier":"127494","nameIdentifierScheme":"WEKO"}],"names":[{"name":"DELP大洋底深部構造研究班"}]}]},"item_4_identifier_registration":{"attribute_name":"ID登録","attribute_value_mlt":[{"subitem_identifier_reg_text":"10.15083/0000032781","subitem_identifier_reg_type":"JaLC"}]},"item_4_publisher_20":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"東京大学地震研究所"}]},"item_4_source_id_10":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AN00162258","subitem_source_identifier_type":"NCID"}]},"item_4_source_id_8":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"00408972","subitem_source_identifier_type":"ISSN"}]},"item_4_subject_15":{"attribute_name":"日本十進分類法","attribute_value_mlt":[{"subitem_subject":"453","subitem_subject_scheme":"NDC"}]},"item_4_text_21":{"attribute_name":"出版者別名","attribute_value_mlt":[{"subitem_text_value":"Earthquake Research Institute, University of Tokyo"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"Japanese DELP Research Group On Deep Structure Of Oceanic Lithosphere"}],"nameIdentifiers":[{"nameIdentifier":"127493","nameIdentifierScheme":"WEKO"}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2017-06-26"}],"displaytype":"detail","filename":"ji0651003.pdf","filesize":[{"value":"2.8 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"ji0651003.pdf","url":"https://repository.dl.itc.u-tokyo.ac.jp/record/32781/files/ji0651003.pdf"},"version_id":"c88e2cbf-8082-4f91-bf0a-70ba0a457b9e"}]},"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":"Report on DELP 1986 Cruises in the Northwestern Pacific : Part 1: General Outline","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Report on DELP 1986 Cruises in the Northwestern Pacific : Part 1: General Outline","subitem_title_language":"en"}]},"item_type_id":"4","owner":"1","path":["4735","4736"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2009-10-13"},"publish_date":"2009-10-13","publish_status":"0","recid":"32781","relation_version_is_last":true,"title":["Report on DELP 1986 Cruises in the Northwestern Pacific : Part 1: General Outline"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2022-12-19T05:17:26.698972+00:00"}
