The preliminary results reveal the locations of geological boundaries and shear zones/faults, which may indicate that VLF anomalies are due to shear zones or alteration zones located along contacts between different rock types. The strength of the VLF anomaly decreases over the polar ice cap. The inphase component of the VLF anomaly, when processed and interpreted with an analytic signal approach, yields a depth range of 15-30 m, whereas Fraser and Hjelt filter analyses yield a depth range of 25-60 m. The VLF-EM responses along all four traverses, along with their interpretations, are presented here as a case study.","subitem_description_type":"Abstract"}]},"item_10001_description_6":{"attribute_name":"内容記述","attribute_value_mlt":[{"subitem_description":"東南極Schirmacher（シルマッハ）地域でのVLF-EM法適用の可能性と実際の応答を知るため、４つの測線について測定を実施した。予察的な結果は、VLF異常が地質（岩相）境界、せん断断層の存在によって生じていることを示唆している。また、VLF異常の強さが氷帽によって減衰していることもわかった。VLF異常の同相（in-phase）成分を信号解析的な手法で解釈すると15-30 mの深さに原因があることがわかるが、FraserフィルターあるいはHjeltフィルター解析で解釈すると少し深い、25-60 m深度に原因があることがわかった。本文では、４測線すべてでの結果を事例研究として紹介している。","subitem_description_type":"Other"}]},"item_10001_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"国立極地研究所"}]},"item_10001_relation_12":{"attribute_name":"論文ID（NAID）","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"110008426645","subitem_relation_type_select":"NAID"}}]},"item_10001_relation_14":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_name":[{"subitem_relation_name_text":"10.1016/j.polar.2010.09.001"}],"subitem_relation_type_id":{"subitem_relation_type_id_text":"http://doi.org/10.1016/j.polar.2010.09.001","subitem_relation_type_select":"DOI"}}]},"item_10001_source_id_11":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AA12240481","subitem_source_identifier_type":"NCID"}]},"item_10001_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"18739652","subitem_source_identifier_type":"ISSN"}]},"item_access_right":{"attribute_name":"アクセス権","attribute_value_mlt":[{"subitem_access_right":"metadata only access","subitem_access_right_uri":"http://purl.org/coar/access_right/c_14cb"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"Gnaneshwar, P."}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Shivaji, A."}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Srinivas, Y."}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Jettaiah, P."}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Sundararajan, N."}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Gnaneshwar, P.","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Shivaji, A.","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Srinivas, Y.","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Jettaiah, P.","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Sundararajan, N.","creatorNameLang":"en"}],"nameIdentifiers":[{}]}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"Antarctica","subitem_subject_scheme":"Other"},{"subitem_subject":"VLF-EM method; Inphase","subitem_subject_scheme":"Other"},{"subitem_subject":"Out-of-phase","subitem_subject_scheme":"Other"},{"subitem_subject":"Fraser filtering","subitem_subject_scheme":"Other"},{"subitem_subject":"Antarctica","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"VLF-EM method; Inphase","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Out-of-phase","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Fraser filtering","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":"journal article","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"Very-low-frequency electromagnetic (VLF-EM) measurements in the Schirmacheroasen area, East Antarctica","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Very-low-frequency electromagnetic (VLF-EM) measurements in the Schirmacheroasen area, East Antarctica"},{"subitem_title":"Very-low-frequency electromagnetic (VLF-EM) measurements in the Schirmacheroasen area, East Antarctica","subitem_title_language":"en"}]},"item_type_id":"10001","owner":"17","path":["1350"],"pubdate":{"attribute_name":"公開日","attribute_value":"2014-10-16"},"publish_date":"2014-10-16","publish_status":"0","recid":"10209","relation_version_is_last":true,"title":["Very-low-frequency electromagnetic (VLF-EM) measurements in the Schirmacheroasen area, East Antarctica"],"weko_creator_id":"17","weko_shared_id":-1},"updated":"2023-07-25T16:20:52.252305+00:00"}
