Analysis was mainly done for sea ice in Lutzow-Holm Bay, ice streams flowing into the bay, ice sheet near the coast and inland nunataks. Back scattering coefficient of the SAR images differs clearly between first-year and multi-year sea ice covered with snow which are difficult to be distinguished in the MOS-1/MESSR images. Weak scattering is confirmed in bare sea ice because of the smooth surface and appears in summer comparing with that in winter. The back scattering differs clearly place to place in ice sheet weak in bear ice along the coast very week in the smooth dry snow area and scattered near nunataks.","subitem_description_type":"Other"}]},"item_1_identifier_registration":{"attribute_name":"ID登録","attribute_value_mlt":[{"subitem_identifier_reg_text":"10.15094/00008902","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":"551.32","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":"Communications Research Laboratory, Ministry of Posts and Telecommunications"},{"subitem_text_language":"en","subitem_text_value":"National Institute of Polar Research"},{"subitem_text_language":"en","subitem_text_value":"Tokai University Research & Information Center"},{"subitem_text_language":"en","subitem_text_value":"Hokkaido University of Education"},{"subitem_text_language":"en","subitem_text_value":"National Institute of Polar Research"},{"subitem_text_language":"en","subitem_text_value":"National Institute of Polar Research"}]},"item_1_text_2":{"attribute_name":"記事種別(日)","attribute_value_mlt":[{"subitem_text_value":"研究論文"}]},"item_1_text_3":{"attribute_name":"記事種別(英)","attribute_value_mlt":[{"subitem_text_language":"en","subitem_text_value":"Scientific Paper"}]},"item_1_text_9":{"attribute_name":"著者所属(日)","attribute_value_mlt":[{"subitem_text_value":"通信総合研究所"},{"subitem_text_value":"国立極地研究所"},{"subitem_text_value":"東海大学情報技術センター"},{"subitem_text_value":"北海道教育大学釧路校"},{"subitem_text_value":"国立極地研究所"},{"subitem_text_value":"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":"1995-11-01"}],"displaytype":"detail","filename":"KJ00002478258.pdf","filesize":[{"value":"1.5 MB"}],"format":"application/pdf","licensetype":"license_6","mimetype":"application/pdf","url":{"label":"KJ00002478258","url":"https://nipr.repo.nii.ac.jp/record/8902/files/KJ00002478258.pdf"},"version_id":"08d0170b-ea8e-40d2-8660-e8c9a2fd467f"}]},"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":"南極域における合成開口レーダー (SAR) 画像の雪氷研究への応用","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"南極域における合成開口レーダー (SAR) 画像の雪氷研究への応用"},{"subitem_title":"Application of Synthetic Aperture Radar (SAR) Imagery on Antarctic Glaciology","subitem_title_language":"en"}]},"item_type_id":"1","owner":"4","path":["1112"],"pubdate":{"attribute_name":"公開日","attribute_value":"1995-11-01"},"publish_date":"1995-11-01","publish_status":"0","recid":"8902","relation_version_is_last":true,"title":["南極域における合成開口レーダー (SAR) 画像の雪氷研究への応用"],"weko_creator_id":"4","weko_shared_id":4},"updated":"2023-07-25T13:11:52.780825+00:00"}
