Bathymetric charts of the areas near East Ongul Island and off the western part of the Prince Olav Coast were drawn, on the basis of sounding data of 980 points obtained by the author in 1974. The soundings were conducted with the echo-sounder which was developed in 1967 for the purpose of sounding from the surface of sea ice. Sampling of bottom sediments was attempted at 41 points in Lutzow-Holm Bay and near East Ongul Island, and 15 core samples of mud were obtained. The following are revealed by the examination of the charts: 1) Topographic trends near the Ongul Islands are in the north-south and east-west directions. They may be ascribed to glacial erosion which worked along the structural trend of foliations and joints of gneissic bedrock. 2) The fact that depressions and rises which, on the sea floor near the Ongul Islands, obviously extend north-south, suggests that the ice of this area in the past flowed from south to north. This direction of ice movement differs from the general east-west flow pattern of ice which is inferred from the glacial striae on the bedrock of East Ongul Island. These facts imply that the pattern of ice flow changed during fluctuation of the ice sheet. 3) The submarine topography near the Ongul Islands is discordant to the landform of the Ongul Islands, as the former shows large relief with steep slopes while the latter shows small relief within 40 meters in height. However, it remains unsolved whether or not the present sea level played a significant role in producing the contrast between subaerial and submarine topographies. 4) A narrow, long trough runs north-south from the northern corner of Liitzow-Holm Bay to off the western part of the Prince Olav Coast. This trough excavated the rise at a depth shallower than 200 meters. The longitudinal profile of the trough shows basin and sill topography apparently caused by glacial scouring. The trough is narrower than other troughs, and its north-south trend is discordant to the topographic trend of the adjacent areas. These features seem to indicate that the trough was moulded by selective erosion of glacial flow on a fracture zone in the bedrock. Existence of another trough nearby extending also north-south may prove that the glacier flowed from south to north. This direction of glacier movement, however, might differ to some extent from the general southeast-northwest flow pattern of ice sheet in this area. 5) Rather shallow troughs off outlet glaciers on the Prince Olav Coast are less conspicuous than the glacial troughs in Lutzow-Holm Bay. This fact seems to reflect the disparity in advance of the ice sheet of the two areas.","subitem_description_type":"Other"}]},"item_1_identifier_registration":{"attribute_name":"ID登録","attribute_value_mlt":[{"subitem_identifier_reg_text":"10.15094/00007838","subitem_identifier_reg_type":"JaLC"}]},"item_1_publisher_22":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"国立極地研究所"}]},"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":"551.4：551.77/.79","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":"Department of Geography, Faculty of Literature, Hiroshima University"}]},"item_1_text_2":{"attribute_name":"記事種別(日)","attribute_value_mlt":[{"subitem_text_value":"報告"}]},"item_1_text_3":{"attribute_name":"記事種別(英)","attribute_value_mlt":[{"subitem_text_language":"en","subitem_text_value":"Report"}]},"item_1_text_9":{"attribute_name":"著者所属(日)","attribute_value_mlt":[{"subitem_text_value":"広島大学文学部地理学教室"}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"1975-12-01"}],"displaytype":"detail","filename":"KJ00002476941.pdf","filesize":[{"value":"8.2 MB"}],"format":"application/pdf","licensetype":"license_6","mimetype":"application/pdf","url":{"label":"KJ00002476941","url":"https://nipr.repo.nii.ac.jp/record/7838/files/KJ00002476941.pdf"},"version_id":"381cba0c-70e1-4733-adc5-2fda5cf7f483"}]},"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":"昭和基地付近の海底地形 : 第15次越冬隊・地理部門報告1","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"昭和基地付近の海底地形 : 第15次越冬隊・地理部門報告1"},{"subitem_title":"Submarine Topography near Syowa Station, Antarctica","subitem_title_language":"en"}]},"item_type_id":"1","owner":"4","path":["960","1292"],"pubdate":{"attribute_name":"公開日","attribute_value":"1975-12-01"},"publish_date":"1975-12-01","publish_status":"0","recid":"7838","relation_version_is_last":true,"title":["昭和基地付近の海底地形 : 第15次越冬隊・地理部門報告1"],"weko_creator_id":"4","weko_shared_id":4},"updated":"2023-07-25T11:51:41.005034+00:00"}
