ISMIP HEINO has been designed to study large-scale ice-sheet instabilities, similar to those of the Laurentide ice sheet which are likely the cause of Heinrich events, on a simplified geometry which consists of a flat square with 4000 km side length. This square contains an area which resembles Hudson Bay and Hudson Strait, on which rapid sediment sliding can occur. The ice sheet is built up over 200 ka by assuming a temporally constant glacial climate. For the standard set-up of ISMIP HEINO, we obtain an oscillatory behaviour of the ice sheet with a main period of approx. 7.5 ka. One cycle consists of a gradual growth phase, followed by a massive surge through \"Hudson Bay\" and \"Hudson Strait\" owing to rapid sediment sliding on a molten bed. The occurrence of internal oscillations is robust against moderate variations of the surface boundary conditions and the strength of the sediment sliding. These findings support the idea of a free oscillatory mechanism as the main cause for large-scale ice-sheet surges.","subitem_description_type":"Other"}]},"item_1_identifier_registration":{"attribute_name":"ID登録","attribute_value_mlt":[{"subitem_identifier_reg_text":"10.15094/00003000","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":"AA1129795X","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":"Institute of Low Temperature Science, Hokkaido University/Graduate School of Environmental Science, Hokkaido University/Potsdam Institute for Climate Impact Research"}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2006-11-01"}],"displaytype":"detail","filename":"KJ00004449452.pdf","filesize":[{"value":"1.2 MB"}],"format":"application/pdf","licensetype":"license_6","mimetype":"application/pdf","url":{"label":"KJ00004449452","url":"https://nipr.repo.nii.ac.jp/record/3000/files/KJ00004449452.pdf"},"version_id":"40cc3faf-82f3-41cc-b20a-f7079c70d262"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"ice sheet, Heinrich event, instability, surge, model intercomparison","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":"Simulation of large-scale ice-sheet surges: The ISMIP HEINO experiments","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Simulation of large-scale ice-sheet surges: The ISMIP HEINO experiments"}]},"item_type_id":"1","owner":"4","path":["434"],"pubdate":{"attribute_name":"公開日","attribute_value":"2006-11-01"},"publish_date":"2006-11-01","publish_status":"0","recid":"3000","relation_version_is_last":true,"title":["Simulation of large-scale ice-sheet surges: The ISMIP HEINO experiments"],"weko_creator_id":"4","weko_shared_id":4},"updated":"2023-07-25T12:39:30.781520+00:00"}
