The study areas were in the Scotia Sea, in the South Georgia area (both on-shelf and off-shelf regions) and a large krill patch close to South Georgia. Comparison of the results from the three areas shows major differences in the diurnal patterns of vertical migration. Mean volume backscattering strength (MVBS) was analysed with respect to size of aggregations. The mean values for day and night were markedly different in the krill patch, the daytime value being higher than expected from concentration effects alone. In the other phases of the study, MVBS and concentration effects appeared to compensate and diurnal variation was less marked.","subitem_description_type":"Other"}]},"item_1_source_id_13":{"attribute_name":"雑誌書誌ID","attribute_value_mlt":[{"subitem_source_identifier":"AA00733561","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":"British Antarctic Survey, Natural Environment Research Council"}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"1983-07-01"}],"displaytype":"detail","filename":"KJ00000012070.pdf","filesize":[{"value":"1.1 MB"}],"format":"application/pdf","licensetype":"license_6","mimetype":"application/pdf","url":{"url":"https://nipr.repo.nii.ac.jp/record/1436/files/KJ00000012070.pdf"},"version_id":"1b5013ef-caed-4bf8-a3fd-c64875640ebb"}]},"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":"Variations in vertical distribution and density of krill swarms in the vicinity of South Georgia","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Variations in vertical distribution and density of krill swarms in the vicinity of South Georgia","subitem_title_language":"en"}]},"item_type_id":"1","owner":"4","path":["381"],"pubdate":{"attribute_name":"公開日","attribute_value":"1983-07-01"},"publish_date":"1983-07-01","publish_status":"0","recid":"1436","relation_version_is_last":true,"title":["Variations in vertical distribution and density of krill swarms in the vicinity of South Georgia"],"weko_creator_id":"4","weko_shared_id":4},"updated":"2023-07-25T13:53:49.878893+00:00"}
