A single species of salp, Salpa thompsom, dominated others both numerically and by biomass, occupying 44% of mean total abundance with the maximum density of 29873 inds./l000m^3 (44 mg C/m^3). Abundance of Antarctic krill, Euphausia superba, was low through the sampling area (max. 41 inds./1000m^3: 2.9mg C/m^3). Total length frequency and stage of maturity of E. superba suggested relatively late spawning and low recruitment ratio, respectively. Salps and major copepod species showed a spatially partitioned pattern across the AD, in which the former dominated in areas north and south of the AD while the latter was predominant near the AD. Active reproduction of salps seemed to be ongoing in the areas where mean chl a concentration within the euphotic zone was around 0.4-0.6 μg/l, but suppressed where that was higher than 0.6 μg/l. Clogging of mucous nets of salps was considered to be one of the causes of their low abundance at high chl a concentration as observed near the AD. The results suggest that the relatively limited phytoplankton growth, particularly in the eastern side of this research area, may have provided the food condition which was optimal for salp reproduction but unfavorable for other phytoplankton consumers, permitting an explosive population growth of salps.","subitem_description_type":"Other"}]},"item_1_identifier_registration":{"attribute_name":"ID登録","attribute_value_mlt":[{"subitem_identifier_reg_text":"10.15094/00005362","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":"AA10819561","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":"Tokyo University of Fisheries"},{"subitem_text_language":"en","subitem_text_value":"Tokyo University of Fisheries"},{"subitem_text_language":"en","subitem_text_value":"Tokyo University of Fisheries"},{"subitem_text_language":"en","subitem_text_value":"Tokyo University of Fisheries"},{"subitem_text_language":"en","subitem_text_value":"Tokyo University of Fisheries"}]},"item_1_text_3":{"attribute_name":"記事種別(英)","attribute_value_mlt":[{"subitem_text_language":"en","subitem_text_value":"Proceeding"}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"1998-02-01"}],"displaytype":"detail","filename":"KJ00000767705.pdf","filesize":[{"value":"2.5 MB"}],"format":"application/pdf","licensetype":"license_6","mimetype":"application/pdf","url":{"label":"KJ00000767705","url":"https://nipr.repo.nii.ac.jp/record/5362/files/KJ00000767705.pdf"},"version_id":"c31cee45-cb42-4e85-b4c2-f252bc109349"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"macrozooplankton","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"distribution","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Antarctic Divergence","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Wilkes Land","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Salpa thompsom","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":"MACROZOOPLANKTON DISTRIBUTION AROUND THE ANTARCTIC DIVERGENCE OFF WILKES LAND IN THE 1996 AUSTRAL SUMMER : WITH REFERENCE TO HIGH ABUNDANCE OF SALPA THOMPSONI (19th Symposium on Polar Biology)","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"MACROZOOPLANKTON DISTRIBUTION AROUND THE ANTARCTIC DIVERGENCE OFF WILKES LAND IN THE 1996 AUSTRAL SUMMER : WITH REFERENCE TO HIGH ABUNDANCE OF SALPA THOMPSONI (19th Symposium on Polar Biology)"}]},"item_type_id":"1","owner":"4","path":["647"],"pubdate":{"attribute_name":"公開日","attribute_value":"1998-02-01"},"publish_date":"1998-02-01","publish_status":"0","recid":"5362","relation_version_is_last":true,"title":["MACROZOOPLANKTON DISTRIBUTION AROUND THE ANTARCTIC DIVERGENCE OFF WILKES LAND IN THE 1996 AUSTRAL SUMMER : WITH REFERENCE TO HIGH ABUNDANCE OF SALPA THOMPSONI (19th Symposium on Polar Biology)"],"weko_creator_id":"4","weko_shared_id":4},"updated":"2023-07-25T12:09:49.396148+00:00"}
