During the summer of 1991/92, a large increase in the Chl a occurred under light sea ice conditions (2m) in mid January, and a lower increase under heavy sea ice conditions (2.5-2.7m). During the summer of 1996/97, a uniform increase in Chl a was observed, reaching a maximum in late January, although the sea ice thickness varied during this time (2.1-3.6m). In late December 1997, the first increase in Chl a occurred under a sea ice thickness of 2.2-2.6m. The Chl a decreased during the period from the 8^<th> to the 14^<th> of January and increased again after the 15^<th> of January. From mid December to mid January 1991/92, the northern fast ice limit was located at approximately 68°S. In the 1996/97 summer season, the northern fast ice limit was located at approximately 68°45'S at the end of December and the beginning of January. In mid December 1997, the northern limit was already located south of 69°S. The spatial relationships between the position of the ice edge, where the ice edge bloom occurs, and the survey area seem to result in the annual variation in Chl a near Syowa Station.","subitem_description_type":"Other"}]},"item_10001_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"日本海洋学会"}]},"item_10001_relation_12":{"attribute_name":"論文ID（NAID）","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"110007999339","subitem_relation_type_select":"NAID"}}]},"item_10001_source_id_11":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AN10492259","subitem_source_identifier_type":"NCID"}]},"item_10001_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"13422758","subitem_source_identifier_type":"ISSN"}]},"item_access_right":{"attribute_name":"アクセス権","attribute_value_mlt":[{"subitem_access_right":"metadata only access","subitem_access_right_uri":"http://purl.org/coar/access_right/c_14cb"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"小達, 恒夫"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Odate, Tsuneo","creatorNameLang":"en"}],"nameIdentifiers":[{}]}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"南極地域観測","subitem_subject_scheme":"Other"},{"subitem_subject":"リュツォ・ホルム湾","subitem_subject_scheme":"Other"},{"subitem_subject":"海氷変動","subitem_subject_scheme":"Other"},{"subitem_subject":"生態系変動","subitem_subject_scheme":"Other"}]},"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":"journal article","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"南極リュツォ・ホルム湾昭和基地周辺海域における海氷変動と生物過程の関係(シンポジウム:世界の沿岸海域における環境と生態系の長期変動)","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"南極リュツォ・ホルム湾昭和基地周辺海域における海氷変動と生物過程の関係(シンポジウム:世界の沿岸海域における環境と生態系の長期変動)"},{"subitem_title":"Relationship between Sea Ice Variation and Biological Processes near Syowa Station in Lutzow-Holm Bay, Antarctica(Symposium: International Symposium on Long-term Variations in the Coastal Environments and Ecosystems)","subitem_title_language":"en"}]},"item_type_id":"10001","owner":"18","path":["1404"],"pubdate":{"attribute_name":"公開日","attribute_value":"2015-08-21"},"publish_date":"2015-08-21","publish_status":"0","recid":"10874","relation_version_is_last":true,"title":["南極リュツォ・ホルム湾昭和基地周辺海域における海氷変動と生物過程の関係(シンポジウム:世界の沿岸海域における環境と生態系の長期変動)"],"weko_creator_id":"18","weko_shared_id":18},"updated":"2023-07-25T14:01:41.767868+00:00"}
