The diatom assemblage in the water column consisted of chain-forming planktonic species, in contrast to the under-ice assemblage dominated by pennate species reported from this site in the past; this dissimilarity suggests the presence of an unconsolidated platelet ice layer under the congelation ice, within which planktonic species can bloom. Among the dominant diatoms, Porosira pseudodenticulata and Pseudo-nitzschia cf. turgiduloides were dominant in the water column, and their water column stocks were higher than their mass sedimentation. These species apparently maintain their populations in the surface layer, as their production remains in the water column. In contrast, Fragilariopsis kerguelensis and Thalassiosira australis were scarce in the water column but rich in the flux, indicating active sinking and export of their production to the benthic ecosystem. This distinction in buoyancy control and sinking characteristics of the dominant diatoms on release from the fast ice influences the diatom species composition and carbon flow under the ice.","subitem_description_type":"Abstract"}]},"item_10001_description_6":{"attribute_name":"内容記述","attribute_value_mlt":[{"subitem_description":"海氷から離脱するアイスアルジーの行く末を調査すべく、2005/6年夏季に南極昭和基地近傍の定着氷域において深度別の珪藻類の現存量、種類組成と沈降フラックスを調べました。もっとも優占するPorosira pseudodenticulataとPseudo-nitzschia cf.turgiduloidesの現存量はそれらの沈降量よりも大きく、個体群を表層水中で維持しているようです。これに対しFragilariopsis kerguelensisとThalassiosira australisは表層水中にはほとんど存在せず沈降フラックス中に多量に存在することから、生産した物質を盛んに沈降させて海底の生態系へ移送していることを示唆しています。","subitem_description_type":"Other"}]},"item_10001_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"国立極地研究所"}]},"item_10001_relation_12":{"attribute_name":"論文ID（NAID）","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"110006650439","subitem_relation_type_select":"NAID"}}]},"item_10001_relation_14":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_name":[{"subitem_relation_name_text":"10.1016/j.polar.2008.01.001"}],"subitem_relation_type_id":{"subitem_relation_type_id_text":"http://doi.org/10.1016/j.polar.2008.01.001","subitem_relation_type_select":"DOI"}}]},"item_10001_source_id_11":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AA12240481","subitem_source_identifier_type":"NCID"}]},"item_10001_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"18739652","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":"Ichinomiya, Mutsuo"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Gomi, Yasushi"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Nakamachi, Miwa"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Honda, Masaki"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Fukuchi, Mitsuo"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Taniguchi, Akira"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Ichinomiya, Mutsuo","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Gomi, Yasushi","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Nakamachi, Miwa","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Honda, Masaki","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Fukuchi, Mitsuo","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Taniguchi, Akira","creatorNameLang":"en"}],"nameIdentifiers":[{}]}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"Diatom assemblage","subitem_subject_scheme":"Other"},{"subitem_subject":"Fast ice","subitem_subject_scheme":"Other"},{"subitem_subject":"Antarctica","subitem_subject_scheme":"Other"},{"subitem_subject":"Sinking characteristics","subitem_subject_scheme":"Other"},{"subitem_subject":"Diatom assemblage","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Fast ice","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Antarctica","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Sinking characteristics","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":"journal article","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"Temporal variations in the abundance and sinking flux of diatoms under fast ice in summer near Syowa Station, East Antarctica","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Temporal variations in the abundance and sinking flux of diatoms under fast ice in summer near Syowa Station, East Antarctica"},{"subitem_title":"Temporal variations in the abundance and sinking flux of diatoms under fast ice in summer near Syowa Station, East Antarctica","subitem_title_language":"en"}]},"item_type_id":"10001","owner":"17","path":["1362"],"pubdate":{"attribute_name":"公開日","attribute_value":"2014-10-15"},"publish_date":"2014-10-15","publish_status":"0","recid":"10076","relation_version_is_last":true,"title":["Temporal variations in the abundance and sinking flux of diatoms under fast ice in summer near Syowa Station, East Antarctica"],"weko_creator_id":"17","weko_shared_id":-1},"updated":"2023-07-25T16:19:48.980714+00:00"}
