Diatoms of 243 species belonging to 53 genera are identified. The diatom floras in this core are divided into seven divisions, D-1 to D-7. The D-1 to D-6 are in the Holocene and the D-7 is in the Pleistocene. The D-7 is dominant in fresh water species. The D-6 is a mixed flora of marine and fresh water species. The D-5 is characterized by the abundant existence of Cyclotella caspia as an indicator of brackish lake with low salinity. The D-4 is characterized by the appearance of several kinds of planktonic species in marine, brackish and fresh water. The D-3 consists mainly of a fresh water lake species Aulacoseira granulate. The D-2 and D-1consist mainly of fresh water species such as Aulacoseira ambigua and Achnanthes spp..","subitem_description_type":"Abstract"}]},"item_7_publisher_7":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"新潟大学理学部"}]},"item_7_select_19":{"attribute_name":"著者版フラグ","attribute_value_mlt":[{"subitem_select_item":"publisher"}]},"item_7_source_id_11":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AA11436808","subitem_source_identifier_type":"NCID"}]},"item_7_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"13491237","subitem_source_identifier_type":"ISSN"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"Yasui, Satoshi"}],"nameIdentifiers":[{"nameIdentifier":"54511","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Kobayashi, Iwao"}],"nameIdentifiers":[{"nameIdentifier":"54512","nameIdentifierScheme":"WEKO"}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2019-08-06"}],"displaytype":"detail","filename":"16_47-81.pdf","filesize":[{"value":"31.0 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"16_47-81.pdf","url":"https://niigata-u.repo.nii.ac.jp/record/6874/files/16_47-81.pdf"},"version_id":"23fd2ca4-d564-4322-a078-04f0272b2683"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"Brackish lake","subitem_subject_scheme":"Other"},{"subitem_subject":"diatom","subitem_subject_scheme":"Other"},{"subitem_subject":"Echigo Plain","subitem_subject_scheme":"Other"},{"subitem_subject":"Pleistocene-Holocene","subitem_subject_scheme":"Other"},{"subitem_subject":"Shiotsugata Lagoon","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":"Pleistocene-Holocene diatom floras of the Shiotsugata Lagoon in the Echigo Plain, central Japan","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Pleistocene-Holocene diatom floras of the Shiotsugata Lagoon in the Echigo Plain, central Japan"},{"subitem_title":"Pleistocene-Holocene diatom floras of the Shiotsugata Lagoon in the Echigo Plain, central Japan","subitem_title_language":"en"}]},"item_type_id":"7","owner":"1","path":["456","198"],"pubdate":{"attribute_name":"公開日","attribute_value":"2017-08-31"},"publish_date":"2017-08-31","publish_status":"0","recid":"6874","relation_version_is_last":true,"title":["Pleistocene-Holocene diatom floras of the Shiotsugata Lagoon in the Echigo Plain, central Japan"],"weko_creator_id":"1","weko_shared_id":null},"updated":"2022-12-15T03:40:06.859461+00:00"}
