There were two groups of sand dune lakes, Niigata sand dune lakes and Katamachi sand dune lakes. Lakes were characterized in the view of high and fluctuated water temperature, high pH values and comparatively low electric conductivity, whereas spring water had low water temperature, pH and dissolved oxygen concentration with small fluctuations. A water bloom by phytoplankton was observed in some lakes in Katamachi sand dune lakes. Origin and age of lakes were also discussed based on the formation age of sand dunes revealed by archaeological relics.", "subitem_description_type": "Abstract"}]}, "item_7_full_name_3": {"attribute_name": "著者別名", "attribute_value_mlt": [{"nameIdentifiers": [{"nameIdentifier": "156457", "nameIdentifierScheme": "WEKO"}], "names": [{"name": "Fukuhara, Haruo"}]}, {"nameIdentifiers": [{"nameIdentifier": "156458", "nameIdentifierScheme": "WEKO"}], "names": [{"name": "Kimura, Naoya"}]}, {"nameIdentifiers": [{"nameIdentifier": "156459", "nameIdentifierScheme": "WEKO"}], "names": [{"name": "Nemoto, Fumiko"}]}, {"nameIdentifiers": [{"nameIdentifier": "156460", "nameIdentifierScheme": "WEKO"}], "names": [{"name": "Toda, Hideshige"}]}, {"nameIdentifiers": [{"nameIdentifier": "156461", "nameIdentifierScheme": "WEKO"}], "names": [{"name": "Nohara, Seiichi"}]}, {"nameIdentifiers": [{"nameIdentifier": "156462", "nameIdentifierScheme": "WEKO"}], "names": [{"name": "Ohtaka, Akifumi"}]}]}, "item_7_publisher_7": {"attribute_name": "出版者", "attribute_value_mlt": [{"subitem_publisher": "新潟大学教育学部"}]}, "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": "AA12358288", "subitem_source_identifier_type": "NCID"}]}, "item_7_source_id_9": {"attribute_name": "ISSN", "attribute_value_mlt": [{"subitem_source_identifier": "13442961", "subitem_source_identifier_type": "ISSN"}]}, "item_creator": {"attribute_name": "著者", "attribute_type": "creator", "attribute_value_mlt": [{"creatorNames": [{"creatorName": "福原, 晴夫"}], "nameIdentifiers": [{"nameIdentifier": "156451", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "木村, 直哉"}], "nameIdentifiers": [{"nameIdentifier": "156452", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "根本, 富美子"}], "nameIdentifiers": [{"nameIdentifier": "156453", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "戸田, 任重"}], "nameIdentifiers": [{"nameIdentifier": "156454", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "野原, 精一"}], "nameIdentifiers": [{"nameIdentifier": "156455", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "大高, 明史"}], "nameIdentifiers": [{"nameIdentifier": "156456", "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": "2019-08-19"}], "displaytype": "detail", "download_preview_message": "", "file_order": 0, "filename": "1(1)_13-29.pdf", "filesize": [{"value": "2.2 MB"}], "format": "application/pdf", "future_date_message": "", "is_thumbnail": false, "licensetype": "license_free", "mimetype": "application/pdf", "size": 2200000.0, "url": {"label": "1(1)_13-29.pdf", "url": "https://niigata-u.repo.nii.ac.jp/record/26531/files/1(1)_13-29.pdf"}, "version_id": "096cd18b-e818-4338-b5ca-516d47cf716f"}]}, "item_keyword": {"attribute_name": "キーワード", "attribute_value_mlt": [{"subitem_subject": "砂丘湖", "subitem_subject_scheme": "Other"}, {"subitem_subject": "新潟砂丘湖沼群", "subitem_subject_scheme": "Other"}, {"subitem_subject": "潟町砂丘湖沼群", "subitem_subject_scheme": "Other"}, {"subitem_subject": "湧水", "subitem_subject_scheme": "Other"}, {"subitem_subject": "水質", "subitem_subject_scheme": "Other"}, {"subitem_subject": "クロロフィルa", "subitem_subject_scheme": "Other"}, {"subitem_subject": "富栄養化", "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": "departmental bulletin paper", "resourceuri": "http://purl.org/coar/resource_type/c_6501"}]}, "item_title": "新潟県における砂丘湖の現状", "item_titles": {"attribute_name": "タイトル", "attribute_value_mlt": [{"subitem_title": "新潟県における砂丘湖の現状"}, {"subitem_title": "新潟県における砂丘湖の現状", "subitem_title_language": "en"}]}, "item_type_id": "7", "owner": "1", "path": ["456", "1406"], "permalink_uri": "http://hdl.handle.net/10191/6689", "pubdate": {"attribute_name": "公開日", "attribute_value": "2008-11-13"}, "publish_date": "2008-11-13", "publish_status": "0", "recid": "26531", "relation": {}, "relation_version_is_last": true, "title": ["新潟県における砂丘湖の現状"], "weko_shared_id": null}
