Fossil diatom assemblages in the core as well as sedimentary properties were useful for examining historical changes of Holocene\u3000sedimentary environment and relative sea level. Based on ecological\u3000groups, diatoms of this site are\u3000classified into 14 ecological groups. They are marine planktonic, marine epiphytic, brackish planktonic, marine/brackish epipsammic, marine/brackish epipelic, marine/brackish aerophilous, marine/\u3000brackish epiphytic, brackish/fresh tychoplanktonic, brackish/fresh epiphytic, brackish/fresh planktonic, brackish/fresh aerophilous, fresh water epiphytic, fresh water planktonic and fresh water epipelic\u3000diatom groups.\u3000The stratigraphical change of these groups is divided into seven diatom divisions. Each diatom division is closely related to the evolution of sedimentation caused by Holocene sea level and geomorphological changes. In the Late Pleistocene, fluvial sediments were deposited in the site, then overlain by estuary sediments at the beginning of the Holocene transgression. Following the maximum Holocene transgression in 5,000 yr.BP, two small regressions occurred alternatively with two small transgressions respectively. After 1,800 yr.BP. fresh/brackish lacustrine sediments were deposited and marine/brackish lagoonal sediments have been deposited again since 1902 due to the construction of an artificial water way.", "subitem_description_type": "Abstract"}]}, "item_7_publisher_7": {"attribute_name": "\u51fa\u7248\u8005", "attribute_value_mlt": [{"subitem_publisher": "\u65b0\u6f5f\u5927\u5b66\u7406\u5b66\u90e8"}]}, "item_7_select_19": {"attribute_name": "\u8457\u8005\u7248\u30d5\u30e9\u30b0", "attribute_value_mlt": [{"subitem_select_item": "publisher"}]}, "item_7_source_id_11": {"attribute_name": "\u66f8\u8a8c\u30ec\u30b3\u30fc\u30c9ID", "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": "\u8457\u8005", "attribute_type": "creator", "attribute_value_mlt": [{"creatorNames": [{"creatorName": "Nguyen, Van Lap"}], "nameIdentifiers": [{"nameIdentifier": "54573", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "Kobayashi, Iwao"}], "nameIdentifiers": [{"nameIdentifier": "54574", "nameIdentifierScheme": "WEKO"}]}]}, "item_files": {"attribute_name": "\u30d5\u30a1\u30a4\u30eb\u60c5\u5831", "attribute_type": "file", "attribute_value_mlt": [{"accessrole": "open_date", "date": [{"dateType": "Available", "dateValue": "2019-08-06"}], "displaytype": "detail", "download_preview_message": "", "file_order": 0, "filename": "12_51-83.pdf", "filesize": [{"value": "11.1 MB"}], "format": "application/pdf", "future_date_message": "", "is_thumbnail": false, "licensetype": "license_free", "mimetype": "application/pdf", "size": 11100000.0, "url": {"label": "12_51-83.pdf", "url": "https://niigata-u.repo.nii.ac.jp/record/6894/files/12_51-83.pdf"}, "version_id": "ccb7643d-0484-4e86-944e-5f58ac23bd0c"}]}, "item_keyword": {"attribute_name": "\u30ad\u30fc\u30ef\u30fc\u30c9", "attribute_value_mlt": [{"subitem_subject": "Holocene", "subitem_subject_scheme": "Other"}, {"subitem_subject": "Diatom", "subitem_subject_scheme": "Other"}, {"subitem_subject": "Sedimentary environment", "subitem_subject_scheme": "Other"}, {"subitem_subject": "Lake Kamo", "subitem_subject_scheme": "Other"}, {"subitem_subject": "Sado Island", "subitem_subject_scheme": "Other"}]}, "item_language": {"attribute_name": "\u8a00\u8a9e", "attribute_value_mlt": [{"subitem_language": "eng"}]}, "item_resource_type": {"attribute_name": "\u8cc7\u6e90\u30bf\u30a4\u30d7", "attribute_value_mlt": [{"resourcetype": "departmental bulletin paper", "resourceuri": "http://purl.org/coar/resource_type/c_6501"}]}, "item_title": "Diatom Flora and paleoenvironment of Late Pleistocene and Holocene deposits of Lake Kamo, Sado Island, Central Japan", "item_titles": {"attribute_name": "\u30bf\u30a4\u30c8\u30eb", "attribute_value_mlt": [{"subitem_title": "Diatom Flora and paleoenvironment of Late Pleistocene and Holocene deposits of Lake Kamo, Sado Island, Central Japan"}, {"subitem_title": "Diatom Flora and paleoenvironment of Late Pleistocene and Holocene deposits of Lake Kamo, Sado Island, Central Japan", "subitem_title_language": "en"}]}, "item_type_id": "7", "owner": "1", "path": ["453/456", "176/177/178/202"], "permalink_uri": "http://hdl.handle.net/10191/47877", "pubdate": {"attribute_name": "\u516c\u958b\u65e5", "attribute_value": "2017-08-31"}, "publish_date": "2017-08-31", "publish_status": "0", "recid": "6894", "relation": {}, "relation_version_is_last": true, "title": ["Diatom Flora and paleoenvironment of Late Pleistocene and Holocene deposits of Lake Kamo, Sado Island, Central Japan"], "weko_shared_id": null}
