Calcium (Ca) content of the sediment was significantly enhanced with increasing distance from inmost of the bays. Digital image analysis was used to valuate the sediment diameter and its image colors. Spatial characteristics of the sediment were grouped into some zones along the bays using cluster analysis.","subitem_description_language":"en","subitem_description_type":"Other"}]},"item_10001_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"公益社団法人 土木学会","subitem_publisher_language":"ja"},{"subitem_publisher":"Japan Society of Civil Engineers","subitem_publisher_language":"en"}]},"item_10001_relation_14":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"10.2208/jscejoe.73.I_1036"}}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"岡辺 拓巳","creatorNameLang":"ja"},{"creatorName":"OKABE Takumi","creatorNameLang":"en"}]},{"creatorNames":[{"creatorName":"村上 智一","creatorNameLang":"ja"},{"creatorName":"MURAKAMI Tomokazu","creatorNameLang":"en"}]},{"creatorNames":[{"creatorName":"河野 裕美","creatorNameLang":"ja"},{"creatorName":"KOHNO Hiroyoshi","creatorNameLang":"en"}]},{"creatorNames":[{"creatorName":"水谷 晃","creatorNameLang":"ja"},{"creatorName":"MIZUTANI Akira","creatorNameLang":"en"}]},{"creatorNames":[{"creatorName":"下川 信也","creatorNameLang":"ja"},{"creatorName":"SHIMOKAWA Shinya","creatorNameLang":"en"}]}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"jpn"}]},"item_title":"蛍光X線分析と画像解析による崎山湾・網取湾自然環境保全地域での底質分布の把握","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"蛍光X線分析と画像解析による崎山湾・網取湾自然環境保全地域での底質分布の把握","subitem_title_language":"ja"},{"subitem_title":"SPATIAL CHARACTERIZATION OF COASTAL SEDIMENT IN SAKIYAMA AND AMITORI BAYS BY X-RAY FLUORESCENCE AND DIGITAL IMAGE ANALYSIS","subitem_title_language":"en"}]},"item_type_id":"40001","owner":"1","path":["1670839190650"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2023-04-27"},"publish_date":"2023-04-27","publish_status":"0","recid":"3737","relation_version_is_last":true,"title":["蛍光X線分析と画像解析による崎山湾・網取湾自然環境保全地域での底質分布の把握"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-04-27T05:19:50.315682+00:00"}
