In northern Hiroshima Bay where the estuarine circulation driven by the river discharge is dominating, the amount of nutrient transported from the lower layer of southern area was large. It was estimated that the same amount of dissolved inorganic phosphorus (DIP) was transported from the lower layer of southern area, and was 50% for dissolved inorganic nitrogen (DIN). For the upper layer of northern bay, 12% of DIP was from the river, 44% was from the lower layer, and rest 44% was supplied by regeneration of organic matter in the system. Sensitivity analyses using a simple ecosystem model revealed that increase in DIP concentration both in the river water and in the water of the lower layer of southern area would enhance primary production higher than the amount of DIP increased. This may be due to the acceleration of regeneration in the system.","subitem_description_language":"en"}]},"item_1617186643794":{"attribute_name":"Publisher","attribute_value_mlt":[{"subitem_publisher":"日本海洋学会沿岸海洋研究部会"}]},"item_1617186702042":{"attribute_name":"Language","attribute_value_mlt":[{"subitem_language":"jpn"}]},"item_1617186920753":{"attribute_name":"Source Identifier","attribute_value_mlt":[{"subitem_source_identifier":"1342-2758","subitem_source_identifier_type":"ISSN"},{"subitem_source_identifier":"AN10492259","subitem_source_identifier_type":"NCID"}]},"item_1617187024783":{"attribute_name":"Page Start","attribute_value_mlt":[{"subitem_start_page":"137"}]},"item_1617187056579":{"attribute_name":"Bibliographic Information","attribute_value_mlt":[{"bibliographicIssueDates":{"bibliographicIssueDate":"2007-02","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"2","bibliographicPageEnd":"145","bibliographicPageStart":"137","bibliographicVolumeNumber":"44","bibliographic_titles":[{"bibliographic_title":"沿岸海洋研究"},{"bibliographic_title":"沿岸海洋研究"}]}]},"item_1617258105262":{"attribute_name":"Resource Type","attribute_value_mlt":[{"resourcetype":"journal article","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_1617265215918":{"attribute_name":"Version Type","attribute_value_mlt":[{"subitem_version_resource":"http://purl.org/coar/version/c_970fb48d4fbd8a85","subitem_version_type":"VoR"}]},"item_1617605131499":{"attribute_name":"File","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_access","date":[{"dateType":"Available","dateValue":"2023-03-18"}],"displaytype":"simple","filename":"BullCoastOceanogr_44-2_137.pdf","filesize":[{"value":"641.5 KB"}],"mimetype":"application/pdf","url":{"objectType":"fulltext","url":"https://hiroshima.repo.nii.ac.jp/record/2009248/files/BullCoastOceanogr_44-2_137.pdf"},"version_id":"1c7a5466-1bbd-4d41-acc1-182f47dc1657"}]},"item_1732771732025":{"attribute_name":"旧ID","attribute_value":"28947"},"item_title":"エスチュアリー循環と一次生産","item_type_id":"40003","owner":"41","path":["1730444907710"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2023-03-18"},"publish_date":"2023-03-18","publish_status":"0","recid":"2009248","relation_version_is_last":true,"title":["エスチュアリー循環と一次生産"],"weko_creator_id":"41","weko_shared_id":-1},"updated":"2025-02-22T05:14:46.603809+00:00"}
