The activity of Cs-137 on ammonium molybdophosphate was determined by gamma-spectrometry using a low background type high-purity Ge detector. Cs-137 activities in surface waters ranged from 2.4 to 2.8 mBq/L, showing the typical current activity level. The most striking feature is that a difference of Cs-137 activity, about a factor of 2-6, can be observed in the intermediate water (750-1250 m depth) between the Sulu Sea and South China Sea, i.e., the Cs-137 activities below 750-m depth in the Sulu Sea were significantly higher than those in the South China Sea. Furthermore, total inventory of 2930 Bq/m2 at the Sulu Sea was remarkably higher than that of 1740 Bq/m2 at the South China Sea. A possible mechanism controlling the high Cs-137 inventory in the Sulu Sea may be the inflow of the Cs-137 rich North Pacific Tropical Water and upper North Pacific Intermediate Water through the Mindoro Strait into the Sulu Sea, then conveyance into the deep layer in the Sulu Sea basin.","subitem_description_type":"Abstract"}]},"item_10005_description_6":{"attribute_name":"会議概要（会議名, 開催地, 会期, 主催者等）","attribute_value_mlt":[{"subitem_description":"American Geophysical Union 2006 Western Pacific Geophysics Meeting","subitem_description_type":"Other"}]},"item_access_right":{"attribute_name":"アクセス権","attribute_value_mlt":[{"subitem_access_right":"metadata only access","subitem_access_right_uri":"http://purl.org/coar/access_right/c_14cb"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"Yamada, Masatoshi"}],"nameIdentifiers":[{"nameIdentifier":"673362","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Wang, Zhong-Liang"}],"nameIdentifiers":[{"nameIdentifier":"673363","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Zheng, Jian"}],"nameIdentifiers":[{"nameIdentifier":"673364","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"山田 正俊","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"673365","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"王 中良","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"673366","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"鄭 建","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"673367","nameIdentifierScheme":"WEKO"}]}]},"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":"conference object","resourceuri":"http://purl.org/coar/resource_type/c_c94f"}]},"item_title":"High Cs-137 inventory in the Sulu and South China Seas","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"High Cs-137 inventory in the Sulu and South China Seas"}]},"item_type_id":"10005","owner":"1","path":["28"],"pubdate":{"attribute_name":"公開日","attribute_value":"2006-08-02"},"publish_date":"2006-08-02","publish_status":"0","recid":"68611","relation_version_is_last":true,"title":["High Cs-137 inventory in the Sulu and South China Seas"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-05-15T20:24:11.969367+00:00"}
