We sampled groundwaters along six inferred regional groundwater flow paths in the Great Artesian Basin (GAB) of Australia. We selected three groundwater paths where the decrease in Cl-36 was largely controlled by cosmogenic Cl-36 radioactive decay without a significant increase in chloride concentration. The extrapolated groundwater velocities were 0.133+-0.018 m/y to 0.433+-0.140 m/y. The estimated residence time of 1.06x10^6 y at the discharge area around Lake Eyre was comparable to the estimate of (1-2.2) x 10^6 y in previous studies. On the other hand, our estimated He-4 accumulation rates for the selected three groundwater flow paths (1.85+-0.31x10^-1 to 1.51+-0.63x10^-10 ccSTP/cm^3/y) were approximately 2-5 times lower than previously reported rates for the central GAB. Our estimated rate of 1.51x10^-10 ccSTP/cm^3/y in the western GAB is compatible with previous estimates based on Kr-81 ages. The groundwater residence time estimated from the He-4 accumulation rate was approximately 7x10^5 y near the discharge area at Lake Eyre. Finally, both estimations were mutually compatible with a 30% error.","subitem_description_type":"Abstract"}]},"item_8_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"0012-821X","subitem_source_identifier_type":"ISSN"}]},"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":"Mahara, Yasunori"}],"nameIdentifiers":[{"nameIdentifier":"453821","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Habermehl, M.A."}],"nameIdentifiers":[{"nameIdentifier":"453822","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Hasedawa, Takuma"}],"nameIdentifiers":[{"nameIdentifier":"453823","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Nakata, Koutarou"}],"nameIdentifiers":[{"nameIdentifier":"453824","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Ransley, T.R."}],"nameIdentifiers":[{"nameIdentifier":"453825","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Hatano, T"}],"nameIdentifiers":[{"nameIdentifier":"453826","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Mizuochi, Yukihiro"}],"nameIdentifiers":[{"nameIdentifier":"453827","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Kobayashi, Hidemitu"}],"nameIdentifiers":[{"nameIdentifier":"453828","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Ninomiya, A"}],"nameIdentifiers":[{"nameIdentifier":"453829","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Senior, B.R."}],"nameIdentifiers":[{"nameIdentifier":"453830","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Yasuda, Hiroshi"}],"nameIdentifiers":[{"nameIdentifier":"453831","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Ohta, T"}],"nameIdentifiers":[{"nameIdentifier":"453832","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"保田 浩志","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"453833","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":"journal article","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"Groundwater dating by estimation of groundwater flow velocity and dissolved 4He accumulation rate calibrated by 36Cl in the Great Artesian Basin, Australia","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Groundwater dating by estimation of groundwater flow velocity and dissolved 4He accumulation rate calibrated by 36Cl in the Great Artesian Basin, Australia"}]},"item_type_id":"8","owner":"1","path":["1"],"pubdate":{"attribute_name":"公開日","attribute_value":"2009-11-04"},"publish_date":"2009-11-04","publish_status":"0","recid":"45668","relation_version_is_last":true,"title":["Groundwater dating by estimation of groundwater flow velocity and dissolved 4He accumulation rate calibrated by 36Cl in the Great Artesian Basin, Australia"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-05-16T00:01:02.992106+00:00"}
