This is also useful to develop quantitative evaluation techniques for passive acoustic monitoring. There have been limited studies on the acoustics of the Indo-Pacific humpback dolphin; nevertheless, this species is of particular concern because of the anthropogenic activity in the coastal habitats. In the present study, we used a four-hydrophone array to estimate the apparent source levels (ASLs) of biosonar sequences (click trains), of this species in San-Niang Bay, China. As the dolphins approached the array, 173 click trains were found to meet the criteria of on-axis sounds produced within 60 m of the equipment. In total, 121 unclipped click trains were used for the ASL estimation. The qualified click trains contained 36.3 ± 32.5 clicks, lasting for 1.5 ± 1.5 s, with average inter-click intervals (ICIs) of 51.2 ± 38.3 ms. Average ICIs showed a bimodal distribution, with a cut-off at 20 ms. Short-range click trains, with short ICIs of <20 ms on average, were characterized by smaller ASLs, relatively stable ICIs and a shorter click train duration. The mean back-calculated ASL for humpback dolphins with an approximately maximum body size of 2.5 m was 181.7 ± 7.0 dB re 1 μPa at a distance of 1.6–57.2 m. This value was comparable to that recorded for other dolphins of similar body size, although the ASL estimates obtained in this study might be conservative.","subitem_description_language":"en","subitem_description_type":"Abstract"}]},"item_10_description_5":{"attribute_name":"内容記述","attribute_value_mlt":[{"subitem_description":"Published online: 04 March 2014","subitem_description_language":"en","subitem_description_type":"Other"}]},"item_10_identifier_60":{"attribute_name":"URI","attribute_value_mlt":[{"subitem_identifier_type":"DOI","subitem_identifier_uri":"http://dx.doi.org/10.1017/S0025315414000071"},{"subitem_identifier_type":"HDL","subitem_identifier_uri":"http://hdl.handle.net/2237/24933"}]},"item_10_publisher_32":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"Cambridge University Press","subitem_publisher_language":"en"}]},"item_10_relation_11":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_type":"isVersionOf","subitem_relation_type_id":{"subitem_relation_type_id_text":"https://doi.org/10.1017/S0025315414000071","subitem_relation_type_select":"DOI"}}]},"item_10_select_15":{"attribute_name":"著者版フラグ","attribute_value_mlt":[{"subitem_select_item":"author"}]},"item_10_source_id_7":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"0025-3154","subitem_source_identifier_type":"PISSN"}]},"item_1615787544753":{"attribute_name":"出版タイプ","attribute_value_mlt":[{"subitem_version_resource":"http://purl.org/coar/version/c_ab4af688f83e57aa","subitem_version_type":"AM"}]},"item_access_right":{"attribute_name":"アクセス権","attribute_value_mlt":[{"subitem_access_right":"open access","subitem_access_right_uri":"http://purl.org/coar/access_right/c_abf2"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"Kimura, Satoko","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"67059","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Akamatsu, Tomonari","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"67060","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Fang, Liang","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"67061","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Wang, Zhitao","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"67062","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Wang, Kexiong","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"67063","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Wang, Ding","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"67064","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Yoda, Ken","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"67065","nameIdentifierScheme":"WEKO"}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2018-02-22"}],"displaytype":"detail","filename":"final_version_of_Kimura_et_al_SousaASL.pdf","filesize":[{"value":"773.7 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"final_version_of_Kimura_et_al_SousaASL.pdf","objectType":"fulltext","url":"https://nagoya.repo.nii.ac.jp/record/22774/files/final_version_of_Kimura_et_al_SousaASL.pdf"},"version_id":"8b0c00f7-d7c1-4909-ac5c-f6c79689bc6a"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"odontocete","subitem_subject_scheme":"Other"},{"subitem_subject":"echolocation signal","subitem_subject_scheme":"Other"},{"subitem_subject":"click train","subitem_subject_scheme":"Other"},{"subitem_subject":"buzz","subitem_subject_scheme":"Other"},{"subitem_subject":"inter-click interval","subitem_subject_scheme":"Other"},{"subitem_subject":"adjustment","subitem_subject_scheme":"Other"}]},"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":"Apparent source level of free-ranging humpback dolphin, Sousa chinensis, in the South China Sea","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Apparent source level of free-ranging humpback dolphin, Sousa chinensis, in the South China Sea","subitem_title_language":"en"}]},"item_type_id":"10","owner":"1","path":["490"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2016-09-30"},"publish_date":"2016-09-30","publish_status":"0","recid":"22774","relation_version_is_last":true,"title":["Apparent source level of free-ranging humpback dolphin, Sousa chinensis, in the South China Sea"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-01-16T04:12:16.149716+00:00"}
