We call this “underwater tempura noise”. It is said that the burst-wave undulation occurs through an outbreak of air bubbles caused by the rapid closing of one-side of the greatly developed claw of the snapping shrimp. Although the shrimp’s claw noise has been consistently treated as a nuisance noise, studies of ambient noise imaging (acoustic daylight imaging) were recently performed, where the noise was positively used as a sound source. However, details of the distribution situation or outbreak frequency of the ambient noise itself are still unc lear and an evaluation method for counting the number of pulses has also not been established yet. When considering ambient noise imaging, the position relations between the sound source, target and receiver are extremely important, that is, it becomes necessary to grasp how much ambient noise is emitted in the actual sea area, rather than when or where.\nIn this study, we added new improvements to measurement and analysis method for counting the number of pulses that had been suggested before, we investigated the distribution of the ambient noise at the sea areas around the Japan Coast Guard Academy and performed 5-days of consecutive observation at a fixed-point in summer, winter, and spring.","subitem_description_type":"Abstract"}]},"item_10002_identifier_registration":{"attribute_name":"ID登録","attribute_value_mlt":[{"subitem_identifier_reg_text":"10.15053/0000000090","subitem_identifier_reg_type":"JaLC"}]},"item_10002_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"海上保安大学校"}]},"item_10002_relation_14":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_type":"isIdenticalTo","subitem_relation_type_id":{"subitem_relation_type_id_text":"10.15053/2022.21.01","subitem_relation_type_select":"DOI"}}]},"item_10002_source_id_11":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AN10088865","subitem_source_identifier_type":"NCID"}]},"item_10002_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"0287-2951","subitem_source_identifier_type":"ISSN"}]},"item_10002_version_type_20":{"attribute_name":"著者版フラグ","attribute_value_mlt":[{"subitem_version_resource":"http://purl.org/coar/version/c_970fb48d4fbd8a85","subitem_version_type":"VoR"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"倉本, 和興"},{"creatorName":"クラモト, カズオキ","creatorNameLang":"ja-Kana"},{"creatorName":"KURAMOTO, Kazuoki","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"70","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"田中, 隆博"},{"creatorName":"タナカ, タカヒロ","creatorNameLang":"ja-Kana"},{"creatorName":"TANAKA, Takahiro","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"171","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":"2023-04-05"}],"displaytype":"detail","filename":"2_65-1-88-01_Kuramoto.pdf","filesize":[{"value":"2.0 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"テッポウエビ類が発するパルス性雑音の分布状況の調査と定点観測","url":"https://jcga.repo.nii.ac.jp/record/90/files/2_65-1-88-01_Kuramoto.pdf"},"version_id":"01dae971-a388-4f99-926c-9bff884187f4"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"Underwater Acoustic","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Ambient Noise","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Marine Environmental Value","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Number of Pulses","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Snapping Shrimp","subitem_subject_language":"en","subitem_subject_scheme":"Other"}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"jpn"}]},"item_resource_type":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"resourcetype":"departmental bulletin paper","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"テッポウエビ類が発するパルス性雑音の分布状況の調査と定点観測","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"テッポウエビ類が発するパルス性雑音の分布状況の調査と定点観測","subitem_title_language":"ja"},{"subitem_title":"Investigation of the distribution and fixed-point observation of the ambient noise derived from snapping shrimps","subitem_title_language":"en"}]},"item_type_id":"10002","owner":"5","path":["30"],"pubdate":{"attribute_name":"公開日","attribute_value":"2023-04-05"},"publish_date":"2023-04-05","publish_status":"0","recid":"90","relation_version_is_last":true,"title":["テッポウエビ類が発するパルス性雑音の分布状況の調査と定点観測"],"weko_creator_id":"5","weko_shared_id":-1},"updated":"2023-10-03T22:24:13.128864+00:00"}
