They migrate to high-latitude feeding grounds each spring. Their main feeding grounds in the Arctic include the Chirikov Basin, the northeastern Chukchi Sea from Pt. Hope to Cape Lisburne and Pt. Lay to Pt. Barrow, and the northwestern Chukchi Sea along the Chukotka coast. Although sightings are rare in the Canadian Beaufort Sea, we observed three gray whales in two groups in this area in September 2014. A mud plume was observed near one of the whales, suggesting the animal had been feeding. In the Alaskan Beaufort Sea, large-scale monitoring of the distributions of marine mammals has been continuously conducted since 1979; however, there has been less monitoring in the Canadian Beaufort Sea. Therefore, it is necessary to record opportunistic sightings, such as those described here.","subitem_description_type":"Abstract"}]},"item_10001_description_6":{"attribute_name":"内容記述","attribute_value_mlt":[{"subitem_description":"コククジラEschrichtius robustusは北太平洋やベーリング海、チャクチ海の生産性の高い浅海域や河口に分布しており、毎年春になると高緯度海域へ摂餌のために北上回遊する。ボーフォート海東部のカナダ沿岸海域では本種の発見は非常に珍しいが、2014年9月に3頭のコククジラが発見された。その内の1頭の発見位置付近では、海底でベントスを摂餌した証拠である泥の巻き上がりが確認され、本種がこの海域を摂餌海域として利用していることが考えられた。ボーフォート海西部のアラスカ沿岸海域では、1979年から継続的に広域の海棲哺乳類の分布調査が行われてきたが、今回の発見海域であるボーフォート海東部のカナダ沿岸海域では分布調査がほとんど行われていないため、本報告のような偶発的な発見の記録が非常に重要である。","subitem_description_type":"Other"}]},"item_10001_relation_14":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_name":[{"subitem_relation_name_text":"10.1016/j.polar.2016.04.007"}],"subitem_relation_type_id":{"subitem_relation_type_id_text":"http://doi.org/10.1016/j.polar.2016.04.007","subitem_relation_type_select":"DOI"}}]},"item_10001_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"18739652","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":"Iwahara, Yuka","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"35427","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Fujiwara, Amane","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"35428","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Ito, Keizo","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"35429","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Miyashita, Kazushi","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"35430","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Mitani, Yoko","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"35431","nameIdentifierScheme":"WEKO"}]}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"Gray whale","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Eastern Beaufort Sea","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Eschrichtius robustus","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Feeding","subitem_subject_language":"en","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":"Gray whale sightings in the Canadian Beaufort Sea, September 2014","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Gray whale sightings in the Canadian Beaufort Sea, September 2014"},{"subitem_title":"Gray whale sightings in the Canadian Beaufort Sea, September 2014","subitem_title_language":"en"}]},"item_type_id":"10001","owner":"36","path":["1672"],"pubdate":{"attribute_name":"公開日","attribute_value":"2016-06-01"},"publish_date":"2016-06-01","publish_status":"0","recid":"12709","relation_version_is_last":true,"title":["Gray whale sightings in the Canadian Beaufort Sea, September 2014"],"weko_creator_id":"36","weko_shared_id":-1},"updated":"2023-07-25T16:04:08.155139+00:00"}
