We show that the joint processing of data from the combined seismic networks of all these institutions leads to a considerable increase in the number of located seismic events in the European Arctic compared to standard seismic bulletins such as the NORSAR reviewed regional seismic bulletin and the Reviewed Event Bulletin (REB) issued by the International Data Centre (IDC) of the Comprehensive Nuclear-Test-Ban Treaty (CTBT) organization. The increase is particularly pronounced along the Gakkel Ridge to the north of the Svalbard and Franz-Josef Land archipelagos. We also note that the vast majority of the events along the Gakkel Ridge have been located slightly to the south of the ridge. We interpret this as an effect of the lack of recording stations closer to and north of the Gakkel Ridge, and the use of a one-dimensional velocity model which is not fully representative for travel-times along observed propagation paths. We conclude that while the characteristics of earthquake activity in the European Arctic is currently poorly known, the knowledge can be expected to be significantly improved by establishing the appropriate cooperative seismic recording infrastructures.","subitem_description_type":"Abstract"}]},"item_10001_description_6":{"attribute_name":"内容記述","attribute_value_mlt":[{"subitem_description":"この論文では、ノルウェー地震アレイ研究所（NORSAR)と北西ロシア地震研究所（Arkhangelsk and Apatity)との共同研究による初期成果を示す。関連する全研究所の地震観測網で得られた統合データの合同処理により、NORSARの再読取りによる地震報告や包括的核実験禁止条約観測網（CTBT)の国際データセンター（IDC)による再験震イベント（REB)等の標準的な地震カタログと比べて、ヨーロッパ北極域に分布する地震イベント数が顕著に増加した。特にスバールバールやフランツヨゼフランド諸島の北方に位置するガケル海嶺（Gakkel Ridge）で顕著である。さらに、ガケル海嶺沿いの地震の大部分は、海嶺の少し南側に震源が求められた。このことは、海嶺の近傍及び北側に観測点が欠落し、かつ使用した1次元速度モデルが観測される波動伝搬経路の走時を十分に代表していない、ことの影響と思われる。ヨーロッパ北極域の地震活動の特徴は現在でもあまり分かっていないが、適切な共同地震観測網の構築で大きく改善された、と結論づけられる。","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.2014.08.003"}],"subitem_relation_type_id":{"subitem_relation_type_id_text":"http://doi.org/10.1016/j.polar.2014.08.003","subitem_relation_type_select":"DOI"}}]},"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":"Galina Antonovskaya"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Yana Konechnaya"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Elena O.
