One is wind-induced noise which is detected directly by a seismometer. This type of noise increases with a wind velocity, and when the wind velocity is over 15 m/s, seismic observations are not in success. With the object of noise reduction, seismometers buried in a hole at depths of 3, 5 and 10 m were examined, but the noise existed at 10 m. Seismometers should be buried deeper than 10 m. Another is electrostatic noise which frequently deranges a clock signal or destroys an electric circuit in the worst case. This noise is caused by drifting electrified snow, not by a seismometer itself. It was excited on a signal cable stretched on the snow surface from the seismometer to a recorder. To reduce this noise, the cable should be as short as possible and be laid in parallel with the direction of wind.","subitem_description_type":"Other"}]},"item_1_source_id_13":{"attribute_name":"雑誌書誌ID","attribute_value_mlt":[{"subitem_source_identifier":"AA00733470","subitem_source_identifier_type":"NCID"}]},"item_1_text_10":{"attribute_name":"著者所属(英)","attribute_value_mlt":[{"subitem_text_language":"en","subitem_text_value":"Rogional Center for Earthquake Prediction Observation,School of Science,Nagoya University"},{"subitem_text_language":"en","subitem_text_value":"Rogional Observation Center for Earthquake Prediction,Faculty of Science,Kyoto University"}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"1984-02-01"}],"displaytype":"detail","filename":"KJ00000011323.pdf","filesize":[{"value":"1.0 MB"}],"format":"application/pdf","licensetype":"license_6","mimetype":"application/pdf","url":{"label":"KJ00000011323","url":"https://nipr.repo.nii.ac.jp/record/638/files/KJ00000011323.pdf"},"version_id":"7a4acc65-2ebe-48f9-ab4b-7658400271ce"}]},"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":"departmental bulletin paper","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"Nature of noises on ice sheet in East Antarctica","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Nature of noises on ice sheet in East Antarctica","subitem_title_language":"en"}]},"item_type_id":"1","owner":"4","path":["322"],"pubdate":{"attribute_name":"公開日","attribute_value":"1984-02-01"},"publish_date":"1984-02-01","publish_status":"0","recid":"638","relation_version_is_last":true,"title":["Nature of noises on ice sheet in East Antarctica"],"weko_creator_id":"4","weko_shared_id":4},"updated":"2023-07-25T14:12:45.926391+00:00"}
