The three-dimensional position of the buoy was obtained by GPS every 30 s with a 4–5-cm precision for ca. 25 days. The height uncertainty of the 1-h averaged vertical position was ∼0.5 cm, even considering the uncertainties of un-modeled ocean loading effects. The daily evolution of north–south (NS), east–west (EW), and up–down (UD) motions shows periodic UD variations sometimes attaining an amplitude of 1 m. Observed amplitudes of tidal harmonics of major constituents were 88%–93% (O1) and 85%–88% (M2) of values observed in the global ocean tide models FES2004 and TPXO-8 Atlas. The basal melting rate of the iceberg is estimated to be ∼0.6 m/day, based on a firn densification model and using a quasi-linear sinking rate of the iceberg surface. The 30-s sampling frequency geodetic-mode GPS buoy helps to reveal ice–ocean dynamics around the calving front of Antarctic glaciers.","subitem_description_type":"Abstract"}]},"item_10001_description_6":{"attribute_name":"内容記述","attribute_value_mlt":[{"subitem_description":"白瀬氷河カービングフロント付近の氷山上に測位用2周波GPS受信機を設置し、GPSブイとして活用した。その30秒毎の3次元位置を、精度4—5 cmで、約25日間測定した。平滑化した1時間毎の上下成分(0.5 cm程度の不確定性を持つ)は海洋潮汐による周期変動を示し、海洋潮汐解析で得られた主要分潮の振幅は、FES2004やTPXO-8 Atlas海洋潮汐モデルの88%–93%(O1分潮)や85%–88%(M2分潮)の値を持つ。氷山表面の沈降率とフィルン圧密モデルから、氷山底面の融解速度、0.6 m/dayが推定された。このように氷山を活用したGPSブイは、カービングフロント付近の氷・海洋ダイナミクスを明らかにするのに役立つ。","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.2016.02.005"}],"subitem_relation_type_id":{"subitem_relation_type_id_text":"http://doi.org/10.1016/j.polar.2016.02.005","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":"Aoyama, Yuichi","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"35403","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Kim, Tae-Hee","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"35404","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Doi, Koichiro","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"35405","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Hayakawa, Hideaki","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"35406","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Higashi, Toshihiro","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"35407","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Ohsono, Shingo","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"35408","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Shibuya, Kazuo","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"35409","nameIdentifierScheme":"WEKO"}]}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"Vertical tidal motion by GPS-buoy","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Fluctuating horizontal flow","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Tidal harmonic","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Global ocean tide model","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Subsidence by basal melting","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":"Observations of vertical tidal motions of a floating iceberg in front of Shirase Glacier, East Antarctica, using a geodetic-mode GPS buoy","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Observations of vertical tidal motions of a floating iceberg in front of Shirase Glacier, East Antarctica, using a geodetic-mode GPS buoy"},{"subitem_title":"Observations of vertical tidal motions of a floating iceberg in front of Shirase Glacier, East Antarctica, using a geodetic-mode GPS buoy","subitem_title_language":"en"}]},"item_type_id":"10001","owner":"36","path":["1672"],"pubdate":{"attribute_name":"公開日","attribute_value":"2016-05-31"},"publish_date":"2016-05-31","publish_status":"0","recid":"12704","relation_version_is_last":true,"title":["Observations of vertical tidal motions of a floating iceberg in front of Shirase Glacier, East Antarctica, using a geodetic-mode GPS buoy"],"weko_creator_id":"36","weko_shared_id":-1},"updated":"2023-07-25T16:04:12.457677+00:00"}
